Produktinformationen "L-Thyroxine-13C9,15N"
L-Thyroxine-13C9,15N is intended for use as an internal standard for the quantification of L-thyroxine (Cay-14116) by GC- or LC-MS. L-Thyroxine is a synthetic form of the thyroid hormone thyroxine. In vivo, L-thyroxine (0.9 and 2.7 µg) inhibits synthesis and release of thyrotropin induced by thyrotropin-releasing hormone (Cay-22917) from the anterior pituitary in mice. It also reverses decreases in levels of circulating thymic serum factor (FTS) and the number of T rosette-forming cells in an old age-induced mouse model of hypothyroidism. Formulations containing L-thyroxine have been used in the treatment of hypothyroidism.Formal Name: O-(4-hydroxy-3,5-diiodophenyl)-3,5-diiodo-L-tyrosine-carboxy,alpha,beta,1,2,3,4,5,6-13C9-15N.
