Replacement of the morpholinyl moiety in (S,E)-N-[1-(3-morpholinophenyl)ethyl]-3-phenylacrylamide (1) with heteroaryl groups led to the identification of (S,E)-N-1-[3-(6-fluoropyridin-3-yl)phenyl]ethyl-3-(2-fluorophenyl)acrylamide (5) as a potent KCNQ2 potassium channel opener. Among this series of heteroaryl substituted acrylamides, (S,E)-N-1-[3-(1H-pyrazol-1-yl)phenyl]ethyl-3-(2-fluorophenyl)acrylamide
(S,E)-N- [1-(3-吗啉代苯基)乙基] -3-苯基丙烯酰胺(1)中的吗啉基部分被杂芳基取代导致鉴定(S,E)-N-1- [ 3-(6-氟吡啶-3--3-基)苯基] -3-(2-氟苯基)丙烯酰胺(5)作为有效的KCNQ2钾通道开放剂。在这一系列杂芳基取代的丙烯酰胺中,(S,E)-N-1- [3-(1H-吡唑-1-基)苯基]乙基-3-(2-氟苯基)丙烯酰胺(9)具有平衡的效能和功效。描述了该系列丙烯酰胺的合成和KCNQ2开启剂活性。
