BioAssay: AID 762111

Induction of Nrf2/Keap1 in human HCT116 cells assessed as induction of ARE activity after 12 hrs by luciferase reporter gene assay

When exposed to electrophiles, human colorectal cancer cells (HCT116) counteract oxidative stress through activating NF-E2-related factor 2 (Nrf2)/antioxidant response element (ARE) pathway. To identify new activators, luciferase reporter gene assay was used to screen in-house database of our laboratory, leading to a novel alpha-pyrone compound 1 as a hit. 2 with 2-fluoro phenyl group exhibited more ..

Description:
Title: Synthesis and bioevaluation of a series of alpha-pyrone derivatives as potent activators of Nrf2/ARE pathway (part I).

Abstract: When exposed to electrophiles, human colorectal cancer cells (HCT116) counteract oxidative stress through activating NF-E2-related factor 2 (Nrf2)/antioxidant response element (ARE) pathway. To identify new activators, luciferase reporter gene assay was used to screen in-house database of our laboratory, leading to a novel alpha-pyrone compound 1 as a hit. 2 with 2-fluoro phenyl group exhibited the strongest ARE inductive activity in the first round structure-activity relationship (SAR) study. Biological studies showed the compound induced nuclear translocation of Nrf2 preceded by phosphorylation of ERK1/2. The data encouraged us to use 2 as lead and 20 derivatives were synthesized to discuss a more detailed SAR, leading to a more potent compound 9, which can be the starting compound for further modification.
