Multitarget molecules are considered as an effective way for the treatment of AD, instead of the classic one-drug-one-target strategy because of the multifactorial nature of AD. A variety of studies indicate that several enzymes inhibitors can be useful in the treatment of AD, including acetylcholinesterase (AchE), butyrylcholinesterase (BuChE) and monoamine oxidase (MAO). Various substituted quinoxaline-hydrazone derivatives were synthesized, and their activity in vitro were investigated, including AChE/BuChE inhibitory activity and MAOA/B inhibitory activity. Based on the experimental results, compound 5l exhibited good inhibitory potency on both AchE (IC50 = 0.028 +/- 0.001 mu M) and monoamine oxidase B (IC50 = 0.046 +/- 0.002 mu M). Molecular modeling studies showed that 5l could bind to the active site of AChE and MAO-B. Taken together, these results suggested that compound 5l might be a potential multifunctional agent for the treatment of AD.
