A series of novel pyrrolidinyl linker TRPV1 antagonists were prepared in an effort to lower the hyperthermic side-effects of first-generation antagonist BCTC. These compounds were investigated for antagonism of hTRPV1 activation by capsaicin and acid in vitro. Preliminary results suggested the compounds 10a, 10b, 10c and 10j had favorable TRPV1 antagonism activity. In further studies in vivo, 10b, comparable to BCTC, showed potent analgesic activity in capsaicin-induced and heat-induced pain models. In addition, 10b indicated a reduced risk of body temperature elevation. All of these demonstrated that 10b can be considered as a safe candidate for the further development of analgesic drugs.
