Alternate NamePBN
OrganismMusca domestica
Aging PhenotypeShortened life-span
Allele TypeN/A
DescriptionPBN failed to extend the life-span of houseflies and was toxic at higher doses (Dubey et al., 1995).
Gene FunctionNitrones 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 PhenotypesPBN 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.
