产品描述:
A-54556A is an acyldepsipeptide (ADEP) antibiotic that has been found in Streptomyces hawaiiensis.{24688} It is active against B. subtilis, S. pyogenes, and E. faecalis, as well as penicillin-resistant S. pneumoniae, vancomycin-resistant E. faecium, and methicillin-resistant S. aureus (MRSA; IC50s = 0.2, 0.4, 0.4, 1.6, 0.4, and 6.3 µg/ml, respectively). It binds to and activates caseinolytic protease P (ClpP), inducing degradation of β-casein by the B. subtilis ClpP in an ATPase-independent manner when used at concentrations of 2.5 and 5 µg/ml.
