Parkinson's disease (PD) is associated with elevated levels of hMAO-B in the brain, and MAO-B has been recognized a successful target for developing anti-PD drugs. Herein we report rasagiline derivatives as novel potent and selective hMAO-B inhibitors. They were designed by employing fragment-based drug design strategy to link rasagiline and hydrophobic fragments, which may target a hydrophobic pocket in the entrance cavity of hMAO-B. Different linkers such as -OCH2-, -SCH2-, -OCH2CH2-, -OCH2CH2O-, -OCH2CH2CH2O- were tried. A promising selective hMAO-B inhibitor D14 with similar inhibitory activity as rasagiline and improved isoform selectivity was yielded. The selectivity profile of compounds reported herein suggests that we can further develop more potent hMAO-B inhibitors with high isoform selectivity through this strategy.

UI MeSH Term Description Entries
D007189 Indans Aryl CYCLOPENTANES that are a reduced (protonated) form of INDENES. Indanones
D007192 Indenes A family of fused-ring hydrocarbons isolated from coal tar that act as intermediates in various chemical reactions and are used in the production of coumarone-indene resins.
D008958 Models, Molecular Models used experimentally or theoretically to study molecular shape, electronic properties, or interactions; includes analogous molecules, computer-generated graphics, and mechanical structures. Molecular Models,Model, Molecular,Molecular Model
D008995 Monoamine Oxidase An enzyme that catalyzes the oxidative deamination of naturally occurring monoamines. It is a flavin-containing enzyme that is localized in mitochondrial membranes, whether in nerve terminals, the liver, or other organs. Monoamine oxidase is important in regulating the metabolic degradation of catecholamines and serotonin in neural or target tissues. Hepatic monoamine oxidase has a crucial defensive role in inactivating circulating monoamines or those, such as tyramine, that originate in the gut and are absorbed into the portal circulation.
