One pot synthesis and anticancer activity of dimeric phloroglucinols

A series of dimeric phloroglucinol compounds were synthesized in a single step using commercially available phloroglucinol and methanesulfonic acid. Based on the reported anticancer activity of plant derived dimeric phloroglucinols, these synthesized compounds were evaluated for their in vitro anti-proliferative activities against various cancer cell lines. Several compounds demonstrated in vitro cytotoxic effects across a wide array of tumor cell types. The compound 29 with pyridin-3-yl group on linker methylene and two diisovaleryl phloroglucinol moieties was found to be the most active in all the five cancer cell lines having a low IC50 of 5.5 μM in colon cancer cell lines (HCT116).

A one pot synthesis of dimeric phloroglucinol compounds was achieved from commericially available phloroglucinol. The synthesized compounds were evaluated for their in vitro anti-proliferative activities against various cancer cell lines.Figure optionsDownload as PowerPoint slide
