Direct interference with Kelch-like ECH-associated protein 1 (Keap1)-Nrf2 protein-protein interaction (PPI) has recently been introduced as an attractive approach to control life-threatening diseases like myocarditis. The present study aimed to investigate the potential application in myocarditis of a series of novel non-naphthalene derivatives as potential Keap1-Nrf2 PPI inhibitors. Our results indicated that the optimal compound displayed the highest metabolic stability and showed notable Keap1-Nrf2 PPI inhibitory activities . effectively triggered Nrf2 activation and increased the protein and mRNA expression of Nrf2-regulated genes in H9c2 cells. Moreover, pre-treatment with was shown to mitigate LPS-induced damage to H9c2 cells, causing a marked decrease in the levels of inflammatory factors as well as reactive oxygen species (ROS). Furthermore, was also shown to be non-mutagenic in the Ames test. Overall, our findings suggest that may be a promising drug lead as a Keap1-Nrf2 PPI inhibitor for myocarditis treatment.

Macrophages are key players in maintaining the balance of tissues and dealing with inflammation, carrying out vital functions specific to different tissues while safeguarding the body against infections. The intricate interplay between oxidative stress and macrophage polarization and how this contributes to pneumonia is not fully understood. Herein, a predominant accumulation of baicalein in lung macrophages of pathogen-infected mice was observed by an alkynyl-modified probe.

The Keap1-Nrf2 pathway is an essential system that maintains redox homeostasis and modulates key metabolic processes, including metabolism of amino acids to promote the synthesis of antioxidant enzymes. Inhibitors of the protein-protein interaction (PPI) between Keap1 and Nrf2 have emerged as a promising strategy for developing novel classes of antioxidant agents that selectively activate this pathway without off-target effects. Carotenoids, a large family of lipophilic isoprenoids synthesized by all photosynthetic organisms, are well-known for their antioxidant activities.

In research focused on protein-protein interaction (PPI) inhibitors, the optimization process to achieve both high inhibitory activity and favorable physicochemical properties remains challenging. Our previous study reported the discovery of novel and bioavailable Keap1-Nrf2 PPI inhibitor which exhibited moderate in vivo activity in rats. In this work, we present our subsequent efforts to optimize this compound.
