DNA topoisomerases are enzymes responsible for the relaxation of DNA torsional strain, as well as for the untangling of DNA duplexes after replication, and are important cancer drug targets. One class of topoisomerase inhibitors, "poisons", binds to the transient enzyme-DNA complex which occurs during the mechanism of action, and inhibits the religation of DNA. This ultimately leads to the accu...
Naturally occurring anziaic acid was very recently reported as a topoisomerase I inhibitor with antibacterial activity. Herein total synthesis of anziaic acid and structural analogues is described and the preliminary structure-activity relationship (SAR) has been developed based on topoisomerase inhibition and whole cell antibacterial activity.
Two set of 2-aryl-5,6-dihydropyrrolo[2,1-a] isoquinolines were designed and synthesized to evaluate their biological activities as topoisomerase inhibitors. Cytotoxic activity of the synthesized compounds 4a-e and 7a-d was assessed against several human cancer cell lines, including MCF-7 (breast cancer cell), HepG2 (liver hepatocellular cells), A549 (adenocarcinomic human alveolar basal epithel...
BACKGROUND Therapy-related myeloid neoplasm (t-MN) is a distinct class of acute myeloid leukemia (AML) in the World Health Organization (WHO) classification. Both AML and acute lymphoblastic leukemia (ALL) may develop after treatment for primary cancer. Topoisomerase inhibitors are commonly used to treat breast cancer patients and are well-known for their effect on leukemogenesis of therapy-rel...
