Description of the invention (& Please read the notes on the back before filling out this page) The present invention provides a method for synthesizing peptides with optical activity • Especially an alkylamine with optical activity A new method for cleavage of peptides 3-acetamidine-2-methylpropanoic acid-amino acid. Pressing, when the amine group and the carboxyl group are dehydrated to form a glycosamine with a -C0-chain structure The dehydration-condensation of an amino group on one amino acid with a carboxyl group on the other amino acid forms the form of the peptide bond. This process is called "peptide synthesis". Multiple amino acids are linked to form a peptide. The synthesis of the peptide provides a peptide with a known sequence. Therefore, it is necessary to study the relationship between structure and biological activity. It also produces a peptide with a specific sequence for X-ray crystals. Edited by Zhao, and established information on the most suitable peptides for peptides. The purpose of most peptide synthesis work is to prepare natural peptides as described above or non-natural peptides similar to natural peptides. These compounds are generally made by optical Reactive amino acids are known Degree of residues and residues of known series. Polypeptide compounds formed from racemic amino acids, because the by-products of their isomers reduce their purity and biochemical activity, and are not of practical value, so An optically active reactant is used as a raw material or the product is optically separated after the racemic synthesis is performed to prepare a compound of high purity and high physiological activity. For the synthesis of peptides, a common method for fleas is to use a coupling agent (coupling a-gent). ), Called the best amino acid coupling reaction is the carbodiide aethod (RN = C = NR,) C Sheehan, JC, Hess, GP: J. Aaer. Chen. Soc. 77, 1067 (1955 )] The reaction can be carried out in many different solvents. Dicyclohexylcarbodiinide 'is currently the most commonly used method for peptide synthesis. As for the conversion of amino acids to amino groups (& (^ -lanino acid chlorides) C Katsoyannis, PG, du Vigieaud, V: J. Aeer. Ch-en. Soc. 78, 3114 (1954)] make it more active, and then react with amine groups The α-hydrogen atom on the ether ether atmosphere is extremely acidic and therefore easily removed for inspection. Produces racemization, and easily undergoes intramolecular ring formation and turns into tritiated formazan 4 (210X297 publicly available) A6 B6 401421 5. Description of the invention ('g azlactone), which makes it useful The use of biochemically active peptides is reduced. Aminolysis of esters is another important method for preparing peptides. In order to maximize the rate of production of ribs and the highest yield, the esters containing good androsteryl are Necessary, general examples are p-Nitrophenyl ester (P ~ Nitrophenyl ester), pentachlorophenyl ester (Pentachlorophenyl ester), etc. Another commonly used method is to use enzymes with specific properties for catalysis to synthesize peptide bonds. The principle of the accelerated reaction of enzymes, like the catalyst, is to increase the number of molecules in the activated state and increase the odor by reducing the free energy of activation. This technology is already ready for the production of Aspartame double peptide | and has been industrialized. Due to the combination of peptides, the material has biological activity, and has a certain structure and optical activity. Therefore, when synthesizing peptide compounds, as described above, it is necessary to use optically active anti-substances and amino acids that are protected by the amino acid before synthesis. The peptide compounds of each residue in the sequence are known. Therefore, a large amount of human and material resources need to be invested in pre-production operations. _ _ __________________ Therefore, the present invention uses a different synthesis method to produce unnatural peptides. * To synthesize optically active alkylamino peptides, firstly, a, / 3-unsaturated atmosphere and amine group The acid is combined into α, / 3-cell and carboxyamino acid compounds, and then nucleophilic tests (such as sulfur ft acetic acid) are used for nucleophilic addition reaction, and under the action of appropriate additives, Partially stereoselection can be obtained by re-crystallizing the diastereoisomers of alkaloid peptides in varying amounts by recrystallization, and optically active alkyl-5 peptides can be obtained ( As in formula one). This method can also be extended to reference peptides, vasoactive peptides, and wood peptides.
