compound introduction
Larotaxel (XRP9881) 是一种紫杉烷类似物，具有抗紫杉烷抗性乳腺癌的临床前活性。Larotaxel (XRP9881) 通过促进微管蛋白装配和稳定微管发挥其细胞毒性作用，并最终通过细胞凋亡导致细胞死亡。Larotaxel (XRP9881) 具有穿越血脑屏障的能力，对 P-糖蛋白 1 的亲和力比 Docetaxel 低得多。 Larotaxel (XRP9881) is a taxane analogue with preclinical activity against taxane-resistant breast cancer. Larotaxel (XRP9881) exerts its cytotoxic effect by promoting tubulin assembly and stabilizing microtubules, ultimately leading to cell death by apoptosis. It presents the ability to cross the blood brain barrier and has a much lower affinity for P-glycoprotein 1 than Docetaxel.
