摘要：The bis-Schiff base of N , N ′-1,10-bis(naringin) triethylenetetraamine ( 1 ) was prepared, as a copper(II) ion chelator, compound 1 was used for Alzheimer’s disease therapy in vitro . The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay of compound 1 showed that this Schiff base could promote PC12 cells proliferation, and also, compound 1 could inhibit Cu 2 -amyloid-β (Aβ) 1–42 mediated cytotoxicity on PC12 cells. The thioflavine T (ThT) assay showed that 1 can effectively attenuate Cu 2 -induced Aβ 1–42 aggregation. In addition, compound 1 is determined to be potent antioxidants on the basis of in vitro antioxidant assay, it can effectively decease the level of reactive oxygen species (ROS) in Cu 2 -Aβ 1–42 -treated PC12 cells and elevate the superoxide dismutase (SOD) activity in Cu 2 -Aβ 1–42 -treated PC12 cells. The results show that N , N ′-1,10-bis(naringin) triethylenetetraamine is a potential agent for therapy of Alzheimer’s disease.
