(-)-Tiroxina

Descrizione:

(-)-Tiroxina, noto anche come L-tiroxina o T4, è un ormone prodotto dalla ghiandola tiroidea che svolge un ruolo cruciale nella regolazione del metabolismo, della crescita e dello sviluppo nel corpo. È un derivato tetraiodato dell'aminoacido tirosina, caratterizzato dalla presenza di quattro atomi di iodio nella sua struttura. La formula chimica di (-)-Tiroxina è C15H11I4N0 e ha un peso molecolare di circa 776,87 g/mol. Questo composto si trova tipicamente come una polvere cristallina bianca o bianco sporco ed è solubile in acqua e alcol, ma meno solubile nei solventi organici. (-)-Tiroxina funziona legandosi ai recettori degli ormoni tiroidei, influenzando l'espressione genica e i processi metabolici. È comunemente usato in contesti clinici per trattare l'ipotiroidismo e altri disturbi legati alla tiroide. La sua attività è monitorata da vicino, poiché sia la carenza che l'eccesso possono portare a problemi di salute significativi. Il numero CAS 51-48-9 identifica univocamente questo composto nelle banche dati chimiche, facilitando la ricerca e la conformità normativa.

Thyroxine (100% pure T4 reference standard (free of T3))

CAS: 51-48-9

Applications Thyroxine is 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.

Levothyroxine

CAS: 51-48-9

Levothyroxine is a thyroid hormone that is used to treat hypothyroidism. It is taken in tablet form, usually once per day. Levothyroxine therapy can be started with a low dose and increased gradually over time. This drug has been shown to be effective in the treatment of bowel disease, which may be due to its ability to decrease inflammation and increase the movement of stool through the intestines. Levothyroxine has also been shown to have beneficial effects on other autoimmune diseases such as rheumatoid arthritis and congestive heart failure. The use of levothyroxine requires periodic blood sampling for monitoring.
