had no effect. The 5 and 10% AP-BTH-LIP were the most effective in inhibiting Αβ42 fibril formation. Surprisingly, the AP-BTH-LIP, especially the 5% ones, demonstrated high interaction with brain endothelial cells and high capability to be transported across the BBB model. Taken together, the current results reveal that the 5% AP-BTH-LIP are of high interest as novel targeted theragnostic systems against
在体外评估了 2-苯并噻唑修饰的脂质体作为阿尔茨海默病治疗系统的潜力,使用修饰有两种 2-苯并噻唑的聚乙二醇化脂质体:(i) 未取代的 2-苯并噻唑 (BTH) 和 (ii) 2-(4-氨基苯基)苯并噻唑(AP-BTH)。合成了 BTH-lipid 和 AP-BTH-lipid 的脂质衍生物,用于插入脂质体膜。配制了含有三种不同浓度苯并噻唑(5%、10% 和 20%)的脂质体 (LIP),以及它们在血清蛋白存在下的稳定性、完整性以及它们抑制 β-淀粉样蛋白 (1-42) (Aβ42) 的能力肽聚集(通过圆二色性(CD)和硫代黄素T(ThT)测定)进行了评估。此外,还研究了一些 LIP 与血脑屏障 (BBB) 体外模型的相互作用。所有脂质体类型的范围在 92 和 105 nm 之间,除了较大的 20% AP-BTH-LIP (180 nm)。5% 和 10% AP-BTH-LIP 在 4 °C
