Abstract: High Resolution Image Download MS PowerPoint Slide In the current study, five novel cyanoacrylamides incorporating sulfamethoxazole ( 5–9 ) were designed and synthesized as potential candidates for anticancer therapy. The antitumor potential of the synthesized compounds was screened against HCT116, MDA-MB-231, and A549 human tumor cells. Compound 9, incorporating the 4-(piperidin-1-yl)phenyl moiety, was more effective than 5-fluorouracil against the three cell lines. The shape of colon cancer cells was examined by scanning electron microscope (SEM). Compound 9 could effectively induce HCT116 apoptosis through the remarkable upregulation of Bax and caspase-3 and the downregulation of Bcl2 and survivin. It can also inhibit HCT116 cell cycle progression at the S phase and cell migration, as it significantly downregulates cyclin A1 and upregulates CDH1, respectively. According to UV–vis and EB-displacement measurements, compound 9 could interact with CT-DNA in a mild intercalative way. DNA fragmentation propensities of compound 9 were examined on pBR322 plasmid DNA using gel electrophoresis, revealing that compound 9 exhibited remarkable photofragmentation activity. Moreover, the molecular docking supported that compound 9 had good binding affinities toward the active sites of key proteins implicated in carcinogenesis and metastasis. In conclusion, compound 9 is presented as a remarkable molecule for the development of novel anticancer drugs.
