Title: Farnesyl protein transfer inhibitors for the treatment of inflammatory bowel disease

Description:
[0001] The present invention relates to the new use of certain farnesyl protein transferase inhibitors in the manufacture of a medicament for the treatment of inflammatory bowel disease.  
       [0002] Inflammatory bowel disease (IBD) identifies a group of chronic inflammatory disorders involving the (mainly) lower gastrointestinal tract. Although the exact aetiology of these disorders remains elusive, enviromental, genetic and immunological factors are implicated. Inflammatory bowel diseases such as Crohn&#39;s disease and ulcerative colitis are chronic progressive inflammatory conditions, with high morbidity, and potentially life-threatening complications (e.g. toxic megacolon, increased risk for colon cancer).  
       [0003] Ulcerative colitis involves an inflammatory reaction affecting the colon. The colon appears ulcerated and hemorrhaged. The inflammation is generally uniform and continuous and often involves the rectum. The major symptoms of ulcerative colitis include bloody diarrhea or constipation, abdominal pain, signs of dehydration, anemia, fever and weight loss. Extracolonic manifestations may include arthritis, evidence of liver disease, skin disease and lung disease.  
       [0004] Crohn&#39;s disease is characterized by inflammation extending through all layers of the intestional wall and often including the mesenteric lymph nodes. The inflammations may penetrate the mucosa and coalesce to form channels called fistulas and fissures. In Crohn&#39;s disease inflammations of the bowel are often discontinous and often granulomatous (see Horrison&#39;s Priciples of Internal Medicine, thirteenth ed., 1994, by McGraw-Hill, Inc. ISBN 0-07-032370-4, pg., 1403-1416).  
       [0005] Current therapies include but are not limited to treatment with aminosalicylates (e.g. sulfasalazine, olsalazine), corticosteroids (prednisolone, budenoside), and immuno-modulating drugs (azathioprine, 6-MP). Molecules which target specific steps in the inflammatory cascade, have been recently introduced or are under investigation for the treatment of IBD. However, approximately 25% of IBD patients will require surgery (colectomy) during the course of the disease. Surgical procedures are expensive, and associated with increased mortality and morbidity. There is undoubtedly a need for effective treatment of IBD.  
       [0006] It is, therefore, an object of the present invention to provide a new method for the treatment of inflammatory bowel disease.

     [0196] The pharmaceutically acceptable acid or base addition salts as mentioned hereinabove are meant to comprise the therapeutically active non-toxic acid and non-toxic base addition salt forms which the compounds of formulae (I), (II), (III), (IV), (V), (VI), (VII), (VIII) and (IX) are able to form. The compounds of formulae (I), (II), (III), (IV), (V), (VI), (VII), (VIII) and (IX) which have basic properties can be converted in their pharmaceutically acceptable acid addition salts by treating said base form with an appropriate acid. Appropriate acids comprise, for example, inorganic acids such as hydrohalic acids, e.g. hydrochloric or hydrobromic acid; sulfuric; nitric; phosphoric and the like acids; or organic acids such as, for example, acetic, propanoic, hydroxyacetic, lactic, pyruvic, oxalic, malonic, succinic (i.e. butanedioic acid), maleic, fumaric, malic, tartaric, citric, methanesulfonic, ethanesulfonic, benzenesulfonic, p-toluenesulfonic, cyclamic, salicylic, p-aminosalicylic, pamoic and the like acids.  
     [0197] The compounds of formulae (I), (II), (III), (IV), (V), (VI), (VII), (VIII) and (IX) which have acidic properties may be converted in their pharmaceutically acceptable base addition salts by treating said acid form with a suitable organic or inorganic base. Appropriate base salt forms comprise, for example, the ammonium salts, the alkali and earth alkaline metal salts, e.g. the lithium, sodium, potassium, magnesium, calcium salts and the like, salts with organic bases, e.g. the benzathine, N-methyl-D-glucamine, hydrabamine salts, and salts with amino acids such as, for example, arginine, lysine and the like.  
     [0198] The terms acid or base addition salt also comprise the hydrates and the solvent addition forms which the compounds of formulae (I), (II), (III), (IV), (V), (VI), (VII), (VIII) and (IX) are able to form. Examples of such forms are e.g. hydrates, alcoholates and the like.  
     [0199] The term stereochemically isomeric forms of compounds of formulae (I), (II), (III), (IV), (V), (VI), (VII), (VIII) and (IX), as used hereinbefore, defines all possible compounds made up of the same atoms bonded by the same sequence of bonds but having different three-dimensional structures which are not interchangeable, which the compounds of formulae (I), (II), (III), (IV), (V), (VI), (VII), (VIII) and (IX) may possess. Unless otherwise mentioned or indicated, the chemical designation of a compound encompasses the mixture of all possible stereochemically isomeric forms which said compound may possess. Said mixture may contain all diastereomers and/or enantiomers of the basic molecular structure of said compound. All stereochemically isomeric forms of the compounds of formulae (I), (II), (III), (IV), (V), (VI), (VII), (VIII) and (IX) both in pure form or in admixture with each other are intended to be embraced within the scope of the present invention.  
     [0200] Some of the compounds of formulae (I), (II), (III), (IV), (V), (VI), (VII), (VIII) and (IX) may also exist in their tautomeric forms. Such forms although not explicitly indicated in the above formula are intended to be included within the scope of the present invention.  
     [0201] Whenever used hereinafter, the term “compounds of formulae (I), (II), (III), (IV), (V), (VI), (VII), (VIII) and (IX)” is meant to include also the pharmaceutically acceptable acid or base addition salts and all stereoisomeric forms.  
     [0202] Farnesyl protein transferase inhibitors can be prepared and formulated into pharmaceutical compositions by methods known in the art and in particular according to the methods described in the published patent specifications mentioned herein and incorporated by reference; for the compounds of formulae (I), (II) and (III) suitable examples can be found in WO-97/21701. Compounds of formulae (IV), (V), and (VI) can be prepared and formulated using methods described in WO 97/16443, compounds of formulae (VII) and (VIII) according to methods described in WO 98/40383 and WO 98/49157 and compounds of formula (IX) according to methods described in WO 00/39082 respectively. To prepare the aforementioned medicaments, a therapeutically effective amount of the particular compound, optionally in addition salt form, as the active ingredient is combined in intimate admixture with a pharmaceutically acceptable carrier, which may take a wide variety of forms depending on the form of preparation desired for administration. The carrier(s) must be acceptable in the sense of being compatible with the other ingredients of the formula and not deleterious to the recipient thereof.  
     [0203] These pharmaceutical compositions are desirably in unitary dosage form suitable, preferably, for systemic administration such as oral, rectal, percutaneous, or parenteral administration; or topical administration such as via inhalation, a nose spray, eye drops or via a cream, gel, shampoo or the like. For example, in preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols and the like in the case of oral liquid preparations such as suspensions, syrups, elixirs and solutions; or solid carriers such as starches, sugars, kaolin, lubricants, binders, disintegrating agents and the like in the case of powders, pills, capsules and tablets. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed.  
     [0204] For parenteral compositions, the carrier will usually comprise sterile water, at least in large part, though other ingredients, for example, to aid solubility, may be included. Injectable solutions, for example, may be prepared in which the carrier comprises saline solution, glucose solution or a mixture of saline and glucose solution. Injectable solutions containing compounds of formula (I) may be formulated in an oil for prolonged action. Appropriate oils for this purpose are, for example, peanut oil, sesame oil, cottonseed oil, corn oil, soy bean oil, synthetic glycerol esters of long chain fatty acids and mixtures of these and other oils. Injectable suspensions may also be prepared in which case appropriate liquid carriers, suspending agents and the like may be employed. In the compositions suitable for percutaneous administration, the carrier optionally comprises a penetration enhancing agent and/or a suitable wettable agent, optionally combined with suitable additives of any nature in minor proportions, which additives do not cause any significant deleterious effects on the skin. Said additives may facilitate the administration to the skin and/or may be helpful for preparing the desired compositions. These compositions may be administered in various ways, e.g., as a transdermal patch, as a spot-on or as an ointment. As appropriate compositions for topical application there may be cited all compositions usually employed for topically administering drugs e.g. creams, gellies, dressings, shampoos, tinctures, pastes, ointments, salves, powders and the like. Application of said compositions may be by aerosol, e.g. with a propellent such as nitrogen, carbon dioxide, a freon, or without a propellent such as a pump spray, drops, lotions, or a semisolid such as a thickened composition which can be applied by a swab. In particular, semisolid compositions such as salves, creams, gellies, ointments and the like will conveniently be used.  
     [0205] For rectal administration, the pharmaceutical compositions may be presented as suppositories or as enemas. For rectal administration wherein the carrier is a solid, unit dose suppositories are preferred. Suitable carriers include cocoa butter and other materials commonly used in the art.  
     [0206] It is especially advantageous to formulate the aforementioned pharmaceutical compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used in the specification and claims herein refers to physically discrete units suitable as unitary dosages, each unit containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. Examples of such dosage unit forms are tablets (including scored or coated tablets), capsules, pills, powder packets, wafers, injectable solutions or suspensions, teaspoonfuls, tablespoonfuls and the like, and segregated multiples thereof.  
     [0207] Preferably, a therapeutic effective amount of the medicament comprising a compound according to the present invention is administered orally or parenterally. Said therapeutically effective amount is the amount that is effective in treating or preventing inflammatory bowel disease. The amount of compound according to the present invention, which is required to achieve a therapeutic effect will, of course, vary with the particular compound, route of administration, the age and condition of the recipient, and the particular disorder being treated.  
     [0208] On the basis of the current data, it appears that a pharmaceutical composition comprising a compound of formulae (I), (II), (III), (IV), (V), (VI), (VII), or (VIII) and in particular (+)-6-[amino(4-chlorophenyl) (1-methyl-1H-imidazol-5-yl)methyl]-4-(3-chlorophenyl)-1-methyl-2(1H)-quinolinone (compound 75) as the active ingredient can be administered orally in an amount of from 10 to 1500 mg daily, either as a single dose or subdivided into more than one dose. A preferred amount ranges from 100 to 1,000 mg daily, including 50 to 1,000 mg daily. A particularly preferred dosage for such a compound is 300 mg administered twice daily. This treatment can be given either continuously or intermittently in cycles of 3-4 weeks with treatment given for 1-21 days per cycle.  
     [0209] The compounds according to the present invention may also be used in accordance with the present invention in combination with one or more IBD treatment agents, including agents known to have utility for alleviating the symptoms of inflammatory bowel disease, including but not limited to:  
     [0210] 1. Anti-inflammatory agents, e.g. sulfasalazine, olsalazine  
     [0211] 2. Agents that control intestinal tract infection e.g. antibiotics:  
     [0212] (i) penicillins, e.g. bacitracin  
     [0213] (ii) glycopeptides, e.g. vancomycin  
     [0214] 3. Steroids corticosteroids, e.g. prednisolone budenoside  
     [0215] 4. Immuno-modulating agents, e.g. azathioprine, 6-MP  
     [0216] 5. Agents for controlling diarrhea, e.g; cholestryramine  
     [0217] The various components of the combination described herein may be administered simultaneously (e.g. in separate or unitary compositions) or sequentually in either order and optionally via different routes.  
     [0218] Testing Method for Inflammatory Bowel Disease  
     [0219] The purpose of this study was to identify, characterize and document the preventative actions of compound 75 above, namely (+)-6-[amino(4-chlorophenyl) (1-methyl-1H-imidazol-5-yl)methyl]-4-(3-chlorophenyl)-1-methyl-2(1H)-quinolinone, a compound of formulae (I), in an experimental model of inflammatory bowel disease in mice.  
     [0220] Procedure  
     [0221] A group of female Swiss-Webster mice was received from Ace Animals, Inc., Boyertown, Pa. The animals were grouped housed (5 mice/cage) in plastic cages with water absorbent bedding. The animal room was temperature controlled and had a 12-hour light/dark cycle. The animals were fed Purina Rodent Chow #5012 and filtered tap water was supplied ad libitum by automatic watering system (during acclimation).  
     [0222] Following an acclimation period of 9 days, 40 healthy mice were selected for this study. The test animals were distributed (10 mice/group) into each one of the 4 test groups described below. There were no statistical significant differences between the mean group body weights.  
                                       GROUP NUMBER   PRODUCT ID   DOSE LEVEL (mg/kg)                  1   Vehicle no. DSS   0       2   Vehicle with DSS   0       3   Compound 75 with DSS   25 PO bid       4   Compound 75 with DSS   50 PO bid                                  
 
     [0223] Individual doses were calculated based on daily body weights. Prior to administration, Compound 75 was mixed with the vehicle (Beta cyclodextrin (40%) in 0.1 N HCL). This mixture was further diluted with 0.1 N HCL. The resulting mixture was then used to prepare the dilutions for groups 3 and 4. A 20% solution of Beta cyclodextrin in 0.1 N HCL was used for Groups 1 and 2 and constituted the vehicle control. Groups 2 through 4 were given a 5% w/w solution of dextran sulfate sodium (DSS) in distilled water substituted for their normal water supply (approximately 10 ml/mouse/day) from Days 0 through 6. Each group of animals received the appropriate amount of the test substance, as described above, by intubation using a stainless steel ball-tipped gavage needle attached to an appropriate syringe.  
     [0224] All mice were weighed daily and observed for signs of gross toxicity and behavioural changes, consistency of stool and presence of gross blood during the study. On Day 7, all animals were euthanized by CO 2  inhalation and necropsied. Following euthanasia, a stool sample was obtained from the colon of each animal and tested for occult blood (Quik-Cult, Laboratory Diagnostics Co., Morganville, N.J.). The colons were then removed and the length from the colo-cecal junction to the end of the distal rectum was measured. A segment of colon was collected from each animal and preserved in 10% formalin.  
     [0225] For each group, the disease activity index (DAI) was determined by evaluating changes in weight, Hemoccult positivity or gross bleeding and stool consistency using the following system.  
                              Criteria for Scoring Disease Activity Index *                             Score   Weight Loss (%)   Stool #   Blood in feces               0   0 or gain   Normal   Negative       1     1-4.9   —   +/−       2   5.0-9.9   Semi-solid   +       3   10.15   Diarrhoea   ++       4   &gt;15   Bloody diarrhoea   Groos blood                                  
 
     [0226] Data was analyzed using analysis of variance (single factor). Statistically methods included the Mann-Whitney test, ANOVA and Turkey-Kramer Multiple Comparisons test.  
     [0227] Statistical significance between test and control groups was established at a probability of p&lt;0.05.  
     [0228] Results and Conclusion  
     [0229] Compound 75 showed significant activity in prevention of colitis produced by 5% Dextran Sulfate Sodium. Dose levels of 25 and 50 mg/kg PO bid prevented the shortening of the colon produced by DSS. The lower dose may have been more effective than the 50 mg/kg dose. Similar results were observed with the DAI (disease activity index) with or without the weight parameter. No significant protection against weight loss was noted with any dose. However, control mice receiving cyclodextrin lost weight over the duration of the study. In most studies vehicle treated mice usually gain weight. The weight loss observed with cyclodextrin+DSS was greater than that normally observed. Due to the severity of the weight loss in the control DSS group the study was terminated one day early. Eight deaths were noted in the study, 2 in the vehicle+DSS group, 1 each at the 25 and 50 mg/kg dose.

     [0232] Individual doses were calculated based on daily body weights. Prior to administration, 50 mg of Compound 75 was diluted with 10 milliliters of 0.1N HCl (50 mg/kg for Group 5). The resulting solution was then further diluted twice, with 5 ml increments and used for the 25 (Group 4) and 12.5 (Group 3) mg/kg dose levels. The 0.1 N HCl was used for Groups 1 and 2 and constituted the vehicle control. Groups 2 through 5 were given a 5% w/w solution of dextran sulfate sodium (DSS) in distilled water substituted for their normal water supply (approximately 10 ml:mouse/day) from Days 0 through 7. Each group of animals received the appropriate amount of the test substance, as described above, by intubation using a stainless steel ball-tipped gavage needle attached to an appropriate syringe.  
     [0233] Results and Conclusion  
     [0234] In this study, DSS produced a typical degree of colonic inflammation and colonic shortening. However, there was not the significant loss of body weight observed in other studies. The use of 0.1 N HCl may have been a factor in the lack of weight loss. The use of the DAI, in which weight loss is an important component, underestimates the degree of colitis and therefore the disease activity index using presence of fecal blood and stool consistency (DAINWT) is probably a more reliable estimate of activity. The typical degree of colonic shortening was observed and this measure remains the most significant indication of the extent of colitis and the degree protection. Compound 75 produced a statistically significant protection at all doses based on DAI and DAINWT. The maximal effectiveness on prevention of colonic shortening was observed at the lowest dose tested (12.5 mg/kg PO daily). The degree of effectiveness on this compound compares favorably with other experimental compounds, which have been tested previously and also confirms the initial test done with twice a day dosing and administered in cyclodextrin. No deaths were observed during the duration of the experiment.
