| Hazard Information | Back Directory | [Uses]
It has been prepared for testing as possible antithyroid. It showed some thyromimetic activity. | [Uses]
O-(4-Hydroxy-3,5-diiodophenyl)-3,5-diiodo-b-hydroxy-L-tyrosine is a Levothyroxine impurity of Thyroxine (T425600), which is one of the thyroid hormones involved in the maintenance of metabolic homeostasis. Thyroxine is deiodinated in peripheral tissues to the active metabolite, liothyronine, which has been used to treat hyperlipidemia. |
