interface leading to inactive enzyme, conformationally constrained "molecular tongs" have been designed and synthesized to interfere with one monomer end in a beta-sheet fashion. These molecules are based on two peptidic strands attached to an aromatic scaffold. Inhibitions (submicromolar range) were obtained with molecular tongs containing tripeptidic or tetrapeptidic arms attached to a pyridinediol- or
人类免疫缺陷病毒1型蛋白酶(HIV-1 PR)的活性形式是同型二聚体结构,其中两个亚基通过由每个单体的N和C末端组成的双链反平行β-折叠连接。为了抑制二聚化过程或破坏导致不活跃酶的二聚体界面,已经设计并合成了构象约束的“分子钳”以β-折叠的方式干扰一个单体末端。这些分子基于与芳香族支架相连的两条肽链。用含有三肽或四肽臂的分子钳获得抑制(亚微摩尔范围),所述三肽臂或四肽臂连接到基于吡啶二醇或萘二醇的支架上(Kid = 0.56-4.5 microM,在pH 4.7和30摄氏度下)。
