Abstract

Although malaria has been effectively controlled, it still poses a threat to global health. Artemisinins are the first-line antimalarial drugs. However, their therapeutic efficacy is significantly limited by poor solubility and short biological half-life. To overcome these limitations and enhance drug accumulation in , we developed a glucose-functionalized redox-responsive dihydroartemisinin (DHA) prodrug nanosystem (D@GLU-PMs-SS). The nanosystem was prepared by using DHA-dithiodipropionic acid-octadecylamine prodrug and D-α-Tocopherol polyethylene glycol 1000 succinate-arbutin conjugate. The resultant D@GLU-PMs-SS exhibited excellent stability under conditions of storage and physiological environment. D@GLU-PMs-SS could be activated by glutathione (GSH), leading to the dissociation of nanoparticles and subsequent release of free DHA. experiments revealed that the host erythrocyte uptake of glucose-functionalized nanoparticles was significantly enhanced GLUT-mediated transport. Cellular experiments illustrated that D@GLU-PMs-SS effectively reduced GSH concentrations in . Furthermore, D@GLU-PMs-SS displayed remarkable efficacy in inhibiting the growth of while maintaining biosafety. Overall, this study developed a strategy to enhance the targeting of nanoparticles to improve their therapeutic efficacy against malaria, warranting further investigation in clinical trials.

摘要

尽管疟疾已得到有效控制,但它仍然对全球健康构成威胁。青蒿素是一线抗疟药物。然而,它们的治疗效果因溶解度差和生物半衰期短而受到显著限制。为了克服这些限制并增强药物在体内的蓄积,我们开发了一种葡萄糖功能化的氧化还原响应型二氢青蒿素(DHA)前药纳米系统(D@GLU-PMs-SS)。该纳米系统是通过使用DHA-二硫代二丙酸-十八烷基胺前药和D-α-生育酚聚乙二醇1000琥珀酸酯-熊果苷共轭物制备的。所得的D@GLU-PMs-SS在储存和生理环境条件下表现出优异的稳定性。D@GLU-PMs-SS可被谷胱甘肽(GSH)激活,导致纳米颗粒解离并随后释放游离的DHA。实验表明,葡萄糖功能化纳米颗粒通过GLUT介导的转运显著增强了宿主红细胞摄取。细胞实验表明,D@GLU-PMs-SS有效降低了细胞内的GSH浓度。此外,D@GLU-PMs-SS在抑制疟原虫生长的同时保持生物安全性方面显示出显著疗效。总体而言,本研究开发了一种增强纳米颗粒靶向性的策略,以提高其抗疟治疗效果,值得在临床试验中进一步研究。
