The human ether-a-go-go-related gene (hERG) potassium channel conducts rapid delayed rectifier potassium currents (IKr) and contributes to phase III cardiac action potential repolarization. Drugs inhibit hERG channels by binding to aromatic residues in hERG helixes. Berberine (BBR) has multiple actions. and its hydrogenated derivative dihydroberberine (DHB) is a potential candidate fo... https://www.elphonsolam.com/product-category/melts/
