Opis

Application

3,3′,5,5′-Tetraiodothyroacetic acid has been used:

• as a positive control to study the effects of ioxynil (IOX)
• diethylstilbestrol (DES) exposure on zebrafish embryos[1]
• to study its effects on long-term potentiation (LTP) and long-term depression (LTD) in the dentate gyrus in urethane-anesthetized male rats[2]
• to determine its influence on the actions of thyroid-stimulating hormone
• thyroid-stimulating immunoglobulins in orbital fibroblast[3]

Biochem/physiol Actions

3,3′,5,5′-Tetraiodothyroacetic acid (Tetrac) is a deaminated analog of L-thyroxine (T4). It prevents the pro-angiogenesis actions of T4 and 3,5,3′-triiodo-L-thyronine.[4] It is a thyrointegrin receptor antagonist.[5] Tetrac prevents the binding of thyroid hormones.[6]

Studies in rats have reported that Tetrac may regulate TSH secretion under in vivo conditions¹.

Preparation Note

3,3′,5,5′-Tetraiodothyroacetic acid is soluble in acetone at 19.60 - 20.40 mg/ml and yields a clear, faint yellow to yellow solution.
