Cell culture and mouse studies suggest combining the antibiotic acyldepsipeptide 4 (ADEP4) with rifampicin could help eradicate biofilms. In stationary methicillin-resistant S. aureus (MRSA), ADEP4 activated the clpP protease and led to extensive protein degradation. In culture and a mouse model of chronic infection, ADEP4 plus rifampicin eradicated MRSA biofilms, whereas rifampicin alone did not. Next steps include additional tests on ADEP4 plus other antibiotics for toxicity and efficacy.
Rifampicin is a generic antibiotic (see ClpPing persistence, page 4).
