摘要:Disclosed are a novel method for the synthesis of a glycopeptide by which glycopeptides of various types can be deprotected and excised from a resin, each under weakly acidic to weakly basic conditions, without causing the problems of the epimerization of an amino acid at the a-position and the ß-elimination of a sugar residue; a synthesis device therefor; and a synthesis intermediate to be used in synthesizing a glycopeptide. Specifically disclosed are a method for the solid-phase synthesis of a glycopeptide which comprises a step for obtaining a glycopeptide derivative wherein the N-terminus is protected, the C-terminus is immobilized to a solid phase via a silicon linker, and a reactive group carried by a sugar residue and a reactive group carried by an amino acid side chain constituting a peptide are protected by silicon-containing groups, and a step for obtaining the glycopeptide by deprotecting said glycopeptide derivative and releasing the same from the solid phase by treating the glycopeptide derivative with an agent for removing the silicon-containing groups and the silicon linker; a synthesis intermediate to be used in the step for obtaining the glycopeptide derivative in the aforesaid method; and a device for the solid-phase synthesis of a glycopeptide.

标 题 :Flavonoid compounds capable of modifying the dynamic and/or physical state of biological membranes and to stimulate the endogenous synthesis of stress proteins in eukaryotic cells, relative synthesis and their use
发明人：PORTA AMALIA
摘要:The invention relates to flavonoids compounds of formula (I) and (II) capable of modifying the dynamic and/or physical state of biological membranes and to stimulate the endogenous synthesis of stress proteins in eukaryotic cells. Such compounds are molecules of plant origin or synthetic. The invention also describes a method to identify, purify and chemically synthesize such flavonoid compounds and test their efficacy through their capacity to stimulate the transcription of stress genes and as a consequence, to interact with biological membranes with alteration of their relative physical state. Such compounds and corresponding pharmaceutically acceptable derivatives and/or salts have applications in the areas of pharmaceuticals, more specifically in cosmetics and dermatology, for all those afections related to an alteration of the expression of stress genes.

摘要:Methods of synthesizing oligonucleotides via new intermediates on a cleavable support having an azidomethyl moiety are disclosed. The method comprises multiple reaction cycles, each of which comprises sequential coupling a nucleoside or oligonucleotide subunit on a cleavable support having an azidomethyl moiety and a nucleoside phosphoramidite or an oligonucleotide phosphoramidite, capping, oxidation/thiolation and deblocking; followed by orthogonal cleavage of the azidomethyl support while keeping all other protecting groups intact. The method can be used in combination with a support moiety for either solid phase or liquid phase oligo synthesis. The soluble support facilitates homogeneous reactions and efficient separations by simple precipitation. The methods also provide novel intermediates useful in the synthesis of oligonucleotide conjugates.

标题:Chemical amplification for the synthesis of patterned arrays

权利人:AFFYMETRIX INC
摘要:Radiation-activated catalysts (RACs), autocatalytic reactions, and protective groups are employed to achieve a highly sensitive, high resolution, radiation directed combinatorial synthesis of pattern arrays of diverse polymers. When irradiated, RACs produce catalysts that can react with enhancers, such as those involved in autocatalytic reactions. The autocatalytic reactions produce at least one product that removes protecting groups from synthesis intermediates. This invention has a wide variety of applications and is particularly useful for the solid phase combinatorial synthesis of polymers.
