The flavonoid compound scutellarin (Scu) is a traditional Chinese medicine used to treat a variety of diseases; however, the use of scutellarein (Scue), the hydrolysate of Scu, and its mechanisms of action in Alzheimer's disease (AD) have not been fully elucidated. In the present study, the effects of Scue on amyloid β (Aβ)-induced AD-like pathology were investigated. An model of inflammation and an aged rat model were used to confirm the effects of Scue. MTT assays and flow cytometry were used to assess the effects of Scue on cell viability and apoptosis, respectively. A Morris water maze was used to evaluate spatial learning and memory, and the levels of Aβ deposition, superoxide dismutase, malondialdehyde, apoptosis, neuro-inflammatory factors and nuclear factor-κB (NF-κB) activation in hippocampal tissues were measured to determine the effect of Scue in AD. Scue may be protective, as it decreased the apoptosis of hippocampal cells , inhibited Aβ-induced cognitive impairment, suppressed hippocampal neuro-inflammation and suppressed activation of NF-κB . Therefore, Scue may be a useful agent for the treatment of Aβ-associated pathology in the central nervous system through inhibition of the protein kinase B/NF-κB signaling pathway and thus, future studies are required to investigate the efficacy of Scue in patients with AD.
黄酮类化合物灯盏花乙素(Scu)是一种用于治疗多种疾病的传统中药;然而,灯盏花素(Scue)(Scu的水解产物)在阿尔茨海默病(AD)中的应用及其作用机制尚未完全阐明。在本研究中,研究了Scue对淀粉样β蛋白(Aβ)诱导的AD样病理的影响。使用炎症模型和老年大鼠模型来证实Scue的作用。MTT法和流式细胞术分别用于评估Scue对细胞活力和细胞凋亡的影响。使用Morris水迷宫评估空间学习和记忆,并测量海马组织中Aβ沉积、超氧化物歧化酶、丙二醛、细胞凋亡、神经炎症因子和核因子κB(NF-κB)激活水平,以确定Scue在AD中的作用。Scue可能具有保护作用,因为它减少了海马细胞的凋亡,抑制了Aβ诱导的认知障碍,抑制了海马神经炎症并抑制了NF-κB的激活。因此,Scue可能是一种通过抑制蛋白激酶B/NF-κB信号通路治疗中枢神经系统中Aβ相关病理的有效药物,因此,需要进一步研究来调查Scue对AD患者的疗效。
