4-SUBSTITUTED-QUINOLINE DERIVATIVES AND
4-SUBSTITUTED-QUINOLINE COMBINATORIAL LIBRARIES
BACKGROUND OF 'THE INVENTION
FIELD OF THE INVENTION
The present invention relates ,generally to the synthesis of heterocyclic
compounds based on the 4-substituted quinoline ring. More specifically, the
invention provides novel 4-substituted quinolines as well as novel libraries
comprised
of such compounds.
BACKGROUND I~1FORMATION
The process of discovering ne;w therapeutically active compounds for a
given indication involves the screening of all compounds from available
compound
collections. From the compounds tested ones or more structures) is selected as
a
promising lead. A large number of related analogs are then synthesized in
order to
develop a structure-activity relationship and select one or more optimal
compounds.
With traditional one-at-a-time synthesis and biological testing of analogs,
this
optimization process is long and labor intensive. Adding significant numbers
of new
structures to the compound collections used in the initial screening step of
the
discovery and optimization process cannot be accomplished with traditional
one-at-a-time synthesis methods, except ove~.r a time frame of months or even
years.
2 0 Faster methods are needed that allow for the preparation of up to
thousands of related
compounds in a matter of days or a few weeks. This need is particularly
evident when
it comes to synthesizing more complex compounds, such as 4-substituted
quinolines.
Solid-phase techniques for the synthesis of peptides have been
extensively developed and combinatorial libraries of peptides have been
generated
2 5 with great success. During the past four ye~~rs there has been substantial
development


CA 02279977 1999-08-04
WO 98/34115 PCT/US97/22391
2
of chemically synthesized combinatorial libraries (SCLs) made up of peptides.
The
preparation and use of synthetic peptide combinatorial libraries has been
described,
for example, by Dooley in U.S. Patent 5,367,053, Huebner in U.S. Patent
5,182,366,
Appel et al. in WO PCT 92/09300, Geysen in published European Patent
Application
0 138 855 and Pirrung in U.S. Patent 5,143,854. Such SCLs provide the
efficient
synthesis of an extraordinary number of various peptides in such libraries and
the
rapid screening of the library which identifies lead pharmaceutical peptides.
Combinatorial approaches have recently been extended to "organic," or
non-peptide, libraries. The organic libraries to the present, however, are of
limited
diversity and generally relate to peptidomimetic compounds; in other words,
organic
molecules that retain peptide chain pharmacophore groups similar to those
present in
the corresponding peptide.
Combinatorial chemical methods have been applied to a limited
number of heterocyclic compounds, as described, for example, in U.S. Patent
5,288,514 to Ellman, U.S. Patent 5,324,483 to Cody et al. and Goff and
Zuckermann,
J. Org. Chem., 60:5748-5749 (1995)). Additionally, there is U.S. Patent
5,549,974 to
Holmes and U.S. Patent 5,506,337 to Summerton and Weller. The patent
application
WO 94/08051 discloses the reaction of ether-linked aldehyde-derived imines
with
dihydrofiuan under Lewis acid catalysis. The library, however, was limited to
108
2 0 compounds. However, the heterocyclic libraries to date contain compounds
of limited
diversity and complexity.
Leeson et al., J. Med. Chem., 35:1954 (1992), reported related
tetrahydroquinolines as N-methyl-D-aspartate (NMDA) receptor site antagonists
wherein the 2-position was by necessity a carboxy group, the 4-position an
acylated
2 5 amine and two chlorine atoms present in the aromatic ring. In the one
example
employing N-vinylpyrrolidinone, Leeson et al. were limited to a stepwise
procedure
that required boron trifluoride as condensation agent. Mellor et al.,
Tetrahedron
Le rs 32:7103 (1991}, described the use of 300 mole percent styrenes and


CA 02279977 1999-08-04
WO 98/34115 PCTlUS97/22391
formaldehyde with electron deficient anilines to prepare tetrahydroquinolines
in
modest yield but not free of the uncyclized adduct. This was modestly extended
in
Mellor and Mernman, Tetrahedron, 5 I :6115 ( 1995) but could not be halted at
the
single adduct stage except for electron withdrawn anilines
Substituent limitations have been overcome for mixtures of peptides
and peptidomimetics through the use of sol id phase techniques versus solution-
phase.
An important step in the development of solid-phase techniques was the
discovery of
methods to identify active individual compounds from soluble mixtures of large
numbers of compounds, as described, for e:~ample, by Rutter in U.S. Patent
5,010,175
and Simon in WO PCT 91/19735. These soluble mixture methods, however, have
rarely been applied to the syntheses of complex heterocyclic structures. There
exists a
need to develop more complex "organic" libraries based on heterocyclic
medicinal
compounds which would require less time .and effort in the synthesis and
testing
needed to bring an organic pharmaceutical product to fruition. In short,
improved
methods for generating therapeutically useiizl heterocyclic compounds, such as
-4-
substituted quinoline derivatives, are desired.
This invention satisfies these needs and provides related advantages as
well. The present invention overcomes the known limitations to classical
organic
synthesis of -4-substituted quinolines and as well as the shortcomings of
2 0 combinatorial chemistry with heterocycles,. The present invention combines
the
techniques of solid-phase synthesis of heterocycles and the general techniques
of
synthesis of combinatorial libraries to prepare new 4-substituted quinoline
compounds.

instant
compounds formed by a carboxylic acid and an amino group is referred to by
this
term. For example, a cation for a carboxylate anion will exist when RZ or R3
is
substituted with a (quaternary ammonium)methyl group. A preferred cation for
the
2 0 carboxylate anion is the sodium cation.
The compounds of the above Formulae can also exist as solvates and
hydrates. Thus, these compounds may crystallize with, for example, waters of
hydration, or one, a number of, or any fraction thereof of molecules of the
mother
liquor solvent. The solvates and hydrates of such compounds are included
within the
2 5 scope of this invention.

The term "amino acid" includes any one of the twenty naturally-
occurring amino acids or the D-form of any one of the naturally-occurring
amino
acids. In addition, the term "amino acid" also includes other non-naturally
occurnng
amino acids besides the D-amino acids, which are functional equivalents of the
naturally-occurring amino acids. Such non-naturally-occurnng amino acids
include,
for example, norleucine ("Nle"), norvaline ("Nva"), p-Alanine, L- or D-
naphthalanine,
2 0 ornithine ("Orn"), homoarginine (homoArg;i and others well known in the
peptide art,
such as those described in M. Bodanzsky, "lprinciples of Peptide Synthesis," 1
st and
2nd revised ed., Springer-Verlag, New York, NY, 1984 and 1993, and Stewart and
Young, "Solid Phase Peptide Synthesis," 2n.d ed., Pierce Chemical Co.,
Rockford, IL,
1984, both of which are incorporated herein by reference. Amino acids and
amino
2 5 acid analogs can be purchased commercially (Sigma Chemical Co.; Advanced
Chemtech) or synthesized using methods luiown in the art.
The amino acids are indicated herein by either their full name or by the
commonly known three letter code. Further, in the naming of amino acids, "D-"
designates an amino acid having the "D" configuration, as opposed to the
naturally


CA 02279977 1999-08-04
WO 98/34115 PCT/US97/22391

occurring L-amino acids. Where no specific configuration is indicated, one
skilled in
the art would understand the amino acid to be an L-amino acid. The amino acids
can,
however, also be in racemic mixtures of the D- and L-configuration or the D-
amino
acid can readily be substituted for that in the L-configuration.
As used herein, a chemical or combinatorial "library" is an intentionally
created collection of differing molecules which can be prepared by the
synthetic
means provided below or otherwise and screened for biological activity in a
variety of
formats (e.g., libraries of soluble molecules, libraries of compounds attached
to resin
beads, silica chips or other solid supports). The libraries can be screened in
any
variety of assays, such as those detailed below as well as others useful for
assessing
the biological activity. The libraries are useful in their ability to rapidly
synthesize
and screen a diverse number or compounds. Moreover, the libraries will
generally
have at least one active compound and are generally prepared in such that the
compounds are in equimolar quantities.
"Combinatorial chemistry" or "combinatorial synthesis" refers to the
parallel synthesis of diverse compounds by sequential addition of reagents
which
leads to the generation of large chemical libraries having molecular
diversity.
Combinatorial chemistry, therefore, involves the systematic and repetitive,
covalent
connection of a set of different "building blocks" of varying structures to
yield Iarge
2 0 arrays of diverse molecular entities.
The compounds of Formula I and combinatorial libraries containing
the same can be prepared as set forth in the Reaction Schemes provided in the
Figures
and described below. The substituents R' to R9 in the Reaction Schemes have
the
same meaning as those described above. The substituent Y in the Reaction
Schemes
2 5 is the same as defined above with the exception that it is still bound to
resin or is the
functionalized resin and, therefore, has one less hydrogen.

In brief, the 4-substituted quinoline compounds of the present
invention can be prepared according to Reacvtion Scheme I as shown in Figure
1. As
depicted in Figure 1, a solid support resin-bound aniline ( I ) (resin
identified by a
shaded circle) is reacted, in situ, with an alde:hyde (2) and is thereby,
converted to the
corresponding imine (3). This is performed i:n the presence of a dieneophile
and an
acid. In the presence of the dieneophile, the imine(3) undergoes a hetero-
Diels-Alder-
like reaction and yields the 4-substituted tetr;ahydroquinoline (4).
More specifically, as shown by Reaction Scheme II in Figure 2, the 4-
substituted quinolines and libraries containing the same are prepared by the
following
more detailed steps. First, the anilines, (as shown in Figure 2), are coupled
to resin,
such as MBHA (Figure 2), MBA, Tentagel~'~ and the like as described below,
using a
carbodiimide coupling agent, such as dicyclohexyicarbodiimide, diisopropyl-
carbodiimide, N-dimethylaminoethyl-N'- ethyl-carbodiimide and the like, and an
activator, such as 1-hydroxybenzotriazole, 7-aza-I-hydroxybenzotriazole and
the like,
in an aprotic polar solvent such as dichloromethane, dimethylformamide and the
like,
at between 10 ° C and I 00 ° C, preferably at 2 S ° C,
for 2 to 24 hours, preferably 8 to 16
hours. The protecting group ("PG") of the a-amino group is removed using a
strong
acid such as trifluoroacetic acid or trifluoronnethanesulfonic acid and the
like ( 1-95%)
or using an amine base such as piperidine, pyrrolidine, or morpholine and the
like ( 1-
2 0 95%) in an aprotic solvent such as dichloronnethane, dimethyiformamide and
the like,
at between I 0 ° C and I 00 ° C, preferably at 25 ° C,
for 2 to 24 hours, preferably 8 to 16
hours. The free amino group of the individual or mixtures of resin-bound
anilines is
condensed with an aldehyde in the presence of a dieneophile, such as 4-
methoxystyrene, 3,5-dimethoxystyrene, N-vinylpyrrolidine, N-methyl-N-
2 5 vinylpyrrolidine and the like and an acid, such as trifluoroacetic acid,
toluenesulfonic
acid and the like, using in a polar solvent, such as dichloromethane,
dimethylformamide, dimethylacetamide, N-methylpyrrolidinone or the like, for a
period of 1 to 72 hours, usually 12 to 24 hours at 20 ° C to 75
° C and preferably at
25°C to arrive at novel 4-substituted quinoline derivatives. Finally,
the compounds

art and
the compounds tested for biological activity.
More specifically, as shown by Reaction Scheme III in Figure 3, the 4-
substituted quinolines and libraries containing the same are prepared by the
following
more detailed steps. First, as shown in Figure 3, N-Boc-nitrophenylalanines
or,
alternatively, the FMOC protected analogs are coupled to resin, such as MBHA,
MBA, TentagelT"'' and the like as described below, using a carbodiimide
coupling
agent, such as dicyclohexylcarbodiimide, diisopropyl-carbodiimide,
N-dimethylaminoethyl-N'-ethyl-carbodiimide and the like, and an activator,
such as
1-hydroxybenzotriazole, 7-aza-1-hydroxybenzotriazole and the like, in an
aprotic
polar solvent such as dichloromethane, dimethylformamide and the like, at
between
10 ° C and 100 ° C, preferably at 2S ° C, for 2 to 24
hours, preferably 8 to 16 hours. The
BOC of the a-amino group is removed using a strong acid such as
trifluoroacetic acid
or trifluoromethanesulfonic acid and the like (1-9S%) in an aprotic solvent
such as
dichloromethane, dimethylformamide and the like, at between 10 ° C and
100 ° C,
preferably at 2S°C, for 2 to 24 hours, preferably 8 to 16 hours.
Alternatively, the
FMOC of the a amino acid is removed using an amine base such as piperidine,
pyrrolidine, or morpholine and the like (1-9S%) in an aprotic solvent such as
dichloromethane, dimethylformamide and the like, at between 10 ° C and
100 ° C,
2 0 preferably at 2S °C, for 2 to 24 hours, preferably 8 to 16 hours.
The free amino group

like (Figure
3), using a carbodiimide coupling agent, such as dicyclohexylcarbodiimide,
diisopropyl-carbodiimide, N-dimethylaminoethyl-N'-ethyl-carbodiimide and the
like,
and an activator, such as 1-hydroxybenzotriazole, 7-aza-1-hydroxybenzotriazole
and
2 5 the like, in an aprotic polar solvent such as dichloromethane,
dimethylformamide and
the like, at between 10 ° C and 100 ° C, preferably at 2S
° C, for 2 to 24 hours, preferably
8 to 16 hours. The nitro group of the phenylalanine is subj ected to
conditions to
reduce the nitro group to an amine, in the case of Reaction Scheme III tin
dichloride,
in an aprotic solvent such as chloroform, dimethylformamide,
dimethylacetamide,
3 0 N-methylpyrrolidinone for 2 to 36 hours and preferably 16 hours at 20
° C to 12S ° C,

acid or
toluenesulfonic acid and the like, using in a polar solvent, such as
dichloromethane,
dimethylformamide, dimethylacetamide, N-rnethylpyrrolidinone or the like, for
a
period of 1 to 72 hours, usually 12 to 24 hours at 20 ° C to 75
° C and preferably at
25 °C to arrive at novel 4-substituted quinoline derivatives. Finally,
the compounds
can be cleaved from the resin by the methods common to those skilled in the
art and
the compounds tested for biological activity. It should be appreciated by
those of skill
in the art that with certain resins, cleavage from the resin results in the
functional
group on the resin coming off the resin and being maintained with the cleaved
compounds. For example, with an amino-resin, such as methylbenzhydrylamine
resin,
the amine group from the resin is cleaved ofiF the resin and makes the 4-
substituted
quinoline(s) of interest an amide.
The term "functionalized resin" means any resin where functional
groups have been introduced into the resin, as is common in the art. Such
resins
include, for example, those functionalized with amino, amide, or hydroxy
groups.
Such resins which can serve as solid supports are well known in the art and
include,
2 0 for example, 4-methylbenzhydrylamine-copoly(styrene-1 % divinylbenzene)
(MBHA),
4-hydroxymethylphenoxymethyl-copoly(styrene-I% divinylbenzene),
4-oxymethyl-phenyl-acetamido-copoly(styrE:ne-1 % divinylbenzene)(Wang), 4-
(oxymethyl)-phenylacetamido methyl (Pam), Tentagel~''', from Rapp Polymere
Gmbh,
and trialkoxy-diphenyl-methyl ester- copoly(styrene-I% divinylbenzene) (RINK)
all
2 5 of which are commercially available. Preparation of the combinatorial
libraries can be
by the "split resin approach." The split resin approach is described by, for
example,

The 4-substituted quinolines of Formula II, before cleavage from the
resin, can be substituted at positions R9 following Reaction Scheme IV
provided in
Figure 4. Briefly, as shown in Reaction Scheme IV, the 4-substituted quinoline
prepared by the above Reaction Schemes I, II or III is condensed with a
carboxylic
acid, carboxylic acid anhydride, acid halide, alkyl halide or isocyanate in an
aprotic
solvent, such as dimethylformamide, dichloromethane, 1-methyl-2-
pyrrolidinone, N-

of an
acid acceptor, if desired, to furnish the substituted 4-substituted quinoline.
For example, preparation of the library containing alternatively
substituted 4-substituted quinolines other than R9 equal to a hydrogen atom
involves,
instead of cleaving from the resin, free NH of the newly formed 4-substituted
quinoline compound being reacted with a carboxylic acid activated with

allowed to
proceed for 1 to 24 hours at 20 ° C to 80 ° C, preferably at 25

Moreover,
to evaluate whether the subject 4-substituted quinolines have antimicrobial
activity,
and, therefore, can be used to treat infections, the ability of the compounds
to inhibit
bacterial growth can be determined by metl~iods well known in the art. An
exemplary
in vitro antimicrobial activity assay is described in Blondelle and Houghten,
Biochemistry 30:4671-4678 (1991), which is incorporated herein by reference.
In
brief, Staphylococcus aureus ATCC 29213 (Rockville, MD) is grown overnight at
37°C in Mueller-Hinton broth, then re-inoculated and incubated at
37°C to reach the
exponential phase of bacterial growth (i.e., a final bacterial suspension
containing l Os
to 5 x l Os colony-forming units/ml). The concentration of cells is
established by
plating 100 ~l of the culture solution using serial dilutions (e.g., 10-z, 10-
3 and 10'x)
onto solid agar plates. In 96-well tissue culture plates 4-substituted
quinolines,
individual or in mixtures, are added to the bacterial suspension at
concentrations
derived from serial two-fold dilutions ranging from 1500 to 2.9 ~g/ml. The
plates are
incubated overnight at 3 7 ° C and the growth determined at each
concentration by
ODbzo nm. The ICso (the concentration necessary to inhibit 50% of the growth
of the
bacteria) can then be calculated.
Additional assays can be used to test the biological activity of the
instant 4-substituted quinolines. Such as a competitive enzyme-linked
2 0 immunoabsorbent assay and radio-receptor assays, both as described in
greater detail
below. The latter test, the radio-receptor assay, can be selective for either
the ~, 8 or x
opiate receptors and is therefore an indication of 4-substituted quinolines'
analgesic
properties.
Competitive Enzyme-Linked Immunosorbent Assay (ELISA): The
2 5 competitive ELISA method which can be used here is a modification of the
direct
ELISA technique described previously in Appel et al., J. Immunol. 144:976-983
( 1990), which is incorporated herein by reference. It differs only in the MAb
addition
step. Briefly, mufti-well microplates are coated with the antigenic peptide
(Ac-
GASPYPNLSNQQT-NHz) at a concentration of 100 pmol/50 ~ 1. After blocking, 25

wl of a 1.0 mg/ml solution of each 4-substituted quinoline mixture of a
synthetic
combinatorial library (or individual 4-substituted quinoline) is added,
followed by
MAb 125-l OF3 (Appel et al., supra) (25 ~l per well). The MAb is added at a
fixed
dilution in which the 4-substituted quinoline in solution effectively competes
for MAb
binding with the antigenic peptide adsorbed to the plate. The remaining steps
are the
same as for direct ELISA. The concentration of 4-substituted quinoline
necessary to
inhibit 50% of the MAb binding to the control peptide on the plate
(ICS°) is
determined by serial dilutions of the 4-substituted quinoline.
Radio-Receptor Assay: Particulate membranes can be prepared using a
modification of the method described in Pasternak et al., Mol. Pharmacol.
11:340-351
( 1975), which is incorporated herein by reference. Rat brains frozen in
liquid nitrogen
can be obtained from Rockland (Gilbertsville, PA). The brains are thawed, the
cerebella removed and the remaining tissue weighed. Each brain is individually
homogenized in 40 ml Tris-HCl buffer (50 mM, pH 7.4, 4°C) and
centrifuged
(Sorvall~ RCSC SA-600: Du Pont, Wilmington, DE) (16,000 rpm) for 10 mins. The
pellets are resuspended in fresh Tris-HCl buffer and incubated at 37°C
for 40 mins.
Following incubation, the suspensions are centrifuged as before, the resulting
pellets
resuspended in 100 volumes of Tris buffer and the suspensions combined.
Membrane
suspensions are prepared and used in the same day. Protein content of the
crude
2 0 homogenates generally range from 0.15-0.2 mg/ml as determined using the
method
described in M.M. Bradford, M.M., Anal. Biochem. 72:248-254 (1976), which is
incorporated herein by reference.
Binding assays are carried out in polypropylene tubes, each tube
containing 0.5 ml of membrane suspension. 8 nM of 3H-[D-Ala2,Me-Phe4,Gly-

Assay
tubes are incubated for 60 mins. at 25 ° C. The reaction is terminated

subsequently washed with 6 ml of Tris-HCl buffer, 4 ° C. Bound
radioactivity is
counted on a Pharmacia Biotech Betaplate Liquid Scintillation Counter
(Piscataway,
N~ and expressed in cpm. To determine inter- and intra-assay variation,
standard
5 curves in which 3H-DAMGO is incubated in the presence of a range of
concentrations
of unlabeled DAMGO (0.13-3900 nM) are l;enerally included in each plate of
each
assay (a 96-well format). Competitive inhibition assays are performed as above
using
serial dilutions of the 4-substituted quinolines, individually or in mixtures.
ICso
values (the concentration necessary to inhibit 50% of 3H-DAMGO binding) are
then
calculated. As opposed to this q receptor se;iective assay, assays selective
for b
receptors can be carried out using [3H]-Naltrindole (3 nM, specific activity

dosage levels of from 0.7 to 7000 mg per day, and preferably 1 to S00 mg per
day, for
a normal human adult of approximately 70 kg of body weight, this translates
into a
dosage of from 0.01 to 100 mg/kg of body 'weight per day. The specific dosages
2 0 employed, however, can be varied depending upon the requirements of the
patient, the
severity of the condition being treated, and the activity of the compound
being
employed. The determination of optimum dosages for a particular situation is
within
the skill of the art.
For preparing pharmaceutical compositions containing compounds of
2 5 the invention, inert, pharmaceutically acceptable carriers are used. The
pharmaceutical carrier can be either solid or liquid. Solid form preparations
include,
for example, powders, tablets, dispersible granules, capsules, cachets, and
suppositories.


CA 02279977 1999-08-04
WO 98/34115 PCT/LTS97/22391
58 _
A solid carrier can be one or more substances which can also act as
diluents, flavoring agents, solubilizers, lubricants, suspending agents,
binders, or
tablet disintegrating agents; it can also be an encapsulating material.
In powders, the Garner is generally a finely divided solid which is in a
mixture with the finely divided active component. In tablets, the active
compound is
mixed with the carrier having the necessary binding properties in suitable
proportions
and compacted in the shape and size desired.
For preparing pharmaceutical composition in the form of suppositories,
a low-melting wax such as a mixture of fatty acid glycerides and cocoa butter
is first
melted and the active ingredient is dispersed therein by, for example,
stirnng. The
molten homogeneous mixture is then poured into convenient-sized molds and
allowed
to cool and solidify.
Powders and tablets preferably contain between about 5% to about
70% by weight of the active ingredient. Suitable carriers include, for
example,
magnesium carbonate, magnesium stearate, talc, lactose, sugar, pectin,
dextrin, starch,
tragacanth, methyl cellulose, sodium carboxymethyl cellulose, a low-melting
wax,
cocoa butter and the like.
The pharmaceutical compositions can include the formulation of the
active compound with encapsulating material as a carrier providing a capsule
in which
2 0 the active component (with or without other carriers) is surrounded by a
carrier, which
is thus in association with it. In a similar manner, cachets are also
included.
Tablets, powders, cachets, and capsules can be used as solid dosage
forms suitable for oral administration.
Liquid pharmaceutical compositions include, for example, solutions
2 5 suitable for oral or parenteral administration, or suspensions, and
emulsions suitable


CA 02279977 1999-08-04
WO 98/34115 PCT/US97/22391
59 _
for oral administration. Sterile water solutions of the active component or
sterile
solutions of the active component in solvents comprising water, ethanol, or
propylene
glycol are examples of liquid compositions suitable for parenteral
administration.
Sterile solutions can be prepared by dissolving the active component in
the desired solvent system, and then passing the resulting solution through a
membrane filter to sterilize it or, alternatively, by dissolving the sterile
compound in a
previously sterilized solvent under sterile conditions.
Aqueous solutions for oral administration can be prepared by
dissolving the active compound in water and adding suitable flavorants,
coloring
agents, stabilizers, and thickening agents as desired. Aqueous suspensions for
oral
use can be made by dispersing the finely divided active component in water
together
with a viscous material such as natural or synthetic gums, resins, methyl
cellulose,
sodium carboxymethyl cellulose, and other suspending agents known to the
pharmaceutical formulation art.
Preferably, the pharmaceutical composition is in unit dosage form. In
such form, the composition is divided into unit doses containing appropriate
quantities
of the active 4-substituted quinoline. The writ dosage form can be a packaged
preparation, the package containing discrete quantities of the preparation,
for example,
packeted tablets, capsules, and powders in vials or ampules. The unit dosage
form
2 0 can also be a capsule, cachet, or tablet itself., or it can be the
appropriate number of
any of these packaged forms.
The following Examples are intended to illustrate but not limit the
present invention.

EXAMPLE 1
Combinatorial Library Of 4-(4-Methoxyphenyl)Tetrahydroqainoline Derivatives
This Example provides a representative solid-phase combinatorial
synthesis of a library which contains approximately 2380 derivatives of 4-
5 aryltetrahydroquinolines (THQs).
Following the above Reaction Scheme I, preparation of a library
containing the THQs involves the following steps. Briefly, first, 17 diverse
aminobenzoic acids, varying at position of Y-R', R2, R3 or R4 without use of
amino-
protecting groups, were coupled to MBHA resin employing the tea-bag method of
10 Houghten et. al, as described, for example in U.S. Patent No. 4,631,211 to
Houghten
and Houghten et al., Proc. Natl. Acad. Sci., 82:5131-5135 (1985), both of
which are
incorporated herein by reference. After coupling and thorough washing the 17
tea-
bags, each containing one resin-bound aminobenzoic acid, were opened and the
resin
beads combined and thoroughly mixed in a large tea-bag as a suspension in
15 dichloromethane {DCM). The resin mixture was dried under vacuum, then
divided
into equivalent portions and resealed in 70 labeled tea-bags, each tea-bag now
containing a mixture of the 17 aminobenzoic acids. This was followed by
reaction
with 70 aldehydes, each differing by their RS substituent, and 4-
methoxystyrene in the
presence of trifluoroacetic acid. After washing with a series of solvents, the
resins
2 0 were dried under vacuum and the mixtures individually cleaved from the
MBHA resin
using a hydrogen fluoride (HF) procedure. The individual mixtures varying at Y-
R',
Rz, R3 or R4 and constant ai R5, each a mixture containing 34 individual
compounds,
including enantiomers, can then be tested for biological activity using any
one of a
variety of screening assays, such as those described above or others well
known in the
2 5 art.
The individual aminobenzoic acids which were used to prepare the
library of 2380 THQs include the following: anthranilic acid, 2-amino-4-

1 Co~_ling of Aminobenzoic Acids to MBHA Resin.
Seventeen polypropylene mesh packets (tea-bags, ~2" square, 65~;
McMaster Carr, Chicago, IL) of (5 g, 0.89 meq/g) MBHA resin were prepared,
washed with DCM (2X, ~ 5 ml each), neutralized with 5%
diisopropylethylamine/dichloromethane (DIEA/DCM) (3X, ~ S ml each), and washed
with DCM (2X, ~ 5 ml each). Each resin packet was individually coupled
overnight
(~ 16 hrs) by adding SX aminobenzoic acid (0.5 M)in 1:1 DMF/DCM solvent system
followed by SX diisopropylcarbodiimide (DIC) in DCM (0.5 M) and
hydroxybenzotriazole (HOBt) (SX). Following coupling completion, resin packets
were washed with DCM (2X), DMF (2X), and DCM (1X) and MeOH (1X). After
drying under vacuum 4-12 hrs, each individual packet was then opened and a
proportional amount of resin transferred to a large Tea-bag (~5" square) which
was
sealed and shaken in DCM for 1 hour. After a MeOH wash the mixed resin was
dried
under vacuum and then 30 mg portions (calc. 25 micromole) distributed into
labeled
Tea-bags (~1.5 " square) for use in subsequent chemistry.

1. Cowling of L or D p-Nitrophenylalanine to MBHA Resin.
2 0 Polypropylene mesh packets (Tea-bags, ~5") of (5 g each, 0.89 meq/g)
MBHA resin were prepared, washed with DCM (2X, ~ 25 ml each), neutralized with
5% diisopropylethylamine/dichloromethane (DIEA/DCM} (3X, ~ 25 ml each), and
washed with DCM (2X, ~ 25 ml each). Each resin packet set is individually
coupled
2-4 hrs by adding 2.SX L or D N-BOC p-nitrobenzoic acid (0.5 M)in 1:1 DMF/DCM
2 5 solvent system followed by 2.SX diisopropylcarbodiimide (DIC) in DCM (0.5
M) and
HOBt (2.5X). Following coupling completion, resin packets were washed with DCM
(2X), DMF (2X), and DCM ( 1 X) and MeOH ( 1 X). The N-BOC protecting group was
removed by shaking the bags with a solution of 55% TFA in DCM at room
temperature for 30 mins. The liquid was decanted and the packets were washed
with
30 DCM (3X), 5% DIEA in DCM (3X). After drying under vacuum 4-12 hrs, each
individual packet was then opened and the resin transferred in 75 mg (calc. 63

subsequent
chemistry.
2 Acylation of L and D p-Nitrophenvlalanine.
Groups of the resin packets (2X 75 mg and a 30 mg) were individually
coupled with 170 different acids overnight (~16 hrs) by adding 5X acid (0.5 M)
in 1:1
DMF/DCM solvent system followed by 5X diisopropylcarbodiimide (DIC) in DCM
(0.5 M) and HOBt (SX). Following coupling completion, resin packets were
washed
with DCM (2X), DMF (2X), and DCM (1X) and MeOH (IX). The 30 mg bags from
each of the 170 acid reactions were cleaved by standard HF procedures and the
products analyzed (See Table 2 below). One of the 75 mg bags from each acid of
the
reaction was opened and combined into one large Tea-bag (~ 5" square) and each
was
then mixed in DCM for 30 min. After drying under vacuum the resin-bound acid
mixture sets were distributed in 30 mg portions into 1" Tea-bags for use in
subsequent
chemistry.
