Thioredoxin-1 (Trx-1) inhibitor; irreversibly inactivates Trx-1 as a substrate for reduction by thioredoxin reductase (TR); competitively inhibits the reduction of Trx-1 by TR (Ki = 30.8 μM). Attenuates expression of HIF-1α, VEGF and iNOS (IC50 values are 7.2, 10.4 and 18.1 μM respectively). Exhibits antitumor activity; directly inhibits tubulin in vitro and decreases tumor microvessel density in vivo.

Preparing Stock Solutions
The following data is based on the product molecular weight 188.31. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||5.31 mL||26.55 mL||53.1 mL|
|5 mM||1.06 mL||5.31 mL||10.62 mL|
|10 mM||0.53 mL||2.66 mL||5.31 mL|
|50 mM||0.11 mL||0.53 mL||1.06 mL|
