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
  • to study its effects on long-term potentiation (LTP) and long-term depression (LTD) in the dentate gyrus in urethane-anesthetized male rats
  • to determine its influence on the actions of thyroid-stimulating hormone
  • thyroid-stimulating immunoglobulins in orbital fibroblast

Actions biochimiques/physiologiques

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. It is a thyrointegrin receptor antagonist. Tetrac prevents the binding of thyroid hormones.
Studies in rats have reported that Tetrac may regulate TSH secretion under in vivo conditions1.

Notes préparatoires

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.

Plasma membrane integrin αvβ3 is a cell surface receptor for thyroid hormone at which nongenomic actions are initiated. L-thyroxine (T₄) and 3,3',5-triiodo-L-thyronine (T₃) promote angiogenesis and tumor cell proliferation via the receptor. Tetraiodothyroacetic acid (tetrac), a deaminated T₄ derivative, blocks
