棉酚 用途与合成方法
棉酚（gossypol），又称棉毒素或棉籽醇，是棉属植物体内形成的一种黄色多酚二萘化合物。
Gossypol (BL 193) 是一种从棉籽和根中分离出来的口服活性的多酚。Gossypol 是一种 5α-reductase 1 和 3α-hydroxysteroid dehydrogenase 的有效抑制剂，在无细胞试验中，对应的IC50值分别为3.33 μM和0.52 μM。Gossypol 还可抑制BH3肽与Bcl蛋白的结合，对 Bcl-XL 和 Bcl-2 的IC50值分别为0.4 μM和10 μM。Gossypol 在各种癌细胞中可诱导凋亡和细胞的生长抑制。| 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 |
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).
