A series of 4-(cyclic amido)-2H-naphtho[1,2-b]pyrans related to cromakalim (1) has been prepared and their vasorelaxant activities on isolated rat thoracic aorta precontracted with phenylephrine have been evaluated. The relaxant mechanism of 3a was found not through ATP-sensitive K(+) channels as cromakalim, but through opening voltage-sensitive K(+) channels.
制备了一系列与cromakalim(1)相关的4-(环状酰胺基)-2H-萘并[1,2-b]吡喃,并评估了它们对苯肾上腺素预收缩的离体大鼠胸主动脉的血管舒张活性。发现3a的弛豫机理不是通过ATP敏感的K(+)通道作为cromakalim,而是通过打开电压敏感的K(+)通道。
