AFN-1252
Based on 12 publication(s) in Google Scholar
AFN-1252 is an orally active and selective inhibitor of FabI, an essential enzyme in fatty acid biosynthesis in Staphylococcus spp. AFN-1252 exhibits exquisite and highly selective activity against Staphylococcus spp. AFN-1252 exhibits typical MIC90 values of ⩽0.015 μg/ml against diverse clinical isolates of S. aureus. AFN-1252 is efficacious in a mouse model of septicemia providing 100% protection from an otherwise lethal peritoneal infection of S. aureus Smith.
