Discovery of 1-(1H-indazol-4-yl)-3-((1-phenyl-1H-pyrazol-5-yl)methyl) ureas as potent and thermoneutral TRPV1 antagonists
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) = 0.4-0.5 nM. Further, in vivo studies in mice indicated that these derivatives both antagonized capsaicin induced hypothermia, consistent with their in vitro activity, and themselves did not induce hyperthermia. In the formalin model, 51 showed antinociceptive activity in a dose-dependent manner.
