Abstract
AbstractHemithioindigos were designed as topoisomerase inhibitors, synthesized, and evaluated for their anticancer properties against lung (A549) and breast (MDA‐MB‐468 and MCF7) cancer cell lines. Among all the synthetics, three compounds exerted potential anticancer effects on A549 (lung) and MCF7 (breast) cancer cell lines at low micromolar concentrations. The results revealed that two of these compounds blocked the cancer cells at the G1/S phase, while the third compound showed moderate G2/M inhibition, leading to necrotic cell death. Finally, the topoisomerase inhibition assays revealed their potent Topo I/II inhibitory actions as one of the primary anticancer mechanisms. Molecular docking studies further corroborated these findings.
