Despite resveratrol's well-documented health benefits, its mechanism of action remains controversial. In particular, the direct molecular target of resveratrol has been elusive. Park et al. now show that resveratrol directly inhibits cAMP-dependent phosphodiesterases, triggering a cascade of events that converge on the important energy-sensing metabolic regulators AMPK, SIRT1, and PGC-1α.
尽管白藜芦醇的健康益处已有充分的文献记载,但它的作用机制仍存在争议。特别是,白藜芦醇的直接分子靶标一直难以捉摸。Park 等人现在表明,白藜芦醇直接抑制 cAMP 依赖性磷酸二酯酶,引发一系列事件,这些事件集中在重要的能量感应代谢调节剂 AMPK、SIRT1 和 PGC-1α 上。
