我们在这里提出了一个有效的替代N-甲基化的目的变形蛋白结合肽成更血清稳定和细胞渗透性的化合物。这涉及以避免困难的偶联步骤的方式将“环丙氨酸(CyAla)”掺入肽中。我们证明了这种化学方法在创建高亲和力HIV Rev蛋白结合肽的细胞可渗透衍生物中的实用性。环丙氨酸:在肽中引入N-烷基化位点可改善血清稳定性和细胞渗透性。最常见的策略,N-甲基化,需要困难,强制肽偶联反应。在这里,我们介绍了一种替代策略,涉及有效地纳入“环丙氨酸”残基的肽。该方法用于产生HIV Rev肽拮抗剂的细胞可渗透形式
We present here an efficient alternative to the N-methylation for the purpose of morphing protein-binding peptides into more serum stable and cell permeable compounds. This involves the incorporation of a ”cycloalanine (CyAla)” into a peptide in a way that avoids difficult coupling steps. We demonstrate the utility of this chemistry in creating a cell permeable derivative of a high affinity HIV Rev protein-binding peptide. Cycloalanine: Introducing sites of N-alkylation into peptides improves serum stability and cell permeability. The most common strategy, N-methylation, requires difficult, forcing peptide coupling reactions. Here we introduce an alternative strategy involving the efficient incorporation of “cycloalanine” residues into peptides. This approach is employed to create a cell permeable version of a HIV Rev peptide antagonist
