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

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. 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.

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.

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

Thyroid hormone has been recently shown to induce tumor growth and angiogenesis via a plasma-membrane hormone receptor on integrin alphaVbeta3. The receptor is at or near the Arg-Gly-Asp (RGD) recognition site on the integrin that is important to extracellular matrix

Tetraiodothyroacetic acid (tetrac) blocks angiogenic and tumor cell proliferation actions of thyroid hormone initiated at the cell surface hormone receptor on integrin alphavbeta3. Tetrac also inhibits angiogenesis initiated by vascular endothelial growth factor and basic fibroblast growth factor. We tested
