|Aging Phenotype||Shortened life-span|
|Description||PBN failed to extend the life-span of houseflies and was toxic at higher doses (Dubey et al., 1995).|
|Gene Function||Nitrones are free radical traps, but it has been suggested that the neuroprotective and anti-aging activities of nitrones do not result from mass action free radical quelling activity (Floyd et al. 2002).|
|Other Phenotypes||PBN causes a decrease in protein carbonyl content in the gerbil brain cortex (Dubey et al., 1995).|
PBN has been reported to extend life-span in mice and to extend the replicative life-span of human cells in vitro.
