Pyrrole-imidazole polyamide ligands are highly sequence specific synthetic DNA-binding ligands that bind with high affinity. To counter the synthetic difficulties associated with coupling the electron-rich heterocyclic acids to the electron-deficient nucleophilic imidazole amine, a novel approach is described for synthesis of Fmoc-protected dimers for solid-phase peptide synthesis (SPPS). This method produces
吡咯-咪唑聚酰胺配体是具有高亲和力的高度序列特异性合成DNA结合配体。为了解决与将富电子杂环酸偶联至缺电子亲核咪唑胺相关的合成难题,描述了一种用于固相肽合成(SPPS)的Fmoc保护的二聚体合成新方法。该方法以高收率生产二聚体,广泛适用于其他含杂环的聚酰胺,并提高了配体收率和合成时间。
