TITLE

COMBINATORIAL PROCESS FOR PREPARING SUBSTITUTED INDANE

LIBRARIES

Field of the Invention This invention relates to the preparation of libraries of substituted indane compounds by combinatorial processes. These libraries are useful for discovery of lead compounds for drug development and improved assay kits.

Background of the Invention

Traditional chemical synthesis for drug discovery is done by individually creating, isolating, and identifying candidate compounds. Companies have long relied on their historical collections of compounds and compound collections from exchange agreements as sources of diverse structures for generating lead pharmaceutical compounds. All of these historical approaches have drawbacks.

Corporate collections of compounds may have a certain bias and medicinal chemists using traditional synthetic techniques cannot synthesize hundreds or thousands of diverse compounds to find promising leads. Combinatorial chemistry is a relatively new technique for chemical synthesis. It fills the long felt need for a method to quickly generate highly diverse non-peptide compound libraries. Generally, diverse libraries containing a common scaffold which are substituted with a great variety of substituents. More recently, modern drug discovery has used the methods of combinatorial chemistry to generate large numbers (viz., about 10^ to 10^) of compounds with common scaffolds generically referred to as "libraries."

Combinatorial chemistry may be performed in a manner where libraries of compounds are generated as mixtures with complete identification of individual compounds postponed until after positive screening results are obtained. However, a preferred form of combinatorial chemistry is

"parallel array synthesis" where individual reaction products (most often individual compounds) are synthesized together, but are retained in separate vessels. For example, the library compounds are held in the individual wells of 96 well microtiter plates. Use of standardized microtiter plates or equivalent apparatus is advantageous because such apparatus is readily manipulated by programmed robotic machinery.

Generally, combinatorial chemistry is conducted on a solid phase support, normally a polymer. A selected scaffold is cleavably tethered to the solid support by a chemical linker. Reactions are carried out to modify the scaffold while tethered to the solid support. In a final step, the product is cleaved and released from the solid support. Combinatorial chemistry evidences its utility by commercial success. Millions of dollars have been spent for recent purchases or cooperative associations of major pharmaceutical companies with small companies specializing in combinatorial chemistry (e.g., Glaxo's acquisition of Affymax, Marion Merrell Dow's purchase of Selectide, Proctor & Gamble with Houghten, Astra with Alanex, Pfizer with Oxford Asymmetry, Sandoz with Pharmacopeia, Solvay with Arqule, CIBA with Chiron, and Eli Lilly with Sphinx Pharmaceutical) .

To continue exploration of new libraries for pharmaceutical and agricultural lead compounds it is necessary to develop new chemistries which permit chemical novel scaffolds to be functionalized with highly diverse groups.

Summary of the Invention

This invention is an improved combinatorial process for making a library of indane compounds.

This invention is also a combinatorial library of indane compounds.

Detailed Description of the Invention

I. Definitions:

The following terms have the meaning defined below when used in this specification of the invention:

"Assay kit" means an assemblage of two cooperative elements, namely, (i) a wellplate apparatus, and (ii) biological assay materials.

"Biological assay materials" are materials necessary to conduct a biological evaluation of the efficacy of any library compound in a screen relevant to a selected disease state.

"Directed Library" is a collection of compounds created by a combinatorial chemistry process for the purpose of

optimization of the activity of a lead compound, wherein each library compound has a common scaffold, and the library, considered in its entirety, is a collection of closely related homologues or analogs to the lead compound (compare to "Diverse library").

"Diverse library" means a library where the substituents on the combinatorial library scaffold are highly variable in constituent atoms, molecular weight, and structure and the library, considered in its entirety, is not a collection of closely related homologues or analogs (compare to "Directed library") .

"Electrophile" means an electron seeking reagent. "Lead compound" means a compound in a selected combinatorial library for which the Assay kit has revealed significant activity relevant to a selected disease state.

"Leaving group" means a group capable of substitution by a nucleophile.

"Library" is a collection of compounds created by a combinatorial chemical process, said compounds having a common indane scaffold with one or more variable substituents.

"Library compound" means an individual reaction product (usually a single compound) in a library produced by the method of the invention. "Parallel array synthesis" means a method of conducting combinatorial chemical synthesis of libraries wherein the individual combinatorial library reaction products are separately prepared and stored without prior or subsequent intentional mixing. "Reaction zone" means the individual vessel location where the combinatorial chemical library compound preparation process of the invention is carried out and individual library compounds synthesized. Suitable reaction zones are the individual wells of a wellplate apparatus. "Scaffold" means the invariant region (viz., indane core) of the compounds which are members of a library.

"Simultaneous synthesis" means making of library of compounds within one production cycle of a combinatorial method (not making all library compounds at the same instant in time) .

"Solid support" means a functional resin such as a carboxyl functional resin, represented by the symbols,

"Substituents" are chemical radicals (excluding hydrogen) which are bonded to the scaffold through the combinatorial synthesis process. The different functional groups account for the diversity of molecules throughout the library and are selected to impart diversity of biological activity to the scaffold in the case of diverse libraries, and optimization of a particular biological activity in the case of directed libraries.

"Reagent" means a reactant, any chemical compound used in the combinatorial synthesis to place substituents on the scaffold of a library.

"Wellplate apparatus" means a structure capable of holding a plurality of library compounds in dimensionally fixed and defined positions.

"Indane" is a synonym for "indan" and is the nucleus represented by the structural formula:

II. General description of the indane combinatorial library:

The indane library of the invention is preferably a diverse combinatorial library comprising individual substituted indane library compounds represented by the general formula (I) :

wherein Ei and E2 are the same or different electrophilic group. The sources for diversity in the indane library compounds of the invention are the groups Ei and E2.

The indane library compounds of this invention are non- peptide, substantially non-naturally occurring molecules having a molecular weight range of from about 100 to about 800.

Preferred libraries contain indane library compounds wherein;

Ei and E2 are the same or different electrophilic groups preferably derived from an electrophilic reagent having a molecular weight of from about 30 to about 600 selected from the group consisting of; organic halides, acyl halides, sulfonic acid esters, organohaloformates, organosulfonyl halides, organic isocyanates, and organic isothiocyanates . Electrophilic groups for Ei and E2 include, but are not limited to C1-C10 alkyl, C2-C10 alkenyl, C2-C10 alkynyl, Ci- C10 alkoxy, C7-C12 aralkyl, C7-C12 alkaryl, C3-C10 cycloalkyl, C3-C10 cycloalkenyl, phenyl, substituted phenyl, toluyl, xylenyl, biphenyl, C2-C12 alkoxyalkyl, C1-C6 alkylsulfinyl, C1-C10 alkylsulfonyl, - (CH2)m~0- (C1-C10 alkyl) , aryl, substituted aryl, substituted alkoxy, fluoroalkyl, aryloxyalkyl, carbocyclic radical, substituted carbocyclic radical, heterocyclic radical, substituted heterocyclic radical, and nitroalkyl; where m is from 1 to 8.

Preferred electrophilic groups Ei and E2 groups derived from electrophilic reagents are independently selected from groups represented by the following structural formulae:

A diverse library of indane compounds (compounds diversely substituted at specific sites on an indane scaffold) was created by parallel array synthesis for its general utility in drug candidate screening, agricultural candidate screening, structure activity relationship studies, and/or clinical investigation (as well as other specific utilities described herein) .

III. Process of Making the Indane Libraries of the Invention:

Combinatorial chemistry may be used at two distinct phases of drug development. In the discovery phase highly diverse libraries are created to find lead compounds. In a second optimization phase, strong lead compounds are much more narrowly modified to find optimal molecular configurations. The method of this invention has applicability for making both diverse libraries of indane compounds useful for finding new lead compounds and directed libraries of indane compounds useful for optimizing a particular desired biological activity.

The compounds of formula (I) comprise the products of a multiple component combinatorial parallel array synthesis derived from multiple reactants comprising; a first reactant containing electrophilic group Ei; a second reactant containing electrophilic group E2; and a third reactant having an indane scaffold. Generally, the third reactant remains constant for all compounds prepared in the library. The sole source of

diversity for the indane scaffold is the first and second reactants.

The electrophilic group containing first and second reactants:

Electrophiles react with the amine nitrogen atoms pendant on the indane ring of Formula (I) . Alkylation and acylation reactions are suitable. Electrophilic reactants suitable for use in this step have a molecular weight of from abut 15 to 600 and are selected from organic halides, acyl halides, sulfonic acid esters, organohaloformates, organosulfonylhalides, organic isocyanates, and organic isothiocyanates.

To a solution of 1-indanone (25 g, 0.189 mol) in concentrated H ₂ SO ₄ (84 ml) at 0°C was added a solution of KNO3 (8.33 g, 0.0824 mol) in H ₂ S0 (40 ml) to maintain an internal temperature below 15°C. After stirring at 0°C for 1 hour, the reaction mixture was poured into crushed ice and stirred vigorously for 30 min. The suspension was then filtered, air dried, and purified by LC (5% ethyl acetate/toluene) to provide 1 (18.90 g, 56%) as a pale yellow solid.

2. A solution of 1 (18.90 g, 0.107 mol) in methanol (300ml) was cooled to 0°C and NaBH ₄ (4.04g.0.107 mol) was added in several small portions. The reaction was then stirred overnight at 25°C. The solution was quenched at 0°C with methanolic HCl (200 ml) , concentrated under reduced pressure, redissolved in CH2CI2, washed with H ₂ O, and the organic layer reconcentrated to provide the crude alcohol as a brown solid.

3. To a solution of crude alcohol in toluene (300 ml) was added a catalytic amount of p-toluenesulfonic acid and the reaction was refluxed for 1 hour using a Dean Stark trap to remove the H2O. The organic layer was washed with saturated NaHC0 ₃ (3 x 200 ml), dried over MgSθ ₄ , solvent removed under vacuum, and the product recrystallized from methanol to afford 3 (13.41g, 78% over two steps) as a tan solid.

Indane Library Process Methodolody:

Reaction Medium - The reaction medium may be any liquid which is non-reactive with the reactants used in the library synthesis and is a non-solvent for the solid support. It is generally advantageous to have the electrophilic reagent soluble in the reaction medium.

Typical reaction media useful in the processes of the invention are methanol, chloroform, dimethylacetamide, tetrahydrofuran, dimethylformamide, methylene chloride, and acetonitrile. The Reaction Zone - the process of the invention may be carried out in any vessel capable of holding the liquid reaction medium and having inlet and outlet means. Preferably the process of the invention is carried out in containers adaptable to parallel array syntheses. Most preferably, the indane library is formed in an 8 by 12 matrix of reaction vessels such as glass tubes is a dimensionally stable holder or the wells of standard wellplates, such as the 96 well wellplate illustrated in Fig.l. Each well may be filled by multiple delivery apparatus, automated or robotic apparatus, any of which may be either manually or computer controlled.

The diverse indane library of this invention may take the form of a plurality of wellplates, each wellplate having wells containing a separate reaction product (library compound) . In such cases, the library compounds are conveniently identified by their wellplate number and "x" column and "y" wellplate row coordinates.

A preferred technique for practicing the process of the invention is parallel array synthesis. With parallel array synthesis individual reaction products are prepared in each of multiple reaction zones. The amount of electrophilic reagent introduced into each reaction zone will depend on the desired amount of each library compound that is needed for conducting biological assays, archival storage and other related needs. Typically, the desired amount of individual reaction product is from 1 microgram to 50 milligrams.

The reaction zone is maintained at a temperature and for a time sufficient to permit substantial reaction of the solid phase indane compound and the electrophilic reagent(s). The time, temperature, and pressure of the combinatorial reaction zones used for the creation of library compounds are not critical aspects of the invention. Reaction times for a

single step of the reaction are generally from 0.1 seconds to 72 hours, with times of 1 hour to 24 hours being most often used. The temperature of the reaction may be any temperature between the freezing point and the boiling point of the liquid reaction medium, but is generally between -10°C and +60°C, with 10°C to 40°C being preferred and ambient temperatures (about 20°C-30°C) being most preferred. The reactions may be conducted at subatmospheric pressure or superatmospheric pressure (viz., 60Kg./m2 - 21000 absolute) , but ambient atmospheric pressure (about 10330 Kg./m^, absolute) is most often used.

Endpoint determination - The completion of the reaction may be determined by a number of conventional techniques. One method is to use thin layer chromatography. Sequence of Operation - Within each process step the addition of the reactants to the reaction zone may take place in any order. For example, the solid supported reaction product may be initially added to the reaction zone followed by addition of the electrophilic reagent containing the group Ei, then electrophilic reagent containing the group E2, or vice versa.

IV. Solid Supported Intermediate Indane Libraries and Library Compounds: A library of intermediate substituted indane compounds comprising a plurality of diverse compounds, wherein each intermediate has the formula (II) is created in the process of the preceding section prior to cleavage from the resin solid support . These intermediates are themselves useful and stable compounds which may be stored and used at a later time for generating the indane library compounds of the invention. These indane intermediates are represented by formula (II) ;

wherein Ei and E2 are the same or different electrophilic groups.

V. Antineoplastic Activity of the Indane Library Compounds:.

Neoplastic diseases, characterized by the proliferation of cells not subject to the normal control of cell growth, are a major cause of death in humans and other mammals. Clinical experience in cancer chemotherapy has demonstrated that new and more effective drugs are desirable to treat these diseases.

The present invention provides a method of alleviating neoplastic diseases comprising administering to a subject an effective amount of a pharmaceutical or veterinary composition containing a library compound corresponding to formula (I) . Moreover, combination chemotherapy, chemotherapy utilizing compounds of Formula (I) in combination with other neoplastic agents, is also provided by the subject invention.

In general, the dosage required for therapeutic effect will vary according to the type of use, mode of administration, as well as the particularized requirements of the individual hosts. Typically, dosages will range from about 0.001 to 1000 mg/kg, and more usually 0.01 to 10 mg/kg of the host body weight. The compound of Formula I, with or without additional anti-neoplastic agents, may be formulated into therapeutic compositions as natural or salt forms. Pharmaceutically acceptable non-toxic salts include base addition salts which may be derived from inorganic bases such as for example, sodium, potassium, ammonium, calcium, or ferric hydroxides, and such organic bases as isopropylamine,

trimethylamine, 2-ethylamino ethanol, histidine, procaine, and the like. Such salts may also be formed as acid addition salts with any free cationic groups and will generally be formed with inorganic acids such as for example, hydrochloric or phosphoric acids or organic acids such as acetic, oxalic, tartaric, mandelic, and the like. Additional excipients which further the invention are provided to the skilled artisan for example in the U.S. Pharmacopeia .

The compounds are screened for minimum inhibitory concentrations against KB, a human nasopharyngeal carcinoma cell line, LoVo, a human colorectal adenocarcinoma cell line. The Corbett assay, see Corbett, T.H. et al. Cvtotoxic Anticancer Druσs: Models and Concepts for Drug Discovery and Development, pp 35-87, Kluwer Academic Publishers: Norwell, 1992. see also, Valeriote, et al. Discovery and Development of Anticancer Aσents; Kluwer Academic Publishers, Norwell, 1993.

The most active compounds are further evaluated for cytotoxicity against four different cell types, for example a murine leukemia, a murine solid tumor, a human solid tumor, and a low malignancy fibroblast using the Corbett assay.

The compounds are further evaluated against a broad spectrum of murine and human tumors implanted in mice, including drug resistant tumors. Tumor burden (T/C) (mean tumor burden in treated animals verses mena tumor burden in untreated animals) are used as a further assessment. T/C values that are less than 42% are considered to be active by National Cancer Institute Standards; T/C values less than 10% are considered to have excellent activity and potential clinical activity by National Cancer Institute standards.

While it is possible to administer a compound of the invention directly without any formulation, the compounds are preferably employed in the form of a pharmaceutical formulation comprising a pharmaceutically acceptable excipient and at least one compound of the invention. Such compositions contain from about 0.1 percent by weight to

about 90.0 percent by weight of a present compound. As such, the present invention also provides pharmaceutical formulations comprising a compound of the invention and a pharmaceutically acceptable excipient therefor. In making the compositions of the present invention, the active ingredient is usually mixed with an excipient which can be a carrier, or a diluent or be diluted by a carrier, or enclosed within a carrier which can be in the form of a capsule, sachet, paper or other container. When the carrier serves as a diluent, it can be a solid, semi-solid, or liquid material which acts as a vehicle, excipient, or medium for the active ingredient. Thus, the composition can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, emulsions, solutions, syrups, suspensions, aerosols (as a solid or in a liquid medium) , and sof and hard gelatin capsules.

The compounds of the invention may be delivered transdermally, if desired. Transdermal permeation enhancers and delivery systems, including patches and the like, are well known to the skilled artisan.

VI. Wellplate Apparatus containing library compounds prepared bv the process of the invention:

The processes of making the indane library of the invention may be conveniently carried out in a wellplate apparatus such as illustrated in Fig. 1, hereinafter described. It is particularly advantageous to carry out the method of the invention in a standard wellplate apparatus such as a plastic 96 well microtiter plate.

Typically, the wellplate apparatus is in the form of a rigid or semi-rigid plate, said plate having a common surface containing openings of a plurality of vessels arranged in rows and columns. A standard form of wellplate apparatus is a rectangular plastic plate having 8 rows and 12 columns (total 96) of liquid retaining depressions on its surface. A wellplate apparatus may optionally have other elements of structure such as a top or cover (e.g., plastic or foil), a bottom in a form such as a plate or reservoir, clamping means

to secure the wellplate and prevent loss of its contained compounds.

VII. The wellplate apparatus of the invention: A wellplate inoculated with the novel indane library compounds of the invention is itself a new construct or apparatus which has particular utility in an assay kit used to discover lead compounds.

VIII. Detailed Description of the Drawings
