Abstract

The biological activity of neohesperidin (NH, a flavanone glycoside) is limited due to instability in the physiological environment. Thus, the current study aimed to explore the protective effect of NH-loaded pectin-chitosan decorated liposomes (P-CH-NH-NL) against palmitic acid (PA)-induced hepatic oxidative injury in L02 cells. The particles were characterized using DLS, TEM, HPLC, DSC, and cellular uptake study. Then, the protective effect of NH-loaded liposomal systems (NH-NLs) against PA-induced oxidative injury was evaluated in terms of cell viability study, intracellular ROS, superoxide ions (O), MMP, and cellular GSH determination. Our results exhibited that NH-NLs significantly lessened the PA-induced hepatic oxidative injury in L02 cells via decreasing ROS and O generation, reducing MMP collapse, and attenuating GSH reduction, whereas the free NH samples were ineffective. Furthermore, the coated NH-NLs were more effective than that of uncoated nanoliposome. Overall, our study confirmed that P-CH-NH-NL was capable of reducing PA-induced hepatic oxidative injury. Therefore, the pectin-chitosan decorated nanoliposome can be considered as an efficient delivery system for enhancing cellular uptake of lipophilic compound with controlled release and greater biological activity.

摘要

由于在生理环境中不稳定,新橙皮苷(NH,一种黄烷酮糖苷)的生物活性有限。因此,本研究旨在探索负载 NH 的果胶-壳聚糖修饰脂质体(P-CH-NH-NL)对 L02 细胞中棕榈酸(PA)诱导的肝氧化损伤的保护作用。采用 DLS、TEM、HPLC、DSC 和细胞摄取研究对颗粒进行了表征。然后,通过细胞活力研究、细胞内 ROS、超氧阴离子(O)、MMP 和细胞 GSH 测定,评估了负载 NH 的脂质体系统(NH-NLs)对 PA 诱导的氧化损伤的保护作用。结果表明,NH-NLs 通过减少 ROS 和 O 的产生、降低 MMP 崩溃和减轻 GSH 减少,显著减轻了 L02 细胞中由 PA 引起的肝氧化损伤,而游离 NH 样品则无效。此外,包被的 NH-NLs 比未包被的纳米脂质体更有效。总的来说,我们的研究证实了 P-CH-NH-NL 能够减轻 PA 诱导的肝氧化损伤。因此,果胶-壳聚糖修饰的纳米脂质体可以被认为是一种有效的给药系统,用于增强具有控制释放和更高生物活性的亲脂性化合物的细胞摄取。
