Verwenden
CRAC Channel Inhibitor BTP2 is a cell-permeable analog of BTP. A pyrazole derivative which inhibits activation-induced Ca2+ influx in rats.
Allgemeine Beschreibung
A cell-permeable pyrazole that acts as a more potent blocker of Stim1 and Orai1-coupled CRAC (Ca2+ release-activated Ca2+) channel-mediated SOCE (store-operated Ca2+ entry) in RBL-2H3 cells (IC50 = 590 nM by Fura-2; peak current density pA/pF = -1.13 and -7.50, respectively, with or without 3 μM BTP2/Pyr2 by whole cell clamp) than the transient receptor potential cation channel TRPC3-mediated ROCE (receptor-operated Ca2+ entry) inTRPC3-expressing HEK293 cells (IC50 = 4.21 μM by Fura-2; pA/pF = -1.54 and -18.50, respectively, with or without 3 μM BTP2/Pyr2). A great complement to Pyr 3 (Cat. No. 648490), Pyr6, and Pyr10 in Ca2+ signaling studies.
Biochem/physiol Actions
YM-58483 is a selective Ca++ release-activated Ca++ (CRAC) [a.k.a. store-operated Ca++ (SOC) channels] that mediate Ca++ influx in T cells and other inflammatory cells. CRAC channel inhibitors have potential clinical applications in autoimmune disease, transplant rejection, allergic airway inflammation and bronchial asthma. YM-58483 is also promoted as a tool for CRAC studies; may be used as a gold standard.
