Cat.No. 2147 - Nicorandil | C8H9N3O4 | CAS No. 65141-46-0
Description: Kir6 (KATP) channel opener and NO donor
Chemical Name: N-[2-(Nitrooxy)ethyl]-3-pyridinecarboxamide

Biological Activity

Kir6 (KATP) channel opener and NO donor; antianginal agent. Preferentially activates SUR2B- versus SUR2A-containing Kir6 channels (EC50 values are 10 and > 500 μM respectively) and causes 1.6-fold increase in cardiac eNOS expression. Displays coronary and peripheral vasodilatory properties, reduces both pre- and after-load, and increases coronary blood flow. Also displays cardioprotective effects, possibly through ischemic preconditioning.
