Patent

CA 2217169

Thienyl-, furyl- and pyrrolyl-sulfonamides and methods for modulating or altering the activity of the endothelin family of peptides are provided. In particular, N-(isoxazolyl)thienylsulfonamides, N-(isoxazolyl)- furylsulfonamides and N-(isoxazolyl)pyrrolylsulfonamides and methods using these sulfonamides for inhibiting the binding of an endothelin peptide to an endothelin receptor by contacting the receptor with the 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.

Thiényl-, furyl- et pyrrolyl-sulfonamides et procédés de modulation ou d'altération de l'activité de la famille endothéline des peptides. L'invention porte en particulier sur des N-(isoxazolyl)thiényl sulfonamides, N-(isoxazolyl)-furyl sulfonamides et N-(isoxazolyl)pyrrolyl sulfonamides et sur des procédés mettant en oeuvre de tels sulfonamides pour inhiber la liaison d'un peptide d'entholéline à un récepteur d'endothéline en soumettant ce récepteur au contact du sulfonamide. L'invention porte également sur des méthodes de traitement des affections à médiation par l'endothéline par administration de quantités efficaces d'un ou plusieurs de ces sulfonamides ou de promédicaments issus de ces sulfonamides inhibant ou accroissant l'activité de l'endothéline.
