Description

USE OF QUINAZOLINE DERIVATIVES AS TYROSINE KINASE INHIBITORS FOR TREATING COLONIC POLYPS
This invention relates to the use of certain quinazoline compounds in the treatment and inhibition of colonic polyps.
Colonic Polyps occur in both a familial pattern (Familial Adenomatous Polyps (FAP) and sporadically. FAP afflicts approximately 25,000 patients in the US: while it is estimated that sporadic adenomatous polyps (SAP) occur in approximately 2 million people per year in the US alone. All these patients are at risk for developing adenocarcinoma of the colon. In the case of FAP, that risk is virtually 100% and these patients usually undergo a colectomy at an early age. Patients with sporadic polyps are treated with polypectomy and require periodic colonoscopic examination because of their inherent risk of developing recurrent polyps. In fact, parents and siblings of these patients are also at increased risk for developing colorectal cancer.
The genetic basis for FAP has been linked to the presence of mutations in the APC gene. Similar APC mutations have been found in patients with sporadic polyps. Biochemically, the APC mutation occurs in conjunction with the increased expression of cyclooxygenase enzymes, particularly COX-2. These enzymes are essential for the production of prostenoids, (prostaglandin's; (PG's)) that mediate a number of functions in the bowel including motility, vascular tone, angiogenesis and mucosal protection. PG's are also purported to discourage apoptosis and this is proposed as an explanation for polyp formation.
The therapy of FAP and SAP has focused on inhibiting COX enzymes. Considerable evidence exists for the efficacy of COX inhibitors in reducing polyp formation. These COX inhibitors are predominantly NSAID's such as clinoril, sulindac, piroxicam and etodoloc, all of which appear to be equivalent in their action. A major problem with NSAID therapy has been the development of serious side effects including peptic ulceration, and cholestatic hepatitis and renal papillary necrosis. Long term therapy with NSAIDs for the treatment of polyps is therefore considered to be impractical.
It has recently been proposed that the activation and overexpression of COX-2 in adenomatous polyps is due to activation of the epidermal growth factor receptor (EGFR). EGFR stimulation by one of it's ligands - amphiregulin (AR), induces the nuclear targeting of COX-2, release of PG's and subsequent mitogenesis, in polarized colonic epithelial cells. COX-2 inhibitors have been shown to prevent this series of events.

wherein:
X is phenyl optionally substituted with one or more substituents selected from the group consisting of halogen, alkyl of 1-6 carbon atoms, alkoxy of 1-6 carbon atoms, hydroxy, trifluoromethyl, cyano, nitro, carboxy, carboalkoxy of 2-7 carbon atoms, carboalkyl of 2-7 carbon atoms, amino, and alkanoylamino of 1- 6 carbon atoms;
R and Rj are each, independently, hydrogen, halogen, alkyl of 1-6 carbon atoms, alkoxy of 1-6 carbon atoms, hydroxy, or trifluoromethyl; R2 is hydrogen, alkyl of 1-6 carbon atoms, alkoxy of 1-6 carbon atoms, hydroxy, trifluoromethyl; Y is a radical selected from the group consisting of
R3 is independently hydrogen, alkyl of 1-6 carbon atoms, carboxy, carboalkoxy of 1-6 carbon atoms, phenyl, or carboalkyl of 2-7 carbon atoms; n = 2-4; or a pharmaceutically acceptable salt thereof, with the proviso that each R3 of Y may be the same or different.
The pharmaceutically acceptable salts are those derived from such organic and inorganic acids as: acetic, lactic, citric, tartaric, succinic, maleic, malonic, gluconic, hydrochloric, hydrobromic, phosphoric, nitric, sulfuric, methanesulfonic, and similarly known acceptable acids.
The alkyl portion of the alkyl, alkoxy, carboalkoxy, carboalkyl, and alkanoylamino substituents include both straight chain as well as branched carbon chains, e.g. methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, s-butyl, t-butyl, n- pentyl or n-hexyl. Carboxy is defined as a -CO2H radical. Carboalkoxy of 2-7 carbon atoms is defined as a -CO2R" radical, where R" is an alkyl radical of 1-6 carbon atoms. Carboalkyl is defined as a -COR" radical, where R" is an alkyl radical of 1-6 carbon atoms. When used herein the term halogen refers to chlorine, bromine, iodine or fluorine. When X is substituted, it is preferred that it is mono- , di- , or tri- substituted, with monosubstituted being most preferred. When a compound of this invention contains an assymetric center, this invention covers the individual R and S entantiomers as well as the racemate with respect to such compound.

with:
i) an acid chloride of Formula 7, wherein Y is as defined above
ii) a mixed anhydride of Formula 8, wherein Y is as defmed above
or iii) a cyclic anhydride of Formula 11 wherein each R5 is independently hydrogen, phenyl, or alkyl of 1-6 carbon atoms

wherein X is as defined above.
The preparation of the compounds of this invention encompassed by Formula 9 is described below in Flowsheet A where R, Ri, R2, R3, X, and n are as defined above and R4 is alkyl of 1-6 carbon atoms (preferably isobutyl). Y' is a radical selected from the group consisting of:
wherein each R'3 is independently alkyl of 1-6 carbon atoms, carboxy, carboalkoxy of 1-6 carbon atoms, phenyl, or carboalkyl of 2-7 carbon atoms. According to the sequence of reaction outlined in flowsheet A, a 5-nitro-anthranilonitrile of Formula 2 is heated at about 100°C with or without solvent containing an excess of dimethylformamide dimethyl acetal to furnish an amidine of Formula 3. Heating a solution of amidine 3 and the aniline 4 in acetic acid for 1 to 5 hours gives the 6-nitro- 4-anilinoquinazolines of Formula 5 . Reduction of the nitro group of 5 using a reducing agent such as iron in an acetic acid-alcohol mixture at elevated temperature gives the 6-amino-4-anilinoquinazolines of Formula 6 . Acylation of 6 with either an acid chloride of Formula 7 or a mixed anhydride of Formula 8 (which is prepared from the corresponding carboxylic acid) in an inert solvent such as tetrahydrofuran (THF) in the presence of an organic base such as pyridine or triethylamine gives the compounds of this invention represented by Formula 9. In those cases where 7 or 8 have an asymmetric carbon atom, they can be used as the racemate or as the individual R or S entantiomers in which case the compounds of this invention will be in the racemic or R and S optically active forms, respectively. The 5-nitro-anthranilonitriles of Formula 2 needed to prepare the compounds of this invention are either already known to the art or can be prepared by procedures known in the art as detailed in the following references: Baudet, Recl.Trav.Chim.Pays-Bas, 43, 710 (1924); Hartmans, Recl.Trav.Chim.Pays- Bas, 65, 468, 469 (1946) ; Taylor et al., J.Amer.Chem.Soc, 82, 6058,6063 (1960); Taylor et al., J.Amer.Chem.Soc, 82, 3152,3154 (1960); Deshpande; Seshadri, Indian J.Chem., 11 , 538 (1973); Katritzky, Alan R.; Laurenzo, Kathleen S., J.Org.Chem., 51 (1986); Niclas, Hans-Joachim; Bohle, Matthias; Rick, Jens-Detlev; Zeuner,Frank; Zoelch, Lothar, Z.Chem., 25(4), 137-138 (1985).

The ability of the compounds of this invention to treat or inhibit colonic polyps was demonstrated in an in vivo standard pharmacological test procedure as described below. The compound of Example 9 was evaluated in this procedure, which emulates familial adenomatous polyps (FAP) in humans, as a representative compound of this invention. The Min mouse used in this test procedure, currently the best available model for FAP, is a strain which has lost both copies of the APC gene. These animals develop multiple intestinal polyps (Adenomas) that ultimately progress to form adenocarcinomas. The polyps that develop in Min mice express EGFR and have activated COX-2. NSAID's such as sulindac and etodoloc can reduce (but not eradicate) intestinal polyp formulation in these animals indicating that COX-2 and the ultimate production of PG's is likely responsible for these effects. The following briefly describes the procedure used and the results obtained in this standard pharmacological test procedure.
The compound of Example 9 was blended with a standard murine chow and animals were given ad libitum access to the food. Based on estimated food consumption, the compound of Example 9 was added at a concentration commensurate with animals ingesting 20 mg/kg/day. At day 30, 4 treated + 4 control (chow alone) animals were sacrificed and assessed for polyp number. All control animals had greater than 30 polyps in their bowel, while the treated animals had none. Identical results were observed at 60 days - when 15 animals/group were assessed. The control animals had greater than 30 (larger) polyps while the treated animals had none.
These data demonstrate that the compounds of this invention effectively inhibit polyp formation in animals having mutations in their APC genes. Based on the results obtained in this standard pharmacological test procedure, the compounds of this invention are useful in treating or inhibiting the formation of colonic polyps.
The compounds of this invention may 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. 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.
These active compounds 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. 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 preferred.
In some cases it may be desirable to administer the compounds directly to the airways in the form of an aerosol. These active compounds may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt can 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 preparation contain a preservative to prevent the growth of microorganisms.
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 syringabiUty 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 can 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. The preparation of representative examples of the compounds of this invention is described below.
