Abstract
A new series of 2,4-dimethyl-1H-pyrrole-3-carboxamide derivatives bearing benzimidazole moiety was synthesized through a molecular hybridization approach and evaluated for in vitro anticancer activity by NCI-60 on leukemia, melanoma, lung, colon, CNS, ovarian, renal, prostate and breast cancer cell lines at a single dose (10µM). Among all the synthesized conjugates, some derivatives showed more or less good activity even at such a small dose, while, compound 5-(1H-benzo[d]imidazol-2-yl)-N-(1-cyclohexylethyl)-2,4-dimethyl-1H-pyrrole-3-carboxamide (8f) displayed significant antiproliferative activity specifically against MDA-MB human cancer cell lines. Compound 8f showed promising activity against MDA-MB-435 cell line of melanoma (Growth inhibition: 62.46%) and MDA-MB-468 cell line of breast (Growth inhibition: 40.24%). Computational ADME study qualified its significant physicochemical, pharmacokinetic and drug-likeness properties with good predicted oral bioavailability. Thus this new hybrid molecules would be useful for further anticancer drug development.
