产品详情
生物活性:
DCPIB is a selective, reversible and potent inhibitor of volume-regulated anion channels (VRAC). DCPIB voltage-dependently activates potassium channels TREK1 and TRAAK, and inhibits TRESK, TASK1 and TASK3 (IC50s: 0.14, 0.95, 50.72 μM, respectively). DCPIB is also a selective blocker of swelling-induced chloride current (ICl,swell), with an IC50 of 4.1 μM. DCPIB is a useful tool for investigating structure-function studies of K2P channels.

体内研究:
LDN-212854 (脑室内输注,1 mM,10 μL) 抑制 rMCAO 大鼠的小胶质细胞激活并改善神经元损伤。Animal Model:Reversible middle cerebral artery occlusion (rMCAO) model
Dosage:1 mM, 10 μL
Administration:Administered manually for 20s by intracerebroventricular infusion
Result:Diminished Pyramidal neurons injury induced by rMCAO in the CA1 region.

体外研究:
DCPIB (10 μM) 在 COS-7 细胞中激活 TREK1 并增强 TRAAK 电流。 DCPIB (10 μM) 在 COS-7 细胞中显著且可逆地抑制 TRESK 电流,具有 IC50 为 0.14 μM。 DCPIB (10 μM) 显示出对 ICl,swell 的选择性并且没有显著对 CPAE 细胞中 ICl,Ca 的抑制作用。 DCPIB (10 μM,5 分钟) 对减弱心肌细胞随后的肿胀没有影响。 DCPIB (10 μM,3 h) 抑制 BV2 细胞中 LPS 诱导的 MAPK 激活。
