川楝素(toosendanin)是从楝属植物的根茎及川楝果实(川楝子)中提取的一种三萜化合物。经研究证明其通过影响K+、Ca2+通道活性作用于神经系统、呼吸系统、神经肌肉接头及消化系统。近年来研究证明其通过诱导细胞分化及凋亡从而具有抗肿瘤作用,本文综述了川楝素的抗肿瘤作用及机制,为临床开发应用提供参考。
Toosendanin,a triterpenoid extracted from the root,stalk and fruit of Melia toosendan Sieb et Zucc.It had found that toosendanin could influence the activity of K+ channels and Ca2+ channels,then effected the nervous system,respiratory system,neuromuscular junction and digestive system.Recent researches report that toosendanin plays an important role in anti-tumor by induce cancer cells differentiation and apoptosis.The effects and mechanisms of toosendanin are demonstrated on cancer cells,in order to provide some evidences for fundamental research and further study.
