thyroxine

L-Thyroxine (NSC 36397) is the major hormone derived from the thyroid gland. L-Thyroxine (NSC 36397) is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. L-Thyroxine (NSC 36397) is released from thyroglobulin by proteolysis and secreted into the blood. L-Thyroxine (NSC 36397) is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.

D-Thyroxine (Dextroxin) could lower cholesterol and also increases hepatic lipase which in turn improves utilization of triglycerides, leading to improve apolipoprotein E cholesterol particles.

L-Thyroxine sodium salt pentahydrate (Sodium levothyroxine pentahydrate) is a thyroid hormone with anticholesterol activity that inhibits the release of thyroid hormones from thyroid cancer nodules and is used in immune and endocrine disorders such as hypothyroidism, myxedema, cretinism and obesity. diseases, such as hypothyroidism, myxedema, cretinism and obesity.

Thyroxine sulfate is a sulfoconjugated derivative of Thyroxine and is also a metabolite of Thyroxine.

Dextrothyroxine sodium is the dextrorotary isomer of thyroxine.

Levothyroxine acyl glucuronide (Thyroxine Acyl-β-D-glucuronide) is the acyl glucuronide conjugate of thyroxine (T4), an endogenous metabolite.

D-Phenylalanine, a necessary aromatic amino acid, is a precursor of thyroxine, dopamine, melanin, and noradrenaline (norepinephrine).

Tetrac (Tetraiodothyroacetic acid) is a derivative of L-thyroxine (T4), a thyroxine integrin receptor antagonist.Tetrac induces antiproliferation by blocking EGFR-mediated cell signaling in colorectal cancer cells.Tetrac blocks the effects of T4 and 3,5,3'-triiodo-L-thyronine (T3) on the cell-surface thyroxine integrin αvβ3 receptors.Tetra has anti-angiogenic, anti-tumor activity and pro-apoptotic activity.
