| Bioactivity | 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]. |
| Invitro | 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].
