Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit under 35 U.S.C. §119(e) to co-pending U.S. Provisional Application Ser. No. 60/984,918, filed Nov. 2, 2007, which is hereby incorporated by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to new heterocyclic compositions that are useful for inhibiting abnormal growth of certain cell types. The invention is directed to certain substituted thieno[3,2-d]pyrimidines, thieno[2,3-d]pyrimidines, thieno[3,2-b]pyridines, thieno[2,3-b]pyridines, and pyrrolo[2,3-d]pyrimidines, their corresponding pharmaceutically acceptable salts, and methods for their preparation and use. The substituted thienopyrmidines, thienopyridines, and pyrrolopyrmidines inhibit growth of tumor cells, which contain oncogenic forms of Receptor Tyrosine Kinases, K-Ras and B-Raf kinase. 
       BACKGROUND OF THE INVENTION 
       [0003]    B-Raf kinase is one of three known Raf oncoprotein kinases involved in transmission of mitogenic and anti-apoptotic signals. B-Raf encodes a Ras-regulated kinase that mediates cell growth and malignant transformation pathway activation that controls cell growth and survival. Activation of a Ras/Raf/MEK pathway results in a cascade of events from the cell surface to the cell nucleus, ultimately affecting cell proliferation, apoptosis, differentiation and transformation. Activating B-Raf mutations have been found in 66% of malignant melanomas and in a smaller fraction of other cancers including those of the colorectum, as reported by Davies H., et al. (2002)  Nature  417:906 and by Rajagopalan H., et al. (2002) Nature 418:934. Recently, B-raf has been shown to be frequently mutated in various human cancers, as described by Wan et al. (2004) Cell 116:855-867. Therefore, it is desirable to identify and characterize compounds that inhibit growth of tumor cells, which contain oncogenic forms of Receptor Tyrosine Kinases, K-Ras and B-Raf kinase. 
         [0004]    Certain thienopyrimidines, thienopyridines, and pyrrolopyrimidines have been noted as kinase inhibitors. For example, U.S. Pat. Appl. Publ. No. 2007/0082880 A1 describes a group of thieno[2,3-b]pyridine-5-carbonitriles as protein kinase inhibitors which preferably have heteroaryls or bicyclic aryls such as indolyl or benzimidazole substituted on the pyridine ring. Those compounds differ in the placement and nature of the substituents relative to the compounds disclosed herein. 
         [0005]    Variably-substituted thieno[3,2-d]pyrimidine, thieno[2,3-d]pyrimidine, thieno[3,2-b]pyridine, thieno[2,3-b]pyridine, and pyrrolo[2,3-d]pyrimidine compositions in accordance with embodiments of the present invention selectively inhibit B-Raf kinase activity and are useful for treating disorders mediated by B-Raf kinase and for the treatment of cancer including, for example, but not limited to, colonic polyps, in mammals.

         [0065]    Reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformation being effected. It is understood by those skilled in the art of organic synthesis that the various functionalities present on the molecule must be consistent with the chemical transformation proposed. This may necessitate routine judgment as to the order of synthetic steps, and the need for protecting groups for remote functionalities. 
         [0066]    Compounds of the present invention may be prepared as illustrated in the examples and in the following reaction schemes. 
         [0067]    Referring now to Scheme 1, compounds of formula Ia can be obtained via coupling of compound II with boronic acid III, wherein R 11  is —H or —W—R 1 , in the presence of a palladium catalyst, for example tetrakistriphenylphospinepalladium, in a mixture of DME and aqueous sodium bicarbonate.

         [0068]    When R 11  is H, the resulting coupling product Ie can react with electrophiles, including, but not limited to, acid chlorides, isocyanates, anhydrides, and activated anhydrides and esters such as 1-hydroxybenzotriazole esters and mixed carboxylic phosphoric acid anhydrides generated by the reaction of a carboxylic acid with an activating agent such as 1-hydroxybenzotriazole (HOBT), diphenylphosphoryl azide (DPPA), and similar agents known by those skilled in the art, to introduce —W—R 1  and obtain compounds of formula Ia. 
         [0069]    The compound II may be available from commercial sources or known literature procedures, or may be prepared as illustrated in the following reaction schemes 2 to 4. 
         [0070]    In reference to Scheme 2, compound IIa can be prepared from chloro-substituted thienopyrimidine and thienopyridine derivatives IV wherein one of X′ and Z is —S— and the other of X′ and Z is ═C(R 3 )— using methods analogous to those described in U.S. Pat. Appl. Publ. No. 2007/0082880 A1. Chloro-substituted thieno derivatives IV are treated with lithium diisopropylamide in an inert solvent with cooling, preferably to about —78° C., followed by addition of iodine to obtain intermediate V. Intermediate V undergoes a coupling reaction with a boronic acid of formula R 2 —B(OH) 2  in the presence of a palladium catalyst, for example tetrakis-triphenylphospinepalladium, in a mixture of DME and aqueous sodium bicarbonate to yield intermediate IIa. Alternatively, CO 2  can be used in place of I 2 , and the coupling step omitted to obtain carboxylate derivatives of II, wherein R 2  is —C(O)OR 7  or —C(O)NR 7 R 7 .

         [0077]    Pharmaceutically acceptable salts of the compounds of formula Ia with an acidic moiety may be formed from organic and inorganic bases. For example with alkali metals or alkaline earth metals such as sodium, potassium, lithium, calcium, or magnesium or organic bases and N-tetraalkylammonium salts such as N-tetrabutylammonium salts. Similarly, when a compound of this invention contains a basic moiety, salts may be formed from organic and inorganic acids. For example salts may be formed from acetic, propionic, lactic, citric, tartaric, succinic, fumaric, maleic, malonic, mandelic, malic, phthalic, hydrochloric, hydrobromic, phosphoric, nitric, sulfuric, methanesulfonic, naphthalenesulfonic, benzenesulfonic, toluenesulfonic, camphorsulfonic, and similarly known acceptable acids. Suitable examples of pharmaceutically acceptable salts include, but are not limited, to sulfate; citrate, acetate; oxalate; chloride; bromide; iodide; nitrate; bisulfate; phosphate; acid phosphate; isonicotinate; lactate; salicylate; acid citrate; tartrate; oleate; tannate; pantothenate; bitartrate; ascorbate; succinate; maleate; gentisinate; fumarate; gluconate; glucaronate; saccharate; formate; benzoate; glutamate; methanesulfonate; ethanesulfonate; benzenesulfonate; p-toluenesulfonate; pamoate (i.e., 1,1′-methylene-bis-(2-hydroxy-3-naphthoate)); and salts of fatty acids such as caproate, laurate, myristate, palmitate, stearate, oleate, linoleate, and linolenate salts. The compounds can also be used in the form of esters, carbamates and other conventional prodrug forms, which when administered in such form, convert to the active moiety in vivo. 
         [0078]    The present invention accordingly provides a pharmaceutical composition, which comprises an effective amount of a compound of formula lain combination or association with a pharmaceutically acceptable carrier. Pharmaceutical compositions are prepared in accordance with acceptable pharmaceutical procedures, such as described in  Remington&#39;s Pharmaceutical Sciences,  17th edition, ed. Alfonoso R. Gennaro, Mack Publishing Company, Easton, Pa. (1985). Pharmaceutically acceptable carriers are those that are compatible with the other ingredients in the formulation and biologically acceptable. As used herein, the term “effective amount” refers to the amount of active compound or pharmaceutical agent that elicits the biological or medicinal response in a tissue, system, animal, individual or human that is being sought by a researcher, veterinarian, medical doctor or other clinician, which includes one or more of the following: (1) preventing the disease; for example, preventing a disease, condition or disorder in an individual that may be predisposed to the disease, condition or disorder but does not yet experience or display the pathology or symptomatology of the disease; (2) inhibiting the disease; for example, inhibiting a disease, condition or disorder in an individual that is experiencing or displaying the pathology or symptomatology of the disease, condition or disorder (i.e., arresting or slowing further development of the pathology and/or symptomatology); and (3) ameliorating the disease; for example, ameliorating a disease, condition or disorder in an individual that is experiencing or displaying the pathology or symptomatology of the disease, condition or disorder (i.e., reversing the pathology and/or symptomatology). 
       Standard Biological and Pharmacological Test Procedures  
       [0079]    Evaluation of representative compounds of this invention in standard pharmacological test procedures indicated that the compounds of this invention possess significant anticancer activity and are in particular inhibitors of B-Raf kinase. Based on the activity shown in the standard pharmacological test procedures, the compounds of this invention are therefore useful as antineoplastic agents. In particular, these compounds are useful in treating, inhibiting the growth of, or eradicating neoplasms such as those of the breast, kidney, bladder, mouth, larynx, esophagus, stomach, colon, ovary, lung, pancreas, liver, prostate and skin. 
       B-Raf Kinase to MEK1 ELISA  
       [0080]    Representative examples of formula Ia were tested as B-Raf Kinase inhibitors that can inhibit growth of tumor cells that contain oncogenic forms of Receptor Tyrosine Kinases or K-Ras, or B-Raf kinase using the following Kinase Assay Protocol. 
         [0081]    Reagents: Flag/GST-tagged recombinant human B-Raf produced in Sf9 insect cells, human non-active Mek-1-GST (recombinant protein produced in  E. coli ); and a phospho-MEK1 specific poly-clonal Ab from Cell Signaling Technology (Cat. #9121). 
         [0082]    B-Raf1 Kinase Assay Procedure: B-Raf-1 is used to phosphorylate GST-MEK1. MEK1 phosphorylation is measured by a phospho-specific antibody (from Cell Signaling Technology, Cat. #9121) that detects phosphorylation of two serine residues at positions 217 and 221 on MEK1.

         [0106]    The compounds of this invention may be formulated neat or may be combined with one or more pharmaceutically acceptable carriers for administration. For example, solvents, diluents and the like, and may be administered orally in such forms as tablets, capsules, dispersible powders, granules, or suspensions containing, for example, from about 0.05 to 5% of suspending agent, syrups containing, for example, from about 10 to 50% of sugar, and elixirs containing, for example, from about 20 to 50% ethanol, and the like, or parenterally in the form of sterile injectable solution or suspension containing from about 0.05 to 5% suspending agent in an isotonic medium. Such pharmaceutical preparations may contain, for example, from about 0.05 up to about 90% of the active ingredient in combination with the carrier, more usually between about 5% and 60% by weight. 
         [0107]    In some embodiments, the formulations are administered transdermally which includes all methods of administration across the surface of the body and the inner linings of body passages including epithelial and mucosal tissues. Such administration may be in the form of a lotion, cream, colloid, foam, patch, suspension, or solution. 
         [0108]    The effective dosage of active ingredient employed may vary depending on the particular compound employed, the mode of administration and the severity of the condition being treated. However, in general, satisfactory results are obtained when the compounds of the invention are administered at a daily dosage of from about 0.5 to about 1000 mg/kg of animal body weight, optionally given in divided doses two to four times a day, or in sustained release form. For most large mammals the total daily dosage is from about 1 to 1000 mg, preferably from about 2 to 500 mg. Dosage forms suitable for internal use comprise from about 0.5 to 1000 mg of the active compound in intimate admixture with a solid or liquid pharmaceutically acceptable carrier. This dosage regimen may be adjusted to provide the optimal therapeutic response. For example, several divided doses may be administered daily or the dose may be proportionally reduced as indicated by the exigencies of the therapeutic situation. 
         [0109]    The compounds of this invention may be administered orally as well as by intravenous, intramuscular, or subcutaneous routes. Solid carriers include starch, lactose, dicalcium phosphate, microcrystalline cellulose, sucrose and kaolin, while liquid carriers include sterile water, polyethylene glycols, non-ionic surfactants and edible oils such as corn, peanut and sesame oils, as are appropriate to the nature of the active ingredient and the particular form of administration desired. Adjuvants customarily employed in the preparation of pharmaceutical compositions may be advantageously included, such as flavoring agents, coloring agents, preserving agents, and antioxidants, for example, vitamin E, ascorbic acid, BHT and BHA. 
         [0110]    The preferred pharmaceutical compositions from the standpoint of ease of preparation and administration are solid compositions, particularly tablets and hard-filled or liquid-filled capsules. Oral administration of the compounds is sometimes desirable. 
         [0111]    In some cases it may be desirable to administer the compounds directly to the airways in the form of an aerosol. 
         [0112]    The compounds of this invention may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt may be prepared in water suitably mixed with a surfactant such as hydroxy-propylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms. 
         [0113]    The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier may be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oils. 
         [0114]    For the treatment of cancer, the compounds of this invention may be administered in combination with other antitumor substances or with radiation therapy. These other substances or radiation treatments may be given at the same or at different times as the compounds of this invention. These combined therapies may effect synergy and result in improved efficacy. For example, the compounds of this invention may be used in combination with mitotic inhibitors such as taxol or vinblastine, alkylating agents such as cisplatin or cyclophosamide, antimetabolites such as 5-fluorouracil or hydroxyurea, DNA intercalators such as adriamycin or bleomycin, topoisomerase inhibitors such as etoposide or camptothecin, antiangiogenic agents such as angiostatin, and antiestrogens such as tamoxifen. 
         [0115]    As used in accordance with this invention, the term “providing an effective amount of a compound” means either directly administering such compound, or administering a prodrug, derivative, or analog which will form an effective amount of the compound within the body. 
         [0116]    Methods of administration of a pharmaceutical composition of the invention are not specifically restricted, and can be administered in various preparations depending on the age, sex, and symptoms of the patient. For example, tablets, pills, solutions, suspensions, emulsions, granules and capsules may be orally administered. Injection preparations may be administered individually or mixed with injection transfusions such as glucose solutions and amino acid solutions intravenously. If necessary, the injection preparations are administered singly intramuscularly, intracutaneously, subcutaneously or intraperitoneally. Suppositories may be administered into the rectum. 
         [0117]    The amount of the compound of formula Ia contained in a pharmaceutical composition according to the present invention is not specifically restricted, however, the dose should be sufficient to treat, ameliorate, or reduce the targeted symptoms. The dosage of a pharmaceutical composition according to the present invention will depend on the method of use, the age, sex, and condition of the patient. 
         [0118]    The present invention also provides methods of inhibition and treatment further comprising administering an additional inhibitor of a oncopprotein kinase of the Ras/Raf/MEK pathway. 
         [0119]    The pharmaceutical compositions of the present invention may comprise the compound of the present invention alone or in combination with other oncoprotein kinase-inhibiting compounds or chemotherapeutic agents. Chemotherapeutic agents include, but are not limited to exemestane, formestane, anastrozole, letrozole, fadrozole, taxane and derivatives such as paclitaxel or docetaxel, encapsulated taxanes, CPT-11, camptothecin derivatives, anthracycline glycosides, e.g., doxorubicin, idarubicin, epirubicin, etoposide, navelbine, vinblastine, carboplatin, cisplatin, estramustine, celecoxib, tamoxifen, raloxifen, Sugen SU-5416, Sugen SU-6668, and Herceptin. 
         [0120]    The following examples further describe and demonstrate features of the present invention. The examples are given solely for the purpose of illustration and are not to be construed as a limitation of the present invention.

     Step 1: 6-pyridin-4-yl-1H-thieno[2,3-d]pyrimidin-4-one 
       [0139]    A reaction mixture of 2-amino-5-pyridin-4-yl-thiophene-3-carboxylic acid ethyl ester (prepared according to the procedure described in PCT Int. Appl. WO 2004/041813 A1) (6.4 g, 26 mmol), formamidine acetate (8.1 g, 77 mmol) in 100 mL of methoxyethanol was refluxed for 6 hours. The reaction mixture was cooled to room temperature and then 50 mL of water was added. After filtration and washing with 200 mL of water and 50 mL of ether, the title compound (5.2 g, 88% yield) was obtained as a white solid. MS: m/z 230 [M+H].  1 H NMR (DMSO-d 6 ): δ 9.0 (s, 1H), 8.6 (d, 2H), 8.2 (s, 1H), 8.15 (s, 1H), 7.8 (d, 2H).
