Nurturing longevity through natural compounds: Where do we stand, and where do we go?

Abstract

Abstract The revolution in aging research through the past decade has driven the progress in interventions that promote longevity. Dissection of the “old” hallmarks of aging has provided solid data for the definition of at least three “new” ones, opening avenues for the development of novel hallmark‐targeted pro‐longevity approaches. The quest for geroprotectors is of enormous interest with the ultimate goal of finding the alchemical stone that induces healthy aging and increases lifespan, pushing the limits of human longevity or even uncovering the absence of such limits. Several of the well‐appreciated geroprotectors that are recognized as longevity promoters are of natural origin such as metformin, resveratrol, aspirin, and spermidine. As the search for pharmacological modulators of healthspan and lifespan continues, numerous studies are focusing on the potential of plant secondary metabolites. The current review attempts to critically assess the available interventions and the breakthrough discoveries in the field of longevity research over the past decade. Correspondingly, novel approaches targeting the hallmarks of aging have been outlined, and the future goals in longevity research have been enlightened. Special emphasis has been placed on the potential of plant‐derived compounds as pro‐longevity agents.
