XE 991二盐酸盐是KCNQ电压门控钾通道的有效和选择性阻滞剂。阻止KCNQ2 | +3 | / M电流(IC | 50 | = 0.6-0.98μM)和KCNQ1同系通道(IC | 50 | = 0.75μM),但对KCNQ1 / minK通道的效力较弱(IC | 50 | = 11.1 (μM)。 应用: XE-991已被利用KCNQ(Kv7.2 / 7.3)抑制剂,以检查M电流抑制是否影响催产素受体(TGOT)介导的去极化。也曾作为 KCNQ 抑制剂用于研究河豚毒素(TTX)存在时小鼠胆碱能中间神经元(ChIs)膜电位超射/欠射的离子机制。 XE 991 dihydrochloride is a potent and selective blocker of KCNQ voltage-gated potassium channels. Blocks KCNQ2|+3|/M-currents (IC|50|= 0.6-0.98 μM) and KCNQ1 homomeric channels (IC|50|= 0.75 μM) but is less potent against KCNQ1/minK channels (IC|50|= 11.1 μM).
