A large set of N5-derivatives of cerpegin (1,1,5-trimethyl furo[3,4-c]pyridine-3,4-dione) was designed and synthesized in high yields by a simple and handy method using various primary amines for a pyridine cycle synthesis. The effects of 29 derivatives on the three types of catalytic sites of purified mammalian 20S proteasomes (CT-L, T-L and PA) were measured. Most of the new compounds specifically
通过简单方便的方法,使用各种主要化合物,设计并合成了一大批cerpegin的N 5衍生物(1,1,5-三甲基呋喃[3,4-c]吡啶-3,4-二酮)胺用于吡啶循环合成。测量了29种衍生物对纯化的哺乳动物20S蛋白酶体的三种催化位点(CT-L,TL和PA)的影响。大多数新化合物都在微摩尔范围内特异性抑制PA活性。对接实验支持这些结果。此外,钙蛋白酶I和组织蛋白酶B均未受到抑制。
