生物活性
描述 DCPIB is a selective, reversible and potent inhibitor of VRAC. DCPIB voltage-dependently activates the potassium channels TREK1 and TRAAK, and inhibits TRESK, TASK1, and TASK3 (IC50 values of 0.14, 0.95, and 50.72 μM, respectively). DCPIB is also a selective and swelling-induced blocker of chloride current with an IC50 value of 4.1 μM. DCPIB is an effective tool to study the structure-function of K2P channels. DCPIB at a concentration of 10 μM activates TREK1 and enhances TRAAK currents in COS-7 cells[1][2]. At the same concentration, DCPIB significantly and reversibly inhibited TRESK current in COS-7 cells with an IC50 of 0.14 μM[1]. While acting for 3 hours, DCPIB inhibited LPS-induced MAPK activation in BV2 cells[3].
