In recent years, the morbidity of infections in traumatic wounds has been on the increase. There are not many kinds of drugs for clinical treatment of infections, and their efficacy and safety are limited. Plant antimicrobial drugs are increasingly popular in mainstream medicine due to the challenges of traditional antibiotics abuse. Berberine has a scavenging effect on infections, however, berberine was restricted from using as a drug preparation with poor stability and bioavailability. Due to the low toxicity of nanoparticles, the green-synthetic, size-controlled approach of nanoparticles has been paid more attention. Therefore, based on the intermolecular disulfide bond network platform built earlier, we designed and developed a strategy to assemble molecular bovine serum albumin into large-sized nanostructures through the reconstructed intermolecular disulfide bond and hydrophobic interaction, and berberine with poor water solubility was encapsulated in it. Nanoassembly with bovine serum albumin increased biostability of berberine and significantly improved its activity against Staphylococcus Aureus () activity, which gives some new insights into the preparation and development of anti-infectives for Chinese medicine.
近年来,创伤伤口感染的发病率一直在上升。临床上用于治疗感染的药物种类不多,其疗效和安全性有限。由于传统抗生素滥用带来的挑战,植物抗菌药物在主流医学中越来越受欢迎。黄连素对感染有清除作用,然而,黄连素因其稳定性和生物利用度差而被限制用作药物制剂。由于纳米颗粒的低毒性,纳米颗粒的绿色合成、尺寸可控方法受到了更多关注。因此,基于早期构建的分子间二硫键网络平台,我们设计并开发了一种策略,通过重建分子间二硫键和疏水相互作用,将分子牛血清白蛋白组装成大尺寸纳米结构,并将水溶性差的黄连素包裹在其中。与牛血清白蛋白的纳米组装提高了黄连素的生物稳定性,并显著提高了其对金黄色葡萄球菌的活性,这为中药抗感染药物的制备和开发提供了一些新的见解。
