COMPARATIVE STUDY OF IN SILICO AND IN VITRO ANTICANCER ACTIVITY OF TRADITIONAL INDIAN MEDICINAL PLANTS-A REVERSE PHARMACOLOGICAL APPROACH

Abstract

Objective: Cancer is one of the major deaths occurring worldwide and its prophylaxis demands the daily consumption of extracts or dietary supplements of traditional medicinal plants which possess anticancer activities. This study focuses on the evaluation of the chemo preventive and antiproliferative effects of the active constituents of Indian medicinal plants such as Withaniasomnifera, Phyllanthusemblica and Zingiberofficinale by in silico and in vitro studies.Methods: In silico docking analysis is performed using Molegro Virtual Docker choosing the targets as p-glycoprotein and thymidylate synthase for the identified phytoconstituents. In vitro colorimetric cell metabolic activity assay is performed for the standardized extracts of these plants in various cell lines using the standards.Results: The phytoconstituents in the plants, Withaniasomnifera and Phyllanthusemblica revealed good binding affinity towards thymidylate synthase and p-glycoprotein respectively as compared to that of the standards.Conclusion: Phyllanthusemblica showed a maximal antiproliferative effect on breast cancer cell lines (MCF-7) when compared to the other plant extracts. Zingiber officinalis was found to inhibit HT-29 cell lines to a greater extent and Withaniasomniferum resulted in highest A549 cell death. A combination of these extracts in any dosage form could be used in the therapeutic efficacy in cancer.
