modulation of the proteasome activity by specific inhibitors may represent a useful tool for the treatment of tumours. Here, we report synthesis and activity of a new series of oligopseudopeptide analogues bearing a vinyl ketone pharmacophoric unit at the C-terminal position. Some derivatives showed inhibition in the µM range of the trypsin-like (T-L) active site of the proteasome.
负责许多细胞蛋白更新的泛素-蛋白酶体途径代表了新药疗法发展中的诱人目标:特别是,特定抑制剂对蛋白酶体活性的调节可能代表了治疗肿瘤的有用工具。在这里,我们报道了一系列新的寡聚肽类似物的合成和活性,这些类似物在C端位置带有乙烯基酮药效团。一些衍生物在蛋白酶体的胰蛋白酶样(TL)活性位点的µM范围内显示出抑制作用。
