Thienyl-, furyl- and pyrrolyl-sulfonamides, pharmaceutically-acceptable salts of sulfonamides, formulations of salts and the sulfonamides, and methods of altering the activity of the endothelin family of peptides using the formulations and sulfonamides are provided. In particular, formulations of sodium salts of N-(isoxazolyl)thienylsulfonamides, N-(isoxazolyl)furylsulfonamides and N-(isoxazolyl)pyrrolysulfonamides are provided. A process of preparing an alkali metal salt of a hydrophobic sulfonamide is provided. The process includes the step of dissolving a free sulfonamide in an organic solvent in the presence of a saturated alkali metal salt solution and recovering the formed sulfonamide salt from the organic plant.
本发明提供了噻吩基、呋喃基和吡咯基磺酰胺类化合物、磺酰胺类化合物的药学上可接受的盐、盐和磺酰胺类化合物的制剂,以及使用这些制剂和磺酰胺类化合物改变内皮素族肽活性的方法。特别是提供了 N-(异恶唑基)噻吩基磺酰胺、N-(异恶唑基)呋喃基磺酰胺和 N-(异恶唑基)吡咯基磺酰胺的钠盐制剂。提供了一种制备疏水磺酰胺碱金属盐的工艺。该工艺包括在有饱和碱金属盐溶液存在的情况下,将游离磺酰胺溶解在有机溶剂中,并从有机植物中回收形成的磺酰胺盐。
