Novel water-soluble paclitaxel prodrugs were designed and synthesized by introducing morpholino groups through different linkers. These derivatives showed 400-20,000-times greater water solubility than paclitaxel as well as comparable activity in MCF-7 and HeLa cell lines. The prodrug PM4 was tested in the S-180 tumor mouse model, with paclitaxel as the positive control. The results showed that PM4 had comparable antitumor activity as paclitaxel, with tumor inhibition of 54% versus 56%, and remarkably decreased toxicity. The survival rate of treated mice was 8/8 in the PM4 group, compared to 3/8 in the paclitaxel group.
通过不同的连接基引入吗啉代基团,设计并合成了新型水溶性紫杉醇前药。这些衍生物的水溶性比紫杉醇高400 - 20000倍,并且在MCF - 7和HeLa细胞系中具有相当的活性。以紫杉醇作为阳性对照,在前药PM4在S - 180肿瘤小鼠模型中进行了测试。结果表明,PM4具有与紫杉醇相当的抗肿瘤活性,肿瘤抑制率分别为54%和56%,且毒性显著降低。PM4组治疗小鼠的存活率为8/8,而紫杉醇组为3/8。
