Solid phase synthesis of aryl and benzylpiperazines and their application in combinatorial chemistry

Abstract An SNAr reaction on solid phase was demonstrated in the synthesis of a piperazine library using a combinatorial approach.

Combinatorial synthesis of small-molecule libraries using 3-amino-5-hydroxybenzoic acid

SummaryA non-peptide library of 2001 compounds has been prepared utilizing solid-phase techniques. The split/combine method was demonstrated to work well to form mixtures of compounds based on 3-amino-5-hydroxybenzoic acid as a core structure. The benzoic acid of the core structure served as the attachment point for the resin and the amino and hydroxy positions were variably substituted.

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).

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).

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.

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.

Nonpeptide bradykinin antagonist analogs based on a model of a Sterling-Winthrop nonpeptide bradykinin antagonist overlapped with cyclic hexapeptide bradykinin antagonist peptides

A proposed overlap between cyclic hexapeptide Bradykinin antagonists and nonpeptide Bradykinin antagonists is discussed. Structural variations on both the peptides and nonpeptides support the proposed overlap based on an increase or decrease in the biological activities of the antagonists.

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.
