Design, Synthesis, Evaluation and Molecular Docking Studies of Novel Triazole Linked 1,4-Dihydropyridine-isatin Scaffolds as Potent Anticancer Agents

A series of novel triazole linked isatin-dihydropyridine hybrids (N1-N15) have been synthesized and examined for their anti proliferative activity against human cancer cell lines viz. HeLa, Huh-7, PC-3, IMR-32 and MCF-7. All of the synthesized hybrids have shown moderate to potent cytotoxicity against all the tested cell lines except IMR-32. Compounds N1, N2 and N13 have displayed an enhanced inhibitory potency against Huh-7 cell line as compared to the standard drug, doxorubicin. Out of the three, N2 has shown the highest in vitro inhibitory action with IC50 values of 6.73 +/- 0.33 mu M and 17.94 +/- 0.23 mu M against Huh-7 and MCF-7 cell lines, respectively. The docking studies of these most potent compounds have also been investigated which identified that N2 might be an excellent drug-like candidate worthy of further pursuit.

Automated summary

A series of novel triazole linked isatin-dihydropyridine hybrids have been synthesized and tested for their anti proliferative activity against human cancer cell lines. Compound N2 showed the highest inhibitory action and may be an excellent drug-like candidate for further pursuit.
