Abstrakt: A series of new pyrazolo-benzothiazole hybrids (7-26) were synthesised and screened for their cytotoxic activity towards several cancer cell lines [colon (HT-29), prostate (PC-3), lung (A549), glioblastoma (U87MG)] and normal human embryonic kidney cell line (Hek-293T). Compounds 8, 9, 13, 14, 18, 19, 23, and 24 displayed significant activity, with compound 14 being particularly potent towards all the tested cancer cell lines with IC 50 values in the range 3.17-6.77 μM, even better than reference drug axitinib (4.88-21.7 μM). Compound 14 also showed the strongest growth inhibition in 3D multicellular spheroids of PC-3 and U87MG cells. The mechanism of cellular toxicity in PC-3 cells was found to be cell cycle arrest and apoptosis induction through depolarisation of mitochondrial membrane potential, increased ROS production and subsequent DNA damage. Further, compound 14 displayed significant in vitro (VEGFR-2 inhibition) and in vivo [transgenic zebrafish Tg(flila:EGFP) model] antiangiogenic properties. Overall, these results provide strong evidence that compound 14 could be considered for a lead candidate in anticancer and antiangiogenic drug discovery.
