  磷酸化 p62 和 Keap1 之间蛋白质-蛋白质相互作用的抑制剂减弱人肝细胞癌细胞系的化学抗性

  摘要：

  摘要 对抗癌药物的耐药性一直是开发治疗方法和降低医疗成本的障碍。虽然索拉非尼用于治疗人类肝细胞癌 (HCC)，但耐药性限制了其疗效。p62 是一种多功能蛋白，在几种 HCC 细胞系（例如 Huh-1 细胞）中过表达。磷酸化的 p62 ( p -p62) 抑制 Keap1 和 Nrf2 之间的蛋白质-蛋白质相互作用 (PPI)，导致 Nrf2 过度激活，从而导致耐药性。我们发现了一种独特的 Nrf2 灭活剂，名为 K67，它抑制了 Keap1 和p之间的 PPI-p62 并减弱 Huh-1 细胞中的索拉非尼耐药性。在此，我们通过修饰 K67 的两个苯磺酰基的 4 位取代基，设计并合成了新型 K67 衍生物。尽管这些新衍生物抑制 Keap1- p- p62 PPI 的水平与 K67 相当或更弱，但异丙氧基衍生物比 K67 更大程度地增强了 Huh-1 细胞对索拉非尼的敏感性，而对细胞活力没有任何影响。

  Activation of the transcription factor Nrf2 has been posited to be a promising therapeutic strategy in a number of inflammatory and oxidative stress diseases due to its regulation of detoxifying enzymes. In this work, we have developed a comprehensive structure activity relationship around a known, naphthalene-based non-electrophilic activator of Nrf2, and we report highly potent non-electrophilic activators of Nrf2. Computational docking analysis of a subset of the compound series demonstrates the importance of water molecule displacement for affinity, and the X-ray structure of di-amide 12e supports the computational analysis. One of the best compounds, acid 16b, has an IC50 of 61 nM in a fluorescence anisotropy assay and a K-d of 120 nM in a surface plasmon resonance assay. Additionally, we demonstrate that the ethyl ester of 16b is an efficacious inducer of Nrf2 target genes, exhibiting ex vivo efficacy similar to the well-known electrophilic activator, sulforaphane.

  Directly disrupting the Keap1-Nrf2 protein protein interaction (PPI) is an effective way to activate Nrf2. Using the potent Keap1-Nrf2 PPI inhibitor that was reported by our group, we conducted a preliminary investigation of the structure activity and structure property relationships of the ring systems to improve the drug-like properties. Compound 18e, which bore p-acetamido substituents on the side chain phenyl rings, was the best choice for balancing PPI inhibition activity, physicochemical properties, and cellular Nrf2 activity. Cell-based experiments with 18e showed that the Keap1-Nrf2 PPI inhibitor can activate Nrf2 and induce the expression of Nrf2 downstream proteins in an Nrf2-dependent manner. An exploratory in vivo experiment was carried out to further evaluate the anti-inflammatory effects of 18e in a LPS-challenged mouse model. The primary results indicated that 18e could reduce the level of circulating pro-inflammatory cytokines induced by LPS and relieve the inflammatory response.
