HQNO is a NADH oxidase inhibitor.
The NADPH oxidase, a membrane-bound enzyme complex facing the extracellular space, can be found in the plasma membrane and in the membranes of phagosomes used by neutrophil white blood cells to engulf microorganisms. Isoforms are designated NOX1, NOX2, NOX3, as well as NOX4.
In vitro: Previous study found that HQNO could inhibit the Na+-dependent NADH oxidase but had very limited effect on the NA+-independent activity of mutant membranes. Moreover, the NADH:quinone oxidoreductase was observed to be the Na+-dependent HQNO-sensitive site of the NADH oxidase. In addition, HQNO was found to be able to cause a strong inhibition of the Na+ pump with limited effect on the overall H+ extrusion by respiration in the wild type cells. The inhibition of the Na+ pump by HQNO could be overcome by oxidized but not reduced TMPD. The electron flow NADH to oxygen appeared to bypass the HQNO-sensitive site and energize the Na+ pump in the presence of oxidised TMPD [1].
In vivo: Up to now, there is no animal in vivo data reported.
Clinical trial: So far, no clinical study has been conducted.

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
