Abstract A new series of cyanoacrylamide was synthesized and characterized by different physicochemical and multispectral investigations. The cytotoxic potential of these compounds was assessed against different human cancer cell lines (HCT116, MCF-7, and Hep2). 4-(piperidin-1-yl)phenyl derivative 5g was selected as it showed the most promising cytotoxic activity against the HCT116 and MCF7 cell lines with IC50 values ranging from 32 to 50 µM. . Moreover, compound 5g cytotoxicity against normal human cells (WI-38) was evaluated, and the results revealed that this compound has low toxicity. Investigation of the apoptotic activity of the most active compound revealed that compound 5g could induce both the early and the late apoptosis of HCT116. Further mechanistic study of the HCT116 cell cycle confirmed the spectacular cytotoxic and apoptotic effects of compound 5g. Compound 5g showed a pronounced increase in cells in the G2/M and S phases with a concomitant reduction of cells in the G0-G1 phase. This compound also induced a significant increase in the caspase-3 activities, remarkable downregulation of the Bcl-2 (at mRNA and protein level), CDK1 and CDK2 (at mRNA level), and significant upregulation of the Bax at mRNA and protein level using qRT-PCR and ELISA. Furthermore, 5g also proved to have a good DNA binding affinity using UV-Vis measurements. Prediction of ADMET properties and oral toxicity of the drug-likeness features of compound 5g were carried out using online software. Moreover, a molecular docking study for compound 5g was performed to predict their binding affinities toward DNA and the active site of different protein sets (Bcl2, Bcl-xl, Mcl-1, XIAP, survivin, CDK1, and CDK2). Results of molecular docking were strongly correlated with that of the cytotoxicity study. |
