A novel class of 2,4-disubstituted pyrimidines (7a-u, 8a-f, 9a-e) that possess substituents with varying steric and electronic properties at the C-2 and C-4 positions, were designed, synthesized and evaluated as dual cholinesterase and amyloid-beta (A beta)-aggregation inhibitors. In vitro screening identified N-(naphth-1-ylmethyl)-2-(pyrrolidin-1-yl)pyrimidin-4-amine (9a) as the most potent AChE inhibitor (IC50 = 5.5 mu M). Among this class of compounds, 2-(4-methylpiperidin-1-yl)-N-(naphth-1-ylmethyl) pyrimidin-4-amine (9e) was identified as the most potent and selective BuChE inhibitor (IC50 = 2.2 mu M, selectivity index = 11.7) and was about 5.7-fold more potent compared to the commercial, approved reference drug galanthamine (BuChE IC50 = 12.6 mu M). In addition, the selective AChE inhibitor N-benzyl-2-(4-methylpiperazin-1-yl)pyrimidin-4-amine (7d), exhibited good inhibition of hAChE-induced aggregation of A beta(1-40) fibrils (59% inhibition). Furthermore, molecular modeling studies indicate that a central pyrimidine ring serves as a suitable template to develop dual inhibitors of cholinesterase and AChE-induced A beta aggregation thereby targeting multiple pathological routes in AD.
