Establishing the Structure-Activity Relationship of Daptomycin.

Daptomycin is effective in treating infections caused by antibiotic-resistant Gram-positive pathogens, including methicillin-resistant (MRSA), vancomycin-resistant (VRE), and vancomycin-resistant (VRSA). Due to its distinct mechanism of action toward multidrug-resistant bacteria, daptomycin provides an attractive structural motif to generate new daptomycin-based antibiotics to combat the problem of bacterial resistance. In this study, we used the total synthesis method to produce daptomycin analogues with a variety in terms of types and sites of modifications.
