Abstract

The triaryl bis-sulfone 1 was modified by converting the aryl A-ring to a piperidine ring. The piperidine ring was further elaborated to a spirocyclopropyl piperidine moiety. The effect on CB2 binding potency, rat calcium channel affinity, and CYP 2C9 inhibition is described. ... A-ring replacements of 1 were investigated leading to compound 53 which had good affinity for the human CB2 receptor, reduced affinity for the rat calcium channel, and an improved cytochrome P450 ...
