GSK864 is an isocitrate dehydrogenase 1 (IDH1) mutant inhibitor; inhibits IDH1 mutants R132C, R132H, and R132G with IC50 values of 8.8, 15.2 and 16.6 nM.

Name	GSK864
Synonyms	1H-Pyrazolo[4,3-c]pyridine-3,7-dicarboxamide, 1-[(4-fluorophenyl)methyl]-4,5,6,7-tetrahydro-N3-(4-methoxy-3,5-dimethylphenyl)-7-methyl-5-(1H-pyrrol-2-ylcarbonyl)-, (7S)- GSK864 (7S)-1-(4-Fluorobenzyl)-N3-(4-methoxy-3,5-dimethylphenyl)-7-methyl-5-(1H-pyrrol-2-ylcarbonyl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine-3,7-dicarboxamide

Description	GSK864 is an isocitrate dehydrogenase 1 (IDH1) mutant inhibitor; inhibits IDH1 mutants R132C, R132H, and R132G with IC50 values of 8.8, 15.2 and 16.6 nM.

Target	IC50: 8.8 nM (IDH1 mutants R132C), 15.2 nM (IDH1 mutants R132H), 16.6 nM (IDH1 mutants R132G)[1]
In Vitro	GSK864 inhibits 2-HG production in R132C IDH1 mutant HT1080 fibrosarcoma cells with an EC50 of 320 nM by LCMS/MS analysis[1].
In Vivo	Following intraperitoneal (IP) administration in CD-1 mice, significant concentrations of GSK864 are maintained in peripheral blood samples of mice for up to 24 hours. Analysis of BM cells for expression of markers of early differentiation reveals slightly increased numbers of huCD45+ CD38+ cells in R132C or R132H IDH1 mutant engrafted mice treated with GSK864[1].
Animal Admin	Mice: Mice receive GSK864 (213 mg/kg, 10 mL/kg) via intraperitoneal (ip) administration. IP formulation is PG:DMSO:PEG400:H2O (16.7:3.3:40:40). Serial blood samples (~0.030 mL) are collected via the femoral artery catheter at 15, 30, 45, 60, 120, 180 min following administration[1].
