Bioactivity Comments
GSK-7975A completely inhibits calcium influx through CRAC channels in vitro [2]. GSK-7975A was used to show that CRAC channel activity is essential for mast cell and T cell function. The rat channel displays a similar pharmacology to human CRAC channels, so this compound is suitable for in vivo rat studies with translational potential to human.
