Caloric restriction extends life span and helps ward off diseases of aging in model organisms and may do so in primates as well. It's not pleasant, though, so a way to mimic its effect with a drug would be more appealing. Lucanic et al. screened for such a compound in the worm Caenorhabditis elegans and found one that extended life span in a manner similar to dietary restriction. Experiments to trace the point of action of the compound indicated that it may act by limiting activity in a neuronal pathway that senses the presence of food. Thus, sensory signaling pathways might be targets for agents that could mimic beneficial effects of dietary restriction on aging and health span.
