Abstract

Pirfenidone, a pyridone compound, is an effective and novel antifibrotic agent. In this article, we describe the design, synthesis and activity evaluation of novel antifibrotic agents, 1-(substituted aryl)-5-trifluoromethyl-2(1H) pyridones modified with carbohydrate. Most of the title compounds exhibited comparable or better inhibitory activity than fluorofenidone. Notably, compound 19a demonstrated the highest cell-based inhibitory activity against NIH 3T3 (IC50 = 0.17 mM).
Keywords: antifibrotic; pirfenidone; fluorofenidone; carbohydrate modified; glucose antifibrotic; pirfenidone; fluorofenidone; carbohydrate modified; glucose
