To develop stable paclitaxel (PTX)-loaded bovine serum albumin (BSA) nanoparticles (BSA-NPs-PTX) as drug-delivery vehicles for delivering paclitaxel into the brain to treat glioma. This study used PTX-loaded BSA NPs coated with polysorbate 80 (Ps 80) to enhance PTX concentration in the brain. The low IC indicated that the fabricated BSA-NPs-PTX and BSA-NPs-PTX-Ps 80 showed significantly enhanced cytotoxicity. The pharmacokinetic and biodistribution analysis of BSA-NPs-PTX and BSA-NPs-PTX 80 showed comparable pharmacokinetic profiles but were significantly different compared with free PTX. BSA-NPs-PTX-Ps 80 exhibited higher plasma concentration-time curves, as compared with BSA-NPs-PTX and PTX. BSA-NPs-PTX and BSA-NPs-PTX-Ps 80 showed significantly improved PTX distribution in the frontal cortex, posterior brain and cerebellum.
为了开发稳定的紫杉醇（PTX）负载牛血清白蛋白（BSA）纳米颗粒（BSA-NPs-PTX）作为药物递送载体，将紫杉醇递送至大脑以治疗神经胶质瘤。本研究使用聚山梨酯 80（Ps 80）包被的载紫杉醇 BSA NPs 来提高脑内紫杉醇浓度。低 IC 表明，所制备的 BSA-NPs-PTX 和 BSA-NPs-PTX-Ps 80 显示出显著增强的细胞毒性。BSA-NPs-PTX 和 BSA-NPs-PTX-Ps 80 的药代动力学和生物分布分析显示出可比的药代动力学特征，但与游离 PTX 有显著差异。与 BSA-NPs-PTX 和 PTX 相比，BSA-NPs-PTX-Ps 80 表现出更高的血浆浓度-时间曲线。BSA-NPs-PTX 和 BSA-NPs-PTX-Ps 80 显著提高了 PTX 在额叶皮质、后脑和小脑的分布。
