Novel antioxidants' synthesis and their anti-oxidative activity through activating Nrf2 signaling pathway.
Bioorganic & medicinal chemistry letters(2017)
Abstract
Novel structure compounds (WS) containing 3,4,5-trimethoxyphenyl and acyl pyrazole were designed and synthesized based combination principles. Among them, WS13 was screened out to possess desirable anti-oxidative activity in vitro. Cell survival assay and apoptosis experiment in H2O2 induced PC12 cells injury model all showed that its cytoprotection exhibited a concentration-effect manner. WS13 at 10μM could remove ROS with equal effiency to edaravone. Further, it clearly activated Nrf2 nuclear translocation and upregulated GCLC mRNA transcription and protein expression in dose-dependent manner, and its cytoprotection was reversed by GCLC protein inhibitor. In total, WS13 with further promotion can serve as Nrf2-GCLC activator in anti-oxidative therapy.
