说明

一般描述

Chemical structure: taxoide
 

应用

Paclitaxel has been used to study PREP2-tubulin interactions using coimmunoprecipitation assays on NIH3T3 cell extracts. This drug has also been used to stabilize tubulin obtained from pig brain.
 

生化/生理作用

紫杉醇是一种有效的抗肿瘤和抗有丝分裂的紫杉烷类药物，可与β-微管蛋白的N端结合，并使微管稳定，使细胞周期停滞在G2/M期。微管损伤可通过JNK依赖性途径和JNK非依赖性途径诱导凋亡，这可能与蛋白激酶A（PKA）或Raf-1激酶的激活有关，导致Bcl-2磷酸化。经由CYP2CB的主要代谢物为6α-羟基紫杉醇(6α-OHP)。

注意

紫杉醇可在甲醇中进行酯交换反应，并在水溶液中发生水解。
 

制备说明

Paclitaxel is soluble in DMSO at 50 mg/ml and can be stored frozen for several months. It is also soluble in methanol (undergoes transesterification), acetonitrile and ethanol. Paclitaxel is rapidly destroyed in weakly alkaline, methanolic solutions and in strongly acidic methanolic solutions (1:1 of methanol:concentrated HCl). It is also soluble in a mixture of 50% Cremophor EL and 50% anhydrous ethanol.
