Description:
The present invention relates to compounds of formula I or pharmaceutically acceptable salts thereof, that selectively modulate, regulate, and/or inhibit signal transduction mediated by certain native and/or mutant protein kinases implicated in a variety of human and animal diseases such as cell proliferative, metabolic, allergic, and degenerative disorders. More particularly, these compounds are potent and selective native and/or mutant c-kit inhibitors. 
     BACKGROUND OF THE INVENTION 
     Protein Kinases are receptor type or non-receptor type proteins, which transfer the terminal phosphate of ATP to aminoacid residues, such as tyrosine, threonine, serine residues, of proteins, thereby activating or inactivating signal transduction pathways. These proteins are known to be involved in many cellular mechanisms, which in case of disruption, lead to disorders such as abnormal cell proliferation and migration as well as inflammation. 
     As of today, there are over 500 known Protein kinases. Included are the well-known Ab1, Akt1, Akt2, Akt3, ALK, Alk5, A-Raf, Axl, B-Raf, Brk, Btk, Cdk2, Cdk4, CdkS, Cdk6, CHK1, c-Raf-1, Csk, EGFR, EphA1, EphA2, EphB2, EphB4, Erk2, Fak, Fes, Fer, FGFR1, FGFR2, FGFR3, FGFR4, Flt-3, Fms, Frk, Fyn, Gsk3α, Gsk β, HCK, Her2/Erbb2, Her4/Erbb4, IGF1R, IKK beta, Irak4, Itk, Jak1, Jak2, Jak3, Jnk1, Jnk2, Jnk3, KDR, Kit, Lck, Lyn, MAP2K1, MAP2K2, MAP4K4, MAPKAPK2, Met, Mer, MNK1, MLK1, mTOR, p38, PDGFRα, PDGFRβ, PDPK1, PI3Kα, PI3Kβ, PI3Kγ, PI3Kδ, Pim1, Pim2, Pim3, PKC alpha, PKC beta, PKC theta, Plk1, Pyk2, Ret, ROCK1, ROCK2, RON, Src, Stk6, Syk, TEC, Tie2, TrkA, TrkB, Tyk2, VEGFR1/Flt-1, VEGFR2/Kdr, VEGFR3/Flt-4, Yes, and Zap70. 
     Abnormal cellular responses triggered by protein kinase-mediated events produce a variety of diseases. These include autoimmune diseases, inflammatory diseases, neurological and neurodegenerative diseases, cancer, cardiovascular diseases, allergies and asthma, Alzheimer&#39;s disease and hormone-related diseases. 
     Tyrosine kinases are receptor type or non-receptor type proteins, which transfer the terminal phosphate of ATP to tyrosine residues of proteins thereby activating or inactivating signal transduction pathways. These proteins are known to be involved in many cellular mechanisms, which in case of disruption, lead to disorders such as abnormal cell proliferation and migration as well as inflammation. 
     As of today, there are about 58 known receptor tyrosine kinases. Included are the well-known VEGF receptors (Kim et al., Nature 362, pp. 841-844, 1993), PDGF receptors, c-kit, Flt-3 and the FLK family. These receptors can transmit signals to other tyrosine kinases including Src, Raf, Frk, Btk, Csk, Abl, Fes/Fps, Fak, Jak, Ack, etc. 
     Among tyrosine kinase receptors, c-kit is of special interest. Indeed, c-kit is a key receptor activating mast cells, which have proved to be directly or indirectly implicated in numerous pathologies for which the Applicant filed WO 03/004007, WO 03/004006, WO 03/003006, WO 03/003004, WO 03/002114, WO 03/002109, WO 03/002108, WO 03/002107, WO 03/002106, WO 03/002105, WO 03/039550, WO 03/035050, WO 03/035049, U.S. 60/359,652, U.S. 60/359,651 and U.S. 60/449,861, WO 04/080462, WO 05/039586, WO 06/135721, WO 07/089,069, WO 07/124,369, WO 08/137,794, WO 08/063,888, WO 08/011,080, WO 09/109,071, WO 10/096,395. 
     It was found that mast cells present in tissues of patients are implicated in or contribute to the genesis of diseases such as autoimmune diseases (rheumatoid arthritis, inflammatory bowel diseases (IBD)), allergic diseases, bone loss, cancers such as solid tumors, leukaemia and GIST, tumor angiogenesis, inflammatory diseases, interstitial cystitis, mastocytosis, graft-versus-host diseases, infection diseases, metabolic disorders, fibrosis, diabetes and CNS diseases. In these diseases, it has been shown that mast cells participate in the destruction of tissues by releasing a cocktail of different proteases and mediators such as histamine, neutral proteases, lipid-derived mediators (prostaglandins, thromboxanes and leukotrienes), and various cytokines (IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-8, TNF-α, GM-CSF, MIP-1a, MIP-1b, MIP-2 and IFN-γ). 
     The c-kit receptor also can be constitutively activated by mutations leading to abnormal cell proliferation and development of diseases such as mastocytosis (D816V mutation) and various cancers such as GIST (c-kitΔ27, a juxtamembrane deletion). 
     Sixty to 70% of patients presenting with AML have blasts which express c-kit, the receptor for stem cell factor (SCF) (Broudy, 1997). SCF promotes growth of hematopoietic progenitors, and act as a survival factor for AML blasts. In some cases (1 to 2%) of AML, a mutation in a conserved residue of the kinase domain (Kit816) resulting in constitutive activation of c-kit has been described (Beghini et al., 2000; Longley et al., 2001). This gain of function mutation (Asp to Val/Tyr substitution) has been identified in mast cell leukemic cell lines and in samples derived from patients with mastocytosis (Longley et al., 1996). Preliminary results show that this mutation is expressed in most cases of systemic mastocytosis ([˜60%], P Dubreuil, AFIRMM, study in progress on about 300 patients). 
     GOAL OF THE INVENTION 
     The main objective underlying the present invention is therefore to find potent and selective compounds capable of inhibiting wild type and/or mutated protein kinase, in particular wild type and/or mutated tyrosine kinase, and more particularly wild type and/or mutated c-kit. 
     In connection with the present invention, we have discovered that compounds of formula I are potent and selective inhibitors of certain protein kinases such as wild type and/or mutated c-kit. These compounds are good candidates for treating diseases such as autoimmunes diseases, inflammatory diseases, cancers and mastocytosis.

     The compounds of the present invention may be prepared using the general protocol as follows. 
     The synthesis of the aminooxazole derivatives was undergone by firstly reacting aromatic aldehydes I with p-toluenesulfonylmethyl isocyanide (TosMIC) to prepare the corresponding arylsubstitued oxazole derivatives II using the method of Van Leusen et. al. ( Tetrahedron Lett.,  1972, 23, 2369) (Scheme 1). The non-commercial aldehydes were prepared using literature methods to introduce the aldehyde group either from the corresponding brominated aromatic compound using an organometallic reagent and DMF or from the oxidation of corresponding toluene according the method of Frey et. al. ( Tetrahedron Lett.,  2001, 39, 6815). 
     Secondly, those compounds II were then further functionalised by deprotonation of the oxazole moiety by a suitable organic base and subsequent electrophilic chlorination was used to prepare the 2-chlorooxazole coumpounds III. A direct nucleophilic displacement reaction by aniline compounds IV (wherein R′ is hydrogen), in the presence of a suitable solvent such as alcohol and with heating in elevated temperature, should generally afford the final target compounds V. Compounds V can also obtained by reacting compounds IV (wherein R′ is an acetyl group) and compounds III in the presence of sodium hydride and in a suitable solvent such as tetrahydrofurane or dimethylformamide (WO 2007/131953). 
     
       
                 
         
             
             
         
      
     
     Scheme 2 depicts the synthesis of the aminothiazole derivatives VIII undergone firstly by reacting aromatic aldehydes I with (methoxymethyl)triphenyl phosphonium chloride to prepare the corresponding arylsubstitued enol ether derivatives VI using Wittig reaction described by Iwao et. al. ( J. Org. Chem.  2009, 74, 8143). Secondly, a cyclisation was perfomed with the enol ether VI, thiourea derivatives VII and N-bromosuccinimide (NBS) using the method of Zhao et. al. ( Tetrahedron Lett.,  2001, 42, 2101).

     Examples of Compound Synthesis 
     The invention will be more fully understood by reference to the following preparative examples, but they should not be construed as limiting the scope of the invention. 
     General: All chemicals used were commercial reagent grade products. Solvents were of anhydrous commercial grade and were used without further purification. The progress of the reactions was monitored by thin layer chromatography using precoated silica gel 60F 254, Merck TLC plates, which were visualized under UV light. Multiplicities in  1 H NMR spectra are indicated as singlet (s), broad singlet (br s), doublet (d), triplet (t), quadruplet (q), and multiplet (m) and the NMR spectrum were performed either on a Bruker Avance 300, 360 or 400 MHz spectrometer. Mass spectra were performed by Electrospray Ionisation Mass Spectrometry (ESI MS) in positive mode or by Atmospheric Pressure Chemical Ionization Mass Spectrometry (APCI MS) in positive mode. 
     LCMS methods: Method 1: This method was run on a Ultra-high performance liquid chromatography (UPLC) ACQUITY Waters instrument coupled to a TQD mass spectrometer. The gradient used was: starting at t=0.0 min with 5% of CH 3 CN+0.1% Formic acid in Water+0.1% Formic acid until t=0.5 min; then a linear gradient from t=0.5 min to t=7.0 min reaching 100% CH 3 CN+0.1% Formic acid; then staying at this state from t=7.0 min until t=10.0 min. The column used was a Waters HSS C18 1.8 μm, 2.1×50 mm. The detection instrument used was the triple quadrupole mass spectrometer (TQD) using ESI positive mode. 
     Method 2: This method was run on HPLC 2695 Alliance, Waters coupled to a ZMD mass spectrometer instrument. The gradient used was: starting at t=0.0 min with 0% of CH 3 CN+0.04% Formic acid in water (10 mM); then a linear gradient to t=3.1 min reaching 100% of CH 3 CN+0.04% Formic acid; then staying at this state to t=3.8 min and decreasing to =4.8 min to 0% of CH 3 CN+0.04% Formic acid in water. The column used was a Sunfire 2.1×50 mm dp: 3.5 μm.

     In another embodiment, the invention relates to a pharmaceutical composition comprising a compound as depicted above. 
     Such a pharmaceutical composition can be adapted for oral administration, and can be formulated using pharmaceutically acceptable carriers well known in the art in suitable dosages. Such carriers enable the pharmaceutical compositions to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions, and the like, for ingestion by the patient. In addition to the active ingredients, these pharmaceutical compositions may contain suitable pharmaceutically-acceptable carriers comprising excipients and auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically. Further details on techniques for formulation and administration may be found in the latest edition of Remington&#39;s Pharmaceutical Sciences (Maack Publishing Co., Easton, Pa.). 
     The composition of the invention can also take the form of a pharmaceutical or cosmetic composition for topical administration. 
     Such compositions may be presented in the form of a gel, paste, ointment, cream, lotion, liquid suspension aqueous, aqueous-alcoholic or, oily solutions, or dispersions of the lotion or serum type, or anhydrous or lipophilic gels, or emulsions of liquid or semi-solid consistency of the milk type, obtained by dispersing a fatty phase in an aqueous phase or vice versa, or of suspensions or emulsions of soft, semi-solid consistency of the cream or gel type, or alternatively of microemulsions, of microcapsules, of microparticles or of vesicular dispersions to the ionic and/or nonionic type. These compositions are prepared according to standard methods. 
     The composition according to the invention comprises any ingredient commonly used in dermatology and cosmetic. It may comprise at least one ingredient selected from hydrophilic or lipophilic gelling agents, hydrophilic or lipophilic active agents, preservatives, emollients, viscosity enhancing polymers, humectants, surfactants, preservatives, antioxidants, solvents, and fillers, antioxidants, solvents, perfumes, fillers, screening agents, bactericides, odor absorbers and coloring matter. 
     As oils which can be used in the invention, mineral oils (liquid paraffin), vegetable oils (liquid fraction of shea butter, sunflower oil), animal oils, synthetic oils, silicone oils (cyclomethicone) and fluorinated oils may be mentioned. Fatty alcohols, fatty acids (stearic acid) and waxes (paraffin, carnauba, beeswax) may also be used as fatty substances. 
     As emulsifiers, glycerols, polysorbates, glycerides, and PEGs can be used in the invention. 
     As hydrophilic gelling agents, carboxyvinyl polymers (carbomer), acrylic copolymers such as acrylate/alkylacrylate copolymers, polyacrylamides, polysaccharides such as hydroxypropylcellulose, clays and natural gums may be mentioned, and as lipophilic gelling agents, modified clays such as bentones, metal salts of fatty acids such as aluminum stearates and hydrophobic silica, or alternatively ethylcellulose and polyethylene may be mentioned. 
     As hydrophilic active agents, proteins or protein hydrolysates, amino acids, polyols, urea, allantoin, sugars and sugar derivatives, vitamins, starch and plant extracts, in particular those of Aloe vera may be used. 
     As lipophilic active, agents, retinol (vitamin A) and its derivatives, tocopherol (vitamin E) and its derivatives, essential fatty acids, ceramides and essential oils may be used. These agents add extra moisturizing or skin softening features when utilized. 
     In addition, a surfactant can be included in the composition so as to provide deeper penetration of the compound capable of depleting mast cells, such as a tyrosine kinase inhibitor, preferably a c-kit inhibitor. 
     Among the contemplated ingredients, the invention embraces penetration enhancing agents selected for example from the group consisting of mineral oil, water, ethanol, triacetin, glycerin and propylene glycol; cohesion agents selected for example from the group consisting of polyisobutylene, polyvinyl acetate and polyvinyl alcohol, and thickening agents. 
     Chemical methods of enhancing topical absorption of drugs are well known in the art. For example, compounds with penetration enhancing properties include sodium lauryl sulfate (Dugard, P. H. and Sheuplein, R. J., “Effects of Ionic Surfactants on the Permeability of Human Epidermis An Electrometric Study,” J. West. Dermatol., V.60, pp. 263-69, 1973), lauryl amine oxide (Johnson et. al., U.S. Pat. No. 4,411,893), azone (Rajadhyaksha, U.S. Pat. Nos. 4,405,616 and 3,989,816) and decylmethyl sulfoxide (Sekura, D. L. and Scala, J., “The Percutaneous Absorption of Alkylmethyl Sulfides,” Pharmacology of the Skin, Advances In Biolocy of Skin, (Appleton-Century Craft) V. 12, pp. 257-69, 1972). It has been observed that increasing the polarity of the head group in amphoteric molecules increases their penetration-enhancing properties but at the expense of increasing their skin irritating properties (Cooper, E. R. and Berner, B., “Interaction of Surfactants with Epidermal Tissues: Physiochemical Aspects,” Surfactant Science Series, V. 16, Reiger, M. M. ed. (Marcel Dekker, Inc.) pp. 195-210, 1987). 
     A second class of chemical enhancers are generally referred to as co-solvents. These materials are absorbed topically relatively easily, and, by a variety of mechanisms, achieve permeation enhancement for some drugs. Ethanol (Gale et. al., U.S. Pat. No. 4,615,699 and Campbell et. al., U.S. Pat. Nos. 4,460,372 and 4,379,454), dimethyl sulfoxide (U.S. Pat. Nos. 3,740,420 and 3,743,727, and U.S. Pat. No. 4,575,515), and glycerine derivatives (U.S. Pat. No. 4,322,433) are a few examples of compounds which have shown an ability to enhance the absorption of various compounds. 
     The pharmaceutical compositions of the invention can also be intended for administration as an aerosolized formulation to target areas of a patient&#39;s respiratory tract. 
     Devices and methodologies for delivering aerosolized bursts of a formulation of a drug is disclosed in U.S. Pat. No. 5,906,202. Formulations are preferably solutions, e.g. aqueous solutions, ethanoic solutions, aqueous/ethanoic solutions, saline solutions, colloidal suspensions and microcrystalline suspensions. For example aerosolized particles comprise the active ingredient mentioned above and a carrier, (e.g., a pharmaceutically active respiratory drug and carrier) which are formed upon forcing the formulation through a nozzle which nozzle is preferably in the form of a flexible porous membrane. The particles have a size which is sufficiently small such that when the particles are formed they remain suspended in the air for a sufficient amount of time such that the patient can inhale the particles into the patient&#39;s lungs. 
     The invention encompasses the systems described in U.S. Pat. No. 5,556,611:
         liquid gas systems (a liquefied gas is used as propellent gas (e.g. low-boiling FCHC or propane, butane) in a pressure container,   suspension aerosol (the active substance particles are suspended in solid form in the liquid propellent phase),   pressurized gas system (a compressed gas such as nitrogen, carbon dioxide, dinitrogen monoxide, air is used.       

     Thus, according to the invention the pharmaceutical preparation is made in that the active substance is dissolved or dispersed in a suitable nontoxic medium and said solution or dispersion atomized to an aerosol, i.e. distributed extremely finely in a carrier gas. This is technically possible for example in the form of aerosol propellent gas packs, pump aerosols or other devices known per se for liquid misting and solid atomizing which in particular permit an exact individual dosage. 
     Therefore, the invention is also directed to aerosol devices comprising the compound as defined above and such a formulation, preferably with metered dose valves. 
     The pharmaceutical compositions of the invention can also be intended for intranasal administration. 
     In this regard, pharmaceutically acceptable carriers for administering the compound to the nasal mucosal surfaces will be readily appreciated by the ordinary artisan. These carriers are described in the Remington&#39;s Pharmaceutical Sciences” 16th edition, 1980, Ed. By Arthur Osol, the disclosure of which is incorporated herein by reference. 
     The selection of appropriate carriers depends upon the particular type of administration that is contemplated. For administration via the upper respiratory tract, the composition can be formulated into a solution, e.g., water or isotonic saline, buffered or unbuffered, or as a suspension, for intranasal administration as drops or as a spray. Preferably, such solutions or suspensions are isotonic relative to nasal secretions and of about the same pH, ranging e.g., from about pH 4.0 to about pH 7.4 or, from pH 6.0 to pH 7.0. Buffers should be physiologically compatible and include, simply by way of example, phosphate buffers. For example, a representative nasal decongestant is described as being buffered to a pH of about 6.2 (Remington&#39;s, Id. at page 1445). Of course, the ordinary artisan can readily determine a suitable saline content and pH for an innocuous aqueous carrier for nasal and/or upper respiratory administration. 
     Common intranasal carriers include nasal gels, creams, pastes or ointments with a viscosity of, e.g., from about 10 to about 3000 cps, or from about 2500 to 6500 cps, or greater, may also be used to provide a more sustained contact with the nasal mucosal surfaces. Such carrier viscous formulations may be based upon, simply by way of example, alkylcelluloses and/or other biocompatible carriers of high viscosity well known to the art (see e.g., Remington&#39;s, cited supra. A preferred alkylcellulose is, e.g., methylcellulose in a concentration ranging from about 5 to about 1000 or more mg per 100 ml of carrier. A more preferred concentration of methyl cellulose is, simply by way of example, from about 25 to about mg per 100 ml of carrier. 
     Other ingredients, such as art known preservatives, colorants, lubricating or viscous mineral or vegetable oils, perfumes, natural or synthetic plant extracts such as aromatic oils, and humectants and viscosity enhancers such as, e.g., glycerol, can also be included to provide additional viscosity, moisture retention and a pleasant texture and odor for the formulation. For nasal administration of solutions or suspensions according to the invention, various devices are available in the art for the generation of drops, droplets and sprays. 
     A premeasured unit dosage dispenser including a dropper or spray device containing a solution or suspension for delivery as drops or as a spray is prepared containing one or more doses of the drug to be administered and is another object of the invention. The invention also includes a kit containing one or more unit dehydrated doses of the compound, together with any required salts and/or buffer agents, preservatives, colorants and the like, ready for preparation of a solution or suspension by the addition of a suitable amount of water. 
     Another aspect of the invention is directed to the use of said compound to manufacture a medicament. In other words, the invention embraces a method for treating a disease related to unregulated c-kit transduction comprising administering an effective amount of a compound as defined above to a mammal in need of such treatment. 
     More particularly, the invention is aimed at a method for treating a disease selected from autoimmune diseases, allergic diseases, bone loss, cancers such as leukemia and GIST, tumor angiogenesis, inflammatory diseases, inflammatory bowel diseases (IBD), interstitial cystitis, mastocytosis, infections diseases, metabolic disorders, fibrosis, diabetes and CNS disorders comprising administering an effective amount a compound depicted above to a mammal in need of such treatment. 
     The above described compounds are useful for manufacturing a medicament for the treatment of diseases related to unregulated c-kit transduction, including, but not limited to:
         neoplastic diseases such as mastocytosis, canine mastocytoma, solid tumours, human gastrointestinal stromal tumor (“GIST”), small cell lung cancer, non-small cell lung cancer, acute myelocytic leukemia, acute lymphocytic leukemia, myelodysplastic syndrome, chronic myelogenous leukemia, colorectal carcinomas, gastric carcinomas, gastrointestinal stromal tumors, testicular cancers, glioblastomas, solid tumors and astrocytomas.   tumor angiogenesis.   metabolic diseases such as diabetes mellitus and its chronic complications; obesity; diabete type II; hyperlipidemias and dyslipidemias; atherosclerosis; hypertension; and cardiovascular disease.   allergic diseases such as asthma, allergic rhinitis, allergic sinusitis, anaphylactic syndrome, urticaria, angioedema, atopic dermatitis, allergic contact dermatitis, erythema nodosum, erythema multiforme, cutaneous necrotizing venulitis and insect bite skin inflammation and blood sucking parasitic infestation.   interstitial cystitis.   bone loss (osteoporosis).   inflammatory diseases such as rheumatoid arthritis, conjunctivitis, rheumatoid spondylitis, osteoarthritis, gouty arthritis and other arthritic conditions.   autoimmune diseases such as multiple sclerosis, psoriasis, intestine inflammatory disease, ulcerative colitis, Crohn&#39;s disease, rheumatoid arthritis and polyarthritis, local and systemic scleroderma, systemic lupus erythematosus, discoid lupus erythematosus, cutaneous lupus, dermatomyositis, polymyositis, Sjogren&#39;s syndrome, nodular panarteritis, autoimmune enteropathy, as well as proliferative glomerulonephritis.   graft-versus-host disease or graft rejection in any organ transplantation including kidney, pancreas, liver, heart, lung, and bone marrow.   Other autoimmune diseases embraced by the invention active chronic hepatitis and chronic fatigue syndrome.   subepidermal blistering disorders such as pemphigus.   Vasculitis.   HIV infection.   melanocyte dysfunction associated diseases such as hypermelanosis resulting from melanocyte dysfunction and including lentigines, solar and senile lentigo, Dubreuilh melanosis, moles as well as malignant melanomas. In this regard, the invention embraces the use of the compounds defined above to manufacture a medicament or a cosmetic composition for whitening human skin.   CNS disorders such as psychiatric disorders, migraine, pain, memory loss and nerve cells degeneracy. More particularly, the method according to the invention is useful for the treatment of the following disorders: Depression including dysthymic disorder, cyclothymic disorder, bipolar depression, severe or “melancholic” depression, atypical depression, refractory depression, seasonal depression, anorexia, bulimia, premenstrual syndrome, post-menopause syndrome, other syndromes such as mental slowing and loss of concentration, pessimistic worry, agitation, self-deprecation, decreased libido, pain including, acute pain, postoperative pain, chronic pain, nociceptive pain, cancer pain, neuropathic pain, psychogenic pain syndromes, anxiety disorders including anxiety associated with hyperventilation and cardiac arrhythmias, phobic disorders, obsessive-compulsive disorder, posttraumatic stress disorder, acute stress disorder, generalized anxiety disorder, psychiatric emergencies such as panic attacks, including psychosis, delusional disorders, conversion disorders, phobias, mania, delirium, dissociative episodes including dissociative amnesia, dissociative fugue and dissociative identity disorder, depersonalization, catatonia, seizures, severe psychiatric emergencies including suicidal behaviour, self-neglect, violent or aggressive behaviour, trauma, borderline personality, and acute psychosis, schizophrenia including paranoid schizophrenia, disorganized schizophrenia, catatonic schizophrenia, and undifferentiated schizophrenia,   neurodegenerative diseases including Alzheimer&#39;s disease, Parkinson&#39;s disease, Huntington&#39;s disease, the prion diseases, Motor Neurone Disease (MND), and Amyotrophic Lateral Sclerosis (ALS).   substance use disorders as referred herein include but are not limited to drug addiction, drug abuse, drug habituation, drug dependence, withdrawal syndrome and overdose.   Cerebral ischemia.   Fibrosis.   Duchenne muscular dystrophy.       

     Regarding mastocytosis, the invention contemplates the use of the compounds as defined above for treating the different categories which can be classified as follows: 
     Category I is composed by two sub-categories (IA and IB). Category IA is made by diseases in which mast cell infiltration is strictly localized to the skin. This category represents the most frequent form of the disease and includes: i) urticaria pigmentosa, the most common form of cutaneous mastocytosis, particularly encountered in children, ii) diffuse cutaneous mastocytosis, iii) solitary mastocytoma and iv) some rare subtypes like bullous, erythrodermic and teleangiectatic mastocytosis. These forms are characterized by their excellent prognosis with spontaneous remissions in children and a very indolent course in adults. Long term survival of this form of disease is generally comparable to that of the normal population and the translation into another form of mastocytosis is rare. Category IB is represented by indolent systemic disease (SM) with or without cutaneous involvement. These forms are much more usual in adults than in children. The course of the disease is often indolent, but sometimes signs of aggressive or malignant mastocytosis can occur, leading to progressive impaired organ function. 
     Category II includes mastocytosis with an associated hematological disorder, such as a myeloproliferative or myelodysplastic syndrome, or acute leukemia. These malignant mastocytosis does not usually involve the skin. The progression of the disease depends generally on the type of associated hematological disorder that conditiones the prognosis. 
     Category III is represented by aggressive systemic mastocytosis in which massive infiltration of multiple organs by abnormal mast cells is common. In patients who pursue this kind of aggressive clinical course, peripheral blood features suggestive of a myeloproliferative disorder are more prominent. The progression of the disease can be very rapid, similar to acute leukemia, or some patients can show a longer survival time. 
     Finally, category IV of mastocytosis includes the mast cell leukemia, characterized by the presence of circulating mast cells and mast cell progenitors representing more than 10% of the white blood cells. This entity represents probably the rarest type of leukemia in humans, and has a very poor prognosis, similar to the rapidly progressing variant of malignant mastocytosis. Mast cell leukemia can occur either de novo or as the terminal phase of urticaria pigmentosa or systemic mastocytosis. 
     The invention also contemplates the method as depicted for the treatment of recurrent bacterial infections, resurging infections after asymptomatic periods such as bacterial cystitis. More particularly, the invention can be practiced for treating FimH expressing bacteria infections such as Gram-negative enterobacteria including  E. coli, Klebsiella pneumoniae, Serratia marcescens, Citrobactor freudii  and  Salmonella typhimurium.    
     In this method for treating bacterial infection, separate, sequential or concomitant administration of at least one antibiotic selected bacitracin, the cephalosporins, the penicillins, the aminoglycosides, the tetracyclines, the streptomycins and the macrolide antibiotics such as erythromycin; the fluoroquinolones, actinomycin, the sulfonamides and trimethoprim, is of interest.

     Examples of in vitro TK Inhibition Assays 
     Procedures C-Kit WT and Mutated C-Kit (D816V) Assay 
     Proliferation Assays 
     Colorimetric cell proliferation and viability assay (reagent CellTiter-Blue purchased from Promega cat No G8081) was performed on BaF3 Kit WT or Kit D816 cell lines as well as on human and murine mastocytoma and mast leukemia cell lines. 
     A total of 2.9 10 4  cells/50 μ 1  were seeded per well of a 96-wells plate. Treatment was initiated by addition of a 2× drug solution of ½ serial dilutions ranging from 0 to 10 μM. After incubating for 48 hours at 37° C., 10 μl of a ½ dilution of CellTiter-Blue reagent was added to each well and the plates were returned to the incubator for an additional 4 hours. 
     The fluorescence intensity from the CellTiter-Blue reagent is proportional to the number of viable cells and data were recorded (544 Ex /590 Em ) using a POLARstar OMEGA microplate reader (BMG LabteckSarl). A background control without cells was used as a blank. The positive control of the assay corresponds to the cell proliferation obtained in the absence of drug treatment (100% proliferation). Each sample was done in triplicate. The results were expressed as a percentage of the proliferation obtained in absence of treatment. 
     All drugs were prepared as 20 mM stock solutions in DMSO and conserved at −80° C. Drug dilutions were made fresh in medium before each experiment. A DMSO control was included in each experiment. 
     -Cells 
     Human Kit WT and human Kit D816V are derived from the murine IL-3 dependent Ba/F3 proB lymphoid cells. While Ba/F3 Kit WT are stimulated with 250 ng/ml of recombinant murine SCF, cells expressing Kit D816V are independent of cytokines for their growth. The FMA3 and P815 cell lines are mastocytoma cells expressing endogenous mutated forms of Kit, i.e., frame deletion in the murine juxtamembrane coding region of the receptor-codons 573 to 579 (FMA3) and activating D814Y mutation in the kinase domain (P815). The human leukaemic MC line HMC-1 expresses two single point mutations in the c-Kit gene, V560G in the juxtamembrane domain and D816V in the kinase domain. 
     -Immunoprecipitation Assays and Western Blotting Analysis: 
     For each assay, 5·10 6  Ba/F3 cells and Ba/F3-derived cells expressing various c-kit mutations were lysed and immunoprecipitated as described (Beslu et al., 1996). Briefly, cell lysates were immunoprecipitated using rabbit immunsera directed toward the cytoplasmic domain of either anti murine KIT (Rottapel et al., 1991) or anti human KIT (Santa Cruz). Western blot was hybridized with the 4G10 anti-phosphotyrosine antibody (UBI), the corresponding rabbit immunsera anti KIT or antibodies directed against signaling molecules. The membrane was then incubated either with HRP-conjugated goat anti mouse IgG antibody or with HRP-conjugated goat anti rabbit IgG antibody (Immunotech), Proteins of interest were then visualized by incubation with ECL reagent (Amersham).
