Field of the .Tnventiezn
?his invention ie directed generally to the inhibition of the binding of a4~i~
integrin to
its receptors, for example VCAM-1 (vascular cell adhesion molecule-1) and
fibronectin. The
invention also relates to compounds that inhibit this binding;; to
pharmaceutically active
compositions comprising such compounds; and to the use of such compounds
either as above,
IS or in formulations for the control or prevention of disease states in which
a4(3f is involved.
l3ack ound of the lavention
When a tissue has been invaded by a microorganisnx or has been damaged, white
blood cells, also called leukocyte>, play a major role in the inflammatory
response. One of
the most important aspects of the inflammatory response involves the cell
adhesion event.
Generally, ~vhite blood cells are found circulating through the bloodstream.
However, when
a tissue is infected or becomes damaged, the white blood cells recognize ehe
invaded or
damaged tissue, bind to the wall of the capillary and migrate through the
capillary into the
affected tissue. These events are mediated by a family;of proteins called cell
adhesion
molecules.
There are three main type;; of white blood cells; granulocytes, monocytes and
lymphocytes. The intesrin er4~3, (also called VLA-4 for very late antigen-4)
is a heterodimeric
protein expressed on the surface of monocytes, Iyrnphocytes and two subclasses
of
granuiocytes: eosinophils and basophils. This protein plays a key role in cell
adhesion
through its ability to recognize and bind VCAM-1 and fibronectin, proteins
associated with
the endothelial cells that line the interior wall of capillaries.

CA 02366800 2002-O1-07
-2-
Following infection or dat~ilage of tissue surrounding a capillary,
endothelial cells
express a series of adhesion molecules, including YCAIvt-1, that are critical
for bindingthe
white blood cells that are necessary for fighting infection: Prior to binding
to VCAM~ 1 or
.~,,;,
fibronectin, the white blood cells initially bind to certain adhesion
molecules to slow their
flow and allow the cells to "roll" alc>ng the activated endothelium.
Monocytes; lymphocytes,
hasophils and eosinophils are then able to firmly bind to VCA.M-1 or
ftbronectin on the blood
vessel wall via the aapt integrin. There is evidence that such interactions
are also involved in
transmigration of these white blood cells into the damaged tissue as well as
the initial rolling
event itself.
Although white blood cell rGdgration to the site of injury helps fight
infection and
destroy foreign material, in many instances this migration can become
uncontrolled, with
white blood cells flooding to the scene, causing widespread tissue damage.
Compounds
capable of blocking this process, thc;refore, may be beneficial as therapeutic
agents. Thus, it
would be useful to develop inhibito:,rs that would prevent the binding of
white blood cells to
VCAM-l and fibronectin.
Some of the diseases that might be treated by the inhibition of a~Q ~ binding
include,
but are not limited to, atherosclerosis, rheumatoid arthritis, asthma,
allergy, multiple sclerosis,
lupus. inflammatory bowel disease, graft rejection, contact hypersensitivity,
and type I
diabetes. In addition to being found, on some white blood cells, a,~~3~ is
also found on various
cancer cells, including leukemia, melanoma, lymphoma and sarcoma cells, It has
been
suggested that cell adhesion involving a~~3~ rnay be involved i.n the
metastasis of certain
cancers. Inhibitors of a~~3, binding may, therefore, also be useful in the
treatment of some
forms of cancer.
The isolation and purification of a peptide which inhibits the binding of
a4~it to a
protein is disclosed in U.S. Fatent No. 5,510,332. Peptides which inhibit
binding are
disclosed in WO 95/15973, EP 0 341 91 S, EP 0 422 938 A1, t'J.S. Patent No.

cell
adhesion and cell adhesion-mediated pathologies are disclosed in WO 96/22966,

The ring defined by Y in Formulae I, II and ff! can be a mono-cyclic
heterocycle or
aromatic ring, or can be a bicyclic ring.
The dotted lines used in Fornnulae I; B, I>I, N and VI'indicate that the bond
at that
Ioeation can be either single or double. The bond between the atoms Yaxad W
for example
can be a single or double bond if Y and/or W is a substitutent~s,uch as N, C
or CH. Therefore,
l 5 the ring defined by Y in the Formulae can ba either saturated or
unsaturated, depending upon
which W and/or Y is selected. In Formulae N and YT, the dotted line indicates
that the
nitrogen -containing ring optionally contains double bonds at the indicated
locations.
In the Formulas, certain R erour; potentially substitute their associated
rings a
number of times. R~9, R=°, R=~, R~', R'', Ri8 , R=9 and R=$ may each
substitute their
24 associated rings rrzore than once. For example for R~9, when c is zero, the
associated ring is
unsubstituted, having hydrogens at the C-2 and C--4 positions; and for Rz3,
when g is zero,
hydrogens are at the C-2 = C-5 positions.
Suitable substituents for the aryl, alkyl, cycloaikyl, heterocyclyl groups or
the ring defined
by Y and W in the formulae described above, when present, include alcohols,
amines,
25 hetematorns, or any combination of aryl, alkoxy, alkoxyalkoxy, alkyl,

Dosage forms for topical administration of a compound of this invention
include
powders, sprays, ointments and inhalants. The active compound is mixed under
sterile
conditions with a pharmaceutically acceptable carrier aad any needed
preservatives, buffers or
propellants which can be required. Opthalmic formulations, eye ointments,
powders and
solutions are also contemplated as being within the scope of this invention.
Actual dosage levels of active ingredients in the pharmaceutical compositions
of
this invention can be varied so as to obtain an arnount of the active
compound(e) which is
effective to achieve the desired therapeutic response for a, particular
patient, compositions
and mode of administration. The selected dosage level vii depend upon the
activity of
. 10 the particular compound, the route of administration, the severity of the
condition being
treated and the condition aad prioz medical history of the patient being
treated. However,
it is within the stall of the art to start doses of the compound at levels
lower than required
to achieve the desired therapeutic effect and to gradually increase the dosage
until the
desired e~Ct is achieved.
When used in the above or other treatments, a therapeutically effective amount
of
one of the compounds of the present invention can be employed in pure form or,
where
such forms exist, in pharmaceutically acceptable salt, ester or prodrug form.
Alternatively; the compound can be administered as a pharmaceutical
composition
containing the compound of interest in combination with bane or more
pharmaceutically
acceptable excipients. The phrase "therapeutically affective amount" of the
compound of
the invention means a sufficient amount of the compound to treat disorders, at
a
reasonable benefttlrisk ratio applicable to any medical treatment. It will be
understood,
however, that the total daily usage of the compounds and compositions of the
present
invention will be decided by the attending physician within the scope of sound
medical
judgement. The specific therapeutically effective dose level for any
particular patient will
depend upon a variety of faGtOTb including the disorder being treated and the
seventy of
the disorder; activity of the specific compound employed; the specific
composition __
employed; the age, body weight, general health, sex and diet of the patient;
the time of
administration, route of administration, and rate of excretion of the specific
compound
employed; the duration of the treatment; drugs used in combination or
coincidental with
the specific compound employed; and like factors well known in the medical
arts. For

CA 02366800 2002-O1-07
-66-
example, it is well within the skill of the art to start doses of the compound
at levels lower
than required to achieve the desired therapeutic effect and to gradually
increase the
dosage until the desired effect is achieved.
The total daily dos~ of the compounds of this in~'eszi:ion administered to a
human
S or lower animal may range from about 0.0001 to about 1000 mg/kg/day. For
purposes of
oral administration, more preferable doses can be in the range of from about
0.001 to
.Yu°u!
about 5 ms/kg/day. If desired, the effective daily dose can be divided into
multiple doses
for purposes of administration; consequently, single dose compositions may
contain such
amounts or submultiples thereof to make up the daily dose.
The present invention also provides pharmaceutical compositions that comprise
compounds of the present invention formulated together with one ox more non-
toxic
pharmaceutically acceptable carriers. The pharmaceutical compositions can be
speciahy
formulated for oral administration in solid or liquid form, far parenteral
injection or for rectal
administration.
The pharmaceutical compositions of this invention can be administered to
humans
and other mammals orally, rectally, parenterally , intracisternally,
intravaginally,
intraperitoneally, topically (as by powders, ointments or dFOps), bucally or
as an oral or
nasal spray. The terns "parenterally," as used herein, refers to modes of
administration
which include intravenous, intramuseular, intraperitoneal, intrasternal,
subcutaneous and
intraarticular injection and infusion.
Ts another aspect, the pzesent invention provides a pharmaceutical composition
comprising a component of the present invention and a physiologically
tolerable diluent.
The present invention irtcIudes one or more compounds' as described above
formulated
into compositions together with one or more non-toxic physiologically
tolerable or
2S acceptable diluents, carriers, adjuvants or vehicles that are collectively
referred to herein
as diluents, for parenteral injection; for intranasal delivez~i; foz oral
administration in solid
or liquid form, for rectal or topical administration, among others. ,__
The compositions can also be delivered through a catheter for local delivery
at a
target site, via an inttaeoronary scent (a tubular device composed of a fine
wire mesh); or
via a biodegradable polymer. The compounds may also be cornplexed to Iigands,
such as
antibodies, for targeted delivery.

CA 02366800 2002-O1-07
-67-
Compositions suitable for parenteral injection may'comprise physiologically
acceptable, sterile aqueous or nonaqueous solutions, dispersions, suspensions
or
emulsions and sterile powders for reconstitution into sterile injectable
solutions or
dispersions. Examples of suitable aqueous and nonaquecius carriers, diluents,
solvents or
vehicles include water, ethanol, polyols (propyleneglycol, polyethyleneglycol,
glycerol,
and the like); vegetable oils (such as olive oil), injectable organic esters
such as ethyl
oleate, and suitable mixtures thereof.
These compositions can also contain adjuvants such as preserving, wetting,
emulsifying, and dispensing agents. Prevention ~f the action of microorganisms
can be
ensured by various antibacterial and antifungal agents, for example, parabens,
chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to
include
isotonic agents, for example sugars, sodium chloride and the like. Prolonged
absorption
of the injectable pharmaceutical form can be brought about by 'the use of
agents delaying
absorption, for example, aluminum monostearate and gelatin.
Suspensions, in addition to the active compounds, may contain suspending
agents,
as for example, ethoxylated isostearyl alcohols; polyoxyethylene sorbitol and
sorbitan
esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-
agar and
tragacanth, or mixtures of these substances, and the like.
In some cases, in order to prolong the effect of the drug, it is desirable to
slow the
absorption of the drug from subcutaneous or intramuscular injection. This can
be
accomplished by the use of a liquid suspension of crystalline or amorphous
material with
poor water solubility. The rate of absorption of the drug then depends upon
its rate of
dissolution which, in tum, may depend upon crystal size and crystalline form.
Alternatively, delayed absorption of a parenterally administered drug form is
accomplished by dissolving or suspending the drug in an oil vehicle.
injectable depot forms are made by forming microencapsule matrices of the drug
in biodegradable polymers such as polyIactide-polyglycolide. Depending upon
the ratio
of drug to polymer and the nature of the particular polymer employed, the rate
of drug
release can be controlled. Examples of other biodegradable polymers include
poly(orthoesters) and poIy(anhydzides). Depot injectable fbrmulations are also
prepared

CA 02366800 2002-O1-07
-68-
by entrapping the drug in liposomes or microetnulsions which are compatible
with body
tissues.
The injectable formulations can be sterilized, for example, by filtration
through a
bacterial-retaining filter or by iacorpotating sterilizing agents in the form
of sterile solid
compositions which can be dissolved or dispersed in sterile water ar other
sterile
injectable medium just prior to use.
Solid dosage forms for oral administration include capsules, tablets, pills,
powders
and ganules: In such solid dosage forms, the active compound may be mixed with
at
least one inert, pharmaceutically acceptable excipient or carrier, such as
sodium citrate or
dicalcium phosphate andlor a) fillers or extenders such as starches, lactose,
sucrose,
glucose, mannitol and silicic acid; b) binders such as
carboxyrnethylcellulose, alginates,
gelatin, ~lyvinylpyrrolidone, sucrose and acacia; c) humectants such as
glycerol; d)
disinte~aling agents such as agar-agar, calcium carbonate, potato or tapioca
starch,
alginic acid, certain silicates and sodium carbonate; e) solution retarding
agents such as
paraffin; fj absorption accelerators such' as quaternary ammonium compounds;.
g) wetting
agents such as cetyl alcohol and glycerol monostearate; h) absorbents .uch as
kaolin and
bentonite slay and l) lubricants such as talc, calcium stearate, magnesium
stearate, solid
polyethylene glycols, sodium lauryl sulfate and mixtures thereof. In the case
of capsules; .
tablets and pills, the dosage form may also comprise buffering agents.
Solid compositions of a similar type may also be employed as fillers in soft
and
hard-filled gelatin capsules using such excipients as lactose or milk sugar as
well as high
molecular weight polyethylene glycols and the like.
'the solid dosage forms of tablets, dragees, capsules, pills and granules can
be
prepared with coatings and shells such as enteric coatings and other coatirtga
well-known
in the pharmaceutical formulating art. They may optionally contain opacifying
agents and
may also be of s composition such that they release the active ingredients)
only, or
preferentially, -in a certain pact of the intestinal tract, optionally, in a
delayed manner. --
examples of embedding compositions which can be used include polymeric
substances
arid waxes.
The active compounds can also be in micro-encapsulated form, if appropriate,
with one or more of the above-mentioned excipients.

CA 02366800 2002-O1-07
~~ n
Liquid dosage forms for oral administration includ~ pharmaceutically
acceptable
emulsions, solutions, suspensions, syrups and elixirs. In addition to the
active

Example 42
A procedure in which a 26-amino acid peptide containing the CS 1
sequence of fibronectin with an N-terminal Cys
(CDELPQLvTI,plipNLHGPEIt;DVP$T) was coupled to maleimide
activated ovalbumin was used to determine the efficacy of the compounds
synthesized: Bovine serum albumin (BSA) and CS1 conjugated
ovalbumin were coated onto 96-well polystyrene plates at 0.5 ~.g/ml in
TBS (50 mNt TRIS, pH 7.5; I50 mM NaCl) at 4°C for 16 hours. The
IO plates were. washed-thr~e times with TBS and blocked with THS
containing 3°lo BSA at room temperature for 4 hours. Blocked plates
were

-129-
washed three times in binding buffer (TBS; 1 mM MgCla; 1 tnM CaClz; I
mM MnCI~ prior to assay. Ramos cells fluorescently labeled with calcein
AM were resuspended is binding buffer (10' cellsiml) and diluted 1:2
with same buffer with or without compound, I00 p.N! of compound was
added. The cells were added immediately to the wells (2.5 x I OS
cells/well) and incubated for 30 minutes at 37°C. Following three
washes
with-binding buffer, adherent cells were lysed and quantitated using a
fluorome~ter. TI~ results are shown in Tables 2-7. ICso is defined as the
dose required to give 50% inhibition, measatred in ,uM for Tables 2 and 4.
The lower the ICsa value and the greater the pcbrcentage of inhibition, the
more efficient the compound is at preventi~n of cell adhesion.
