Molarity Calculator

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.

Description

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[1][2].

In Vitro

AFN-1252 is extremely potent against clinical isolates of S. aureus (MIC90, 0.015 μg/ml) and coagulase-negative staphylococci (MIC90, 0.12 μg/ml)[2]

In Vivo

AFN-1252 (0.03-3 mg/kg; oral gavage; single dose) is efficacious in a mouse model of septicemia, with 100% survival obtained with a single oral dose of 1 mg/kg[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Female 5- to 6-week-old CD-1 mice (18 to 22 g) with S. aureus Smith bacterial inoculum[2]
Dosage: 0.03, 0.1, 0.3, 1, 3 mg/kg
Administration: Oral gavage; single dose
Result: Was efficacious in a mouse model of septicemia, with 100% survival obtained with a single oral dose of 1 mg/kg.
The calculated ED50s (95% confidence limits) were 0.15 (0.11 to 0.21) mg/kg.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
