Amino acid derived sulfonamide hydroxamates as inhibitors of procollagen C-proteinase. Part 2: Solid-phase optimization of side chains

Optimization of the amino acid side chain and the N-alkyl group of the sulfonamide of amino acid derived sulfonamide hydroxamates is discussed. The solid-phase synthesis of these potent inhibitors of procollagen C-proteinase (PCP) is presented. In addition, novel carboxylic acid sulfonamides were discovered to be PCP inhibitors.
