Design, synthesis, characterization, invitro anticancer evaluation, computational studies, and in silico ADME assessment of New N-(5-o-tolyl-1,3,4-oxadiazol-2-yl) alkanamides

The present article focuses on the synthesis, docking, and anticancer efficacy of a new class of N-(5-o-tolyl-1,3,4-oxadiazol-2-yl) alkanamides (3a–j). ¹HNMR, ¹³CNMR, Mass and Infrared spectral data established structures of all the analogues. We employed the MTT assay to estimate the potential anticancer efficacy of all the prepared analogues on MCF-7 cell lines. Among the derivatives tested, N-(5-o-tolyl-1,3,4-oxadiazol-2-yl)octanamide (3g) and N-(5-o-tolyl-1,3,4-oxadiazol-2-yl)dodecanamide (3j) exhibited remarkable anticancer activity; cisplatin is used as a standard reference. The active position of the EGFR protein complex with erlotinib (PDB ID: 1M17) was utilized for molecular docking analysis of the titled analogues. Among all the synthesized compounds 3j (-7.89 kcal/mol), 3g (-7.72 kcal/mol) and 3h (-7.34 kcal/mol) showed good binding affinity. An insilico ADME evaluation was conducted to estimate the drug likeness of synthesized compounds.
