How to use

In Vitro:

TrxR inhibitor D9 (0.1-1 μM; 72 h) inhibits the cell proliferation with IC50s of 0.03 and 0.1 μM for MCF-7 and HT-29 cells, respectively. TrxR inhibitor D9 (72 h) completely inhibits all cancer cells (A549, KB, MDA MB-231, HeLa, MCF-7 and HT-29) viability at the concentration of 0.60 μM, and the IC50s of all cancer cells could be as low as 0.55 μM, and dose not significantly affects normal cells viability. TrxR inhibitor D9 (0.8 μM; 4 and 8 h) induces HT-29 cells necrosis/apoptosis. TrxR inhibitor D9 (2-20 nM; 1-60 s) inhibits TrxR activity in a concentration-dependent manner. TrxR inhibitor D9 (1-1000 nM) does not significantly inhibits the catalytic activity of glutathione reductase (GR) even when the concentration increases to more than 1000 nM. TrxR inhibitor D9 (0.4 μM) could effectively avoid the ligand exchange with albumin.

In Vivo:

TrxR inhibitor D9 (5 mg/kg; i.v. once every 2 d for 15 d) effectively inhibits the growth of tumors in mice.
