3β-Hydroxyurs-12,19-dien-28-oic acid Usage And Synthesis

Biological Activity

Sanguisorbigenin is a natural antibacterial agent that inhibits methicillin-resistant S. aureus (MRSA)[1]. The minimal inhibitory concentration values of Sanguisorbigenin against six strains of S. aureus are in the range of 12.5-50 μg/mL[1]. The expression of blaR1, mecA and blaZ is significantly inhibited in MRSA in a dose-dependent manner when it is treated with sub-MIC (1.56-6.25 μg/mL) concentrations of Sanguisorbigenin. Sanguisorbigenin remarkably reduces the gene expression of mecA. Sanguisorbigenin has a potent antibacterial effect and could effectively reverse the sense of antibiotics by inhibiting the mecA expression and decrease PBP2a expression[1].
