Interventionantioxidant drug EUK-8
Alternate Name
OrganismCaenorhabditis elegans
Aging PhenotypeLife-span extension
Allele TypeN/A
DescriptionTreatment of worms with 5 mM EUK-8 extended mean and maximum life-span by about 50% (Melov et al., 2000).
In contrast to the results of Melov et al., (2000), Keaney and Gems (2003) report that treatment with 5 mM EUK-8 shortens life-span by approximately 83%. These opposing observations may be due to different methods used for administering the drug (e.g. daily vs. every-other-day treatment) and/or different compound sources.
Gene FunctionEUK-8 acts as a superoxide dismutase and catalase mimetic (Baker et al., 1998).
Other PhenotypesTreatment with EUK-8 does not affect fertility or body size (Melov et al., 2000).

EUK-8 treatment resulted in a shortened life-span in the house fly, Musca domestica (Bayne and Sohal, 2002).
