Multitargeted hybrids of N-benzylpiperidine and substituted 5-phenyl-1,3,4-oxadiazoles were designed, synthesized, and evaluated against Alzheimer’s disease (AD). Tested compounds exhibited moderate to excellent inhibition against human acetylcholinesterase (hAChE), butyrylcholinesterase (hBChE), and beta-secretase-1 (hBACE-1). The potential leads 6g and 10f exhibited balanced inhibitory profiles against
N-苄基哌啶与取代的5-苯基-1,3,4-恶二唑的多靶点杂种被设计,合成并针对阿尔茨海默氏病(AD)进行了评估。被测化合物对人乙酰胆碱酯酶(hAChE),丁酰胆碱酯酶(hBChE)和β-分泌酶-1(hBACE-1)表现出中度至极强的抑制作用。潜在的铅6g和10f对所有靶标均表现出平衡的抑制特性,碘化丙啶从hAChE的外围阴离子位点大量置换。混合动力车6g和10f还引起了跨越血脑屏障的有利渗透,并且没有针对SH-SY5Y神经母细胞瘤细胞的神经毒性作用。在基于硫黄素T的自体和AChE诱导的实验中,这两种情况均导致Aβ聚集显着分解。在Y迷宫测试中,化合物6g和10f改善了东pol碱所致的认知功能障碍。大鼠脑匀浆的离体研究确定了两种化合物均降低了AChE水平和抗氧化活性。复方6g免疫印迹和免疫组化分析也证实了在莫里斯水迷宫测试中Aβ引起的认知功能障碍的显着改善,其中Aβ和BACE-1蛋白的表达下调
