摘要:An apparatus for use in chemical synthesis, especially peptide synthesis, comprises a synthesis chamber unit having a multiplicity of synthesis chambers, each of which has a liquid inlet and a liquid outlet, means for introducing liquid into the individual synthesis chambers and means for simultaneous removal of liquid via the liquid outlets of the synthesis chambers by regulation of the fluid pressure difference between the liquid inlets and the liquid outlets. A method for peptide synthesis using such an apparatus comprises the provision in each of the synthesis chambers of a solid-phase support material having a first, at least N-protected amino acid coupled thereto, after which a liquid deprotection reagent is introduced into the synthesis chambers. Following deprotection, the deprotection reagent is removed, after which a second, at least N-protected amino acid is introduced into each synthesis chamber in order to couple the first and second amino acids. Third, fourth, etc. amino acids may be coupled analogously. Complete removal of the deprotection reagent from the synthesis chambers and the support material can be ensured by incorporating a stable, intensely coloured dye, e.g., azorubin, in the deprotection reagent. The apparatus and the method make possible the parallel synthesis of a large number of peptides, e.g. peptides having overlapping amino acid sequences and constituting part of a longer peptide chain. The apparatus can be adapted to manual, semi-automatic or fully automatic performance of the various steps in the synthesis procedure.

摘要:A method of solid-state synthesis of peptides that provides a polymeric solid-state synthesis support, attaches a first amino acid to said support to form the first amino acid molecule of the desired peptide chain, attaches additional amino acids to form the desired peptide chain, characterized in that the polymeric solid-state synthesis support is a styrenic polymer containing at least 50 mol % divinylbenzene monomer units, the styrenic polymer being functionalized with chloromethyl and/or benzyloxybenzyl alcohol and/or amino moieties, and having porosity 60-90% and medium pore diameter ranging from 10 to 80 nm. A functionalized styrenic polymer is claimed.

标题 :Synthesis of cyclic peptides

摘要:This invention relates to methods for preparing cyclic peptides and peptidomimetic compounds in solution and bound to solid supports, and to cyclic peptide or peptidomimetic libraries for use in drug screening programs. In particular, the invention relates to a generic strategy for synthesis of cyclic peptides or peptidomimetics that enables the efficient synthesis under mild conditions of a wide variety of desired compounds. Two approaches were evaluated for their improvements in solution and solid phase synthesis of small cyclic peptides: positioning reversible N-amide substituents in the sequence; and applying native ligation chemistry in an intramolecular sense. Systematic investigation of the effects of preorganising peptides prior to cyclisation by using peptide cyclisation auxiliaries, and developing new linkers and peptide cyclisation auxiliaries to aid cyclic peptide synthesis gives surprising improvements in both yields and purity of products compared to the prior art methods. The combination of these technologies provides a powerful generic approach for the solution and solid phase synthesis of small cyclic peptides. The ring contraction and N-amide substitution technology of the invention provide improved methods for the synthesis of cyclic peptides and peptidomimetics. When used in conjunction with linker strategies, this combination provides solid-phase avenues to cyclic peptides and peptidomimetics.

标题 :Synthesis of N-substituted oligomers

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.
