A series of homoisoflavonoid Mannich base derivatives were designed, synthesized and evaluated as multifunctional agents against Alzheimer’s disease. It demonstrated that most of the derivatives were selective AChE and MAO-B dual inhibitors with good multifunctional properties. Among them, compound 10d displayed the comprehensive advantages, with excellent AChE and MAO-B inhibitory activities (IC50 = 2.49 ± 0.08 nM and 1.74 ± 0.0581 μM, respectively), good self- and Cu2+-induced Aβ1-42 aggregation inhibitory potency, antioxidant activity, biometal chelating ability and high BBB permeability. These multifunctional properties make 10d as an excellent candidate for the development of efficient drugs against AD.
