    Although alterations in kidney tissue structure, redox balance and endothelial function are reversible in stages 1, 2 and 3, these conditions are irreversible once reaching stages 4 and 5 [ 2 ], having deteriorated the antioxidant defenses beyond repair. The complications in these cases are mainly caused by the elevated production of reactive oxygen species ROS and reactive nitrogen species RNS , thus altering the oxidant—antioxidant balance. ROS and RNS are an integral part of metabolism, stress and inflammation [ 6 ] and have been extensively studied in disorders of the renal system. Since numerous reports confirm the importance of the oxidative state in renal tissue, antioxidant therapy has become a part of the preventive and regulatory treatment for CKD, delaying its progression KDOQI 3 and consequently the appearance of the terminal phase TCKD [ 7 , 8 ]. Factors that promote oxidative imbalance are a fundamental part of the basic pathophysiological mechanisms of renal disorders. Ischemic or toxic phenomena, which can engender acute damage to the tubule, may be accompanied by excessive production of ROS. In chronic kidney damage of metabolic origin e. The natural defense system against oxidative stress consists mainly of nonenzymatic antioxidants e. All these elements are closely related to the progression of the different stages of CKD [ 4 ]. In patients with damaged renal function, excessive levels of ROS and other uremic toxins of an oxidizing nature disrupt the redox balance and overcome the capacity of the antioxidant defense [ 10 ]. The different isoforms of Nox are Nox1, Nox2 and Nox4 [ 11 ], the latter showing greater expression in endothelial cells than Nox2 [ 10 ].

    Under conditions of oxidative stress, however, Nox2 [ 12 ] generates eight times more of the superoxide anion , increasing its level 2 to 3 times.

    Hence, reaches a greater concentration than other isoforms in endothelial cells [ 13 ]. At the level of arterioles interlobular, arcuate, afferent, efferent and rectal vessels , the resulting endothelial dysfunction is characterized by altered regulation of vasodilation and vascular tone, leading to ischemia and finally to renal parenchymal necrosis.

    Ang II is implicated in the development of various cardiovascular and renal pathologies. Apart from being synthesized by the renin—angiotensin—aldosterone system RAAS , it is produced by alternate enzymatic pathways mediated by cathepsin G, chymase, chymostatin-sensitive angiotensin-generating enzyme CAGE and tissue plasminogen activator T-PA.

    Hence, each of these pathways can indirectly contribute to increased vascular tone [ 16 ].

    On the other hand, 4-hydroxymethoxyacetophenone apocynin , isolated from the medicinal plant Picrorhiza kurroa, has gained recognition as an inhibitor of Nox. Although the mechanism of action is not yet completely clear, it is known that apocynin inhibits assembly of the cytoplasmic subunits of Nox: p47phox, p67phox and p21rac with gp91phox and p22phox of membranes [ 17 , 18 ].

    Apocynin binds to p47phox in the same region in which the latter protein binds to p22phox. Due to its effects on redox balance and vascular tone, the Nox enzyme has become an important therapeutic target. The probable decrease in production was explored as well as its effect on the pathophysiology of CKD.


    This investigation is part of the current effort to test new inhibitors of Nox for their possible renoprotective effect. The long-term aim is to improve the quality of life of patients while reducing the morbidity and mortality of CDK. Materials and methods 2.
