Abstract: N-(5-isoxazolyl)benzenesulfonamides and N-(3-isoxazolyl)benzenesulfonamides 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.

Abstract: N-alkyl, N-alkenyl, N-alkynyl, N-aryl and N-fused bicyclo or tricyclo thienyl-, furyl- and pyrrolyl-sulfonamides and methods for modulating or altering the activity of the endothelin family of peptides are provided. In particular, (phenyl) and (phenoxy)thienylsulfonamides, (phenyl) and (phenoxy)furylsulfonamides, and (phenyl) and (phenoxy)pyrrolylsulfonamides and methods of 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.

Abstract: Methods, compositions, and compounds for modulating the activity of an endothelin peptide are provided. The methods use compositions that contain compounds of formula (1):
where X and Y are selected from groups that include O, S, and NH; and Ar1, Ar2 and Ar3 are independently selected from substituted or unsubstituted groups that include 5 to 6 membered aryl groups and heteroaryl groups that contain one or two heteroatom(s). The methods are effected by contacting endothelin receptors with one or more of the compounds or with compositions containing one or more of the compounds prior to, simultaneously with, or subsequent to contacting the receptors with an endothelin peptide.

Abstract: Provided herein are assays for measuring in vivo levels of activated mannan-binding protein-associated serine protease (MASP-1 and MASP-2) activity. Also provided are compounds that are useful for assessing the in vivo levels and for monitoring in vitro and in vivo complement-activation (C-activation).
