Human deoxyribonucleic acid topoisomerases: molecular targets of anticancer drugs.
Mammalian cells contain two distinct types of topoisomerases. They have been mechanistically classified into a type I (topo I) and type II (topo II) enzyme. Anticancer drugs which target topo I include camptothecin, irinotecan, topotecan, and 9-aminocamptothecin. Anticancer drugs which target topo II include etoposide, mitoxantrone, teniposide, and doxorubicin. Much experimental work has indica...
متن کاملDNA topoisomerases as targets for chemotherapy.
DNA topoisomerases are ubiquitous enzymes that alter the configuration or topology of DNA. These enzymes play an important role in replicational, recombinational, and transcriptional events and are a key to cell growth processes. A number of therapeutically useful drugs apparently exert their effects by interfering with DNA topoisomerization reactions. Several inhibitors of bacterial DNA topois...
متن کاملDNA Intercalators and Using Them as Anticancer Drugs
Many anticancer drugs in clinical use interact with DNA through intercalation, which is process that starts with the transfer of the intercalating molecule from an aqueous environment to the hydrophobic space between two adjacent DNA base pairs. In general, intercalatig agents are two types: monofunctional and bifunctional. Monofunctional intercalators contain one intercalating unit and Bifunct...
متن کاملInhibitors of topoisomerases as anticancer drugs: problems and prospects.
DNA topoisomerases, which solve topological problems associated with various DNA transactions, are the targets of many therapeutic agents. Various topoisomerase inhibitors especially, topo-poisons, camptothecin (topo-I) and etoposide (topo-II) are some of the drugs that are used in the current treatment protocols, particularly for the treatment of leukemia (AML, ALL etc). However, tumor resista...
