Description

Biochem/physiol Actions

Daptomycin is a natural cyclic lipopeptide antibiotic found in Streptomyces roseosporus. It is has been found to be effective in treating infections caused by aerobic Gram-positive bacteria. Daptomycin inhibits many antibiotic resistant strains such as methicillin-resistant S. aureus (MRSA), vancomycin-intermediate S. aureus (VISA) and vancomycin-resistant S. aureus (VRSA).

The mode of action of daptomycin is quite different from that of any other antibiotic. Daptomycin binds to bacterial membranes and causes a rapid depolarization of membrane potential. This loss of membrane potential causes inhibition of protein, DNA, and RNA synthesis, which results in bacterial cell death.
