- Discovery and structure-activity relationships of sulfonamide ET(A)- selective antagonists
-
Random screening of compounds in an ETA receptor binding assay led to the discovery of a class of benzenesulfonamide ligands. Optimization led to the development of 5-amino-N-(3,4-dimethyl-5-isoxazolyl)-1- naphthalenesulfonamides which were functional ant

- Process for the preparation of N-acetylaminoarylsulfonic acids in sulfuric acid as solvent
-
The invention relates to salt-free N-acetylaminoarylsulfonic acids, their preparation by acetylation with acetic anhydride or acetyl chloride, sulfuric acid, which can also contain a small amount of water and/or dimethylformamide and/or N-methylpyrrolidone, serving as the solvent, and the use of the N-acetylaminoarylsulfonic acids for the preparation of their acid chlorides.
