Design, synthesis, and cytostatic activity of novel cyclic curcumin analogues

A series of novel cyclic analogues of curcumin were synthesized and analyzed for in vitro cytostatic activity. Condensation of 2-acetylcycloalkanones with a variety of aromatic aldehydes resulted in the formation of 2-arylidene-6-(3-arylacryoyl)-cycloalkanone derivatives. A number of these analogues were found to have significant anticancer activity against representative murine and human cancer cell lines during in vitro bioassays. This corroborated with in vitro cytostatic activity against a panel of 60 cell lines studied at the National Cancer Institute (USA).

Graphical abstractA number of curcumin analogues were prepared and evaluated for their cytostatic activity. Some of these analogues were found to have significant activity against three representative cancer cell lines.Figure optionsDownload full-size imageDownload as PowerPoint slide
