Compounds which function as modulators, particularly, openers, of human KCNQ potassium channel proteins or polypeptides, particularly, central nervous system (CNS)-located KCNQ potassium channels, and heteromultimers thereof, and their use in the treatment of migraine are provided by the present invention. One novel type of potassium channel polypeptide openers provided by the present invention is the fluorooxindole compounds, described for the first time as therapeutics for the treatment of migraine by preventing the asynchronous firing of neurons. Other KCNQ potassium channel opener compounds that are also useful in the treatments of the invention include 2,4-disubstituted pyrimidine-5-carboxamide derivatives. One or more of the compounds according to the present invention may be utilized alone, in combination, or in conjunction with other treatment modalities for reducing, ameliorating and/or alleviating migraine or diseases similar to, or mechanistically related to, migraine, e.g., cluster headache.
本发明提供了作为调节剂的化合物,特别是作为人类KCNQ钾通道蛋白或多肽的开放剂,特别是中枢神经系统(CNS)定位的KCNQ钾通道及其异源多聚体,并且这些化合物在治疗偏头痛中的应用。本发明提供的一种新型的钾通道多肽开放剂是氟氧吲哚化合物,首次被描述为治疗偏头痛的治疗剂,通过防止神经元的异步放电。本发明提供的其他KCNQ钾通道开放剂化合物也可用于本发明的治疗方法中,包括2,4-二取代嘧啶-5-羧酰胺衍生物。根据本发明的一个或多个化合物可以单独使用,组合使用,或与其他治疗方法联合使用,以减少、改善和/或缓解偏头痛或类似于偏头痛或机制相关的疾病,例如群发性头痛。
