Herein we describe the synthesis and in vitro biological evaluation of thirteen new, racemic, diversely functionalized imidazo pyranotacrines as non-hepatotoxic, multipotent tacrine analogues. Among these compounds, 1-(5-amino-2-methyl-4-(1-methyl-1H-imidazol-2-yl)-6,7,8,9-tetrahydro-4H-pyrano[2,3-b]quinolin-3-yl)ethan-1-one (4) is non-hepatotoxic (cell viability assay on HepG2 cells), a selective but moderately potent EeAChE inhibitor (IC50 = 38.7 ± 1.7 μM), and a very potent antioxidant agent on the basis of the ORAC test (2.31 ± 0.29 μmol·Trolox/μmol compound).
在此我们描述了十三种新的、外消旋且功能多样化的咪唑吡喃他克林的合成和体外生物评估,这些化合物被认为是非肝毒性的多能他克林类似物。在这些化合物中,1-(5-氨基-2-甲基-4-(1-甲基-1H-咪唑-2-基)-6,7,8,9-四氢-4H-吡喃[2,3-b]喹啉-3-基)乙酮(4)被认为是非肝毒性的(在HepG2细胞上的细胞活力测定),是一种选择性但具有中等效力的EeAChE抑制剂(IC50 = 38.7 ± 1.7 μM),并且在ORAC测试中显示出非常强的抗氧化活性(2.31 ± 0.29 μmol·Trolox/μmol化合物)。
