Résumé
Caveolin-1 (CAV-1) is related to inflammation, oxidative damage, and immunity. In order to obtain a series of dibenzoylmethane halophenols with strong anti-inflammatory and antioxidant effects targeting CAV-1, twenty-nine target compounds were therefore synthesized by Baker-Ventaraman rearrangement and demethylation reaction, starting from the substituted benzoyl chloride and o-hydroxyacetophenone, and their interactions with CAV-1 were investigated by BLI technique. Their in vitro anti-inflammatory and antioxidant properties were also evaluated. The results showed that compounds A6, A17, A18, and A29 not only specifically bind to CAV-1, but also present strong anti-inflammatory and antioxidant effects. These results suggest that this class of compounds can affect the signaling pathways related to inflammation and oxidative stress by directly acting on CAV-1. In particular, these compounds exhibit the most significantly inhibitory effects on IL-1β and COX-2 release. IL-1β plays a key regulatory role in the development of arthritis. Therefore, it is worth expecting for the application of such compounds in the prevention and treatment of arthritis.
