Abstract

Gossypol at micromolar concentrations (2 microM) was found to inhibit axonal transport and a microsomal ATPase activity in the frog sciatic nerve, although axonal microtubules and the neuronal content of AMP, ADP and ATP were not affected. At slightly higher concentrations (30-40 microM), gossypol also inhibited microtubule assembly and neuronal energy metabolism. Gossypol accumulated in the nerve and the results indicate that gossypol may act as a potent neurotoxin.

摘要

已发现微摩尔浓度(2微摩尔)的棉酚可抑制青蛙坐骨神经中的轴突运输和微粒体ATP酶活性,尽管轴突微管以及AMP、ADP和ATP的神经元含量未受影响。在略高浓度(30 - 40微摩尔)时,棉酚还会抑制微管组装和神经元能量代谢。棉酚在神经中蓄积,结果表明棉酚可能是一种强效神经毒素。
