생화학적/생리학적 작용
HMR-1556 is a potent and selective blocker of the heteromeric KCNQ1-KCNE1 (KvLQT1-MinK) voltage-gated channel-mediated slowly activating K+ current (IKs IC50 = 120 nM in hKCNE1-transfected Xenopus oocytes; little or no inhibition of Herg, Kv1.3 (KCNA3), Kv1.5 (KCNA5), Kir2.1 (KCNJ2), HCN2 (BCNG2) current in respective oocyte transfectants). HMR-1556 is more potent than chromanol 293B (IKs IC50 = 34 nM and 2.1 μM, respectively; guinea pig ventricular myocytes), being inefficient against L-type Ca2+ channel or rapidly delayed & inward rectifier currents (IKr & IK1) in guinea pig ventricular myocytes, nor transient & sustained outward currents, I(to) & I(sus), in rat ventricular myocytes.
Potent and selective blocker of the heteromeric KCNQ1-KCNE1 (KvLQT1-MinK) voltage-gated channel-mediated slowly activating K+ current (Iks).

The chromanol HMR 1556 is a potent blocker of KvLQT1/minK potassium channels expressed in Xenopus oocytes. The compound is therefore a new class III antiarrhythmic drug with a distinct mechanism of action. However, the effect of HMR 1556 on atrial

Rationale: Arrhythmogenic cardiac alternans are thought to be an important determinant for the initiation of ventricular fibrillation. There is limited information on the effects of sympathetic nerve stimulation (SNS) on alternans in the intact heart and the conclusions of existing

[Ca2+ ]i enhanced rabbit ventricular slowly activating delayed rectifier K+ current (IKs ) by negatively shifting the voltage dependence of activation and slowing deactivation, similar to perfusion of isoproterenol. Rabbit ventricular rapidly activating delayed rectifier K+ current (IKr ) amplitude

Chromanol HMR 1556 [(3R,4S)-(+)-N-[3-hydroxy-2,2-dimethyl-6-(4,4,4-trifluorobutoxy)chroman-4-yl]-N-methylmethanesulfonamide], a novel inhibitor of the slow component of the delayed outward current in heart muscle cells (IKs), has been characterized in several in-vitro systems. mRNA encoding for the human protein minK was injected into Xenopus oocytes

Journal of cardiovascular pharmacology, 41(1), 140-147 (2002-12-25)
The slowly activating delayed rectifier potassium current (IKs) contributes prominently to ventricular repolarization of the cardiac action potential. Development of a selective IKs blocker is important for the elucidation of the physiologic and pathophysiologic relevance of IKs and the development
