Biokémiai/fiziológiai hatások

Potent and selective TASK-1 potassium channel blocker that induces lasting respiratory alkalosis and stimulates breathing in anesthetized rats.




A1899 is a highly potent and selective non-voltage-dependent two-pore domain potassium channel K 2P 3.1 blocker (TASK-1, KCNK3, IC50 = 7 nM in CHO cells) with 10-fold selectivity over TASK-3 and much reduced or little potency towards TASK-2/4 (>8 µM in Xenopus oocytes) and other potassium channels. A1899 specifically blocks TASK-1 currents by 74% in Xenopus oocytes at 100 nM via an open-channel block mechanism. A1899 induces lasting respiratory alkalosis and stimulates breathing in anesthetized rats in vivo (5-25 mg/kg, i.v.). Also mitigates the endothelin-1 induced prolonged action potential duration in cardiomyocytes (at 200 nM).
