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 anti-nociceptive activity in a dose-dependent manner.

Starting with our previously described20 class of CC chemokine receptor-3 (CCR3) antagonist, we improved the potency by replacing the phenyl linker of 1 with a cyclohexyl linker and by replacing the 4-benzylpiperidine with a 3-benzylpiperidine. The resulting compound, 32, is a potent and selective antagonist of CCR3. SAR studies showed that the 3-acetylphenyl urea of 32 could be replaced with heterocyclic ureas or heterocyclic-substituted phenyl ureas and still maintain the potency (inhibition of eotaxin-induced chemotaxis) of this class of compounds in the low-picomolar range (IC50 = 10-60 pM), representing some of the most potent CCR3 antagonists reported to date. The potency of 32 for mouse CCR3 (chemotaxis IC50 = 41 nM) and its oral bioavailability in mice (20% F) were adequate to assess the efficacy in animal models of allergic airway inflammation. Oral administration of 32 reduced eosinophil recruitment into the lungs in a dose-dependent manner in these animal models. On the basis of its overall potency, selectivity, efficacy, and safety profile, the benzenesulfonate salt of 32, designated DPC168, entered phase I clinical trials.
