目的:制备一种包封率、载药量高的紫杉醇载体材料。方法:开环聚合法一步合成了两种两亲性共聚物PTL1 和PTL2,以核
磁和凝胶渗透色谱进行了产物的表征,以固体分散- 超声法制备紫杉醇胶束,考察了胶束的载药量、包封率。结果:核磁和凝胶渗
透色谱的结果显示得到了目标产物,所制备得到的载紫杉醇胶束包封率可以达到90%以上,载药量为9.5%以上。结论:实验结果
表明我们所合成的PTL1 和PTL2 是好的紫杉醇载体材料。 |

Objective:To obtain a high loading and encapsulation efficiency micellar carrier of paclitaxel.Methods:Amphiphilic
block copolymers PTL1 and PTL2, were synthesized by ring-opening polymerization and their compositon were characterized by
1H-NMR and GPC. Paclitaxel micelles were prepared through solid-dispersion-sonication method. The drug loading and encapsulation
efficiency of the micelles were investigated.Results:PTL1 and PTL2 were successfully synthesized The drug loading contents of
micelles were higher than 9.5% and the encapsulation efficiency were high than 90%.Conclusion:PTL1 and PTL2 could be promising
paclitaxel micellar carriers. |
