    Abstract: A C-nitroso compound having a molecular weight ranging from about 225 to about 1,000 (from about 225 to about 600 for oral administration) on a monomeric basis wherein a nitroso group is attached to a tertiary carbon, which is obtained by nitrosylation of a carbon acid having a pKa less than about 25, is useful as an NO donor. When the compound is obtained from a carbon acid with a pKa less than about 10, it provides vascular relaxing effect when used at micromolar concentrations and this activity is potentiated by glutathione to be obtained at nanomolar concentrations. When the compound is obtained from a carbon acid with a pKa ranging from about 15 to about 20, vascular relaxing effect is obtained at nanomolar concentrations without glutathione. The compound is preferably water-soluble and preferably contains a carbon alpha to the nitrosylated carbon which is part of a ketone group.

  • Patent number: 6248767
    Abstract: Formulations of pharmaceutically-acceptable salts of thienyl-, furyl- and pyrrolyl-sulfonamides and methods for modulating or altering the activity of the endothelin family of peptides using the formulations are provided. In particular, formulations of sodium salts of N-(isoxazolyl)thienylsulfonamides, N-(isoxazolyl)furylsulfonamides and N-(isoxazolyl)pyrrolylsulfonamides and methods using these sulfonamide salts for inhibiting the binding of an endothelin peptide to an endothelin receptor by contacting the receptor with the sulfonamide salt are provided. Methods for treating endothelin-mediated disorders by administering effective amounts of one or more of these sulfonamide salts or prodrugs thereof that inhibit or increase the activity of endothelin are also provided.
