Anti-MRSA agent 39

Anti-MRSA agent 39 is an orally active ClpX modulator that binds Staphylococcus aureus caseinolytic protease X (SaClpX) with high affinity (Kd = 3.6 μM) . Anti-MRSA agent 39 exerts antibacterial effects through temperature-dependent inhibition of cell division. Anti-MRSA agent 39 elicits profound metabolic dysregulation in methicillin-resistant Staphylococcus aureus (MRSA), manifesting as significantly reduced ATP levels, elevated reactive oxygen species (ROS), and decreased NAD+/NADH ratio, and accelerates bacterial lysis rates in MRSA ATCC 33591. Anti-MRSA agent 39 significantly increases the proportion of MRSA cells in the mitotic phase, and the cells exhibit obvious morphological abnormalities. Anti-MRSA agent 39 can be used for the study of invasive MRSA infections[1].
