标题 :Methods for the synthesis of α- hydroxy-β-amino acid and amide derivatives

摘要:Methods for the synthesis of alpha-hydroxy-beta-amino acid and amide derivatives and alpha-ketoamide derivatives and novel derivatives made by these methods are provided. These methods involve reacting a N-terminally blocked (protected) aminoaldehyde with an isonitrile and a carboxylic acid to give an amino-alpha-acyloxy carboxamide. The acyloxy group may be removed to give the derivative. Alternatively the protecting group is removed and acyl shift occurs to give the derivative. These derivatives are useful in the synthesis of compounds such as peptidyl alpha-ketoamides and alpha-hydroxy-beta-carboxylic acid and amide derivatives. Certain of these compounds have been reported to have activity as inhibitors of proteases, such as serine proteases and cysteine proteases.

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).

标 题:Combinatorial organic synthesis of unique biologically active compounds
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.
