respectively) as well as anti-necrotic, anti-apoptotic, and antioxidant activities (EC50 = 11.2 ± 3.94 μM), which were measured by its capacity to reduce superoxide production in human neuroblastoma SH-SY5Y cell cultures, followed by mononitrone BPMN3, with one N-Bn radical, and BPMN2, with only one N-tert-Bu substituent. The antioxidant activity of BPNs1-5 has also been analyzed for their capacity to
在此,我们报告了 1,1'-联苯硝酮 ( BPNs ) 1 – 5作为由市售 [1,1'-联苯]-4-甲醛制备的 α-苯基-N-叔丁基硝酮类似物的神经保护和抗氧化活性和[1,1'-联苯]-4,4'-二甲醛。已在人神经母细胞瘤 SH-SY5Y 细胞的缺氧-葡萄糖体外缺血模型中针对寡霉素 A/鱼藤酮测量了BPN 1 - 5的神经保护作用。我们的结果表明, BPNs 1 – 5比 α-苯基-N-叔丁基硝酮 ( PBN ) 具有更好的神经保护和抗氧化特性,并且它们与N-乙酰基-L-半胱氨酸 ( NAC ) 非常相似,NAC 是一种良好的神经保护剂。已知的抗氧化剂。在所研究的硝酮中,同型双硝酮BPHBN5在硝酮基序上带有两个N-叔-Bu 基团,具有最佳的神经保护能力(EC 50 = 13.16 ± 1.65 和 25.5 ± 3.93 μM),以对抗由硝酮引起的代谢活性降低。分别通过体外缺血模型中的
