Novel inhibitors of procollagen C-proteinase. Part 2: glutamic acid hydroxamates.

Glutamic acid derived hydroxamates were identified as potent and selective inhibitors of procollagen C-proteinase, an essential enzyme for the processing of procollagens to fibrillar collagens. Such compounds have potential therapeutic application in the treatment of fibrosis.

Novel inhibitors of procollagen C-terminal proteinase. Part 1: diamino Acid hydroxamates.

The parallel synthesis of novel inhibitors of procollagen C-terminal proteinase is described. The synthetic strategy allowed for the facile synthesis of a large number of side-chain diversified diamino acid hydroxamates, of which the D-diaminopropionic acid derivatives were shown to be single digit nanomolar PCP inhibitors.

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.

Amino acid derived sulfonamide hydroxamates as inhibitors of procollagen C-proteinase: solid-phase synthesis of ornithine analogues.

A discussion of the solid-phase synthesis of ornithine derived sulfonamide hydroxamic acids is illustrated. These analogues are shown to be potent, non-peptide inhibitors of procollagen C-proteinase (PCP).

Solid-phase synthesis of di- and tripeptidic hydroxamic acids as inhibitors of procollagen C-proteinase.

A solid-phase approach to the rapid synthesis of di- and tripeptide-like hydroxamic acids is presented. These compounds are shown to be potent inhibitors of procollagen C-proteinase (PCP).
