ML-T531

A potent, selective hERG potassium channel (Kv11.1) activator with EC50 of 3.13 uM; exhibits no potentiation for KCNQ1 and KCNE1, and no noticeable effects on other cardiac channels including Cav1.2, Kir2.1, Nav1.5, and Kv4.3; significantly potentiates hERG steady-state currents and tail currents in CHO cells at 10 uM, enhances voltage-dependent potassium current amplitudes in the presence of an Iks-specific inhibitor chromanol 293B; potentiates native potassium currents in iPSC-derived cardiomyocytes, shortens the APD90 of LQT1 cardiomyocytes with EC50 of 5.71 uM, normalizes the disease phenotype of cardiomycytes derived from a patient with LQT1.
