CAS: 55260-24-7; Boc-Gln(Xan)-Oh

该化合物是一种受保护的谷类衍生物,由N终点端的Boc(乙氧碳基)组和保护侧链状氨基的xanthyl(Xan)组组成,该化合物被广泛用于peptide合成,以防止在联动步骤中出现意外的侧反应.Boc组在基本条件下保持稳定,可以在酸性条件下有选择地去除,Xan组为谷类胺侧链提供正方保护,确保复杂的化聚体具有高度选择性.其强大的保护组和符合标准固相聚聚聚苯乙烯合成(SPPS)议定书的兼容性使得研究人员可以可靠地选择如何精确地纳入谷类胺残留物.

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.
