Definitions of Gossypol

- An anticancer drug extracted from the cotton plant

- Gossypol is a polyphenol C30H30O8derived from the cottonseed plant (genus Gossypium, family Malvaceae)used as a male oral contraceptive in China. Its efficacy is comparable to the female birth control pill.

- A pigment normally found in cotton which gives this crop some resistance to insects
Gossypol Biological Properties

  • A polyphenolic aldehyde that permeates cells and acts as an inhibitor for several dehydrogenase enzymes.
  • Gossypol is antimalarial being the selective inhibitor of Plasmodium falciparum (pfLDH over hLDHs), an essential enzyme for energy generation within malarial parasite.
  • Posesses proapoptotic properties, probably due to the regulation of the Bax and Bcl2.
  • Reversibly inhibits Calcineurin and binds to calmodulin.
  • Inhibits replication of the HIV-1 virus.
  • An effective protein kinase C inhibitor.

Gossipol, Gossypol Dipotassium Salt; Gossypol Sodium Salt; Gossypol, (+)-Isomer; Gossypol, (+-)-Isomer; Gossypol, (-)-Isomer; Dipotassium Salt, Gossypol; Sodium Salt, Gossypol.

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.


A plant genus of the family MALVACEAE. It is the source of COTTON FIBER; COTTONSEED OIL, which is used for cooking, and GOSSYPOL. The economically important cotton crop is a major user of agricultural PESTICIDES.
