Abstract It is hypothesized that the teratogen di(2-ethylhexyl) phthalate (DEHP) acts by in vivo hydrolysis to 2-ethylhexanol (2-EHXO), which in turn is metabolized to 2-ethylhexanoic acid (2-EHXA), the proximate teratogen. Teratological studies were conducted with Wistar rats, with administration of these agents on day 12 of gestation. On an equimolar basis DEHP was least potent, 2-EHXO was intermediate, and 2-EXHA was the most potent of the three agents, which is consistent with the hypothesis. Similarity in the types of defects found with these agents also suggests a common mechanism, with 2-EHXA as the proximate teratogen. All three agents were potentiated by caffeine. Valproic acid, which is an isomer of 2-EXHA, also produced similar defects, and was approximately twice as potent as 2-EHXA.
