标题 :Synthesis of peptides and proteins
发明人：ERICKSON BRUCE W
权利人:UNIV ROCKEFELLER
摘要:Solid phase synthesis of peptides and proteins have been improved by the use of a trifunctional segment, one functional group of which is bound to a solid support, the other two functional groups being available as substrates upon which identical proteins are synthesized.

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.

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.

摘要:The synthesis of a disulfide cyclic peptide by preparing an intermediate peptide containing an amino terminal cystine residue and a cysteine residue located in a position within the amino acid sequence, to give a desired peptide, and placing such intermediate peptide in a solution substantially free of oxygen at a pH of from about 5 to 10 until rearrangement takes place to yield a cyclic disulfide peptide and to displace a molecule of cysteine from the amino terminal cysteine residue. The disclosure also embraces said intermediate peptides as new compounds and the processes by which they are prepared.
