摘要
Due to the bacteria resistant to various first-line antibiotics, it is urgent to develop efficient antibiotic alternatives and formulate multidimensional strategies. Herein, supramolecular Chinese medicine nanoparticles are synthesized by self-assembly of berberine (BBR) and chlorogenic acid (CGA), which exhibit higher inhibitory effect against Staphylococcus aureus and multidrug-resistant Staphylococcus aureus (MRSA) than ampicillin, oxacillin, BBR, CGA, as well as mixture of BBR and CGA (minimum inhibitory concentration, MIC = 1.5 µM). The inhibition by BBR/CGA nanoparticles (2.5 µM) reaches 99.06% for MRSA, which is significantly higher than ampicillin (29.03%). The nanoparticles with 1/2 MIC can also synergistically restore the antimicrobial activity of ampicillin against MRSA. Moreover, in vivo therapeutic outcome in the murine skin wound infection model suggests that the nanoparticles are able to promote wound healing. This study provides new insights in the application of Chinese medicines self-assembly for MRSA inhibition, as well as solutions for potential persistent clinical infections and drug deficiencies. Supramolecular nanoparticles are prepared from biocompatible Chinese medicine molecules. The nanoparticles exhibit higher inhibitory effect against Staphylococcus aureus and multidrug-resistant Staphylococcus aureus. The excellent performances demonstrate their great potential utility to reduce environment-related health risks.
