Application

Sulfaphenazole has been used as a positive control to inhibit cytochrome P450 2C9 (cyp2c9) to quantify Rhodiola rosea inhibition. It has also been used as cytochrome P450 2C9 (cyp2c9) inhibitor in endothelial cells and microsomal preparations.

Biochem/physiol Actions

Antibacterial. Specific inhibitor of CYP2C9. Blocks pro-inflammatory and atherogenic effects of linoleic acid (increase in oxidative stress and activation of AP-1) mediated by CYP2C9. Specific inhibitor of CYP2C9. Blocks pro-inflammatory and atherogenic effects of linoleic acid (increase in oxidative stress and activation of AP-1) mediated by CYP2C9. Inhibits bradykinin-induced tPA release.

Pyridine substituted naphthalenes (e.g., I-III) constitute a class of potent inhibitors of aldosterone synthase (CYP11B2). To overcome the unwanted inhibition of the hepatic enzyme CYP1A2, we aimed at reducing the number of aromatic carbons of these molecules because aromaticity has

Previously, we showed that sulfaphenazole (SUL), an antimicrobial agent that is a potent inhibitor of cytochrome P4502C9, is protective against ischemia-reperfusion (I/R) injury (Ref. 15). The mechanism, however, underlying this cardioprotection, is largely unknown. With evidence that activation of autophagy
