    Design, Synthesis, and Anticancer Evaluation of Hemithioindigos via Inhibition of Human Topoisomerases
    (John Wiley and Sons Inc, 2023-11-06T00:00:00) Kaur, Manpreet; Suman, Prabhat; Arora, Sahil; Singh, Tashvinder; Munshi, Anjana; Singh, Sandeep; Kumar, Raj
    Hemithioindigos 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. � 2023 Wiley-VCH GmbH.

    Design, Synthesis and Biological Evaluation of New 5-(2-Nitrophenyl)-1-aryl-1H-pyrazoles as Topoisomerase Inhibitors
    (John Wiley and Sons Inc, 2021-07-09T00:00:00) Kaur, Manpreet; Mehta, Vikrant; Arora, Sahil; Munshi, Anjana; Singh, Sandeep; Kumar, Raj
    5-(2-Nitrophenyl)-1-aryl-1H-pyrazoles are designed as topoisomerase (Topo) inhibitors, synthesised and assessed for their anticancer properties against breast (MDA-MB-231 and MCF7), lung (A549), and colorectal (HCT116) cancer cell lines. All the compounds induced significant cytotoxicity at low micromolar concentration. The compound 5e exerted potential anticancer effects on breast cancer cell lines at a low micromolar level (IC50<2 ?M), and showed negligible toxicity towards normal cells. Compound 5 e reduced reactive oxygen species (ROS) level in breast cancer cells, altered mitochondrial membrane potential and induced the cell cycle arrest at the G2/M phase. This was accompanied by downregulation of oncogenic p-Akt and upregulation of p-PTEN along with modulation of apoptotic markers suggesting multiple mechanisms to reduce cancer cell viability. Finally, the topoisomerase inhibition assay revealed the inhibitory activity of 5 e against Topo I and Topo II. � 2021 Wiley-VCH GmbH.
