The endothelin receptor antagonist CPU0213 is more effective than aminoguanidine to attenuate isoproterenol-induced vascular abnormality by suppressing overexpression of NADPH oxidase [correction of oxidas], ETA, ETB, and MMP9 in the vasculature.

An increase in reactive oxygen species (ROS) through NADPH oxidase activation frequently follows stress that activates beta-adrenoreceptors, leading to deterioration of cardiovascular disease. We hypothesized that upregulation of NADPH oxidase in the vasculature causes mild vascular spasm subsequent to chronic isoproterenol (ISO) administration, correlating significantly with activation of both ETA and ETB receptors. We tested whether the dual endothelin receptor antagonist CPU0213 is effective… CONTINUE READING
