Description: AFN-1252, also known as AFN-12520000; API-1252; Debio-1452, is FASII Inhibitor which is potentially for the treatment of acute bacterial skin. AFN-1252 exhibits typical MIC(90) values of ≤0·015 μg/ml against diverse clinical isolates of S. aureus, oral absorption, long elimination half-live and efficacy in animal models. AFN-1252 efficiently blocked daptomycin-induced phospholipid decoy production, even in the case of isolates resistant to AFN-1252, which prevented the inactivation of daptomycin and resulted in sustained bacterial killing. In turn, daptomycin prevented the fatty acid-dependent emergence of AFN-1252-resistant isolates in vitr
