sulfaphenazole

Description: Sulfaphenazole, an antibiotic, is a novel potent and specific inhibitor of CYP2C9 that can block atherogenic and pro-inflammatory effects of linoleic acid (increase in oxidative stress and activation of AP-1) mediated by CYP2C9. Treatment of intracerebral hemorrhage is often pointless, although considerable effort has been devoted to developing treatments for ischemic stroke. Sulfaphenazole (SPZ) has a different mechanism such as reactive oxygen species scavenging, in addition to the inhibition of superoxide production by cytochrome P450. Systemic SPZ treatment after intracerebral hemorrhage reduces striatal dysfunction, the elevation of lipid peroxidation, and brain edema in the rat. These results suggest that SPZ is a potentially effective therapeutic approach for intracerebral hemorrhage as the effect of SPZ was initiated for either 1 h or 3 d post-intracerebral hemorrhage.
