Cyclohexane derivatives useful as potassium channel openers.
摘要
To provide a novel cyclohexane derivative, a cyclohexane derivative is defined by the formula (I) or a pharmacologically acceptable salt thereof: <CHEM> (wherein R<1> and R<2> may be the same or different from each other and each represents hydrogen or lower alkyl; R<3> represents optionally substituted aryl or optionally substituted heteroaryl; X represents oxygen or sulfur; and Y represents a group represented by the formula: <CHEM> or the like). The compound of the present invention is useful as a preventive and therapeutic agent for diseases against which a potassium channel opening action is efficacious.
