Daptomycin is a bactericidal antibiotic which works against a broad spectrum of Gram-positive bacteria and it can work both in-vitro and in-vivo. It is a cyclic lipopeptide and many antibiotic resistant strains can be inhibited by daptomycin, such as meticillin-resistant S. aureus (MRSA), vancomycin-intermediate S. aureus (VISA) and vancomycin-resistant S. aureus (VRSA).[1, 2]
The mode of action of Daptomycin would be through a calcium-dependent interaction with the cytoplasmic membrane, thus leading to the cell membrane depolarisation, ion loss and cell death.[2] Daptomycin can bind to the lipid tail of cell membrane of Gram-positive cells, then the following Ca2+ dependent insertion of daptomycin and oligomerization can cause a damage to the bacterial membrane potential, thus kills the cell very fast.[3]
