Abstract:
A new series of structurally rigid donepezil analogues was designed, synthesized and evaluated as potential multi-target-directed ligands (MTDLs) against neurodegenerative diseases. The investigated compounds 10-13 displayed dual AChE and BACE-1 inhibitory activities in comparison to donepezil, the FDA-approved drug. The hybrid compound 13 bearing 2-aminoquinoline scaffold exhibited potent AChE inhibition (IC50 value of 14.7 nM) and BACE-1 inhibition (IC50 value of 13.1 nM). Molecular modeling studies were employed to reveal potential dual binding mode of 13 to AChE and BACE-1. The effect of the investigated compounds on the viability of SH-SY5Y neuroblastoma cells and their ability to cross the blood-brain barrier (BBB) in PAMPA-BBB assay were further studied.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
