用途有機合成原料、医薬原料。
説明Diiodotyrosine does not possess pronounced hormonal activity. However, it stops production of thyrotropic hormone by the anterior lobe of the hypophysis, which activates thyroid gland activity.
使用It is used for hyperthyroid forms of endemic and sporadic goiters, diffuse, toxic goiters, and other illnesses accompanied by thyrotoxicity.
純化方法It forms crystals from H2O [solubility (g/L): 0.204 at 0o, 1.86 at 50o, 5.6 at 75o and 17.0 at 100o]. Also recrystallise it from 50% or 70% EtOH. When boiled in EtOH the crystals swell, and on further boiling a gelatinous precipitate is formed [Harrington Biochem J 22 1434 1928, Jurd J Am Chem Soc 77 5747 1955]. It also crystallises from cold dilute ammonia on adding acetic acid to pH 6. [Beilstein 14 IV 2370.]
