专利号:US-5977301-A 优先权日:1992-09-24 标题 :Synthesis of N-substituted oligomers 发明人:ZUCKERMAN RONALD N; KERR JANICE M; KENT STEPHEN B H; MOOS WALTER H; SIMON REYNA J; GOFF DANE A 权利人:CHIRON CORP 摘要:A solid-phase method for the synthesis of N-substituted oligomers, such as poly (N-substituted glycines) (referred to herein as poly NSGs) is used to obtain oligomers, such as poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two 'sub-monomers' directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by -NH2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a resin-bound alpha -haloacetamide) with a sufficient amount of a second sub-monomer comprising an -NH2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like. Repetition of the two step cycle of acylation and displacement gives the desired oligomers. The efficient synthesis of a wide variety of oligomeric NSGs using automated synthesis technology of the present method makes these oligomers attractive candidates for the generation and rapid screening of diverse peptidomimetic libraries. The oligomers of the invention, such as N-substituted glycines (i.e. poly NSGs) disclosed here provide a new class of peptide-like compounds not found in nature, but which are synthetically accessible and have been shown to possess significant biological activity and proteolytic stability.

专利号:US-6310180-B1 优先权日:1993-06-21 标 题 :Method for synthesis of proteins 发明人:TAM JAMES P 权利人:UNIV VANDERBILT 摘要:A method for peptide synthesis is disclosed that requires neither protecting groups nor activation of the C-α carboxyl groups. The method comprises ligating a first molecule to a second molecule by promoting the orthogonal coupling of the molecules to each other. In an aspect of this method, an acyl-type reaction occurs between the molecules. The method contemplates the joining of molecules of variant size to each other, as well as the coupling of multiple identical molecules. The invention also covers the ligation of unprotected peptide, proteins or nonpeptide segments to prepare therapeutic products and synthetic vaccines with linear, circularized, or branched backbone structures, as well as the site-specific modification of peptides or proteins by lipidation and pegylation.
专利号:EP-0498801-B1 优先权日:1989-09-15 标题:Solid surface for peptide synthesis 发明人:GEYSEN HENDRIK MARIO 权利人:CHIRON MIMOTOPES PTY LTD 摘要:There is disclosed a solid surface, such as the surface of a rod or pin, for use in the synthesis of polymeric compounds such as peptides. The surface comprises an active region and an inactive region being positioned such that, in use, it is below the surface of the reaction liquid in a reaction well, irrespective of minor variations in liquid levels between various wells so as to eliminate the formation of deletion compounds. There are further described such surfaces for the formation of relatively large quantities of compound wherein the active region has a higher surface area/volume ratio than that of a cylinder of corresponding volume.
