generation of inhibitors targeting specific subunits within the immunoproteasome is of interest for the treatment of autoimmune disease. There are three catalytic subunits within the immunoproteasome (low molecular mass polypeptide-7, -2, and multicatalytic endopeptidase complex subunit-1; LMP7, LMP2, and MECL-1), and a campaign was undertaken to design a potent and selective LMP2 inhibitor with sufficient
基于硼替佐米(VELCADE)和卡非佐米(KYPROLIS)的成功,设计针对免疫蛋白酶体中特定亚基的下一代抑制剂对于治疗自身免疫性疾病非常重要。免疫蛋白酶体内有三个催化亚基(低分子量多肽7,-2和多催化内肽酶复合物亚基1; LMP7,LMP2和MECL-1),并开展了一场活动来设计一种有效且选择性的LMP2抑制剂具有足以在体内持续抑制的特性。筛选了聚焦的环氧酮文库,发现了一系列有效的二肽,这些二肽经过优化可提供高选择性抑制剂KZR-504(12)。
