JNJ-17203212 is a transient receptor potential vanilloid 1 (TRPV1) antagonist (Ki = 72 nM for the recombinant guinea pig channel).1 It inhibits guinea pig TRPV1 channel activation induced by capsaicin (Item Nos. 92350 | 10010743) or pH decrease (IC50s = 58 and 470 nM, respectively). JNJ-17203212 (20 mg/kg) reduces the number of citric acid- or capsaicin-induced coughs in guinea pigs. It reduces spontaneous and palpitation-induced flinching and guarding in a mouse model of bone cancer pain when administered at a dose of 30 mg/kg.2 JNJ-17203212 decreases capsaicin-induced production of calcitonin gene-related peptide (CGRP) in a dose-dependent manner and inflammatory soup-induced trigeminal expression of cfos in rat models of migraine.3
