Abstract In view of the multifactorial nature of Alzheimer’s disease (AD), multitarget small molecules (MTSM) represent the most potent and attractive therapeutic strategy to design new drugs for Alzheimer’s disease therapy. The new MTSM KojoTacrines (KTs) were designed and synthesized by juxtaposition of selected pharmacophoric motifs from kojic acid and tacrine. Among them, 11-amino-2-(hydroxyme
抽象的 鉴于阿尔茨海默氏病(AD)的多因素性质,多靶标小分子(MTSM)代表了设计用于阿尔茨海默氏病治疗的新药的最有效和有吸引力的治疗策略。通过并置从曲酸和他克林中选择的药效基序来设计和合成新的MTSM KojoTacrines(KTs)。其中,11-氨基-2-(羟甲基)-12-(3-甲氧基苯基)-7,9,10,12-四氢吡喃[2',3':5,6]吡喃并[2,3- b ]喹啉-4(8 H)-one(KT2d)被确定为比他克林具有更低的肝毒性,在更高的浓度下,它是一种中度但选择性的人乙酰胆碱酯酶抑制剂(IC 50= 4.52±0.24μM),以及示出显著神经保护针对甲抗氧化剂(TE = 4.79)β 1-40在3和10μM的浓度。因此,KT2d是AD治疗潜在的新型命中配体,可用于进一步的生物学探索。
