标 题 :Synthesis of hpGRF(Somatocrinin) in liquid phase and intermediate peptides
发明人：DIAZ JOSEPH; DEMARNE HENRI; RONCUCCI ROMEO; SCHMELCK PAUL-HENRY
权利人:SANOFI SA
摘要:The invention relates to synthesis of hpGRF (Somatocrinin) in liquid phase and to intermediate peptides, comprising: coupling, one after the other and in the order of the sequence of the GRF, the fragments in which: (a) the side acid functions of the aspartic and glutamic acids and the side amine function of the lysine are protected by protector groups stable in the conditions of deprotection of the group Boc, (b) the guanidine function of the arginine is protected by protonation, and (c) the N-terminal amino acid is protected on the amine by the Boc group; selectively eliminating the group Boc from the N-terminal amine of the peptide in phase of elongation by hydrolysis with trifluoroacetic acid, said coupling being effected in an aprotic polar solvent and eliminating, at the end of sequence, all the protector groups by hydrolysis with the aid of a 0.1 to 1M solution of methanesulfonic or trifluoromethanesulfonic acid in trifluoroacetic acid.

摘要:A process for the synthesis, in liquid phase and by fragments, of hGRF 1-44 and hGRF 1-40. This process consists in coupling, one after the other and in the order of the sequence of the GRF, (1) on the one hand, the following fragments: -H-Ala-Arg-Ala-Arg-Leu-NH2 called Fragment A hGRF (40-44) or - alaninamide (40) -H-Gln-Glu-Arg-Gly-OH called Fragment B'1 hGRF (36-39) -H-Glu-Ser-Asn-OH called Fragment B'2 hGRF (33-35) -H-Ser-Arg-Gln-Gln-Gly-OH called Fragment C hGRF (28-32) -H-Leu-Gln-Asp-Ile-Met-OH called Fragment D' hGRF (23-27) -H-Arg-Lys-Leu-OH called Fragment E'1 hGRF (20-22) - to obtain the peptide K1 [(hGRF (20-44)] on the corresponding peptide having the sequence (20-40) and (2) on the other hand, the following fragments: -H-Gln-Leu-Ser-Ala called Fragment F1 hGRF (16-19) -H-Tyr-Arg-Lys-Val-Leu-Gly OH called Fragment G1 hGRF (10-15) -H-Ile-Phe-Thr-Asn-Ser-OH called Fragment H1 hGRF (5-9) - to obtain the peptide J [hGRF (5-19)] and thereafter to couple together the peptides J and K1 in order to form the peptide having the sequence hGRF (5-44) or hGRF (5-40) and finally to couple the resulting peptide with the peptide H-Tyr-Ala-Asp-Ala-OH, called fragment I hGRF (1-4).

发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

标 题 :Synthesis of peptides with parathyroid hormone activity
发明人：COLESCOTT ROBERT L; TREGEAR GEOFFREY W
权利人:ARMOUR PHARMA
摘要:Resin peptides useful in the preparation of peptides having biological activity, and particularly such resin peptides containing R--CH 2 --O--Phe--Asn at one end of an amino acid chain, R being the resin and Phe and Asn being the residues of the amino acids phenylalanine and asparagine; and processes for the preparation of such resin peptides. Resin peptides are disclosed which contain amino acid chains identical with the amino acid chains of natural peptides having biological activity. Other resin peptides are disclosed which contain amino acid chains in which the amino acid residues differ in kind and sequence from amino acid chains of natural biologically active peptides but from which peptides having biological acitivity may be derived.

摘要:The synthesis of a disulfide cyclic peptide by preparing an intermediate peptide containing two cysteine moieties, each of which is protected by an n-alkylthio group, or when one of such moieties is in an amino terminal position, this one moiety may be protected by a cysteine group while the other is protected by an n-alkylthio group, and placing such intermediate peptide in a solution substantially free of oxygen and preferably at a pH of from 5 to 10 until rearrangement has taken place, to yield a cyclic disulfide peptide. The disclosure also embraces said intermediate peptides as new compounds and the processes by which they are prepared.
