In particular, N-(4-halo-3-isoxazolyl)sulfonamides and N-(4-halo-5-isoxazolyl)benzenesulfonamides and methods for inhibiting the binding of an endothelin peptide to an endothelin receptor or increasing the activity of endothelin peptides by contacting the receptor with a sulfonamide are provided. Methods for treating endothelin-mediated disorders by administering effective amounts of one or more of these sulfonamides or prodrugs thereof that inhibit or increase the activity of endothelin are also provided.
本发明提供了N-(4-卤代
异噁唑基)磺
酰胺及其方法,用于调节或改变内皮素家族肽的活性。特别地,本发明提供了N-(4-卤代-3-
异噁唑基)磺
酰胺和N-(4-卤代-5-
异噁唑基)
苯磺
酰胺及其方法,通过接触受体与磺
酰胺来抑制内皮素肽与内皮素受体的结合或增加内皮素肽的活性。本发明还提供了通过给予这些磺
酰胺或其前药的有效剂量来治疗内皮素介导的疾病的方法,其中这些磺
酰胺或前药抑制或增加内皮素的活性。
