GSK864 is a cell penetrant, potent and selective allosteric inhibitor of isocitrate dehydrogenase 1 (IDH1) that potently inhibits intracellular 2-hydroxyglutarate (2-HG) production in HT-1080 cells. It appears that GSK864 binds to an allosteric binding site and locks WT and mutant IDH1s in a catalytically inactive conformation. GSK864 is a highly bioavailable analog of GSK321.

| 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.
