) model. The results revealed that all the caffeoylquinic acids significantly extended the lifespan of wild-type worms, of which 3,5-diCQA was the most potent compound. Meanwhile, 3,5-diCQA enhanced the healthspan by increasing the body bending and pharyngeal pumping rates and reducing the intestinal lipofuscin level. Further studies demonstrated that 3,5-diCQA induced longevity effects by downregulating the insulin/insulin-like growth factor signaling (IIS) pathway. This study suggested that the combination of molecular docking and genetic analysis of specific worm mutants could be a promising strategy to reveal the anti-aging mechanisms of small molecule natural compounds.
