Daptomycin

Daptomycin is a naturally occurring cyclic lipopeptide produced by the soil saprotroph S. roseosporus that is effective against resistant Gram-positive bacteria (MIC90s range from 0.25-16 mg/L). It binds to bacterial plasma membranes to disrupt multiple aspects of function, including altering membrane potential and redirecting proteins essential for cell division and cell wall synthesis.Formal Name: 2,2'-((3S,6S,9R,15S,18R,21S,24S,30S,31R)-30-((S)-2-((R)-4-amino-2-((S)-2-decanamido-3-(1H-indol-3-yl)propanamido)-4-oxobutanamido)-3-carboxypropanamido)-3-(2-(2-aminophenyl)-2-oxoethyl)-24-(3-aminopropyl)-6-((R)-1-carboxypropan-2-yl)-9-(hydroxymethyl)-18,31-dimethyl-2,5,8,11,14,17,20,23,26,29-decaoxo-1-oxa-4,7,10,13,16,19,22,25,28-nonaazacyclohentriacontane-15,21-diyl)diacetic acid.
