(-)-Gossypol

C30H30O8 (518.194058)

Gossypol has been used in trials studying the treatment of Non-small Cell Lung Cancer. (-)-Gossypol or (R)-Gossypol, is the R-isomer of [Gossypol]. Gossypol is a natural product found in Malva pseudolavatera, Hibiscus syriacus, and other organisms with data available. Gossypol is an orally-active polyphenolic aldehyde with potential antineoplastic activity. Derived primarily from unrefined cottonseed oil, gossypol induces cell cycle arrest at the G0/G1 phase, thereby inhibiting DNA replication and inducing apoptosis. This agent also inhibits cell-signaling enzymes, resulting in inhibition of cell growth, and may act as a male contraceptive. (-)-Gossypol is found in fats and oils. (-)-Gossypol is a constituent of Gossypium hirsutum (cotton).(-)-gossypol has been shown to exhibit anti-tumor, anti-cancer and anti-proliferative functions (A7832, A7833, A7834). A dimeric sesquiterpene found in cottonseed (GOSSYPIUM). The (-) isomer is active as a male contraceptive (CONTRACEPTIVE AGENTS, MALE) whereas toxic symptoms are associated with the (+) isomer. Gossypol, also known as gossypol, (+)-isomer or (-)-gossypol, is a member of the class of compounds known as sesquiterpenoids. Sesquiterpenoids are terpenes with three consecutive isoprene units. Thus, gossypol is considered to be an isoprenoid lipid molecule. Gossypol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Gossypol can be found in cottonseed, okra, soy bean, and sunflower, which makes gossypol a potential biomarker for the consumption of these food products. Gossypol is a non-carcinogenic (not listed by IARC) potentially toxic compound. Among other things, it has been tested as a male oral contraceptive in China. In addition to its putative contraceptive properties, gossypol has also long been known to possess antimalarial properties. Other researchers are investigating the anticancer properties of gossypol . Gossypol may cause apoptosis via the regulation of Bax and Bcl-2 proteins. It is also an inhibitor of calcineurin and protein kinases C, and has been shown to bind calmodulin (L1239) (T3DB).
