Abstract

Transient receptor potential vanilloid 3 (TRPV3) is a Ca(2+)- and Na(+)-permeable channel with a unique expression pattern. TRPV3 is found in both neuronal and non-neuronal tissues, including dorsal root ganglia, spinal cord, and keratinocytes. Recent studies suggest that TRPV3 may play a role in inflammation, pain sensation, and skin disorders. TRPV3 studies have been challenging, in part due to a lack of research tools such as selective antagonists. Herein, we provide the first detailed report on the development of potent and selective TRPV3 antagonists featuring a pyridinyl methanol moiety. Systematic optimization of pharmacological, physicochemical, and ADME properties of original lead 5a resulted in identification of a novel and selective TRPV3 antagonist 74a, which demonstrated a favorable preclinical profile in two different models of neuropathic pain as well as in a reserpine model of central pain.
