The N-capping box is a distinct helix-stabilizing motif frequently found in proteins. In this study, we examined a ruthenium-mediated intramolecular backbone to side chain macrocyclization as a rigidified mimicry of the N-capping box. Experimental data indicate that the 15-membered macrocycle formed by a hept-4-enoyl staple, which directly tethers the α-amino group of N1 residue and the α-carbon of N3 residue, is highly effective in stabilizing helical structures of short peptides.

N上限框是蛋白质中常见的独特的螺旋稳定基序。在这项研究中，我们研究了钌介导的分子内骨架到侧链的大环化，作为N帽盒的刚性模拟。实验数据表明，直接将N1残基的α-氨基和N3残基的α-碳拴在一起的庚4-烯丙基短钉形成的15元大环在稳定短肽的螺旋结构方面非常有效。
