3,3',5,5'-Tetraiodothyroacetic Acid: A Thyroid Hormone Analogue with Anti-Angiogenesis and Anti-Tumor Growth Effects

3,3',5,5'-Tetraiodothyroacetic acid is a thyroid hormone (L-thyroxine [T0245]) analogue. It is reported that 3,3',5,5'-tetraiodothyroacetic acid acts at a cell surface receptor to block angiogenic and tumor cell proliferation action of thyroid hormones, which have been recently shown to induce tumor growth and angiogenesis.
