The present invention relates to a supported oxidation reactant of formula (I): R-[Met(O)k]n-X- (I) in which: - R represents a hydrogen atom or an amine function-protecting group, -[Met(O)] represents an oxidized methionine residue of formula - k is 1 or 2 - represents a solid or soluble support used in organic synthesis, - X represents a radical derived from a function of the type amine or hydroxyl, or halogeno, capable of anchoring methionine, it being understood that this function capable of anchoring methionine can be separated from the support by means of a functionalized arm or a spacer, and - n is an integer greater than or equal to 1. The invention also relates to the use of a supported oxidation reactant of formula (I), for the formation of intramolecular disulfide bridges, in particular in peptides and/or proteins.
摘要:
The invention relates to a dipeptide conjugate having general formula I, AA2-AA1-NH2, wherein A represents the radical corresponding to a monocarboxylic acid with general formula II, HOOC-R, in which: R represents a linear or branched aliphatic radical at C1-C24, which is optionally substituted by a hydroxyl group and which can comprise one or more unsaturations, preferably between 1 and 6 unsaturations, and/or which can comprise a phenyl group or lipoic acid or the reduced form thereof, dihydrolipoic acid or N-lipoyllysine; and AA1 and AA2 represent identical or different amino acids which are selected from the group containing Ala, Asn, Cys, Gln, Gly, Ile, Leu, Met, Phe, Pro, Ser, Thr, Trp, Tyr, Val, Asp, Glu, Arg, His, Lys, Orn, Dap, Dab, the corresponding homo-amino acids and the corresponding beta-amino acids in the form of enantiomers or diastereoisomers and mixtures thereof, including racemic mixtures.
摘要:
The present invention relates to new biopolymer, i.e. bioorganic nylons incorporating peptidic blocks obtained by a process of polymerization of amino peptidic blocks. The process of the invention comprises the steps of mixingamino peptidic blocks with or without a diaminoalcane and reacting the mixture according to polycondensation with a diacyl chloride in homogeneous or heterogeneous media.
