Herein we describe the synthesis and in vitro biological evaluation of thirteen new, racemic, diversely functionalized 2-chloroquinolin-3-yl substituted PyranoTacrines (PTs) as multipotent tacrine analogues for Alzheimer's disease (AD) therapy. Among these compounds, 1-(5-amino-4-(2-chloro-7-methoxyquinolin-3-yl)-2-methyl-6,7,8,9-tetrahydro-4H-pyrano [2,3-b]quinolin-3-yl)éthanone (9) and ethyl 5-a
在本文中,我们描述了十三种新的,外消旋的,功能多样的2-氯喹啉-3-基取代的吡咯烷酮(PTs)的合成和体外生物学评估,这些药物是用于阿尔茨海默氏病(AD)治疗的多能他克林类似物。在这些化合物中,1-(5-氨基-4-(2-氯-7-甲氧基喹啉-3-基)-2-甲基-6,7,8,9-四氢-4 H-吡喃[2,3- b ]喹啉-3-基)乙酮(9)和乙基5-氨基-4-(2-氯喹啉-3-基)-2-甲基-6,7,8,9-四氢-4 H-吡喃[2] ,3- b ]喹啉-3-羧酸乙酯(4)被认为是在人神经母细胞SHSY5Y非神经毒性剂。化合物9(IC 50 = 0.47±0.13μM)和4种(IC 50 = 0.48±0.05μM)是有效的混合型(9:Ki = 0.0142±0.003μM)和选择性Ee AChE抑制剂,在催化和外围均具有结合力酶的阴离子位点。化合物9和4是氧化应激诱导的SHSY5Y细胞活力降
