Abstract

4β-Hydroxywithanolide E, which can be obtained in large amounts from the Physalis genus, possessed anti-proliferative effects on a variety of human cancer cell lines. For discussing its anti-tumor structure-activity relationship, a series of 4β-hydroxywithanolide E derivatives (1-17) were synthesized and evaluated for their antitumor activity in vitro towards acute promyelocytic leukemia NB4 cell line by the Alarma blue assay. Cytotoxicity data revealed that the enone structure and C-4 hydroxyl substituents of ring A, together with the side chain (C-20-C-28) play an important effect on the cytotoxicity.

Keywords: 4β-Hydroxywithanolide E; Cytotoxic activity; Structure modification.
