Synthesis and SAR of heteroaryl-phenyl-substituted pyrazole derivatives as highly selective and potent canine COX-2 inhibitors

Bioorg Med Chem Lett. 2006 Apr 15;16(8):2076-80. doi: 10.1016/j.bmcl.2006.01.059. Epub 2006 Feb 7.

Abstract

The discovery of heteroaryl-phenyl-substituted pyrazole derivatives as canine selective COX-2 inhibitors is described. Structure-activity relationship (SAR) studies of this class of compounds led to the identification of compound 1 which demonstrated a canine whole blood COX-2 inhibitory IC50 of 12 nM and selectivity ratio of COX-1/COX-2 greater than 4000-fold.
