  摘要：

  聚焦于氧代二唑-异丙酰胺核心蛋白酶体抑制剂的合成和药物化学，提供了一种强烈抑制CT-L活性的先导化合物。结构活性关系研究表明，酰胺基团和两个苯环对合成修饰非常敏感。只有在A环上的对位取代对维持强效的CT-L抑制活性至关重要。A环对位的疏水基团和B环的间吡啶基团显著提高了抑制作用。间吡啶基团提高了细胞渗透性。A环对位的脂肪链长度是关键，丙基产生了最有效的抑制剂，而较短（即乙基，甲基或氢）或较长（即丁基，异丙基和己基）的链逐渐表现出较少的效力。在醚基团旁引入一个立体异构中心（即将一个氢原子取代为甲基）表明在蛋白酶体CT-L活性抑制中具有手性歧视（S-对映体比R-对映体更有效，效力提高了35-40倍）。
