Chemical Name: N-(1-Oxodecyl)-L-tryptophyl-D-asparaginyl-L-α-aspartyl-L-threonylglycyl-L-ornithinyl-L-α-aspartyl-D-alanyl-L-α-aspartylglycyl-D-seryl-(3R)-3-methyl-L-α-glutamyl-α,2-diamino-γ-oxo-benzene butanoic acid (13-4) lactone
Biological ActivityDaptomycin is a lipopeptide, calcium-dependent antibiotic. Exhibits potent bacteriocidal activity against most gram-positive bacteria in vitro and in vivo, including antibiotic-resistant strains such as MRSA and VRE. Disrupts plasma membrane function; activity results in membrane depolarization leading to inhibition of protein, DNA and RNA synthesis.
