Abstract

A series of 1,2,3-triazole coronopilin congeners have been designed and synthesized by employing click chemistry approach starting from parthenin and evaluated for their cytotoxicity against a panel of six human Cancer cell lines (PC-3, THP-1, HCT-15, HeLa, A-549 and MCF-7). While many compounds exhibited significant Anticancer activity, compound 3a, was found to be the most promising analogue in this series with IC50 values of 3.1 μM on PC-3 cell line. Flow-cytometric studies showed that 1,2,3-triazole derivative-3a induce dose dependent Apoptosis in the sub G1 phase. This lead molecule-3a was further studied for NF-κB (p65) transcription factor inhibitory activity using Elisa and western blotting analysis which confirmed concentration dependent inhibitory activity against NF-κB, p65 with 80% inhibition in 24 h at 100 μM.
