In this study, novel redox-sensitive nanoparticles based on xylan-lipoic acid (Xyl-LA) conjugate were developed for tumor targeted delivery of niclosamide (Nic) in cancer therapy. The niclosamide loaded xylan-lipoic acid conjugate nanoparticles (Xyl-LA/Nic NPs) showed redox responsive behaviour in presence of reductive glutathione (GSH), which indicate their suitability for intracellular drug release. The obtained Xyl-LA/Nic NPs exhibited uniform particle size (196 ± 1.64 nm), high loading capacity (~28.6 wt %) and excellent blood compatibility. The anticancer activity of the Niclosamide and the Xyl-LA/Nic NPs against the colon carcinoma cell lines (HCT-15, Colo-320) were evaluated by MTT assay and the overall results indicate that the Xyl-LA/Nic NPs significantly enhanced the therapeutic efficiency of niclosamide in cancer therapy.
在这项研究中，开发了基于木聚糖-硫辛酸（Xyl-LA）缀合物的新型氧化还原敏感纳米粒子，用于癌症治疗中尼氯柳胺（Nic）的肿瘤靶向递送。载有尼氯柳胺的木聚糖-硫辛酸缀合物纳米粒子（Xyl-LA/Nic NPs）在还原性谷胱甘肽（GSH）存在下表现出氧化还原响应行为，表明它们适合细胞内药物释放。所得到的 Xyl-LA/Nic NPs 表现出均匀的粒径（196 ± 1.64nm）、高载药量（~28.6wt%）和优异的血液相容性。通过 MTT 测定评估了尼氯柳胺和 Xyl-LA/Nic NPs 对结肠癌细胞系（HCT-15、Colo-320）的抗癌活性，结果表明 Xyl-LA/Nic NPs 显著提高了尼氯柳胺在癌症治疗中的治疗效率。
