| Hazard Information | Back Directory | [Uses]
HMR 1556 is an inhibitor of the slow delayed rectifier potassium current, used in the monitoring and treatment of proarrythmia. | [Biological Activity]
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 HergKv1.3 (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 μMrespectively; guinea pig ventricular myocytes)being inefficient against L-type Ca2+ channel or rapidly delayed & inward rectifier currents (IKr & IK1) in guinea pig ventricular myocytesnor transient & sustained outward currentsI(to) & I(sus)in r at ventricular myocytes. | [storage]
