A series of novel pyrrolidinyl linker TRPV 1 antagonists were prepared in an effort to lower the hyperthermic side‐effects of first‐generation antagonist BCTC . These compounds were investigated for antagonism of h TRPV 1 activation by capsaicin and acid in vitro . Preliminary results suggested the compounds 10a , 10b , 10c and 10j had favorable TRPV 1 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.
