摘要

Two series of celecoxib analogues having 1, 5-diaryl relationship were synthesized. The key strategy of the molecular design was oriented towards exploring bioisosteric modifications of the sulfonamide moiety of celecoxib. First series (2a–2i) of celecoxib analogues bearing cyano functionality in place of sulfonamide moiety was synthesized by the reaction of appropriate trifluoromethyl-β-diketones (5a–5i) with 4-hydrazinylbenzonitrile ...
