| Biochem/physiol Actions: | Abnormal thiol redox state (TRS) is involved in the pathogenesis of a variety of diseases, such as chronic heart disease and atherosclerosis, rheumatoid arthritis , AIDS , Parkinson disease, Alzheimer disease, etc. Thus there is a need for tools capable of regulating TRS. Glutathione reductase (GR) is a critical enzyme in the homeostasis of TRS. Thus selective GR inhibitor would be a valuable research tool in studying TRS-related processes. Carmustine (#C0400) an anticancer drug is commonly used as GR inhibitor (IC50~470 microM). 2-AAPA is novel, potent cell-penetrable GR inhibitor. The compound is quite selective. But small reduction of activity for GP and GST was observed at 0.1mM concentration of 2-AAPT. |
| Biochem/physiol Actions: | Glutathione reductase (GR) is a critical enzyme in the homeostasis of cellular thiol redox state. 2-AAPA is potent, selective, cell-permeable GR inhibitor, a valuable research tool in studying processes related to thiol redox state. For example, it was used in a study of the relationship between thiol redox state and overall redox state. In addition to the expected decrease in GSH and increase in GSSG, 2-AAPA increased the ratios of NAD(P)H/NAD(P)+. Significant protein glutathionylation was also observed. |
