Biological target:
GSK321 is a potent and selective IDH1 mutant inhibitor.
In vitro activity:
Mechanistic cellular activity of GSK321 and GSK990 was evaluated in HT-1080 fibrosarcoma cells, which harbor an R132C IDH1 mutation and have markedly elevated levels of 2-hydroxyglutarate (2-HG). After 24 h of treatment with the compounds, GSK321 potently inhibited intracellular 2-HG production in HT-1080 cells, with a half-maximal effective concentration (EC50) of 85 nM by LC/MS/MS analysis (Fig. 1b).

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
