Pyrazole Urea-Based Inhibitors of p38 MAP Kinase: From Lead Compound to Clinical Candidate
摘要:
We report on a series of N-pyrazole, N'-aryl ureas and their mode of binding to p38 mitogen activated protein kinase. Importantly, a key binding domain that is distinct from the adenosine 5'-triphoshate (ATP) binding site is exposed when the conserved activation loop, consisting in part of Asp168-Phe169-Gly170, adopts a conformation permitting lipophilic and hydrogen bonding interactions between this class of inhibitors and the protein. We describe the correlation of the structure-activity relationships and crystallographic structures of these inhibitors with p38. In addition, we incorporated another binding pharmacophore that forms a hydrogen bond at the ATP binding site. This modification affords significant improvements in binding, cellular, and in vivo potencies resulting in the selection of 45 (BIRB 796) as a clinical candidate for the treatment of inflammatory diseases.

A series of 1-indazol-3-(1-phenylpyrazol-5-yl)methyl ureas were investigated as hTRPV1 antagonists. The structure-activity relationship study was conducted systematically for both the indazole A-region and the 3-trifluoromethyl/t-butyl pyrazole C-region to optimize the antagonism toward the activation by capsaicin. Among them, the antagonists 26, 50 and 51 displayed highly potent antagonism with Ki(CAP)
An object of the present invention is to provide a drug containing a compound having Trk-inhibiting activity as an active ingredient in prophylaxis and/or therapy of diseases such as pain, pruritus, lower urinary tract dysfunction, asthma, allergic rhinitis, inflammatory bowel disease or Chagas disease. A compound represented by the general formula (I):
(wherein all symbols represent the same meanings as described in the specification), a salt thereof, an N-oxide thereof, a solvate thereof or a prodrug thereof is useful as a drug component having Trk-inhibiting activity in prophylaxis and/or therapy of diseases such as pain, pruritus, lower urinary tract dysfunction, asthma, allergic rhinitis, inflammatory bowel disease or Chagas disease.
