and reported a novel vinyl sulfone (1) as an Nrf2 activator with therapeutic potential for Parkinson’s disease (PD). In this study, we changed the vinyl sulfone to vinyl sulfonamide or vinyl sulfonate to improve Nrf2 activating efficacy. We observed that the introduction of vinyl sulfonamide led to a reduction of the effects on Nrf2 activation, whereas vinyl sulfonate compounds exhibited superior activity
负责细胞抗氧化应激调节的主要途径是核因子E2相关因子2(Nrf2)信号传导。我们先前合成并报告了一种新型的乙烯基砜(1)作为Nrf2活化剂,对帕金森氏病(PD)具有治疗潜力。在这项研究中,我们将乙烯基砜更改为乙烯基磺酰胺或乙烯基磺酸盐,以提高Nrf2活化功效。我们观察到乙烯基磺酰胺的引入导致对Nrf2活化的影响降低,而磺酸乙烯基酯化合物则比乙烯基砜化合物具有更高的活性。在乙烯基磺酸盐中,3c对Nrf2活化的影响比相应的乙烯基砜(1)和乙烯基磺酰胺(3c)高6.9和83.5倍。2c)。证实化合物3c在细胞中的蛋白质水平上诱导了Nrf2依赖性抗氧化酶的表达。此外,3c通过保护MPTP诱导的PD大鼠模型中的DA能神经元,减轻了PD相关的行为缺陷。
