Anwendung

Synta66 has been used:
  • as a Ca2+ release-activated calcium (CRAC) channel inhibitor to study its effects on ORAI isoforms
  • as an ORAI1 blocker to study its effects on the entry of Ca2+ in chronic lymphocytic leukemia (CLL) B cells
  • as a CRAC blocker to study its effects on the influx of Ca2+ by store-operated Ca2+ entry (SOCE) in enamel cells

Biochem./physiol. Wirkung

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

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)

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

Calcium (Ca2+) release-activated Ca2+ (CRAC) channels mediated by STIM1/2 and ORAI (ORAI1-3) proteins form the dominant store-operated Ca2+ entry (SOCE) pathway in a wide variety of cells. Among these, the enamel-forming cells known as ameloblasts rely on CRAC channel function
