HYDROXAMTC ACID SUBSTITUTED FUSED
HFTFROCYCLIC METALLOPROTEINASE INHIBITORS
BACKGROIIND OF THE INVENTION
This application claims the benefit of U.S.
Provisional Application No. 60/054,753 filed August 4,
1997, which is hereby incorporated by reference. The
present invention relates to metalloproteinase
inhibitors and more particularly, relates to novel
compounds, composition and method for prophylaxis and
treatment of inflammation, tissue degradation and the
like. This invention, in particular, relates to novel
hydroxamic acid substituted fused heterocyclic
compounds, compositions containing such compounds and
methods of use of such compounds. The subject invention
also relates to processes for making such compounds as
well as to intermediates useful in such processes.
Metalloproteinase enzymes, such as collagenases
(e. g., MMP-1, MMP-8 and MMP-13), stromelysins (e. g.,
MMP-3, MMP-10, MMp-11 and MMP-7), gelatinases (e. g.,
MMP-2 and MMP-9) and TNF convertase, may contribute to
the onset, etiology, or exacerbate disease states which
are related to connective tissue degradation, secretion
of proinflammatory cytokines and the like. For example,
matrix metalloproteinases, such as collagenases,
stromelysins and gelatinases, are thought to be involved
in the tissue breakdown observed in rheumatoid
arthritis; osteoarthritis; osteopenias (e. g.,
osteoporosis); periodontitis; gingivitis; corneal,
epidermal and gastric ulceration; and tumour metastasis,
invasion and growth; in neuroinflammatory disorders,
such as myelin degradation (e. g., multiple sclerosis).
and in angiogenesis dependent diseases, such as
arthritic conditions; solid tumor growth; psoriasis;
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147

proliferative retinopathies; neovascular glaucoma;
ocular tumours; angiofibromas; and hemangiomas.
Tumor Necrosis Factor alpha (TNF-a) is a
proinflammatory cytokine secreted by a variety of cells
including monocytes and macrophages in response to many
inflammatory stimuli (e.g. lipopolysaccharide - LPS) or
external cellular stress (e. g. osmotic shock, peroxide).
Elevated levels of TNF play a major role in mediating
many inflammatory disease states. Elevated levels of
TNF-a may contribute to the onset, etiology, or
exacerbate the following disease states: rheumatoid
arthritis; osteoarthritis; rheumatoid spondylitis; gouty
arthritis; inflammatory bowel disease; adult respiratory
distress syndrome CARDS); psoriasis; Crohn's disease;
allergic rhinitis; ulcerative colitis; anaphylaxis;
contact dermatitis; asthma; antiviral therapy including
those viruses sensitive to TNF-a inhibition - HIV-1,
HIV-2, HIV-3, cytomegalovirus (CMV), influenza,
adenovirus, and the herpes viruses including HSV-1, HSV-
2, and herpes zoster; muscle degeneration; cachexia;
Reiter's syndrome; type II diabetes; bone resorption
diseases; graft vs. host reaction; ischemia reperfusion
injury; atherosclerosis; brain trauma; Alzheimer's
disease; multiple sclerosis; cerebral malaria; sepsis;
septic shock; toxic shock syndrome; fever and mylagias
due to infection.
Several approaches have been taken to block the
effects of TNF-a. One approach involves utilizing
soluble receptors for TNF-a (e. g., TNFR-55 or TNFR-75)
which have demonstrated efficacy in animal models of
TNF-a mediated disease states. A second approach to
neutralizing TNF-a utilizing a monoclonal antibody
specific to TNF-a, cA2, has demonstrated improvement in
swollen joint count in a Phase II human trial of
rheumatoid arthritis (Feldmann et al Immunological
Reviews p.195-223 (1995)).
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147

The above approaches block the effects of TNF-a by
either protein sequesterazation or receptor antagonism,
but an additional approach to blockade is to intervene
in the cellular secretion of TNF. TNF convertase is
thought to be a metalloproteinase enzyme involved in the
cellular secretion of TNF-a (Mohler et al., Nature
370:218-220, 1994; Gearing et al., Nature 370:555-557,
1994; McGeehan et al., Nature 370:558-561, 1994).
Inhibition of TNF convertase is thought to be an
additional approach to intervene in the cellular
secretion of TNF-a. For example, a metalloproteinase
inhibitor was shown to inhibit cellular secretion of
TNF-a, in vitro and in vivo, which was thought to be due
to inhibition of TNF convertase (McGeehan et al., Nature
370:558-561, 1994). WO 92/02822, WO 94/00555, WO
95/24501, WO 96/41624, WO 98/02557 and US Pat. 5,594,106
(each of which is incorporated herein by reference in
its entirety) describe a TNF-a convertase and methods of
identifying inhibitors thereof. V~Thile evidence as to
the nature of intervention by metalloproteinase
inhibitors in the cellular secretion of TNF-a exists,
additional or alternative mechanisms of action by which
such compounds inhibit TNF secretion may be involved,
such as by intervening at a point on the pathway between
extracellular stimulus and secretion of protein.
Since TNF-a is upstream in the cytokine cascade of
inflammation wherein elevated levels of TNF-a lead to
elevated levels of other cytokines including IL-1, IL-6
and IL-8, inhibiting the secretion of TNF-a may also
reduce levels of other cytokines including but not
limited to IL-1, IL-6 or IL-8.
Further, TNF-a is thought to play a role in head
trauma, stroke, and ischemia. For instance, in animal
models of head trauma (rat), TNF-a levels increased in
the contused hemisphere (Shohami et al J. Cereb. Blood
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147
4
Flow Metab. 14:615-619 (1994)). In an model of ischemia
wherein the middle cerebral artery was occluded in rats,
the levels of mRNA of TNF-a increased (Feurstein et al
Neurosci. Lett. 164:125-128 (1993)). Administration of
TNF-a into the rat cortex resulted in significant PMN
accumulation in capillaries and adherance in small blood
vessels. TNF-a promotes the infiltration of other
cytokines (IL-1b, IL-6), and also chemokines, which
promote neutrophil infiltration into the infarct area
(Feurstein Stroke 25:1481-1488 (1994)).
TNF-a may also play a role in promoting certain
viral life cycles and disease states associated with
them. For instance, TNF-a secreted by monocytes induced
elevated levels of HIV expression in a chronically
infected T cell clone (Clouse et al, J. Immunol. 142:431
(1989)). The role of TNF-a in the HIV associated states
of cachexia and muscle degradation has been discussed
(Lahdevirta et al The American J. Med. 85:289 (1988)).

the formation of an addition salt, such as
hydrochloride, toluenesulfonic acid, trifluoroacetic
acid and the like. Many of the amino protecting groups

ether function is readily accomplished by treatment
with, for example, a metal hydroxide or ammonium
flouride reagent, either as a discrete reaction step or
in situ during a reaction with the alcohol group.
Suitable silylating agents are, for example, trimethyl-
silyl chloride, tert-buty-dimethylsilyl chloride,
phenyldimethylsilyl chloride, diphenylmethyl silyl
chloride or their combination products with imidazole or
DMF. Methods for silylation of amines and removal of
silyl protecting groups are well known to those skilled
in the art. Methods of preparation of these amine
derivatives from corresponding amino acids, amino acid
amides or amino acid esters are also well known to those
skilled in the art of organic chemistry including amino
acid/amino acid ester or aminoalcohol chemistry.
Protecting groups are removed under conditions
which will not affect the remaining portion of the
molecule. These methods are well known in the art and
include acid hydrolysis, hydrogenolysis and the like. A
preferred method involves removal of a protecting group,
such as removal of a benzyloxycarbonyl group by
hydrogenolysis utilizing palladium on carbon in a
suitable solvent system such as an alcohol, acetic acid,
and the like or mixtures thereof. A t-butoxycarbonyl
protecting group can be removed utilizing an inorganic
or organic acid, such as HC1 or trifluoroacetic acid, in
a suitable solvent system, such as dioxane or methylene
chloride. The resulting amino salt can readily be
neutralized to yield the free amine. Carboxy protecting
group, such as methyl, ethyl, benzyl, tert-butyl, 4-
methoxyphenylmethyl and the like, can be removed under
hydroylsis and hydrogenolysis conditions well known to
those skilled in the art.

J. Heterocycles, 1~, 1982), can give the bicyclic
intermediate (3). The acid functionality of the
bicyclic intermediate (3) (when Pl is H) is then be
converted into an ester using standard procedures (for
10 example HC1 and methanol). The protected bicyclic
intermediate (3) is then sulfonylated under Schotten-
Baumann conditions to furnished the sulfonamide (4).
Sulfonamide (4) (when R9 is H) may be halogenated, such
as iodinated, and then carbonylated (See for example
15 Schoenberg, A., et al, J.Org.Chem., ~9, 3318, (1974)))
and subsequently derivatised, amidated (See for example
Corey, E.J. and Hegedus, L.S., J.Am.Chem.Soc., 91, 1233
(1969)), arylated or alkylated (See for example Stille,
J.K., Angew. Int. Ed. Engl., ,~5, 508 (1986)) to yield
20 sulfonamide (4) where R9 is other than H. Sulfonamide
(4) can be readily converted into the corresponding
hydroxamic acids (5) using procedures well known to
those skilled in the art. Alternatively, R11 and/or R12
may be introduced into sulfonamide (4), where R11 and/or
25 R1~ are independently a leaving group (L' and L",
respectively) utilizing suitably functionalized
nucleophilic species (such as RaISH or R'3NHa followed by
reaction with the electrophile R'1N=C=O, R'zR'1N-C (0) -L,
R"-C (0) -L, R'°-SOZ-L, R'ZR31N-SOz-L, and the like) and/or a

utilizing suitably functionalized electrophilic species
(Such aS R'1N=C=0, R'ZR"N-C (0) -L, R'°-L, Rzz-C (O) -L arid the
like), where L, L' and L" are each a leaving group, such
as chloro, bromo, iodo, mesylate, tosylate and the like.
35 When R11 or R12 is a hydroxy, amino, substituted amino or
thiol group, the groups may require selective protection
and de-protection, using reagents and methods well known

and the like, where L is a leaving group, such as
chloro, bromo, iodo, mesylate, tosylate and the like, to
generate sulfonamide (10b). (See for example Duggan,
M.E. and Imagrire J.S., Synthesis 131 (1989)).
Sulfonamide (10b) can be readily converted into the
corresponding hydroxamic acid (11) using procedures well
known to those skilled in the art. Alternatively, the

like), mesyl chloride, tosyl chloride, and the like,
where L is a leaving group, such as chloro, bromo, iodo,
mesylate, tosylate and the like, to generate sulfonamide

For example, as shown in Scheme IX, an
appropriately 3,4-substituted thiophene carboxaldehye
(25), wherein Pa is a hydroxy protecting group, may be
condensed, under basic conditions (for example in the
presence of LDA in THF) with a protected N-
sulphonylated glycine (26), wherein P1 is a carboxylic
acid protecting group such as an ester and the like,
to give beta-hydroxy amino acid (27) (see for example
Dikshit, D.K., et al. Tet. Lett. 1988, 29(25), 3109-
3110). The beta-hydroxy amino acid (27) may then be
protected with a hydroxy protecting group P3 such as by
acylation of the beta-hydroxy group and separated into
threo and erythro diastereomers. PZ may then be
removed and Mitsonobu cyclization conditions can give
intermediate (28). P1 may then be removed, a
hydroxamic acid formed and P3 removed to give (29a)
utilizing methodology familiar to one skilled in the
art. Alternatively, (28) may be deprotected to the
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147
beta-hydroxy acid and converted to beta-carbamoyl
hydroxamate (29b) or other substituted oxy group
(i.e., -OR'°) compound (29c) again utilizing
methodology familiar to one skilled in the art. This
5 general scheme is also applicable for other
substituted heterocyclic carboxaldehydes as shown in
Scheme X to form six, seven and eight membered
heterocyclic fused compounds (I) of this invention.
Scheme XI illustrates an alternative general
10 synthesis (Claisen ring contraction) useful for the
preparation of the novel compounds of this invention as
illustrated in Scheme IV whereby an appropriately
substituted heterocycle (14) is cyclized into bicyclic
intermediate (15). As shown in Scheme XI, heterocycle
15 (31) can be prepared by coupling electrophile (30),
wherein R8 is - (CHZ)m-L° (m = 0-1) or a group which can be
converted into - (CHZ),~-Le and wherein Rf is W or a group
which can be converted into W during the synthesis of
the compounds of this invention, with the protected N-
20 sulphonylated glycine (26), wherein P1 is a carboxylic
acid protecting group such as an ester and the like,
(for example, a Mitsunobu coupling, Syn. 1981:1-28).
When Re is a leaving group, such as bromine atom, Re can
be converted into -(CH2)m-La by a homologation sequence
25 (for example, for m = 1 and La - Br, Palladium catalyzed
Stille coupling of tributylvinyltin with the heterocycle
(31) (Re - Br), followed by oxidative cleavage (OsO,,
NaIOa) of the resulting vinyl group to form an aldehyde
group (Re - -CHO), reduction with NaBH4 to an alcohol
30 group (Re - -CHZOH), and finally bromination of the
alcohol (NBS and PPh,) to form the desired heterocycle
(32) (m = 1, L8 - Br) ) .
The Z-allylic alcohol (33) can be prepared by
coupling (Z) -Bu3SnCH=CHCHZOTBS, which has been
35 synthesized and utilized in both its protected and
unprotected forms (Corey et al., Tet. Lett. 25:2419-2422
(1984); Jung et al., Tet. Lett. 23:3851-3854 (1982); and
*rB

76
Stille et al., J. Am. Chem. Soc. 109:813-817 (1987)),
with heterocycle (32). The coupling can be performed
utilizing PdCl2(PPh3)2 catalyzed Stille reaction (Stille,
Chem. Int. Ed. Engl. 25:508-524 (1986); and Stille et
al., J. Am. Chem. Soc. 101:4992-4998 (1979)).
Alternatively, (Z) -Bu3SnCH=CHCHZOTBDMS (prepared from
commercially available ethyl cis-3-iodoarylate by
reduction with about two equivalents of DIBAL-H (Beruben
et al., J. Org. them. 60:2488-2501 (1995)) by slow
addition at about -78°C to minimize double bond
isomerization during the reaction followed by gradual
warming to ambient temperature, the resulting iodo-
alcohol is protected as its TBDMS ether and then
subjected to halogen-metal exchange (butyl lithium and
tributyltin chloride, Pearson et al., J. Org. Chem.
59:5662-5671 (1994)) to give the desired (Z)-
Bu3SnCH=CHCHzOTBDMS) is utilized in the coupling
reaction. The Z-allylic alcohol (33) then results
following deprotection of the carboxylic acid (such as
with KOH in THF) and the TMS group (such as with acid)
or the TBDMS group (such as with TBAF in THF).
The lactone (34) is then prepared from the Z-
allylic alcohol (33). Many methods that are available
to form medium to large lactones (Meng et al., "Topics
in Current Chemistry, Ring Closure Methods in the
Synthesis of Macrocyclic Natural Products," Springer-
Verlag (Pub.), Vol. 161 (1991); and Nicolaou,
Tetrahedron 33:683-710 (1977)). For example, the
lactone (34) can be prepared from the Z-allylic alcohol
(33) utilizing Mukaiyama's reagent (Mukaiyama et al.,
Chem. Lett. 1976:49-50; and Mukaiyama, Chem. Int. Ed.
Engl. 18:707-721 (1979)) under high dilution conditions

Claisen ring contraction of the lactone (34) can be
effected by treatment of the lactone with various
combinations of reagents including TBDMSC1/LDA,
TBDMSOTf/LHMDS and TBDMSOTf/KHMDS, such as in THF at
about -78°C (Ireland et al., J. Am. Chem. Soc. 98:2868-
2877 (1976)) followed by heating the reaction, for
example to reflux, to give the Claisen product as a

78
protected carboxylic acid which can be deprotected, such
as with , to yield the heterocycle carboxylic acid (35).
Any silyl ester of the heterocycle carboxylic acid (35)
produced in the reaction can be removed by treatment
with aqueous KZC03 in THF-MeOH to give the free the
heterocycle carboxylic acid (35).
The relative stereochemistry between the vinyl and
carboxylic acid groups of the heterocycle carboxylic
acid (35) may be cis (Abelman et al., J. Am. Chem. Soc.
104:4030-4032 (1982); Funk et al., Tetrahedron 42:2831-
2845 (1986); and Corey et al., J. Am. Chem. Soc.
118:1229-1230 (1996)). The carboxylic acid group of the
heterocycle carboxylic acid (35) or the corresponding
ester can be epimerized, for example by treatment with
base, and the resulting cis and trans diasteriomers can
be separated and the R and S enantiomers can be
separated using methods well known to those skilled in
the art. The 2-trimethylsilylethyl protecting group can
be removed from the carboxylic acid group without
substantial epimerization from the cis stereochemistry
with fluoride in the presence of DMAP. The hydroxamic
acids (I) of this invention can then be prepared from
the heterocycle carboxylic acid (35) using PyBroP,
NHZOH~HCl and Hunigs base in CH2C12.
The alkene group of the heterocycle carboxylic acid
(35) can be functionalize using methods well known in
the art to produce a variety of groups. A recent
methodology described by Suzuki et al. CChem. Rev.
95:2457-2483 (1995)), which involves palladium catalyzed
coupling of alkylborane derivatives with alkenyl or aryl
halides or triflates. For example, coupling of the
hydroboration product of an ester of heterocycle
carboxylic acid (35) with iodobenzene can yield
heterocycles substituted with a phenethyl group. This
functionalization can be carried out in one pot by
hydroboration with 9-BBN in THF, to give a terminally
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147
79
substituted alkyl borane that is then treated with
iodobenzene, KZC03 and catalytic PdClz (dppf) .
t
It is apparent from the above description that no
single general synthesis can be used in the preparation
of all of the novel compounds of this invention, because
some of the radicals, well known to those skilled in the
art, will or may have the potential of interfering with,
competing with or inhibiting the some of the reactions
involved in the pathway. However, one skilled in the
art is fully aware of appropriate point in the synthetic
pathway when a radical may be introduced and when
protecting groups can be used.
Sulfonyl halides can be prepared by the reaction of
a suitable alkyl, aryl, heteroaryl, heterocyclyl and the
like Grignard or lithium reagents with sulfuryl
chloride, or sulfur dioxide followed by oxidation with a
halogen, preferably chlorine. Alkyl, heteroaryl,
heterocyclyl, aryl and the like Grignard or lithium
reagents can be prepared from their corresponding halide
(such as chloro or bromo) compounds which are
commercially available or readily prepared from
commercially available starting materials using known
methods in the art. Alternatively, mercaptans may be
oxidized to sulfonyl chlorides using chlorine in the
presence of water under carefully controlled conditions.
Additionally, sulfonic acids may be converted into
sulfonyl halides using reagents such as PC15, SOC12,
C1C(O)C(O)C1 and the like, and also to anhydrides using
suitable dehydrating reagents. The sulfonic acids are
either commercially available or may be prepared using
procedures well known in the art from commercially
available starting materials. In place of the sulfonyl
halides, sulfinyl halides or sulfenyl halides can be
utilized to prepare compounds wherein the sulfonyl
moiety is replaced by an sulfinyl or thio moiety,
respectively. Arylsulfonic acids, benzo fused
heterocyclyl sulfonic acids or heteroaryl sulfonic acids
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147
can be prepared by sulfonation of the aromatic ring by
well known methods in the art, such as by reaction with
sulfuric acid, 503, S03 complexes, such as DMF(S03),
pyridine(S03), N,N-dimethylacetamide(S03), and the like.
5 Preferably, such sulfonyl halides are prepared from such
aromatic compounds by reaction with DMF(S03) and SOC12 or
C1C(O)C(O)Cl. The reactions may be performed stepwise
or in a single pot.
Alkyl sulfonic acids, aryl sulfonic acids,
10 heterocyclyl sulfonic acids, heteroaryl sulfonic acids,
alkylmercaptans, arylmercaptans, heterocyclylmercaptans,
heteroarylmercaptans, alkylhalides, arylhalides,
heterocyclylhalides, heteroarylhalides, and the like are
commercially available or can be readily prepared from
15 starting materials commercially available using standard
methods well known in the art.
Thioether derivatives can be converted into the
corresponding sulfone or sulfoxide by oxidizing the
thioether derivative with a suitable oxidation agent in
20 a suitable solvent. Suitable oxidation agents include,
for example, hydrogen peroxide, sodium meta-perborate,
oxone (potassium peroxy monosulfate), meta-
chloroperoxybenzoic acid, periodic acid and the like,
including mixtures thereof. Suitable solvents include
25 acetic acid (for sodium meta-perborate) and, for other
peracids, ethers such as THF and dioxane, and
acetonitrile, DMF and the like, including mixtures
thereof .
The chemical reactions described above are
30 generally disclosed in terms of their broadest
application to the preparation of the compounds of this
invention. Occasionally, the reactions may not be
applicable as described to each compound included within
the disclosed scope. The compounds for which this
35 occurs will be readily recognized by those skilled in
the art. In all such cases, either the reactions can be
successfully performed by conventional modifications

protection of interfering groups, by changing to
alternative conventional reagents, by routine
modification of reaction conditions, and the like, or
other reactions disclosed herein or otherwise
conventional, will be applicable to the preparation of
the corresponding compounds of this invention. In all
preparative methods, all starting materials are known or
readily prepared from known starting materials.
Prodrugs of the compounds of this invention are
also contemplated by this invention. A prodrug is an
active or inactive compound that is modified chemically
through in vivo physicological action, such as
hydrolysis, metabolism and the like, into a compound of
this invention following adminstration of the prodrug to
a patient. The suitability and techniques involved in
making and using prodrugs are well known by those
skilled in the art. For a general discussion of
prodrugs involving esters see Svensson and Tunek Drug
Metabolism Reviews 165 (1988) and Bundgaard Design of
Prodrugs, Elsevier (1985). Examples of a masked
carboxylate anion include a variety of esters, such as
alkyl (for example, methyl, ethyl), cycloalkyl (far
example, cyclohexyl), aralkyl (for example, benzyl, p-
methoxybenzyl), and alkylcarbonyloxyalkyl (for example,
pivaloyloxymethyl). Amines have been masked as
arylcarbonyloxymethyl substituted derivatives which are
cleaved by esterases in vivo releasing the free drug and
formaldehyde (Bungaard J. Med. Chem. 2503 (1989)).
Also, drugs containing an acidic NH group, such as
imidazole, imide, indole and the like, have been masked
with N-acyloxymethyl groups (Bundgaard Design of
Prodrugs, Elsevier {1985)). Hydroxy groups have been
masked as esters and ethers. EP 039,051 (Sloan and
Little, 4/11/81) discloses Mannich-base hydroxamic acid
prodrugs, their preparation and use.

To a stirred solution of thiophene-2-carboxaldehyde
(44.48, 0.39mo1) in absolute ethanol (80.Om1, 4.9M) was
added glycine (14.8g, 0.20mo1) at ambient temperature.
The resulting suspension was cooled to OoC, at which
5 time a solution of potassium hydroxide (22.2g, 0.39mo1)
in absolute ethanol (120.0, 3.3M) was introduced in a
dropwise manner. Upon complete addition, the reaction
mixture was kept at -10°C for ninety minutes. The
yellow solid which had precipitated during this time was
10 collected via filtration and washed with ethanol. The
solid was dissolved into water (70.Om1) and treated with
glacial acetic acid (l5.Om1). The resulting solution
was stored at -10°C for eighteen hours. The
precipitated product was collected via filtration to

formaldehyde (45.0m1) at ambient temperature. The
resulting mixture was stirred for three days after which
time the product precipitated from solution. The solid
was collected via filtration and washed with water

To a solution of tributylphenyl tin (1.1 g, 3.0 mmole)
in THF at -78°C was dropwise added nBuLi (2M, 1.5 mL,
3.0 mmole). The reaction mixture was then stirred at
that temperature for 10 min, followed by an addition of
ZnCl2 (0.5M, 6.0 mL, 3.0 mmole}. The reaction mixture
was then allowed to slowly warm up to 25°C and was
stirred at that temperature for another 10 min. The
above Zn-reagent was then added into a mixture of cis-2-
iodo-7-hydroxy-5-(4-methoxyphenylsulfonyl)-4,5,6,7-
tetrahydrothieno[3,2-c]pyridine-6-carboxylic acid (495

Example 73
The following assays are in vitro assays which were
used to characterize the ability of compounds of this
invention to inhibit the production of TNF-a by
monocytes following LPS stimulation, Human Monocyte TNF
Convertase Assay, Human Neutrophil Collagenase Assay and
Human Fibroblast Stromelysin Assay.
Lipopolysaccharide-activated monocyte TNF production
assay
Isolation of monocvtes
Test compounds were evaluated in vitro for the
ability to inhibit the production of tumor necrosis
factor (TNF) by monocytes activated with bacterial
lipopolysaccharide (LPS). Fresh residual source
leukocytes (a byproduct of plateletpheresis) were
obtained from the local blood bank and peripheral blood
mononuclear cells (PBMCs) were isolated by density
gradient centrifugation on Ficol-Paque Plus (Pharmacia).
PBMCs were suspended at 2 x 106/ml in DMEM supplemented
to contain 2o FCS (10 mM), 0.3 mg/ml glutamate, 100 U/ml
penicillin G and 100 mg/ml streptomycin sulfate
(complete media). Cells were plated into Falcon
flatbottom 96 well culture plates (200 ul/well) and
cultured overnight at 37oC and 6~ C02. Nonadherent
cells were removed by washing with 200 ul/well of fresh
medium. Wells containing adherent cells (~70~
monocytes) were replenished with 100 ul of fresh medium.
Preparation of test compound stock solutions
Test compounds were dissolved in DMS. Compound
stock solutions were prepared to an initial
concentration of 10 - 50 ~,iM. Stocks were diluted
initially to 20 - 200 ~.iM in complete media. Nine two-
fold serial dilutions of each compound were then
prepared in complete medium.

Treatmentof cells with test compounds and activation of
TNF production with lipopolysaccharide
One hundred microliters of each test compound
dilution were added to microtiter wells containing
adherent monocytes and 100 ul complete medium.
Monocytes were cultured with test compounds for 60 min
at which time 25 ul of complete medium containing 30
ng/ml lipopolysaccharide from E. coli K532 were added to
each well. Cells were cultured an additional 4 hrs.
Culture supernatants were then removed and TNF present
in the supernatants was quantified using an ELISA.
TNF ELISA
Flat bottom 96 well Corning High Binding ELISA
plates were coated overnight (4oC) with 250 uL/well of 3
ug/ml murine ant i human TNFa MAb (R&D Systems #MAB210).
Wells were then blocked 1 h at room temperature with 200
uL/well of CaCl2-free ELISA buffer supplemented to
contain 20 mg/ml BSA (standard ELISA buffer: 20 mM, 150
mM NaCl, 2 mM CaCl2, 0.15 mM thimerosal, pH 7.4).
Plates were washed and replenished with 100 ul of test
supernatants (diluted 1:3) or standards. Standards
consisted of eleven 1.5-fold serial dilutions from a
stock of 1 ng/ml recombinant human TNF (R&D Systems).
Plates were incubated at room temperature for 1 h on
orbital shaker (300 rpm), washed and replenished with
100 ul/well of 0.5 ug/ml goat anti-human TNFa (R&D
systems #AB-210-NA) biotinylated at a 4:1 ratio. Plates
were incubate for 40 min, washed and replenished with
100 ul/well of alkaline phosphatase-conjugated
streptavidin (Jackson ImmunoResearch #016-050-084) at
0.02 pg/ml. Plates were incubated 30 min, washed and
replenished with 200 ul/well of 1 mg/ml of p-nitrophenyl
phosphate. After 30 min, plates were read at 405 nm on
a Vmax plate reader.

Data analysis
Standard curve data were fit to a second order
polynomial and unknown TNFa concentrations determined
from their OD by solving this equation for
concentration. TNF concentrations were then plotted vs.
test compound concentration using a second order
polynomial. This equation was then used to calculate
the concentration of test compounds causing a 50~
reduction in TNF production.
Human Monocyte TNF Convertase Assay
TNF convertase activity is demonstrated by
hydrolytic cleavage of a dinitrophenyl (DNP)-labeled
peptide substrate between amino acids Ala and Val.
Dependent on the purity of the TNF convertase used in
the reaction, hydrolysis of incorrectly clipped DNP-
peptides are also possible. Human monocyte TNF
convertase activity is determined by using DNP-labeled
peptide substrate (1) Dnp-SPLAQAVRSSSR-CONH2; and
clipped peptides: (2) DNP-SPLAQ-COON (incorrectly
clipped between Gln and Ala); (3) DNP-SPLAQA-COON
(correctly clipped); and (4) DNP-SPLAQAV-COOH
(incorrectly clipped between Val and Arg).
Full length and clipped DNP-peptides are separated
and quantitated using reversed phase HPLC, monitoring at
350 nM (where dinitrophenyl absorbs). Inhibitors of TNF
convertase in the reaction are detected by a decrease in
peak height of peptide 3 and an increase in peak height
of peptide 1. Inhibition is calculated as percent of
control by comparing peak height of peptide 3 in samples
with no inhibitors (control conditions) and peak height
of peptide no. 3 in samples with inhibitors.
Typically, compounds at 2 mM in DMSO are first
diluted 1:11.8 in 40 mM Tris, pH 7.5. A further 1:17
dilution of the compound occurs in the final reaction
mixture. This reaction mixture contains 2.5~L of the
CA 02297988 2000-O1-25
WO 99/06410 PCT/IJS98/16147
248
diluted compound, 20 ~.L of peptide 1, and 20 ~,L of TNF
convertase. This results in a compound concentration of
~.tM, 0.5~ DMSO, in the final reaction volume. Compounds
are initially screened at 10 uM and selected compounds are
5 further assayed to determine an ICSO~
Human Neutrophil Collagenase Assay
Human neutrophil collagenase (HNC) activity is
determined by using fluorogenic peptide substrate Dnp-
10 Pro-b-Cyclohexyl-Ala-Gly-Cys(Me)-His-Ala-Lys-(N-
methylanthranilic acid)-NHz. The N-terminus Dnp group
and the C-terminus N-methyl-anthranilyl moiety (Nma) are
fluorescence self-quenching until the peptide is cleaved
at the Gly-Cys(me) bond. The fluorescence from the
cleavage products is measured on a Bio-Tek Instrument
FL500 fluorescence micro-plate reader (excitation at 360
nm, emission at 460 nm). The assay is performed in a
96-well plate (in duplicate), and the Km = 51 nM for the
substrate, and Ki = 722 nM for Actinonin have been
determined. The test compounds (at 100, 33 & 10 mM) are
compared for their inhibition of HNC activity on the
substrate against the activity of Actinonin and Ki's
were determined on selected compounds.
Human Fibroblast Stromelysin Assay
Human fibroblast stromelysin (HFS) activity is
determined by using fluorogenic peptide substrate Dnp-
Pro-b-Cyclohexyl-Ala-Gly-Cys(Me)-His-Ala-Lys-(N-
methylanthranilic acid)-NH2. The N-terminus Dnp group
and the C-terminus N-methyl-anthranilyl moiety (Nma) are
fluorescence self-quenching until the peptide is cleaved
at the Gly-Cys(me) bond. The fluorescence from the
cleavage products is measured on a Bio-Tek Instrument
FL500 fluorescence micro-plate reader (excitation at 360
nm, emission at 460 nm). The assay is performed in a
96-well plate (in duplicate), and the Km = 51 nM for the
substrate, and Ki = 722 nM for Actinonin (an inhibitor

of enzyme activity; Sigma Chemical, St. Louis, MO;
A6671) have been determined as the standard control.
The test compounds (at 100, 33 & 10 mM) are compared for
their inhibition of HFS activity on the substrate
against the activity of Actinonin and Ki's were
determined on selected compounds.
Inhibition of LPS-Induced TNF-a production in mice
Male DBA/1LACJ mice were dosed with vehicle or test
compounds in a vehicle (the vehicle consisting of 0.5~
tragacanth in 0.03 N HC1) prior to lipopolysaccharide (2
mg/kg, I.V.) injection. Ninety minutes after LPS
injection, blood was collected and the serum was
analyzed by ELISA for TNF levels.

Pharmaceutical Compositions
This invention further relates to the use of a
compound of this invention in the manufacture of a
medicament for the prophylaxis and treatment, either
acutely or chronically, of TNF-a mediated disease
states. In addition, the compounds of this invention
are useful in the manufacture of a medicament for
treating disease states in which HNC and/or HFS play a
role.
This invention also relates to a pharmaceutical
composition comprising a compound of this invention and
a pharmaceutically acceptable carrier, and if desired
other active ingredients. The compounds of this
invention are administered by any suitable route,
preferably in the form of a pharmaceutical composition
adapted to such a route, and in a dose effective for the
treatment intended. Therapeutically effective doses of
the compounds of the present invention required to
arrest the progress or prevent tissue damage associated
with the disease are readily ascertained by one of
ordinary skill in the art.
For the prophylaxis and treatment of disease
states, the compounds of the present invention may be
administered orally, parentally, or by inhalation spray,
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147
256
rectally, or topically in dosage unit formulations
containing conventional pharmaceutically acceptable
carriers, adjuvants and vehicles. The term parenteral
as used herein includes, subcutaneous, intravenous,
intramuscular, intrasternal, infusion techniques or
intraperitoneally.
The amount of active ingredient that may be
combined with the carrier materials to produce a single
dosage form will vary depending upon the host treated
and the particular mode of administration.
The dosage regimen for treating a disease state
with the compounds of this invention and/or compositions
of this invention is based on a variety of factors,
including the type of disease, the age, weight, sex and
medical condition of the patient, the severity of the
condition, the route of administration, pharmacological
considerations such as the activity, efficacy,
pharmacokinetic and toxicology profiles of the
particular compound employed, whether a drug delivery
system is utilized and whether the compound is
administered as part of a drug combination. Thus the
dosage regimen may vary widely. Dosage levels of the
order from about 0.01 mg to 80 mg per kilogram of body
weight per day, preferably from about 0.5 mg to 30
mg/kg, more preferably from about 1 mg to 15 mg/kg are
useful for all methods of use disclosed herein. The
pharmaceutically active compounds of this invention can
be processed in accordance with convential methods of
pharmacy to produce medicinal agents for administration
to patients, mammals including humans.
For oral administration, the pharmaceutical
composition may be in the form of, for example, a
capsule, a tablet, a suspension, or liquid. The
pharmaceutical composition is preferably made in the
form of a dosage unit containing a given amount of the
active ingredient. For example, these may contain an
amount of active ingredient from about 1 to 250 mg,
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147
257
preferably from about 25 to 150 mg. A suitable daily
dose for a human or other mammal may vary widely
depending on the condition of the patient and other
f actors .
The compounds of this invention may also be
administered by injection as a composition with suitable
carriers including saline, dextrose, or water. The
daily parenteral dosage regimen wll be from about 0.1 to
about 80 mg/kg of total body weight, preferably from
about 0.5 to about 30 mg/kg, and more preferably from
about 1 mg to 15 mg/kg.
Injectable preparations, for example, sterile
injectable aqueous or oleaginous suspensions may be
formulated according to the known art using suitable
dispersing or wetting agents and suspending agents. The
sterile injectable preparation may also be a sterile
injectable solution or suspension in a nontoxic
parenterally acceptable diluent or solvent, for example,
as a solution in 1,3-butanediol. Among the acceptable
vehicles and solvents that may be employed are water,
Ringer's solution, and isotonic sodium chloride
solution. In addition, sterile, fixed oils are
conventionally employed as a solvent or suspending
medium. For this purpose any bland fixed oil may be
employed including synthetic mono- or diglycerides. In
addition, fatty acids such as oleic acid find use in the
preparation of injectables.
Suppositories for rectal administration of the drug
can be prepared by mixing the drug with a suitable
nonirritating excipient such as cocoa butter and
polyethylene glycols which are solid at ordinary
temperatures but liquid at the rectal temperature and
will therefore melt in the rectum and release the drug.
A suitable topical dose of compounds of this
invention is 0.1 mg to 150 mg administered one to four,
preferably two or three times daily. For topical
administration, the active ingredient may comprise from
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147
258
0.001 to 10~ w/w, e.g. from 1~ to 2~ by weight of the
formulation, although it may comprise as much as 10~
w/w, but preferably not more than 5~ w/w, and more
preferably from 0.1~ to 1~ of the formulation.
Formulations suitable for topical administration include
liquid or semi-liquid peparations suitable for
penetration through the skin such as liniments, lotions,
ointments, creams, or pastes and drops suitable for
administration to the eye, ear, or nose.
For administration, the compounds of this invention
are ordinarily combined with one or more adjuvants
appropriate for the indicated route of administration.
The compounds may be admixed with lactose, sucrose,
starch powder, cellulose esters of alkanoic acids,
stearic acid, talc, magnesium stearate, sodium,
magnesium oxide, sodium and calcium salts of phosphoric
and sulphuric acids, acacia, gelatin, sodium alginate,
polyvinylpyrrolidine, and/or polyvinyl alcohol, and
tableted or encapsulated for conventional
administration. Alternatively, the compounds of this
invention may be dissolved in saline, water,
polyethylene glycol, propylene glycol, ethanol, corn
oil, peanut oil, cottonseed oil, sesame oil, benzyl
alcohol, and/or various buffers. Other adjuvants and
modes of administration are well known in the
pharmaceutical art. The carrier or diluent may include
time delay material, such as glyceryl monostearate or
glyceryl distearate alone or with a wax, or other
materials well known in the art.
The pharmaceutical compositions may be made up in a
solid form including granules, powders or suppositories
or in a liquid form such as solutions, suspensions, or
emulsions. The pharmaceutical compositions may be
subjected to conventional pharmaceutical operations such
as sterilization and/or may contain conventional
adjuvants, such as preservatives, stabilizers, wetting
agents, emulsifiers, buffers, etc.

Solid dosage forms for oral administration may
include capsules, tablets, pills, powders, and granules.
In such solid dosage forms, the active compound may be
admixed with at least one inert diluent such as sucrose
lactose or starch. Such dosage forms may also comprise,
as in normal practice, additional substances other than
inert diluents, e.g., lubricating agents such as
magnesium stearate. In the case of capsules, tablets,
and pills, the dosage forms may also comprise buffering
agents. Tablets and pills can additionally be prepared
with enteric coatings.
Liquid dosage forms for oral administration may
include pharmaceutically acceptable emulsions,
solutions, suspensions, syrups, and elixirs containing
inert diluents commonly used in the art, such as water.
Such compositions may also comprise adjuvants, such as
wetting agents, emulsifying and suspending agents, and
sweetening, flavoring, and perfuming agents.
Compounds of the present invention can possess one
or more asymmetric carbon atoms and are thus capable of
existing in the form of optical isomers as well as in
the form of racemic or nonracemic mixtures thereof. The
optical isomers can be obtained by resolution of the
racemic mixtures according to conventional processes,
for example by formation of diastereoisomeric salts by
treatment with an optically active acid or base.
Examples of appropriate acids are tartaric,
diacetyltartaric, dibenzoyltartaric, ditoluoyltartaric
and camphorsulfonic acid and then separation of the
mixture of diastereoisomers by crystallization followed
by liberation of the optically active bases from these
salts. A different process for separation of optical
isomers involves the use of a chiral chromatography
column optimally chosen to maximize the separation of
the enantiomers. Still another available method
involves synthesis of covalent diastereoisomeric
molecules by reacting compounds of Formula I with an
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147
260
optically pure acid in an activated form or an optically
pure isocyanate. The synthesized diastereoisomers can
be separated by conventional means such as
chromatography, distillation, crystallization or
sublimation, and then hydrolyzed to deliver the
enantiomerically pure compound. The optically active
compounds of Formula I can likewise be obtained by
utilizing optically active starting materials. These
isomers may be in the form of a free acid, a free base,
an ester or a salt.
The compounds of the present invention can be used
in the farm of salts derived from inorganic or organic
acids. These salts include but are not limited to the
following: acetate, adipate, alginate, citrate,
aspartate, benzoate, benzenesulfonate, bisulfate,
butyrate, camphorate, camphorsulfonate, digluconate,
cyclopentanepropionate, dodecylsulfate, ethanesulfonate,
glucoheptanoate, glycerophosphate, hemisulfate,
heptanoate, hexanoate, fumarate, hydrochloride,
hydrobromide, hydroiodide, 2-hydroxy-ethanesulfonate,
lactate, maleate, methanesulfonate, nicotinate,
2-naphthalenesulfonate, oxalate, palmoate, pectinate,
persulfate, 3-phenylpropionate, picrate, pivalate,
propionate, succinate, tartrate, thiocyanate, tosylate,
mesylate and undecanoate. Also, the basic nitrogen-
containing groups can be quaternized with such agents as
lower alkyl halides, such as methyl, ethyl, propyl, and
butyl chloride, bromides, and iodides; dialkyl sulfates
like dimethyl, diethyl, dibutyl, and diamyl sulfates,
long chain halides such as decyl, lauryl, myristyl and
stearyl chlorides, bromides and iodides, aralkyl halides
like benzyl and phenethyl bromides, and others. Water or
oil-soluble or dispersible products are thereby
obtained.
Examples of acids which may be employed to form
pharmaceutically acceptable acid addition salts include
such inorganic acids as hydrochloric acid, sulphuric
CA 02297988 2000-O1-25
WO 99/06410 PCT/US98/16147
261
acid and phosphoric acid and such organic acids as
oxalic acid, malefic acid, succinic acid and citric acid.
Other examples include salts with alkali metals or
alkaline earth metals, such as sodium, potassium,
calcium or magnesium or with organic bases.
While the compounds of the invention can be
administered as the sole active pharmaceutical agent,
they can also be used in combination with one or more
other agents. When administered as a combination, the
therapeutic agents can be formulated as separate
compositions which are given at the same time or
different times, or the therapeutic agents can be given
as a single composition.

invention and is not intended to limit the invention to
the disclosed compounds. Variations and changes which
are obvious to one skilled in the art are intended to be
within the scope and nature of the invention which are
defined in the appended claims.
From the foregoing description, one skilled in the
art can easily ascertain the essential characteristics
of this invention, and without departing from the spirit
and scope thereof, can make various changes and
modifications of the invention to adapt it to various
usages and conditions.
