This study investigated whether subacute treatment with 7-chloro-4-(phenylselanyl) quinoline (4-PSQ) presented antioxidant action in oxidative stress associated with aging in different rat tissues. We also investigated whether plasma selenium levels were altered by aging, as well as the contribution of 4-PSQ administration to these levels. Aged Wistar male rats (23month old) were intragastrically treated with 4-PSQ (5mg/kg) for seven days. On the 14th day of the experimental protocol, plasma was collected to determine selenium levels and biochemical markers of renal and hepatic damage. Furthermore, liver, kidney, spleen and cerebral cortex were removed to determine thiobarbituric acid reactive species (TBARS), non-protein thiols (NPSH), glutathione S-transferase (GST), catalase (CAT) and δ-aminolevulinate dehydratase (ALA-D). Our results showed that one or more parameters changed markedly in the liver, kidney, spleen and cerebral cortex of aged rats. Moreover, biochemical markers of renal and hepatic damage and selenium levels are changed in the plasma of aged rats. Treatment with 4-PSQ repaired redox homeostasis in tissues of aged rats, as well as plasma biochemical markers of renal and hepatic damage and selenium levels. In conclusion, 4-PSQ presented an antioxidant effect in tissues of aged rats, restoring selenium levels, and contributing to the restoration of the damage caused by aging. Thus, 4-PSQ could be a potential candidate for the management of age-related oxidative damage, acting as an anti-aging drug.

7-氯-4-(苯基硒基)喹啉作为抗衰老药物对抗衰老大鼠不同组织的氧化损伤的作用。

这项研究调查了7-氯-4-(苯基硒基)喹啉(4-PSQ)亚急性治疗在不同大鼠组织中与衰老相关的氧化应激中是否表现出抗氧化作用。我们还研究了血浆硒水平是否会因衰老而改变,以及4-PSQ给药对这些水平的贡献。将成年的Wistar雄性大鼠(23个月大)用4-PSQ(5mg / kg)进行胃内治疗7天。在实验方案的第14天,收集血浆以确定硒水平以及肾和肝损害的生化标志物。此外,去除肝脏,肾脏,脾脏和大脑皮层,以确定硫代巴比妥酸反应性物种(TBARS),非蛋白硫醇(NPSH),谷胱甘肽S-转移酶(GST),过氧化氢酶(CAT)和δ-氨基乙酰丙酸脱水酶(ALA- D)。我们的结果表明,老年大鼠的肝脏,肾脏,脾脏和大脑皮层中的一个或多个参数发生了明显变化。此外,衰老大鼠血浆中肾脏和肝损伤以及硒水平的生化标志物也发生了变化。4-PSQ处理可修复衰老大鼠组织中的氧化还原稳态,以及肾脏和肝损伤以及硒水平的血浆生化标志物。总之,4-PSQ对衰老大鼠的组织具有抗氧化作用,可恢复硒水平,并有助于恢复衰老所致的损害。因此,4-PSQ可能是抗衰老药物,可用于治疗与年龄相关的氧化损伤。老年大鼠血浆中肾脏和肝损伤以及硒水平的生化标志物发生了变化。4-PSQ处理可修复衰老大鼠组织中的氧化还原稳态,以及肾脏和肝脏损伤以及硒水平的血浆生化标志物。总之,4-PSQ对衰老大鼠的组织具有抗氧化作用,可恢复硒水平,并有助于恢复衰老所致的损害。因此,4-PSQ可能是抗衰老药物,可用于治疗与年龄相关的氧化损伤。老年大鼠血浆中肾脏和肝损伤以及硒水平的生化标志物发生了变化。4-PSQ处理可修复衰老大鼠组织中的氧化还原稳态,以及肾脏和肝脏损伤以及硒水平的血浆生化标志物。总之,4-PSQ对衰老大鼠的组织具有抗氧化作用,可恢复硒水平,并有助于恢复衰老所致的损害。因此,4-PSQ可能是抗衰老药物,可用于治疗与年龄相关的氧化损伤。4-PSQ对衰老大鼠的组织具有抗氧化作用,可恢复硒水平,并有助于恢复衰老所致的损害。因此,4-PSQ可能是抗衰老药物,可用于治疗与年龄相关的氧化损伤。4-PSQ对衰老大鼠的组织具有抗氧化作用,可恢复硒水平,并有助于恢复衰老造成的损害。因此,4-PSQ可能是抗衰老药物,可用于治疗与年龄相关的氧化损伤。
