Intervention2-mercaptoethylamine hydrochloride
Alternate Name2-MEA
OrganismMus musculus
Aging PhenotypeLife-span extension
Allele TypeN/A
StrainLAF
DescriptionAddition of 1% by weight 2-MEA to the diet of male LAF mice, started shortly after weaning, increases average life-span by approximately 30%. This regimen has no effect on maximum life-span. (Harman, 1968; Harman, 2001).
Gene Function2-MEA is an antioxidant
Other PhenotypesAddition of 2-MEA to the maternal diet of female mice increased the life-span of male and female offspring by 15% and 8%, respectively (Harman and Eddy, 1979; Harman, 2001). Addition of an antioxidant mixture containing ethoxyquin and 2-MEA to the diet of calorically restricted mice shortened life-span approximately 20% (Harris, et al., 1990).
