Afabicin  (Synonyms: Debio 1450; AFN-1720)

Afabicin (Debio 1450) is the proagent of Debio1452, specifically targeting staphylococci without significant activity against other Gram-positive or Gram-negative species. Debio1452 is an inhibitor FabI, an enzyme critical to fatty acid biosynthesis in staphylococci.

Afabicin (Debio1450) is the prodrug of Debio1452, specifically targeting staphylococci without significant activity against other Gram-positive or Gram-negative species. Debio1452 inhibits FabI, an enzyme critical to fatty acid biosynthesis in staphylococci. Debio1452 is highly active against staphylococci isolates, with MIC₅₀ and MIC₉₀ values of 0.015 μg/mL and 0.12 μg/mL, respectively. Debio1452 also inhibits S. aureus, with MICs of ≤0.12 μg/mL and MIC₅₀ and MIC₉₀ values of 0.004 μg/mL and 0.008 μg/mL, respectively^[1].
