CAS: 25024-53-7; Boc-His(Dnp)-Oh

该化合物是丁胺的一种受保护的衍生物,在Nα-位置上有一个叔丁-丁-碳基(Boc)组,在Iniidazole边链上有一个2,4-二硝基苯(Dnp)组,该化合物广泛用于peptide合成,需要选择性地保护其侧面链,以防止在结合或取消保护步骤期间出现不可取的反应.Boc组提供酸性实验室保护,而Dnp组则在标准peptide合成条件下提供稳定性,并且可以有选择地用硫醇试剂去除.其高纯度和定义明确的保护战略使它成为复杂的pited序列的可靠建筑块,特别是在固相合成和药用化学应用中.

    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:Solid phase peptide synthesis using a polyacrylic support in aqueous solution
    发明人:CALAS BERNARD; MERY JEAN; NAHARISOA HANITRA; FOLLET MICHEL
    权利人:EXPANSIA SA
    摘要:This invention relates to solid phase peptide synthesis. n Solid phase peptide synthesis is accomplished on polyacrylic resins (such as those described in EP 0 079 812 and EP 0 081 408 which correspond to U.S. Pat. Nos. 4,436,874 and 4,439,545 respectively) by a method which includes in the coupling protocol steps of washing the resin in water and/or aqueous solution(s).
