Discovery and optimization of a novel series of pyrazolyltetrahydropyran N-type calcium channel (Cav 2.2) blockers for the treatment of pain
摘要:
A novel series of pyrazolyltetrahydropyran N-type calcium channel blockers are described. Structural modifications of the series led to potent compounds in both a cell-based fluorescent calcium influx assay and a patch clamp electrophysiology assay. Representative compounds from the series were bioavailable and showed efficacy in the rat CFA and CCI models of inflammatory and neuropathic pain.
