Parkinson's disease (PD) is an age-associated neurodegenerative movement disorder that leads to loss of dopaminergic neurons and motor deficits. Approaches to neuroprotection and symptom management in PD include use of monoamine oxidase B (MAO-B) inhibitors. Many patients with PD also exhibit memory loss in the later stages of disease progression, which is treated with acetylcholine esterase (AChE) inhibitors. We sought to identify a dual-mechanism compound that would inhibit both MAO-B and AChE enzymes. Our screen identified a promising compound (7) with balanced MAO-B (IC 50 of 16.83 μM) and AChE inhibition activity (AChE IC 50 of 22.04 μM). Application of this compound 7 increased short-term associative memory and significantly prevented 6-hydroxy-dopamine toxicity in dopaminergic neurons in the Caenorhabditis elegans nematode. These findings present a platform for future development of dual-mechanism drugs to treat neurodegenerative diseases such as PD.
