用途
使用
One of the thyroid hormones involved in the maintenance of metabolic homeostasis. Synthesized and stored as amino acid residues of thyroglobulin, the major protein component of the thyroid follicular colloid. Synthesis and secretion are regulated by the pituitary hormone (TSH). Deiodinated in peripheral tissues to the active metabolite, liothyronine. The D-form has very little activity as a thyroid hormone, but has been used to treat hyperlipidemia.
製法・合成法
純化方法
Recrystallise D-thyroxine from H2O (needles) or from an ammonical solution by dilution with H2O, MeOH or Me2CO. It has also been purified by dissolving ~6.5 g in a mixture of MeOH (200mL) and 2N HCl (20mL), adding charcoal, filtering then adding NaOAc solution to pH 6. On standing the thyroxine separates, it is filtered off, washed with MeOH then Me2CO and dried in vacuo. N-Formyl-D-thyroxine has m 210o and [] 21 -26.9o (c 5, EtOH). (±)-Thyroxine has m 256o and is purified in the same way. [Nahm & Siedel Chem Ber 96 1 1963, Salter Biochem J 24 471 1930, Beilstein 14 I 671, 14 II 384, 14 III 1566, 14 IV 2374.]
