A series of Tacrine-Homoisoflavonoid hybrids were designed, synthesised and evaluated as inhibitors of cholinesterases (ChEs) and human monoamine oxidases (MAOs). Most of the compounds were found to be potent against both ChEs and MAO-B. Among these hybrids, compound 8b, with a 6 carbon linker between tacrine and (E)-7-hydroxy-3-(4-methoxybenzylidene)chroman-4-one, proved to be the most potent against AChE and MAO-B with IC50 values of 67.9 nM and 0.401 mu M, respectively. This compound was observed to cross the blood-brain barrier (BBB) in a parallel artificial membrane permeation assay for the BBB (PAMPA-BBB). The results indicated that compound 8b is an excellent multifunctional promising compound for development of novel drugs for Alzheimer's disease (AD). (C) 2013 Elsevier Ltd. All rights reserved.
