| Research Abstract |
In this study, we found that halogenated environmental chemicals substituted hydroxyl group and halogen atom on a phenyl ring inhibited iodotyrosine deiodinase (IYD). IYD-inhibitory agents included polychlorinated biphenyls, polybrominated diphenyl ethers, pharmaceuticals, antiparasitics for animal use, agrichemicals and food colorants. These chemicals may disturb thyroid hormone homeostasis via inhibition of IYD activity.
