Daptomycin

Daptomycin   is the first entry of a new class of cyclic lipopeptide antibiotics that disrupts multiple aspects of bacterial membrane function including disruption of membrane potential and amino acid transport, inhibition of lipoteichoic acid synthesis and inhibition of peptidoglycan synthesis. It is indicated for the treatment of complicated skin and skinstructure infections (cSSSI) caused by a range of Gram-positive bacteria. This is distinct from previous classes of antibiotics that inhibit bacterial cell wall biosynthesis, bacterial DNA replication, and folate coenzyme biosynthesis. Due to this unique mechanism, cross-resistance has not been noted with any other class of antibiotics. It is produced by the fermentation of Streptomyces roseporus.
