MOA. Mupirocin is an antibacterial agent active against a wide range of Gram-positive bacteria including methicillin-resistant Staphylococcus aureus. It is also active against certain Gram-negative bacteria. Mupirocin inhibits bacterial protein synthesis by reversibly and specifically binding to bacterial isoleucyl transfer-RNA synthetase. Due to this unique mode of action, mupirocin demonstrates no in vitro cross-resistance with other classes of antimicrobial agents.
