By targeting the dual active sites of acetylcholinesterase (AChE), a new series of berberine derivatives was designed, synthesized, and evaluated as AChE inhibitors. Most of the derivatives inhibited AChE in the sub-micromolar range. Compound 8c, berberine linked with phenol by a 4-carbon spacer, showed the most potent inhibition of AChE. A kinetic study of AChE and BuChE indicated that a mix-competitive binding mode existed for these berberine derivatives. Molecular modeling studies confirmed that these hybrids target both the catalytic active site (CAS) and the peripheral anionic site (PAS) of AChE. This is the first report where AChE inhibitory activity has been associated with berberine as a lead molecule. (C) 2009 Elsevier Ltd. All rights reserved.

Alzheimer's disease (AD) is a multifactorial syndrome with several target proteins contributing to its etiology. To confront AD, an innovative strategy is to design single chemical entities able to simultaneously modulate more than one target. Here, we present compounds that inhibit acety1cholinesterase and NMDA receptor activity. Furthermore, these compounds inhibit AChE-induced AP aggregation and display antioxidant properties, emerging as lead candidates for treating AD.
