    Rhodionin

    		Cholinesterase (ChE) Lipase Bacterial Cytochrome P450 Infection Metabolic Disease
    Rhodionin is an orally active, multifunctional antivirulence and cytoprotective agent that targets and inhibits Lipase, sortase A (SrtA), CYP2D6 (IC50=0.761 μM), AChE (IC50=2.43-57.5 μM), and DPPH free radicals (IC50=19.49 μM). Rhodionin is isolable from the roots of Rhodiola crenulata. Rhodionin reduces postprandial serum triglyceride levels in mice by inhibiting lipase activity. Rhodionin also binds directly to SrtA to inhibit its transpeptidase activity, thereby reducing the fibrinogen adhesion and surface protein A levels of MRSA, effectively inhibiting biofilm formation and protecting against MRSA-induced cell damage. Rhodionin improves the survival rate of infected mice without affecting MRSA growth, and finds wide application in studies related to hyperlipidemia, exogenous obesity, and pneumonia induced by methicillin-resistant Staphylococcus aureus (MRSA) .
