Gossypol acetic acid

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 529008

CAS#: 12542-36-8 (acetic acid)

Description: 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.
