Development of New N- and S-substituted-imidazolidin-4-one Analogues with Potent Anti-breast Cancer Activity: In vitro Molecular Docking Assessment

2-Thioxoimidazolidin-4-one derivatives 3, 4, 7, 8, and 9 have been synthesized from 3- (benzylideneamino)-2-thioxoimidazolidin-4-one (2) as a starting material. Compounds 3, 4, 7, 8, and 9 were obtained via the reaction of compound (2) with ethyl chloroacetate, methyl acrylate, and chlorophenacyl bromide, respectively. Elemental analysis and several spectroscopy techniques were used to confirm the synthesized compounds. The synthesized compounds, particularly compounds 7 and 8, exhibited significant cytotoxic influences on MCF-7 cells, surpassing staurosporine. Compounds 7 and 8 can induce apoptosis in those treated MCF-7 cells. Studying molecular docking approved that compounds 7 and 8 bind in two and three dimensions to the aromatase binding pockets. Molecular modeling indicates compounds 7 and 8 have a strong affinity for human topoisomerase II beta, establishing its promise as a multifaceted antitumor agent for breast cancer.
