Clinical candidate AMG 517 (1) is a potent antagonist toward multiple modes of activation of TRPV1; however, it suffers from poor solubility. Analogs with various substituents at the R region of 3 were prepared to improve the solubility while maintaining the potent TRPV1 activity of 1. Compounds were identified that maintained potency, had good pharmacokinetic properties, and improved solubility relative to 1.
