    Natural Products as an Alternative Therapy for Brain Tumors: From Bench To Bedside
    (Springer Singapore, 2022-09-28T00:00:00) Kumar, Sachin; Kumar, Mandeep; Bijalwan, Anjali; Sharma, Shubham; Kumar, Puneet
    Incremental elevation in the trends of a brain tumor in recent years accounts for 5% adult population, whereas the number exceeds 70% in the case of children. Evidence reveals an eventual metastasize of 20%-30% of malignant tumors to the brain�s different regions. Compression in the brain tissue and elevated intracranial pressure mediated by benign and malignant tumors contributed to severe consequences like the central nervous system (CNS) damage or even imperil the patient�s life. Despite multiple therapeutic strategies in the market, none of the drugs are fully effective and safe. Strategic advancement indicates chemotherapy as a treatment of choice for critical conditions like brain tumors, but the chemotherapy drugs toxicity is still a major therapeutic hurdle. Plants and their derived natural products are one of the most emerging targets to strike against brain tumors. Analogs of several natural products are already demonstrated as antitumor in nature, and day by day, advancements unfold various other plant and plant derivatives having such antitumor activity. This chapter aims to underline and emphasize the antitumor agents, which can target brain tumors procured from the natural origin such as natural products and their analogs. The available data on different plants and isolated compounds of natural origin used to reduce and arrest brain tumors is also discussed here. � Springer Nature Singapore Pte Ltd. 2022.

    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.
