转录因子核因子类红细胞2相关因子2(Nrf2)及其负调节剂E3连接酶衔接子Kelch样ECH相关蛋白1(Keap1)控制氧化还原和代谢体内稳态以及氧化应激。Keap1-Nrf2相互作用的抑制剂在氧化应激相关的炎性疾病中很有前途,但现在遇到了障碍。通过利用噻唑烷酮部分来屏蔽Keap1-Nrf2抑制剂中的关键羧基药效团,开发了一种过氧化氢(H 2 O 2)响应型前药pro2。前药修饰改善了母体药物的理化性质和细胞膜通透性。Pro2稳定并在各种生理条件下保持惰性,而通过刺激H 2 O 2或炎症衍生的活性氧而变得活跃。而且,pro2显示出适合口服给药的适当的药代动力学特征,并增强了体内的抗炎效率。因此,这种新颖的前药方法不仅可以为治疗高水平H 2 O 2的慢性炎性疾病提供重要的进展,而且可以为改善Keap1-Nrf2抑制剂的类药物和选择性问题提供新的解决方案。

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.

The present application relates to a hydrogen peroxide-responsive Keap1-Nrf2 PPI inhibitor prodrug, and a preparation method therefor. The hydrogen peroxide-responsive Keap1-Nrf2 PPI inhibitor prodrug pro2 has a chemical structure as shown below. By modifying a key carboxyl pharmacophore in a Keap1-Nrf2 inhibitor with a H
