发布时间:2021-10-27 07:45
目的合成乳糖-多柔比星两亲性小分子并制备成纳米胶束,并对其肝癌靶向性和体内抗肿瘤药效及安全性进行评价。方法采用薄膜水化法制备乳糖-多柔比星纳米胶束(lactose-doxorubicin nanomicelles,Lac-DOX NMs),采用动态光散射法测定其粒径,透射电镜观察形态;通过细胞摄取实验考察Lac-DOX NMs对肿瘤细胞的靶向性; CCK-8法测定纳米胶束和游离多柔比星的细胞毒性;构建BALB/c-nu小鼠皮下移植瘤模型,考察Lac-DOX NMs的体内抗肿瘤药效;通过血生化检测,考察该制剂对小鼠肝功能的影响以评价制剂的安全性。结果成功制备了乳糖-多柔比星纳米胶束(Lac-DOX NMs),粒径为(169. 2±0. 9) nm;细胞摄取实验表明,Lac-DOX NMs对Hu H-7肝癌细胞具有靶向性;细胞毒性实验测得纳米胶束和游离DOX的IC50分别为3. 596和2. 131μg·mL-1;药效实验结果显示,Lac-DOX NMs能够显著抑制小鼠移植瘤的增长,Lac-DOX NMs高、低剂量的肿瘤抑制率分别为69. 72%和52. 40%,均高...

乳糖-多柔比星(Lac-DOX)的合成路线
Lac-DOX是具有两亲性的小分子,通过薄膜水化的方法,可在水溶液中自组装成具有一定粒径的胶束。制备的Lac-DOX纳米胶束表征见图3,图3A表明胶束的粒径大小为(169.2±0.9)nm,多分散系数为(0.222±0.010),Zeta电位为+2.00 m V。制备的Lac-DOX纳米胶束外观红色透明,由透射电镜(图3B)可观察到纳米胶束外观圆整,多为球形粒子,粒径分布比较均匀,粒径大小约为150 nm左右,与粒径仪测得结果相符。3.3 Lac-DOX NMs在细胞水平的评价研究
构建了裸鼠皮下MHCC-97H肿瘤模型,小鼠体内抗肿瘤实验结果见图5,与生理盐水组(saline)相比,DOX组、Lac-DOX低剂量组(Lac-DOX L)以及Lac-DOX高剂量组(Lac-DOX H)都对小鼠肿瘤有明显的抑制作用,其中生理盐水组与Lac-DOX L组肿瘤体积增长有显著差异(P=0.006 1),DOX组与Lac-DOX H组肿瘤体积增长有显著性差异(P=0.009 3)。此外DOX组与Lac-DOX L组对肿瘤的抑制率分别为52.27%和52.40%。而Lac-DOX H组抑制率为69.72%,约为DOX组的1.33倍(P=0.000 16),其对肿瘤抑制作用增强。给药组对肿瘤的抑制效果见图5C。给药后,给药组与生理盐水组相比,小鼠体重无明显差异。图4 Lac-DOX纳米胶束的细胞摄取图(A,×600)和细胞生存曲线图(B).n=3,
