Curcuminoid (Cur) loaded polysaccharide nanoformulations with blood-brain barrier (BBB) penetration and brain targeting properties, based on hyaluronic acid (HA) and chitosan hydrochloride (CSH) (Lf-Cur-PSNPs) were developed as a novel delivery system for malignant glioma. Formulations were investigated for physicochemical characteristics, cytotoxicity, uptake, and BBB penetration. The results showed that Lf-Cur-PSNPs (concentration of Lf was 0.5mg/mL) were preferentially taken up by brain capillary endothelial cells than Cur-PSNPs at any time. After crossing the BBB, Lf-Cur-PSNPs remained largely intact and were more effective in targeting glioma cells (C6). In vivo imaging studies in mice exposed Lf-PSNPs could effectively permeate BBB and preferentially accumulate in the brain (2.39 times greater than PSNPs). Moreover, PSNPs were detected in brain up to 72h. This data indicates that Lf-Cur-PSNPs could effectively target and accumulate within the gliomas after enhanced permeation through BBB, thus should be further explored for their potential in CNS maliganancies.
基于透明质酸(HA)和盐酸壳聚糖(CSH)的姜黄素(Cur)载多糖纳米制剂具有血脑屏障(BBB)穿透和脑靶向特性,被开发为恶性神经胶质瘤的新型给药系统。研究了制剂的理化特性、细胞毒性、摄取和 BBB 穿透。结果表明,Lf-Cur-PSNPs(Lf 浓度为 0.5mg/mL)在任何时间都比 Cur-PSNPs 优先被脑毛细血管内皮细胞摄取。穿过 BBB 后,Lf-Cur-PSNPs 基本保持完整,对神经胶质瘤细胞(C6)的靶向作用更强。在暴露于 Lf-PSNPs 的小鼠体内成像研究中,Lf-PSNPs 能够有效地穿透 BBB 并优先在大脑中积累(比 PSNPs 高 2.39 倍)。此外,PSNPs 可在大脑中检测到 72 小时。这些数据表明,Lf-Cur-PSNPs 可以通过增强穿透 BBB 有效靶向和积累在神经胶质瘤中,因此应该进一步探索它们在 CNS 恶性肿瘤中的潜在应用。
