RO2959 hydrochloride 是一种有效的选择性 CRAC 通道抑制剂，IC₅₀ 为 402 nM。RO2959 hydrochloride 是由 Orai1/Stim1 通道介导的钙存储进入 (SOCE) 的有效阻滞剂，IC₅₀ 为 25 nM。RO2959 hydrochloride 还是人 IL-2 产生的有效抑制剂，有效阻断 T 细胞受体触发的基因表达和 T 细胞功能途径。

RO2959 hydrochloride is a potent and selective CRAC channel inhibitor with an IC 50 of 402 nM. RO2959 hydrochloride is a potent blocker of store operated calcium entry (SOCE) mediated by Orai1/Stim1 channels with an IC 50 of 25 nM. RO2959 hydrochloride is also a potent inhibitor of human IL-2 production, and potently blocks T cell receptor triggered gene expression and T cell functional pathways.

IL-2 CRAC channel 402 nM (IC50)

RO2959 inhibits Orai1 and Orai3 with IC50 values of 25 nM and 530 nM, respectively. RO2959 blocks store operated calcium entry (SOCE) in activated CD4+T lymphocytes with an IC50 value of 265 nM.
RO2959 is a potent SOCE inhibitor that blocks an IP3-dependent current in CRAC-expressing RBL-2H3 cells and CHO cells stably expressing human Orai1 and Stim1, as well as SOCE in human primary CD4 T cells triggered by either T cell receptor (TCR) stimulation or thapsigargin treatment. RO2959 completely inhibits cytokine production as well as T cell proliferation mediated by TCR stimulation or MLR (mixed lymphocyte reaction). has not independently confirmed the accuracy of these methods. They are for reference only.
