ABSTRACT:
N-(4-halo-isoxazolyl)sulfonamides and methods for modulating or altering the activity of the endothelin family of peptides are provided. 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.
