Abstract

Structure-activity relationship (SAR) efforts around our initial lead compound 1 led to the identification of potent P2X(7) receptor antagonists with improved pharmacokinetic profiles. These compounds were potent and selective at the P2X(7) receptor in both human and rodent. Compound (entry 31) exhibited oral efficacy in the rat MIA and CCI pain models.
