the best candidate, from which one synthesized compound displayed micromolar activity. Molecular dynamics-based optimization was performed on this hit, and thirty derivatives were designed in silico, synthesized and evaluated on their capacity to inhibit dengue virus entry into the host cell. Four compounds were found to be potent antiviral compounds in the low-micromolar range. The assessment of drug-like

We investigated a group of 2-benzylpiperidin-N-benzylpyrimidin-4-amines with various electron-withdrawing or electron-donating groups (EWGs or EDGs, respectively) as multi-targeted Alzheimer's disease (AD) therapeutics. The synthesized derivatives were screened for anti-cholinesterase (AChE and BuChE), anti-A beta-aggregation (AChE- and self-induced) and anti-beta-secretase (BACE-1) activities in an effort to identify lead, multifunctional candidates as part of our multi-targeted approach to treat AD. Biological assessment revealed that the nature of the substituent on the C-4 benzylamine group (e.g., halogen vs methoxy-based) greatly affected the biological profile. In vitro screening identified N-2-(1-benzylpiperidin-4-yl)-N-4-(3,4-dimethoxybenzyl) pyrimidine-2,4-diamine (7h) as the lead candidate with a dual ChE (AChE IC50 = 9.9 mu M; BuChE IC50 = 11.4 mu M), A beta-aggregation (AChE-induced = 59.3%; self-induced = 17.4% at 100 mu M) and BACE-1 (34% inhibition at 10 mu M) inhibitory profile along with good cell viability (% neuroblastoma cell viability at 40 mu M = 81.0%). Molecular modeling studies indicate that a central pyrimidine-2,4-diamine ring serves as a suitable template to develop novel small molecule candidates to target multiple pathological routes in AD.
