A selective SOCE inhibitor that blocks CRAC current (ICRAC) without significant off-target potency or affinity.
Synta66 (S66) is a CRAC (Ca2+ release-activated Ca2+) channel inhibitor that blocks SOCE (store-operated Ca2+ entry) upon Ca2+ depletion from intracellular stores by thapsigargin in human vascular smooth muscle cells (VSMCs) with high potency (IC50 = 26 nM & 43 nM based on maximum Ca2+ level & rate of increase, respectly). Synta66 exhibits no affinity toward a range of receptors and ion channels (e.g. L-type Ca2+ channel) and does not affect TRPC1/5-mediated SOCE or store-operated non-selective cationic current. Leukocytes are reported to be less sensitive to CRAC inhibition by Synta66 (IC50 = 1.76 μM/HL-60, 1 ?M/Jurkat, 1.4 μM/rat RBL).

The aim was to advance the understanding of Orai proteins and identify a specific inhibitor of the associated calcium entry mechanism in vascular smooth muscle cells (VSMCs). Proliferating VSMCs were cultured from human saphenous veins. Intracellular calcium was measured using

Prolonged Ca(2+) entry through Ca(2+) release-activated Ca(2+) (CRAC) channels is crucial in activating the Ca(2+)-sensitive transcription factor NFAT, which is responsible for directing T cell proliferation and cytokine gene expression. To establish whether targeting CRAC might counteract intestinal inflammation, we

Mast cell activation involves cross-linking of IgE receptors followed by phosphorylation of the non-receptor tyrosine kinase Syk. This results in activation of the plasma membrane-bound enzyme phospholipase Cgamma1, which hydrolyzes the minor membrane phospholipid phosphatidylinositol 4,5-bisphosphate to generate diacylglycerol and

Dysregulation in calcium (Ca2+) signaling is a hallmark of chronic lymphocytic leukemia (CLL). While the role of the B cell receptor (BCR) Ca2+ pathway has been associated with disease progression, the importance of the newly described constitutive Ca2+ entry (CE)
The ubiquitous Ca2+ release-activated Ca2+ (CRAC) channel is crucial to many physiological functions. Both gain and loss of CRAC function is linked to disease. While ORAI1 is a crucial subunit of CRAC channels, recent evidence suggests that ORAI2 and ORAI3
