cancers, competes with Nrf2 for Keap1 binding, leading to activation of Nrf2-mediated gene expression and survival of cancer cells. We had previously identified an inhibitor for the Keap1-phosphorylated-p62 (p-p62) protein-protein interaction (PPI), the acetonyl naphthalene derivative K67. In this study, we established facile synthetic routes for K67 and derivatives with various side chains on the C-2
Keap1-Nrf2系统不仅参与生物防御,而且还参与恶性进展和化学抗药性。在多种癌症中高度表达的泛素结合蛋白p62 / Sqstm1(p62)与Nrf2竞争Keap1结合,从而激活Nrf2介导的基因表达和癌细胞的存活。我们先前已经确定了Keap1-磷酸化p62(p-p62)蛋白质-蛋白质相互作用(PPI)的抑制剂,即丙酮基萘衍生物K67。在这项研究中,我们为萘环的C-2位置上的各种侧链的K67及其衍生物建立了简便的合成路线。K67在抑制Keap1-p-p62方面具有很高的选择性。其他衍生物显示出有效的Keap1-Nrf2和Keap1-p-p62 PPI抑制活性,
