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.

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.

标题:Cyclization of peptides
发明人：HUGHES JOHN L; LIU ROBERT C; SEYLER JAY K
权利人:ARMOUR PHARMA
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.
