Abstract:
19 cinnamamide/ester-triazole compounds were designed, synthesized and evaluated for their anti-Alzheimer's disease (AD) activity. Among them, compound
4f displayed excellent anti-
β-amyloid protein (A
β)-mediated cytotoxicity (EC
50 = 2.03 ± 2.45 μmol·L
-1) in APPswe cells and acetylcholinesterase inhibiton (IC
50 = 4.88 ± 4.70 μmol·L
-1). Further study indicated that, at dosages of (1, 5 and 25 mg·kg
-1), compound
4f was effective in improving spatial learning and memory deficits in A
β1-42-impaired mice, which was achieved by promoting the nonamyloidogenic signaling and inhibiting the amyloidogenic pathway, along with the suppression of A
β-induced Tau phosphorylation. All animal experiments in this study were approved by the Experimental Animal Care and Use Committee of the Institute of Medicinal Biotechnology (IMB-20220908D701). In conclusion, compound
4f holds promise as a lead candidate for AD treatment, and the present study lays the foundation for its subsequent development.
