| In vitro study | Gossypol, a natural product isolated from cottonseeds and roots that has been studied as an anticancer agent. The racemic form of Gossypol [(±)-Gossypol] is tested in several clinical trials and is well tolerated. The racemic form Gossypol ((±)-Gossypol) binds to Bcl-xL protein with a K i of 0.5 to 0.6 μM. (±)-Gossypol also potently binds to Bcl-2 protein with a K i value of 0.2-0.3 mM. The natural racemic Gossypol has two enantiomers, namely the (-)-Gossypol and (+)-Gossypol enantiomers. The racemic form and each of the enantiomers of Gossypol are tested against UM-SCC-6 and UM-SCC-14A in 6-day MTT assays. (-)-Gossypol exhibits greater growth inhibition relative to (±)-Gossypol than (+)-Gossypol in both cell lines tested (P<0.001). An intermediate growth inhibitory effect is observed with (±)-Gossypol but this effect is only observed at the higher dose of Gossypol (10 μM, P<0.0001). |

NSC 56817 - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| introduction | gossypol (gossypol), also known as cotton toxin or cottonseed alcohol, is a yellow polyphenol dinaphthalene compound formed in cotton plants. |
| biological activity | Gossypol (BL 193) is an orally active polyphenol isolated from cottonseed and root. Gossypol is an effective inhibitor of 5α-reductase 1 and 3α-hydroxysteroid dehydrogenase. In the cell-free test, the corresponding IC50 values are 3.33 μM and 0.52 μM respectively. Gossypol can also inhibit the binding of BH3 peptide to Bcl protein, and the IC50 values for Bcl-XL and Bcl-2 are 0.4 μM and 10 μM respectively. Gossypol can induce apoptosis and cell growth inhibition in various cancer cells. |
| Target | Value |
| Bcl-xL (Cell-free assay) | 0.4 μM |
| 3α-hydroxysteroid dehydrogenase (Cell-free assay) | 0.52 μM |
| 5α-reductase 1 (Cell-free assay) | 3.33 μM |
| Bcl-2 (Cell-free assay) | 10 μM |
| use | gossypol has anti-tumor effect and can be used as a male contraceptive. |
