Biological Activity

Gepotidacin (GSK2140944) is a novel, potentially first-in-class, orally active triazaacenaphthylene antibiotic and type II topoisomerase (Topo II) inhibitor.Gepotidacin can selectively inhibit bacterial DNA replication by acting on DNA gyrase (GyrA) and topoisomerase IV (ParC).

Chemical Information
Molecular Weight 448.52
Formula C24H28N6O3
CAS Number 1075236-89-3
Form Solid
Solubility (25°C) DMSO 7.14 mg/mL
Storage -20°C
Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
