Introduction of 67-30-1 :

Tetrac (Tetraiodothyroacetic acid), a derivative of L-thyroxine (T4), is a thyrointegrin receptor antagonist. Tetrac blocks the actions of T4 and 3,5,3'-triiodo-L-thyronine (T3) at the cell surface receptor for thyroid hormone on integrin αvβ3. Tetra has anti-angiogenic and anti-tumor activities[1][2]. In Vitro: Tetrac (0.01-1 μM; 2-6 d) induces anti-proliferation in HT-29 and HCT116 cells with different K-RAS status[3].
Tetrac (0.1 μM; 30 min) inhibits activation of ERK1/2 in HT-29 and HCT116 cells[3].
Tetrac (0.1 μM; 24 h) inhibits expression of CCND1 and c-Myc, but promotes expression of CASP2 and THBS1[3]. In Vivo: Tetrac (35 μg; p.o. for 40 days) inhibits tumor inoculation, growth and integrin expression in mice[4].
