General description

2,2′-Dihydroxyazobenzene is a small molecule inhibitor of ADP ribosyl cyclase and it attenuates angiotensin (Ang) II-induced hypertrophic responses. 2,2′-Dihydroxyazobenzene is formed during the oxidation of diclofenac by myeloperoxidase/hydrogen peroxide.

Application

2,2′-Dihydroxyazobenzene was used as complexing reagent in determination of aluminum in human serum by ion-pair reversed-phase partition HPLC.

An ion-pair reversed-phase partition high-performance liquid chromatography-spectrophotometric method is described for the determination of aluminum in human serum, based on its complexation with 2,2'-dihydroxyazobenzene. The chelate is separated on C18-bonded silica packing by using an aqueous methanol mobile phase containing

Diclofenac is associated with a low, but significant, incidence of hepatotoxicity and bone marrow toxicity. It has been suggested that this could be due to a reactive acyl glucuronide. An alternative hypothesis is that an oxidative reactive metabolite could be
