Abstract:
:Retinal vein occlusion (RVO) is an intractable eye disease that results in reduced visual acuity, associated with retinal ischemia, hemorrhage, and edema. RVO results in excessive ROS production in the retina, causing inflammation and retinal edema. A free radical scavenger, 4-(4-acetylpiperazin-1-yl)-2-(1H-imidazole-1-yl) aniline (NSP-116), has been reported to demonstrate antioxidative effects and prevent ROS production in the retina. Therefore, NSP-116 may represent a useful drug for treating the pathological symptoms of RVO, such as retinal edema and ischemic symptoms. This study aimed to investigate the effects of NSP-116 in a murine model of RVO. We evaluated the thickness of the retinal layer and the size of the non-perfused area following the oral administration of NSP-116. Moreover, we used western blot analysis to examine the expression levels of vascular endothelial growth factor (VEGF) and tumor necrosis factor (TNF)-α, after NSP-116 administration, and examined the localization of 8-hydroxy-2'-deoxyguanosine (8-OHdG), by immunostaining. The findings indicate that NSP-116 suppressed retinal edema and expansion the non-perfused area by suppressing the increased expression of VEGF, TNF-α, and 8-OHdG in the murine RVO model. In conclusion, the oral administration of NSP-116 may serve as an effective pharmacological treatment for the pathological symptoms of RVO.
