GSK-5498A

Research use only, not for human use.

GSK-5498A is a potent, selective small molecule blocker of Calcium-Release Activated Calcium (CRAC) channel with IC50 of 1 uM.

GSK-5498A is a potent, selective small molecule blocker of Calcium-Release Activated Calcium (CRAC) channel with IC50 of 1 uM; completely inhibits calcium influx through CRAC channels, inhibits mediator release from mast cells, and pro-inflammatory cytokine release from T-cells from multiple human and rat preparations.

GSK-5498A (1 and 10 μM) inhibits calcium influx through CRAC channels in human embryonic kidney cells.GSK-5498A (1 nM-10 μM) inhibits the thapsigargin-evoked fluorescence signal (pIC50: 6.3) in Jurkat cells, measured using the calcium sensitive dye: Fluo4-AM.GSK-5498A (1 nM-10 μM) evokes concentration-dependent inhibition of Cytostim-evoked interferon-γ and IL-5 production in PBMCs.GSK-5498A (1 μM-10 μM) inhibits degranulation of rat tissue-resident mast cells.GSK-5498A (10 nM-10 μM) inhibits mouse and rat T-cell cytokine (IL-2) release.GSK-5498A (0-10 μM) shows high selectivity for CRAC channels over other ion channels, enzymes and G-protein coupled receptors.
