ZD0947 is potent ATP-sensitive K+ channels (KATP channels) opener. ZD0947 is an effective activator of smooth muscle-type KATP channels (SUR2B/Kir6.1 and SUR2B/Kir6.2) but is a partial antagonist of pancreatic-type KATP channels (i.e. SUR1/Kir6.2) and cardiac-type KATP channels (i.e. SUR2A/Kir6.2). ZD0947 potently inhibits carbacho-induced contraction in the strips of human detrusor.
