Topotecan is only found in individuals that have used or taken this drug. It is an antineoplastic agent used to treat ovarian cancer. It works by inhibiting DNA topoisomerases, type I. [PubChem]Topotecan has the same mechanism of action as irinotecan and is believed to exert its cytotoxic effects during the S-phase of DNA synthesis. Topoisomerase I relieves torsional strain in DNA by inducing reversible single strand breaks. Topotecan binds to the topoisomerase I-DNA complex and prevents religation of these single strand breaks. This ternary complex interferes with the moving replication fork, which leads to the induction of replication arrest and lethal double-stranded breaks in DNA. As mammalian cells cannot efficiently repair these double strand breaks, the formation of this ternary complex eventually leads to apoptosis (programmed cell death).Topotecan mimics a DNA base pair and binds at the site of DNA cleavage by intercalating between the upstream (âˆ’1) and downstream (+1) base pairs. Intercalation displaces the downstream DNA, thus preventing religation of the cleaved strand. By specifically binding to the enzymeâ€“substrate complex, Topotecan acts as an uncompetitive inhibitor. Topotecan is a pyranoindolizinoquinoline used as an antineoplastic agent. It is a derivative of camptothecin and works by binding to the topoisomerase I-DNA complex and preventing religation of these 328 single strand breaks. It has a role as an EC 5.99.1.2 (DNA topoisomerase) inhibitor and an antineoplastic agent. An antineoplastic agent used to treat ovarian cancer. It works by inhibiting DNA topoisomerases, type I. Topotecan is a Topoisomerase Inhibitor. The mechanism of action of topotecan is as a Topoisomerase Inhibitor. Topotecan is a semisynthetic derivative of camptothecin, a cytotoxic, quinoline-based alkaloid extracted from the Asian tree Camptotheca acuminata. Topotecan inhibits topoisomerase I activity by stabilizing the topoisomerase I-DNA covalent complexes during S phase of cell cycle, thereby inhibiting religation of topoisomerase I-mediated single-strand DNA breaks and producing potentially lethal double-strand DNA breaks when encountered by the DNA replication machinery. An antineoplastic agent used to treat ovarian cancer. It works by inhibiting DNA TOPOISOMERASES, TYPE I. See also: Topotecan Hydrochloride (active moiety of).
