Działania biochem./fizjol.

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.

Daptomycin, a novel cyclic lipopeptide antibiotic against Gram-positive bacteria, is produced by Streptomyces roseosporus. Though its biosynthetic mechanism, structural shuffling and fermentation optimization have been extensively studied, little is understood about its production regulation at the transcriptional levels. Here we

Daptomycin is highly active against Staphylococcus aureus, including multidrug-resistant strains and those with reduced susceptibility to vancomycin. However, daptomycin-non-susceptible (Dap(NS)) strains [minimum inhibitory concentration (MIC) >1mg/L] have been derived clinically and in vitro. The mechanism(s) by which this occurs is
