p,p'-DDD-d₈  (Synonyms: 4,4'-DDD-d₈; p,p'-Dichlorodiphenyl dichloroethane-d₈)

p,p'-DDD-d₈ is the deuterium labeled p,p'-DDD[1]. p,p'-DDD (4,4’-DDD) is an organochlorine insecticide, a major metabolite of p,p'-DDT. p,p'-DDD is an agonist at estrogen receptor α(ERα) and ERβ. p,p'-DDD increases DNA damage, apoptosis and necrosis in peripheral blood. p,p'-DDD stimulates cell proliferation in SKBR3 cells. p,p'-DDD activates the AP-1 transcription factor. p,p'-DDD decreases sleep times of barbiturates and steroids in rats^{[1][2][3][4][5]}.

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
