Multi-omics revealed antibacterial mechanisms of licochalcone A against MRSA and its antimicrobic potential on pork meat

Licorice flavonoids (LFs) exhibit potent antibacterial activities against Gram-positive bacteria. However, the related mechanism remains unclear. This study aims to illustrate the mechanisms of licochalcone A (LA), a main flavonoid in LFs, against methicillin-resistant Staphylococcus aureus (MRSA)....

description Licorice flavonoids (LFs) exhibit potent antibacterial activities against Gram-positive bacteria. However, the related mechanism remains unclear. This study aims to illustrate the mechanisms of licochalcone A (LA), a main flavonoid in LFs, against methicillin-resistant Staphylococcus aureus (MRSA). The anti-MRSA effect of LA was comprehensively investigated by a combination of proteomics and metabolomics studies. Meanwhile, LA was loaded in glycyrrhizin (GA) micelles (GA@LA micelles) to improve its water solubility. The results demonstrated that LA could disrupt the arginine metabolism and cause the accumulation of intracellular ROS in MRSA. In addition, LA could inhibit the expression of glucokinase in MRSA, which affect the synthesis of ATP, fatty acids, and peptidoglycan. GA@LA micelles have the latent ability to inhibit the growth of MRSA on fresh pork.
