Paclitaxel

MCE 國際站：Paclitaxel

品牌：MedChemExpress (MCE)

CAS：33069-62-4

純度：0.9997

貨號：HY-B0015

中文名稱：紫杉醇

Synonyms：紫杉醇

存儲條件：4°C，避光保存 *溶劑中：-80°C，6 個月；-20°C，1 個月（避光保存）

運(yùn)輸條件：美國大陸的室溫；其他地方可能有所不同。

產(chǎn)品活性：Paclitaxel 是一種天然抗腫瘤藥，可穩(wěn)定微管蛋白 (tubulin) 的聚合。Paclitaxel 可導(dǎo)致有絲分裂停滯和誘導(dǎo)細(xì)胞凋亡 (apoptosis)，最終導(dǎo)致細(xì)胞死亡。Paclitaxel 還可誘導(dǎo)細(xì)胞自噬 (autophagy)。

體外：Paclitaxel (20 nM；48 h) 誘導(dǎo)程序性細(xì)胞死亡，并在細(xì)胞周期的 G2/M 期存在阻滯[1]。 Paclitaxel (20 nM；48 hours) 誘導(dǎo) p53 水平的持續(xù)增加[1]。 MCE尚未獨(dú)立證實(shí)這些方法的準(zhǔn)確性。僅供參考。

體內(nèi)：Paclitaxel (1 -20 mg/kg；腹腔注射；1次/2天，共5個周期) 在低 Paclitaxel 組明顯誘導(dǎo)肝轉(zhuǎn)移，對原發(fā)腫瘤生長影響不大[3]。 MCE尚未獨(dú)立證實(shí)這些方法的準(zhǔn)確性。僅供參考。
