Cat. No. 4462
Chemical Name: N-[4-Bromo-2-(1H-tetrazol-5-yl-phen
Biological ActivityHuman ether-a-go-go (hERG) KV11.1 potassium channel activator. Activates the IKr current and displays antiarrhythmic activity. Exhibits potential dual mode of action at the hERG inhibitory site; may also act as a partial blocker of KV11.1 (hERG) channels. Displays selectivity over the key cardiac potassium ion channels, KV7.1 (KCNQ1), KV1.5, and KV4.3. Suitable for both in vitro and in vivo use.
