近期,中国科学技术大学的科研团队开发了一种新型口服抗生素递送载体,可高效促进抗生素的口服吸收,同时有效降低抗生素对肠道菌群稳态的破坏。相关成果在《Nature Biomedical Engineering》发表,论文的标题为“Glucosylated nanoparticles for the oral delivery of antibiotics to the proximal small intestine protect mice from gut dysbiosis”。
研究团队利用钠离子依赖性葡萄糖转运体1(SGLT1)在近端小肠特异性高表达的特性,设计合成了葡萄糖修饰的阳离子纳米载体(PGNPs)递送抗生素,并在小鼠实验中证实这种载体能促进抗生素在小肠中高效吸收,增强药物疗效,有效防止抗生素进入大肠,大大降低对肠道菌群的破坏作用以及由此造成的疾病风险和抗生素耐药基因的积累。
该研究有望避免当前口服抗生素对人体的两大副作用,包括破坏肠道菌群造成慢性疾病以及肠道耐药细菌、耐药基因的积累,具有重要的临床转化潜力。该研究成果已申请PCT发明专利。
