10), ChT-L activity alone was significantly inhibited. In silico docking performed on the β5 and β1 subunits bearing the respective ChT-L and PA catalytic sites showed features common to poses associated with active compounds. These features may constitute a selectivity criterion for structure-guided inhibitor design.
合成了一系列新的含噻吩的苯氧基丙醇胺,并评估了它们抑制哺乳动物20S蛋白酶体的三种蛋白水解活性的能力。ChT-L和PA活性均受到三种化合物的显着抑制:一种具有未取代的苯氧基丙醇胺基团(7),另外两种具有对-Cl-取代基团(4和9)。对于其它三种化合物(3,8和10),CHT-L活性单独显著抑制。在计算机上对带有各自ChT-L和PA催化位点的β5和β1亚基进行的对接显示出与活性化合物相关的姿势共有的特征。这些特征可以构成用于结构指导的抑制剂设计的选择性标准。
