Camptothecin

(19S)-19-ethyl-19-hydroxy-17-oxa-3,13-diazapentacyclo[11.8.0.0^{2,11}.0^{4,9}.0^{15,20}]henicosa-1(21),2(11),3,5,7,9,15(20)-heptaene-14,18-dione

C20H16N2O4 (348.111)


Camptothecin is a pyranoindolizinoquinoline that is pyrano[3,4:6,7]indolizino[1,2-b]quinoline which is substituted by oxo groups at positions 3 and 14, and by an ethyl group and a hydroxy group at position 4 (the S enantiomer). It has a role as an EC 5.99.1.2 (DNA topoisomerase) inhibitor, an antineoplastic agent, a genotoxin and a plant metabolite. It is a pyranoindolizinoquinoline, a tertiary alcohol, a delta-lactone and a quinoline alkaloid. Camptothecin is an alkaloid isolated from the stem wood of the Chinese tree, Camptotheca acuminata. This compound selectively inhibits the nuclear enzyme DNA topoisomerase, type I. Several semisynthetic analogs of camptothecin have demonstrated antitumor activity. Camptothecin is a natural product found in Archidendron lucidum, Merrilliodendron megacarpum, and other organisms with data available. Camptothecin is an alkaloid isolated from the Chinese tree Camptotheca acuminata, with antineoplastic activity. During the S phase of the cell cycle, camptothecin selectively stabilizes topoisomerase I-DNA covalent complexes, 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. (NCI) An alkaloid isolated from the stem wood of the Chinese tree, Camptotheca acuminata. This compound selectively inhibits the nuclear enzyme DNA TOPOISOMERASES, TYPE I. Several semisynthetic analogs of camptothecin have demonstrated antitumor activity. A pyranoindolizinoquinoline that is pyrano[3,4:6,7]indolizino[1,2-b]quinoline which is substituted by oxo groups at positions 3 and 14, and by an ethyl group and a hydroxy group at position 4 (the S enantiomer). Camptothecin (CPT), a kind of alkaloid, is a DNA topoisomerase I (Topo I) inhibitor with an IC50 of 679 nM[1]. Camptothecin (CPT) exhibits powerful antineoplastic activity against colorectal, breast, lung and ovarian cancers, modulates hypoxia-inducible factor-1α (HIF-1α) activity by changing microRNAs (miRNA) expression patterns in human cancer cells[2][3].

Hydroxyurea

N-Carbamoylhydroxylamine

CH4N2O2 (76.0273)


Hydroxyurea is only found in individuals that have used or taken this drug. It is an antineoplastic agent that inhibits DNA synthesis through the inhibition of ribonucleoside diphosphate reductase. [PubChem]Hydroxyurea is converted to a free radical nitroxide (NO) in vivo, and transported by diffusion into cells where it quenches the tyrosyl free radical at the active site of the M2 protein subunit of ribonucleotide reductase, inactivating the enzyme. The entire replicase complex, including ribonucleotide reductase, is inactivated and DNA synthesis is selectively inhibited, producing cell death in S phase and synchronization of the fraction of cells that survive. Repair of DNA damaged by chemicals or irradiation is also inhibited by hydroxyurea, offering potential synergy between hydroxyurea and radiation or alkylating agents. Hydroxyurea also increases the level of fetal hemoglobin, leading to a reduction in the incidence of vasoocclusive crises in sickle cell anemia. Levels of fetal hemoglobin increase in response to activation of soluble guanylyl cyclase (sGC) by hydroxyurea-derived NO.

Telomestatin is a naturally occurring organic compound classified as a cyclic phenolphthioceramide derivative. It is isolated from the fermentation broth of microorganisms and is known for its antitumor properties. The name "telomestatin" reflects its primary mode of action, which is the inhibition of telomerase, an enzyme crucial for the maintenance of chromosome stability and cell proliferation, particularly in cancer cells where telomerase activity is often elevated. Telomerase is responsible for adding repetitive DNA sequences called telomeres to the ends of chromosomes, which prevents the loss of genetic material during DNA replication and cell division. By inhibiting telomerase, telomestatin interferes with the ability of cancer cells to divide and proliferate, making it a potential candidate for antitumor therapy. The compound's unique chemical structure allows it to bind specifically to the telomerase RNA component, thereby blocking the enzyme's activity. The discovery and study of telomestatin have contributed to the understanding of telomerase biology and the development of potential therapeutic strategies for cancer treatment.
