Description:
IMIDAZOLE AND THEIR USE AS CCK-1 RECEPTOR MODULATORS This invention relates to CCK-1 receptor modulators for the treatment of gastrointestinal and CNS disorders. More particularly, this invention relates to certain imidazole compounds useful as selective agonists or antagonists of the CCK-1 receptor.

BACKGROUND OF THE INVENTION Cholecystokinin (CCK) is a brain-gut peptide hormone located both in the gastrointestinal system and in the central nervous system. The actions of CCK are mediated by two G-protein coupled receptors: CCK-1 (formerly CCK- A) and CCK-2 (formerly CCK-B/gastrin). These CCK receptors are expressed throughout the gastrointestinal system and in different parts of the central nervous system including the cortex, the striatum, the hypothalamus, the hippocampus, the olfactory bulb, the vagal afferent neurones, in different enteric nerves, and in the genital tract.

CCK has a number of biological actions. CCK is the primary hormonal regulator of gall bladder contraction in response to a meal. CCK stimulates pancreatic and biliary secretions and regulates Gl motility and specifically gut and colonic motility. CCK promotes protein synthesis and cell growth, especially in the GI system and in the pancreas. CCK is involved in mediating satiety after a meal. CCK is an important neuromodulator and neurotransmitter involved in anxiety and panic disorder. CCK modulates the release of dopamine. CCK is also known to antagonize morphine and beta-endorphine induced analgesia and the action on nociception. A review of CCK receptors, ligands and the activities thereof may be found in P. de Tullio et al., Exp. Opin.

Invest. Drugs 2000,9 (1) : 129-146.

A number of CCK-1 receptor antagonists are presently in clinical trials including, tarazepide, devazepide and lintitript. Phase III equivalent trials are in progress by Rotta Research Group and Forest Laboratories on dexloxiglumide, a CCK-1 antagonist for the treatment of constipation, irritable bowel syndrome and non-ulcer dyspepsia.

dexloxiglumide Also, Kaken Pharmaceuticals and-Mitsubishi-Tokyo Pharmaceuticals are awaiting registration in Japan on loxiglumide, a CCK-1 receptor antagonist for the treatment of GI cancers and pancreatitis. Loxiglumide is the racemate of dexloxiglumide.

A number of CCK-1 receptor agonists are under preclinical investigation.

Glaxo Smith Kline, Inc. is investigating GW 5823, GW 7854, GW 7178 and GW 8573, 1,5-benzodiaepines for the treatment of gallstones, gastrointestinal disease and obesity.

GW 7178 GW 5823 GW 7854 Also, Pfizer is investigating the CCK-1 receptor agonist, PD 170292, for obesity.

In Patent application WO 01/66539 there are disclosed certain imidazoles for the inhibition of raf kinases for the treatment of cancers of the general formula :

These compounds are not taught as inhibitors of CCK receptors.

Applicants have now discovered that certain imidazoles as described below are useful CCK-1 receptor modulators, agonists and antagonists, and most particularly antagonists. As such, these compounds are useful to treat a number of disease states mediated by CCK.

The features and advantages of the invention are apparent to one of ordinary skill in the art. Based on this disclosure, including the summary, detailed description, background, examples, and claims, one of ordinary skill in the art will be able to make modifications and adaptations to various conditions and usages. Publications described herein are incorporated by reference in their entirety.

The compounds as described above may be made according to processes within the skill of the art and/or that are described in the schemes and examples that follow. To obtain the various compounds herein, starting materials may be employed that carry the ultimately desired substituents though the reaction scheme with or without protection as appropriate.

Alternatively, it may be necessary to employ, in the place of the ultimately desired substituent, a suitable group that may be carried through the reaction scheme and replaced as appropriate with the desired substituent. the compounds as described above may be made according to Schemes A-F below. Persons skilled in the art will recognize that certain compounds are more advantageously produced by one scheme as compared to the other.

The Grignard reagent A1 can be purchased or synthesized from the corresponding arylmethyl bromide. Certain substituents on R1 that are

incompatible with the reaction conditions required to form A1 may require protection. Oxidation of alcohol A3 can be accomplished using a variety of conditions including Dess-Martin oxidation or Swern oxidation conditions.

Diketone A5 can optionally be obtained by the method described in Scheme B or the diketone can be obtained from commercial sources. The synthesis of imidazole A6 using HMTA (hexamethylene-tetramine) can also be accomplished with formaldehyde and NH40Ac. The protection (SEM) of imidazole A6 can also be accomplished with alternate protecting groups such as MEM, MOM, or benzyl. Arylacetic acids used to make A8 can be obtained from commercial sources or made by methods described by Z. Wang et al.

(Synth. Commun. 1999,29 : 2361-2364), or T. Saito et al. (J. Am. Chem. Soc. 1998,120 : 11633-11644). The condensation of A7 with arylacetic acids results in a mixture of olefin isomers A8 (E) and A8 (Z). These isomers can typically be separated and isolated using chromatographic methods. Additionally, pure isomers A8 (E) and A8 (Z) can be isomerized to mixtures using photolysis and further separated by chromatographic methods. Reduction of A8 to A9 can be accomplished using TsNHNH2 to produce a racemic mixture of acid A9. This mixture of optical isomers can be separated by chiral chromatographic methods. Alternatively, the reduction can be accomplished using catalytic hydrogenation methods or transfer hydrogenation methods.

SCHEME B R1-I KMn04 R1 O R2-H-R2-. R1 Sonogashira Coupling B1 Referring to Scheme B, there are disclosed the following notes and additions. Scheme B shows an alternative to the synthesis of diketone A5, which is then used in Scheme A to synthesize the desired products. Alkyne B1 can be obtained from commercial sources or synthesized by standard synthetic methods, such as coupling of trimethylsilylacetylene with an aryl bromide or iodide using a Sonogashira reaction, or by homologation of an aryl aldehyde using (EtO) 2P (O) C (N2) C (O) CH3.

Referring to Scheme C, there are disclosed the following notes and additions. The starting acid can come from A9, F2, or when appropriate the imidazole can be protected at the R3 position with a protecting group such as SEM. Of course, analogous acid A8 can be used to produce analogous C4 or C5. The reduction to C1 may be effected with a number of reducing agents including DIBAL-H and LAH. The oxidation reaction producing C2 may be carried out using Swern or Dess-Martin conditions. One carbon homologation to C3 is accomplished by a Wittig reaction using (methoxymethyl) triphenyl- phosphonium bromide and base, followed by oxidation to the acid C4.

Alternatively the two carbon homologated acids C5 can be obtained by Horner-Emmons reaction, using (EtO) 2P (O) CH2CO2Et to provide the acrylate, followed by reduction of the double bond by hydrogenation, and hydrolysis of the ester using a base such as LiOH.

The olefin in D2 can be cleaved under ozonolysis conditions or with an osmium tetroxide/sodium periodate protocol to provide aldehyde D3. Condensation of the aldehyde D3 with benzoin A5 then affords esters of type D4. Hydrolysis with LiOH or another suitable base then affords the acid A9.

SCHEME E

Referring to Scheme E, there are disclosed the following notes and additions. As shown, any of the acids A9, C4, C5, or F2, can be employed as a starting material. Of course, analogous acid A8 can be used to produce analogous E1. Alternatively, ester D4 might also be employed where Me3AI is used as a Lewis Acid with NHR6R7. Amines can be obtained from commercial

sources or synthesized by known synthetic methods. Additionally, the amide bond formation can be accomplished by any number of known peptide coupling methods including DIC/DMAP or DCC. In some cases protection of the imidazole at the R3 position with SEM or some other protecting group may be required.

Of course, analogous acid A8 can be used to produce analogous F1 or F2. Alkyl halides would preferably be commercial or synthesized bromides or iodides, but in some cases alkyl chlorides could be used. Hydrolysis of ester F1 can be accomplished as described in Scheme D to provide the desired acid F2.

Assay Method Cell Culture CHO-K1 cells that had undergone stable transfection with the CCK-1 receptor were grown in DMEM supplemented with L-glutamine (2 mM), penicillin (50 units/mL) and streptomycin (50 Rg/mL). Cells were cultured'under continuous G418 selection (2 mM) and were harvested using a rubber cell scraper.

CHO-K1 cells were sub-cultured a maximum of ten times before being reseeded from the original stocks.

Membrane Preparation Membranes were prepared from the stably transfected CHO-K1 cells. Frozen cell pellets (-40 °C) were thawed in 14 mL of buffer A (10 mM HEPES, 130 mM NaCI, 4.7 mM KCl, 5 mM MgCI, 1 mM EGTA and 15.4 mg/100 mL bacitracin at pH 7.2), adapted from Harper et al. (Br. J. Pharmacol. 1996, 118 : 1717-1726). The thawed pellets were homogenized using a Poltron PT- 10 (7 X 1 s). The homogenates were centrifuged for 5 min at 1500 rpm (600 X g), and the resulting pellets were discarded. The supernatants were re- centrifuged in order to collect the receptor-membrane pellets (25 min 15,000 rpm; 39,800 X g), which were re-suspended in buffer A.

Incubation Conditions All assays were conducted in 96-well plates (GF/B millipore filter plates) using buffer A, with 0. 3, uM PD-134, 308, for the dilutions. The CCK-2 receptor ligand was included to eliminate the contribution of this receptor subtype to the binding. For the optimal cell number determination experiments 20 pM [1251]-BH-CCK-8S (50 uL 60 pM solution) was incubated with a range of cell concentrations (2.5 X105 to 12.5 X 105 cells/well) in a total volume of 150 µL.

Total binding of [1251]-BH-CCK-8S was determined in the presence of 15 gL of buffer A. Non-specific binding of [1251]-BH-CCK-8S was determined in the presence of 15) iL of 100, uM 2-naphthalenesulphonyl L-aspartyl-(2- phenethyl) amide (2-NAP: see R. A. Hull et al. Br. J. Pharmacol. 1993,108 : 734- 740), a CCK-1 receptor selective antagonist that is structurally unrelated to the

radioligand [1251]-BH-CCK-8S. The assay preparation was incubated for 1 h at 213 OC, and then the assay was terminated upon rapid filtration of the preparation under reduced pressure. The loaded filters were washed three times using undiluted PBS (100 gel), and then the residues were transferred to 5 mL scintillation tubes. Bound radioactivity was determined using a gamma counter (count time = 1 min). From these experiments a cell concentration of 1 pellet in 40 mL of buffer (2.5 X 106 cells/mL) was chosen for use in other assays (below). To validate the radioligand concentration and incubation time for the assay, saturation and kinetic binding studies were also conducted (see M. F. Morton, The Pharmacological Characterization of Cholecystokinin Receptors in the Human Gastrointestinal Tract. PhD Thesis, University of London, 2000). The affinity of novel compounds was estimated by incubating membrane preparations with 15 iL of competing ligand (0.1 pM-1 mM) for 60 min at 21 +3 °C. The assay was then terminated according to the procedure outlined above.

Data Analysis The pKi values were determined using the equation of Y. -C. Cheng and W. H.

Prusoff (Biochem. Pharmacol. 1973,22 (23): 3099-3108): To circumvent problems associated with computer-assisted data analysis of compounds with low affinity, the data obtained in the current study were weighted according to a method described by Morton (2000). In brief, 100% and 0% specific binding were defined independently using total. binding and binding obtained in the presence of a high concentration of the reference antagonist, 2-NAP.
