- The natural product phloroglucinol-based derivatives representing monoacyl-, diacyl-, dimeric acyl-, alkylated monoacyl-, and the nitrogen-containing alkylated monoacylphloro- glucinols were synthesized and evaluated for inhibitory activities against the inflammatory mediators such as inducible nitric oxide synthase (iNOS) and nuclear factor kappaB (NF-B). The diacylphloroglucinol compound 2 and the alkylated acylphloroglucinol compound 4 inhibited iNOS with IC50 values of 19.0 and 19.5 M, respectively, and NF-B with IC50 values of 34.0 and 37.5 M, respectively. These compounds may serve as leads for the synthesis of more potent anti-inflammatory compounds for future drug discovery.
