    • This invention relates generally to medical treatment methods. Specifically, the invention relates to methodology for the correction of defective chloride transport by activation of chloride channels of the lung and other epithelia using genetic or chemical modification. These methods relate to the treatment of epithelia with compounds which cause activation of the channel as measured by increased probability (Po) of opening of the channel at physiologically relevant holding potentials. These methods also relate to the treatment of epithelia with gene therapy to introduce chloride channels genes with site mutations which cause activation of the channel as measured by increased probability (Po) of opening of the channel at physiologically relevant holding potentials. These treatments will reduce life-threatening complications frequently found in diseases such as cystic fibrosis. These methods of activation of chloride channels also comprise treatment of chloride channels with amidation reactions.
    • 本发明一般涉及医疗方法。 具体地,本发明涉及通过使用遗传或化学修饰激活肺和其他上皮的氯化物通道来校正有缺陷的氯转运的方法。 这些方法涉及用生理相关保持电位增加通道开放概率(Po)测量的引起通道活化的化合物来治疗上皮细胞。 这些方法还涉及通过基因治疗来治疗上皮细胞以将氯化物通道基因引入位点突变,所述位点引起通道的激活,其通过在生理相关的保持电位下通道开放的概率(Po)来测量。 这些治疗可以减少在诸如囊性纤维化等疾病中经常发现的危及生命的并发症。 这些氯化物通道的活化方法还包括用酰胺化反应处理氯化物通道。

    • This invention provides a method for increasing the permeability of epithelial cells to a chloride ion in a subject comprising administering a permeability enhancing amount of a composition comprising a specifically-defined nontoxic, benzimidazole or benzimidazole derivative. The invention also relates to a method of treating cystic fibrosis comprising administering an epithelial cell chloride permeability enhancing amount of a composition comprising a specifically-defined nontoxic, benzimidazole or benzimidazole derivative. The benzimidazole compound having chloride channel activation activity for use in this invention includes a 2-[(pyridyl)-methylsulfinyl or -methylthio]benzimidazole derivatives and salts thereof, for instance. Specifically, these include the compounds omeprazole, lansoprazole, thimoprazole and pantoprazole. When appropriately applied, these compounds can correct detective chloride transport, increasing the salt and water flux in diseased tissues to levels closer to those of normal tissues thus reducing life-threatening complications.
    • 本发明提供了增加受试者中上皮细胞对氯离子的渗透性的方法,包括给予渗透性提高量的包含特异性无毒的苯并咪唑或苯并咪唑衍生物的组合物。 本发明还涉及一种治疗囊性纤维化的方法,包括施用上皮细胞氯化物渗透性增加量的包含特异性定义的无毒苯并咪唑或苯并咪唑衍生物的组合物。 具有用于本发明的氯化物通道活化活性的苯并咪唑化合物包括例如2 - [(吡啶基) - 甲基亚磺酰基或 - 甲硫基]苯并咪唑衍生物及其盐。 具体地,这些包括化合物奥美拉唑,兰索拉唑,噻喹酮和泮托拉唑。 当适当应用时,这些化合物可以纠正检测氯转运,将病变组织中的盐和水通量增加到更接近于正常组织的水平,从而减少危及生命的并发症。
