Abstract

A 28-membered 1,2,3-triazolyl salicylamide library was synthesized via a Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition and evaluated for their abilities to inhibit NO production in LPS-activated RAW264.7 macrophage cells. Among 28 analogues, 29 g showed a significant inhibitory activity (IC(50) = 12.8 μM). The inhibitory effects of 29 g on LPS-mediated NO production in macrophage cells appeared to be associated with the suppression of iNOS expression.
