The bioactive compounds proceraside A, frugoside and calotropin, which were extracted from the root bark of Calotropis procera (Aiton) W.T. Aiton (family Asclepiadaceae), were recently reported to inhibit the growth of inhibition against various human cancer cell lines in vitro. However, their modes of action have not been clearly defined. Therefore, we attempted an in silico approach to gain insights into their binding modes against the following selected molecular targets: CDK-2, CDK-6, topoisomerase I, BCL-2, VEGFR-2, telomere: G-quadruplex, and topoisomerase II. These targets were selected based on their key roles in cancer progression via the regulation of the cell cycle and DNA replication. Molecular-docking analyses revealed that proceraside A was the best docked ligand against all the targets, with the exception of telomere-G: quadruplex. Furthermore, it displayed the lowest binding energies and inhibition constants, and critical hydrogen bonds and hydrophobic interactions with the targets were also revealed. The present study may aid in the identification of possible targets for proceraside A, and might provide a plausible explanation for its proven anti-tumor activities. Moreover, the result of this study may further guide structure-activity relationship studies used to generate more potent target-specific inhibitors.
