Abstract

A novel series of 4, 5-biarylimidazoles as TRPV1 antagonists were designed based on the previously reported 4, 6-disubstituted benzimidazole series. The analogs were evaluated for their ability to block capsaicin-or acid-induced calcium influx in TRPV1-expressing CHO cells. These studies led to the identification of a highly potent and orally bioavailable TRPV1 antagonist, imidazole 33.
