Developing new anticancer agents are crucial for cancer treatment. Antiproliferative activity of L1H as a bisstructured Schiff base was subjected to preliminary research in eight different kinds of cell lines by the cell viability method using different concentrations to determine their inhibitory concentration. L1H demonstrated the highest cytotoxicity in human breast cancer cell line MCF7. In this perspective, the MCF7 cell line was cultured for the examination of different molecular techniques, including MTT, apoptosis analysis by enzymelinked immunosorbent assay (ELISA), and comet assay. Moreover, the DNA ladder, acridine orange/ethidium bromide as another apoptotic cell analysis, markers of oxidative stress, and total antioxidant status, total thiol, and GSH as nonenzymatic antioxidants assay were conducted. The above techniques have proven that L1H is a growth inhibitor effect when compared to cisplatin as a positive control in human breast cancer cells, especially those affected by L1H. The findings clearly show that L1H evaluated in MCF7 cell lines causes rising or induced apoptosis, DNA damage, diminished antioxidant status against the increase of oxidized protein, and prevents cell proliferation. Manifold evidence supported our hypothesis that L1H has a potential therapeutically improved effect against the MCF7 cell line, and then without a doubt is a suitable candidate drug for investigating cancers next.
