Molecules, 2023 The antitumor drug topotecan (TPT) is a potent inhibitor of topoisomerase I, triggering DNA breaks lethal for proliferating cancer cells. The mechanism is common to camptothecins SN38 (the active metabolite of irinotecan) and belotecan (BLT).

TDP1/TOP1 ratio as a promising indicator for the response of small cell lung cancer to topotecan [PDF]
, 2014 BACKGROUND AND OBJECTIVE Small cell lung cancer (SCLC) is one of the most challenging tumors to treat due to high proliferation rate, early metastatic dissemination and rapid development of chemotherapy resistance.

Topoisomerase I poisons-induced autophagy: Cytoprotective, Cytotoxic or Non-protective
Autophagy Reports, 2023 Topoisomerase I inhibitors represent a widely used class of antineoplastic agents that promote both single-stranded and double-stranded breaks in the DNA of tumor cells, leading to tumor cell death.

MRE11 facilitates the removal of human topoisomerase II complexes from genomic DNA [PDF]
, 2012 Topoisomerase II creates a double-strand break intermediate with topoisomerase covalently coupled to the DNA via a 5'-phosphotyrosyl bond. These intermediate complexes can become cytotoxic protein-DNA adducts and DSB repair at these lesions requires ...

Identification of early gene expression changes in primary cultured neurons treated with topoisomerase I poisons. [PDF]
, 2016 Topoisomerase 1 (TOP1) poisons like camptothecin (CPT) are currently used in cancer chemotherapy but these compounds can have damaging, off-target effects on neurons leading to cognitive, sensory and motor deficits.

Discovery of Novel Triazole-Containing Pyrazole Ester Derivatives as Potential Antibacterial Agents
Molecules, 2019 To develop new antibacterial agents, a series of novel triazole-containing pyrazole ester derivatives were designed and synthesized and their biological activities were evaluated as potential topoisomerase II inhibitors.
