Pharmacodynamics of ClpP-Activating Antibiotic Combinations against Gram-Positive Pathogens.

ABSTRACT: It is often difficult to cure endocarditis, osteomyelitis, and device-associated infections caused by Gram-positive pathogens, despite therapy with clinically appropriate antibiotics. This may be due to antibiotic tolerance or resistance development. Acyldepsipeptides (ADEPs) are a class of bactericidal compounds active against a variety of clinically important Gram-positive bacteria, including staphylococci, streptococci, and enterococci. ADEPs activate caseinolytic protease P (ClpP), killing high-density, nondividing cultures of bacteria that are tolerant to approved classes of antibiotics. Acyldepsipeptide analog 4 (ADEP4) was active against a panel of drug-resistant Gram-positive pathogens in MIC assays, with no preexisting resistance detected. Killing of stationary-phase cultures was
