In-vitro cytotoxicity and in silico molecular docking of alkaloids from tiliacora acuminata

Abstract

Background: The present study aimed to identify the cytotoxicity of Tiliacora acuminata extract/fraction(s) plant via bioactivity guided approach and predict the binding affinity with Topoisomerase II. Materials and Methods: Extract and fractions were screened using brine shrimp lethality bioassay and the potent fraction was further evaluated for its in vitro cytotoxicity using five different cell lines i.e. HT-29, HepG2, MCF-7 and A-549. The binding affinity of individual phytoconstituent from the potent fraction with Topoisomerase II was further predicted using autodock4. Results: The fraction containing alkaloids showed the highest cytotoxicity against theHT-29 cell line.Molecular docking study identified coclaurine as a potent alkaloid phytoconstituent to bind with topoisomerase II. Conclusion: The study revealed the potential cytotoxic alkaloids from T. acuminata which may find use in the development of cytotoxic or chemopreventive agents.
