The proteasome is a multicatalytic proteinase complex which plays a central role in intracellular protein degradation. We report here the synthesis and biological activities of a new class of specific proteasome inhibitors selective for trypsin-like activity. These tripeptide-based compounds bearing a C-terminal vinyl ester are nontoxic, and do not affect cell proliferation, but are able to modulate
蛋白酶体是一种多催化蛋白酶复合物,在细胞内蛋白降解中起着核心作用。我们在这里报告对胰蛋白酶样活性有选择性的一类新的特定蛋白酶体抑制剂的合成和生物学活性。这些带有C末端乙烯基酯的基于三肽的化合物是无毒的,不会影响细胞增殖,但是能够调节由MHC I类分子呈递的免疫原性肽的生成和呈递。
