摘要:Methods for the synthesis of cyclic peptides are provided, as well as novel dipeptide compounds. The methods include the solid phase synthesis of a dipeptide, which is the coupled to a second peptide in a solid phase reaction. The peptide is then cyclized following the coupling reaction. The methods and dipeptides are particularly useful for the synthesis of MC-4 receptor agonist peptides.

摘要:Provided is a method for fully liquid-phase synthesis of a GRnH nonapeptide amide analog, which belongs to the technical field of medicine synthesis. The method comprises respectively synthesizing a 'Trp-Ser-Tyr' fragment, an 'R-Leu' fragment, a 'Pyr-His' fragment and 'Arg-Pro-Hunan T', wherein, R = D-Ala (alarelin), D-Leu (leuprorelin), D-Trp (deslorelin) and D-His (histrelin), and obtaining the GRnH nonapeptide amide analog with high yield and high purity by means of a '3 +2 +2 +2' fragment condensation method. The synthesis method is environmentally friendly, mild, and free of any highly toxic and poisonable reagents. The cost is greatly reduced and the synthesis method is very suitable for large-scale production.

摘要:The present invention relates to an improved process for the synthesis of glucagon-like-peptide-1 (GLP-1) and its analogs by using combination of solid and solution phase synthesis of Fmoc protected amino acids in a sequential manner, optionally incorporating Boc protected dipeptide for unnatural amino acid in the Sequence of GLP-1, cleaving GLP-1 sequence from the resin followed by purification; attaching side-chain to the desired amino acid in the solution phase to synthesize desired GLP-1 analog, purifying it to Semaglutide. Temperature gradient is applied during initial coupling of amino acids to facilitate completion of difficult coupling reactions.

摘要:The present invention relates to the field of total chemical synthesis of ubiquitin and related peptides. More in particular, a method is provided of solid phase synthesis of ubiquitin, ubiquitin mutants and derivatives thereof. It was the object of the present invention to provide an approach for the total chemical synthesis of ubuiqitin, which allows for the chemical synthesis of virtually any Ub mutant and giving high overall efficiency and purity. The present inventors have surprisingly found that this object can be realized with a method relying on incorporation of special amino acid building blocks. This approach was found to allow for exceptionally high yields of up to 14% and to provide an synthetic entry into virtually any ubiquitin derivative.

权利人:CENTRE NAT RECH SCIENT
摘要:The invention relates to nonpeptide oligomers of amino acids. The oligomers comprise -(NR'-A-CO)-O- units which represent a nonpeptide, restricted-mimetic inducer of the beta turn in a dipeptide or tripeptide fragment. Said oligomers may be produced by peptide synthesis techniques, whether in solution or in the solid phase, and can be used in the synthesis of synthetic proteins or polypeptides, in which the peptide fragment(s) (is) are identical to those of the corresponding natural protein or polypeptide and whose structural fragment(s) comprise(s) a fragment of an oligomer according to the invention.

摘要:The present invention relates to the efficient solid-phase synthesis of Icatibant represented by Formula (I). The present invention relates to an efficient process for the preparation of Icatibant by sequential coupling employing solid phase approach. It involves sequential coupling of protected amino acids to prepare Icatibant. The present invention also involves the usage of inorganic salts during the coupling, wash with HOBt in DMF solution after Fmoc-deprotection step to ensure complete removal of piperidine and reactions are going for completion, and thus avoid addition/deletion sequences and also improve the process yield.
