Abstract

Optimization of a water soluble, moderately potent lead series of isoxazole-3-carboxamides was conducted, affording a compound with the requisite balance of potency, solubility and physicochemical properties for in vivo use. Compound 8e was demonstrated to be efficacious in a rat model of inflammatory pain, following oral administration.
