摘 要:硝酸盐是一种机体不可或缺的营养物质,已应用于多种疾病的预防和治疗研究.但由于半衰期短,硝酸盐的临床应用受限.为了提高硝酸盐可用性,突破传统的依赖大规模高通量生物实验的药物配伍研发瓶颈,本文报道了一种基于群体学习方法的药物配伍预测系统,该系统预测维生素C为与硝酸盐配伍的首选药物.通过采用微囊化技术,筛选并优化缓释制剂工艺,以维生素C、硝酸钠及壳聚糖3000为芯材,果胶与羧甲基纤维素钠为壁材制备硝酸盐纳米颗粒,命名为耐瑞特(Nanonitrator).耐瑞特的更长循环期显著提高了硝酸盐对放射性唾液腺损伤的疗效,同时维持了安全性.相同剂量的耐瑞特比硝酸盐(包含或不包含维生素C)可显著增强PI3K-Akt信号通路转导,更好地维持细胞内稳态,提示了其广泛的临床应用潜力.此外,本文还提供了一种将无机化合物加入缓释纳米颗粒的新方法.Inorganic nitrate is an indispensable nutrient that has been used in experimental studies for the prevention and treatment of several diseases.However,the short half-life of nitrate limits its clinical application.To increase the usability of nitrate and overcome the challenges of traditional combination drug discovery through large-scale high-throughput biological experiments,we developed a swarm learning-based combination drug prediction system that identified vitamin C as the drug of choice to be combined with nitrate.Employing microencapsulation technology,we used vitamin C,sodium nitrate,and chitosan 3000 as the core materials to prepare a nitrate nanoparticle,which we named Nanonitrator.The longcirculating delivery ability of nitrate by Nanonitrator significantly increased the efficacy and effect duration of nitrate in irradiation-induced salivary gland injury,without compromising safety.Nanonitrator at the same dose could better maintain intracellular homeostasis than nitrate(with or without vitamin C),emphasizing its potential for clinical use.More importantly,our work provides a method for incorporating inorganic compounds into sustained-release nanoparticles.
