The NRF2-KEAP1 pathway is a pivotal cellular defense mechanism against oxidative stress, regulating the transcription of cytoprotective genes. Pharmacological NRF2 activation has emerged as a promising strategy to mitigate oxidative stress-related pathologies; however, challenges regarding target specificity, pharmacodynamics, efficacy, and safety remain unresolved. Isoeugenol, a phenylpropanoid found in essential oils, has traditionally been recognized as a skin allergen but is now gaining attention for its potential as an NRF2 activator. Emerging evidence suggests that isoeugenol exerts antioxidant, anti-inflammatory, and neuroprotective effects and modulates metabolic disorders such as diabetes mellitus. Despite its therapeutic potential, the direct correlation between isoeugenol’s effects and NRF2 activation remains underexplored. Existing studies indicate that isoeugenol may activate NRF2 through multiple mechanisms, including covalent modification of KEAP1 cysteine residues, increased AKT activation and GSK3β inactivation, and glutathione depletion leading to reactive oxygen species (ROS) generation. Understanding these activation pathways is critical for leveraging isoeugenol as a therapeutic agent. This review provides a comprehensive analysis of isoeugenol’s role in modulating NRF2 activity and its implications for treating oxidative stress-driven diseases. By integrating current findings, this review highlights new insights into the therapeutic potential of isoeugenol in translational medicine. We propose future research directions to optimize its application in clinical settings, paving the way for more targeted and effective NRF2-based interventions ","cbCaid4Qw3KPWVjP","https://ap.wps.com/l/cbCaid4Qw3KPWVjP","pdf",1707573,12,"English","# Introduction\n## The KEAP1–NRF2 Pathway","[{\"question\":\"What role does the NRF2–KEAP1 pathway play in oxidative stress?\",\"answer\":\"It is a key cellular defense mechanism that regulates transcription of cytoprotective genes, helping counter oxidative-stress damage.\"},{\"question\":\"Why is NRF2 activation considered a promising therapeutic approach?\",\"answer\":\"Pharmacological activation can mitigate oxidative-stress–related pathologies, though issues such as specificity, pharmacodynamics, efficacy, and safety still need resolution.\"},{\"question\":\"How might isoeugenol activate NRF2 according to the review?\",\"answer\":\"It may activate NRF2 through covalent modification of KEAP1 cysteine residues, increased AKT activation with GSK3β inactivation, and glutathione depletion that generates ROS.\"}]","Targeting NRF2 With Isoeugenol - A Promising Small Molecule for Neurodegenerative, Metabolic, and Chronic Inflammatory Disorders | PDF",1790683981]
