Potent Antitumour Activity of (-)Epigallocatechin Gallate: Indications from In Vitro, In Vivo and in Silico Studies
Antitumour efficacy of (-)epigallocatechin-3-gallate (EGCG) was evaluated in vitro against the cancer cell lines BxPC-3 (pancreatic cancer), A549 (lung cancer), SH-SY5Y (neuroblastoma), MDA-MB-231 and MCF-7 (breast cancer); in vivo in nude mice by tumour growth inhibition of pancreatic cancers (BxPC-3, MIAPaCa-2), breast cancer (MDA-MB-231), and in silico by docking studies. EGCG significantly inhibited these cancer cell lines in vitro and showed significant tumour reduction in vivo. EGCG docked on to the Her-2 receptor (1N8Y) and the tubulin dimer receptor at a site other than the existing docetaxel ligand. Overall our results suggest that EGCG has potent antineoplastic activity.
