Abstract
The development and discovery of steroidal drugs to cure cervical cancer is of the most important. The Claisen condensation of androstene and estrone with aromatic aldehydes was catalyzed by potassium tert. butoxide in tert. butanol to give the corresponding 2-arylidene and 16-arylidene estrone. Subsequently, the 16-arylidene estrone reacted with acid chloride in presence of quaternary amine in halogenated solvent resulting in the steroidal arylidene derivatives. Synthesis, Characterization and in vitro cytotoxic activity of arylidenes are rationalized. Fifteen compounds are synthesized and six of them were evaluated for cytotoxic activity against cervical cancer cell line. HT-3 cell line examination revealed a considerable growth inhibition. Compounds 4a, 4b, 6b, 8c, and 8d, which are estrone-based arylidenes, are the most potent of the series, with IC50 value of 7.15, 10.76, 6.37, 3.56, and 1.55 µM/ml against HT-3 cell line. In addition, molecular docking studies were performed for the steroidal arylidenes to elucidate the binding interactions. Compound 4a, 4b, 6b, 8c and 8d showed excellent binding energy. Docking studies agreed well with in vitro studies. The end result offers an alternative approach to develop steroidal arylidenes that are more effective and are based on estrone, leading to the development of novel anticancer agents.
