Design, Synthesis, and Biological Evaluation of Novel Benzofuran Derivatives Bearing N-Aryl Piperazine Moiety

Abstract

A series of novel hybrid compounds between benzofuran and N-aryl piperazine have been synthesized and screened in vitro for anti-inflammatory activity in lipopolysaccharide (LPS)-stimulated RAW-264.7 macrophages and for anticancer activity against three human tumor cell lines. The results demonstrated that derivative 16 not only had inhibitory effect on the generation of NO (IC50 = 5.28 μM), but also showed satisfactory and selective cytotoxic activity against human lung cancer line (A549) and gastric cancer cell (SGC7901) (IC50 = 0.12 μM and 2.75 μM, respectively), which was identified as the most potent anti-inflammatory and anti-tumor agent in this study.
