of the immunoproteasome has been associated with autoimmune diseases, inflammatory diseases, and various types of cancer. Selective inhibitors of the immunoproteasome are not only scarce, but also almost entirely restricted to peptide‐based compounds. Herein, we describe nonpeptidic reversible inhibitors that selectively block the chymotrypsin‐like (β5i) subunit of the human immunoproteasome in the
免疫蛋白酶体的高表达与自身免疫性疾病,炎性疾病和各种类型的癌症有关。免疫蛋白酶体的选择性抑制剂不仅稀缺,而且几乎完全限于基于肽的化合物。本文中,我们描述了非肽类可逆抑制剂,可在低微摩尔范围内选择性阻断人免疫蛋白酶体的胰凝乳蛋白酶样(β5i)亚基。然后将最有效的可逆作用化合物转化为共价,不可逆的非肽类抑制剂,这些抑制剂保留了对β5i亚基的选择性。此外,在基于细胞的测定中,这些抑制剂可区分免疫蛋白酶体和组成型蛋白酶体。除了缺乏细胞毒性外,
