Abstract
This study is focused on the effect of the antifungal drug clotrimazole (CLT), also possessing anti-malarial and anticancer activities, on hemin-induced hemolysis and changes in ion permeability and filter-ability of human erythrocytes. In the presence of 10 μM clotrimazole, the hemolytic response of erythrocytes to exogenous hemin at concentrations as low as 2–8 μM was considerably potentiated and their filterability, as measured by passing them through a 5-μm nuclepore filter, dropped sharply. Flavonoids quercetin (Q) and taxifolin (DHQ), unlike the standard antioxidant Trolox, abolished the effects of clotrimazole, suggesting that protection of hemin-treated erythrocytes by flavonoids is not related to their antioxidant properties.
