A series of novel spirocyclic benzopyran imidazolones were synthesized as rigid analogues of cromakalim. These compounds cause a dose-dependent membrane hyperpolarization of A10 rat aorta cells. This hyperpolarization was blocked by pretreatment with glyburide, indicating that the spirocyclic benzopyran imidazolones were acting by increasing the open probability of ATP-sensitive potassium channels
