N-(5-isoxazolyl)benzenesulfonamides and N-(3-isoxazolyl) benzene-sulfonamides and methods for modulating or altering the activity of the endothelin family of peptides are provided. In particular, N-(5-isoxazolyl)-biphenylsulfonamides and N-(3-isoxazolyl)biphenylsulfonamides 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. N-isoxzolyl-4-biphenylsulfonamides are particularly preferred. These compounds exhibit activity as endothelin receptor B antagonists. Methods for treating endothelin-mediated disorders, particularly inflammatory diseases, such as asthma, 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.
提供了N-(5-异噁唑基)苯磺酰胺和N-(3-异噁唑基)苯磺酰胺及其方法,用于调节或改变内皮素家族肽的活性。特别提供了N-(5-异噁唑基)-联苯磺酰胺和N-(3-异噁唑基)联苯磺酰胺及其方法,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。N-异噁唑基-4-联苯磺酰胺特别受欢迎。这些化合物表现出内皮素受体B拮抗剂的活性。还提供了通过给予这些磺酰胺或其前药中的一种或多种有效量来抑制或增加内皮素活性,特别是治疗内皮素介导的疾病,如哮喘的方法。
