  Focused library synthesis and medicinal chemistry on an oxadiazole-isopropylamide core proteasome inhibitor provided the lead compound that strongly inhibits CT-L activity. Structure activity relationship studies indicate the amide moiety and two phenyl rings are sensitive toward synthetic modifications. Only para-substitution in the A-ring was important to maintain potent CT-L inhibitory activity. Hydrophobic residues in the A-ring's para-position and meta-pyridyl group at the B-ring significantly improved inhibition. The meta-pyridyl moiety improved cell permeability. The length of the aliphatic chain at the para position of the A-ring is critical with propyl yielding the most potent inhibitor, whereas shorter (i.e. ethyl, methyl or hydrogen) or longer (i.e. butyl, propyl and hexyl) chains demonstrating progressively less potency. Introduction of a stereogenic center next to the ether moiety (i.e. substitution of one of the hydrogens by methyl) demonstrated chiral discrimination in proteasome CT-L activity inhibition (the S-enantiomer was 35-40 fold more potent than the R-enantiomer).

  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）。
