Application of berberine-loaded albumin nanoparticles in infections of traumatic wounds.

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 (S.aureus) activity, which gives some new insights into the preparation and development of anti-infectives for Chinese medicine.
