7, a diazatricyclododecene 3D-scaffold 8 a, which enables the introduction of substituents into the scaffold to mimic amino acid side chains, was designed and synthesized. The peptide mimetics 21 a–u were synthesized via step-by-step installation of three substituents on diazatricyclododecene scaffold 8 a. Compounds 21 a–h were synthesized as α-helix peptide mimics of hydrophobic ZZxxZ and ZxxZZ sequences
构建了一种新型的 sp 3富碳三环 3D 支架肽模拟化合物库,以靶向蛋白质-蛋白质相互作用。三环骨架7是由 9-氮杂双环 [3,3,1]nonan-3-one ( 11)通过金 (I) 催化的 Conia-ene 反应合成的。环化前体12 b - e的悬垂炔烃上的给电子基团是形成具有完全区域选择性的6- end - dig环化产物7的关键。使用区域选择性构建桥连三环骨架7的合成策略,二氮杂三环十二烯 3D 支架8 a设计并合成了能够将取代基引入支架以模拟氨基酸侧链的方法。肽模拟物21 a – u是通过在二氮杂三环十二碳烯支架8 a上逐步安装三个取代基合成的。化合物21 a - h合成为疏水性 ZZxxZ 和 ZxxZZ 序列(Z=Leu 或 Phe)的 α-螺旋肽模拟物,并进行基于细胞的测定:抗增殖活性、HIF-1 转录活性,这被认为会影响癌症的恶性程度,和抗狂犬病病毒的抗病毒活性。化合物
