Description
技术领域
本发明属于生物医药技术领域,具体涉及一种用于肿瘤药物深入递送的温敏型纳米药物制剂及其制备方法与应用。
背景技术
化疗作为临床上癌症患者的首选治疗手段,但是它面临诸如小分子化疗药物的溶解性差、靶向性差,导致全身毒副作用大,副反应严重,肿瘤部位药物富集量低,治愈效果差等严峻挑战。据报道,纳米载体能够有效提高化疗药物的靶向性、稳定性和负载率,所以利用纳米载体协助化疗,不仅增加化疗药物的溶解性,而且增强肿瘤的EPR效应,从而提高载药纳米粒子在肿瘤部位的富集量。50~100nm的纳米粒子具有较强的EPR效应,但是该尺寸的纳米载体在经过血液循环富集到肿瘤血管附近后,由于实体瘤外部一层紧密排列的基质细胞与内部较高的流体渗透压,使得纳米药物载体很难进一步深入渗透到实体瘤内部。
发明内容

有益效果
1).本发明提供的肿瘤药物深入递送的温敏型纳米药物制剂在近红外光的照射下(例如波长为650~900nm的激光照射下),产生温和光热,使药物制剂中温敏型中间体Azo-linker断裂并产生非氧依赖性自由基,具有光热治疗(PTT)和光动力治疗(PDT)的效果。此外,温和光热能引起所述药物制剂在肿瘤血管部位的富集,提高所述药物制剂的靶向性,从而增加化疗药物在肿瘤部位的富集量。
2).本发明提供的肿瘤药物深入递送的温敏型纳米药物制剂在在光热响应后,释放出尺寸5nm以下连接化疗药物的树枝状分子。由于其尺寸较小,可以穿过基质细胞的间隙,同时克服肿瘤内部较高的流体渗透压,此外,树枝状分子表面氨基化带正电,因而更容易有效地被肿瘤细胞吞噬,使药物制剂高效地抑制肿瘤的增殖、转移和复发。从而实现对肿瘤的高效富集、定点释放、深入递送,协同治疗,达到安全高效的肿瘤治疗效果。
3).本发明的药物制剂所采用的原料相对容易得到,且具有可降解,毒副作用小等优点。并且,对于不同肿瘤,可在树枝状分子上连接不同的化疗药物,因而药物制剂的药效更优。
4).本发明的制备方法相对简单,可实现大规模生产。

3).称取步骤1)和2)中得到的PCL4000-Azo-COOH 15.6mg和PAMAM/FITC12mg、活化剂EDC 25mg和NHS 25mg分别溶解在DMSO中,然后混合在室温下反应1h,得到连有6-FITC的温敏型聚合物链PCL4000-Azo-PAMAM/FITC,之后利用截流分子量为1000000Da的透析袋透析,冻干,得到橙色固体;
4)称取RHB 5.0mg,疏水性聚合物链PCL400012mg,缩合剂DIC 1.3mg和DMAP 1.3mg分别溶解在DMSO中,然后混合在室温下反应48h,得到PCL4000-RHB,之后利用截留分子量为10000Da的透析袋透析,冻干,得到粉色固体;
5)将连有6-FITC的温敏型聚合物PCL4000-Azo-PAMAM/FITC、亲疏水性嵌段聚合物链PCL5000-b-PEG5000、连有RHB的疏水性聚合物链PCL4000-RHB和光热转换材料IR780以质量比为1:1:1:0.1分别溶解在二甲亚砜中,然后混合搅拌均匀后,边搅拌边加入水,得到两种染料标记的深入递送的温敏型纳米药物制剂,之后利用截留分子量为1000000Da的透析袋透析即可。
将浓度为200μg/mL两种染料标记的深入递送的温敏型纳米药物制剂加入到4T13D细胞球中,采用不照激光和用808nm激光进行照激光(3min)的方式对照处理,再共培养2h,之后吸出3D细胞球并用PBS溶液清洗两遍将未被吞噬的纳米粒子除去,用激光共聚焦显微镜成像。两种染料标记的深入递送实验结果如图9所示,光热响应后连有6-FITC的树枝状分子可以深入递送到3D细胞球内部,为图中颜色较浅部分,而RHB由于其标记在纳米粒子上,仍在3D细胞球外部,为图中颜色较深部分,表明本发明的药物制剂确实可以通过光热响应以实现深入递送的效果。
基于该效果实验可知,采用不同药物分子制备成本发明的温敏型纳米药物制剂也能实现通过光热响应从而深入递送的效果。
以上,对本发明的实施方式进行了说明。但是,本发明不限定于上述实施方式。凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
