dc.description.abstractParkinson’s disease is characterised by the death of the nigrostriatal neurons and depletion of striatal dopamine. The standard symptomatic therapy consists of dopamine replacement with l-dopa, the metabolic precursor of dopamine, which represents the most effective treatment. Since monoamine oxidase (MAO) B is a key dopamine metabolising enzyme in the brain, MAO-B inhibitors are often used as adjuvants to l-dopa. In addition to the symptomatic benefits offered by MAO-B inhibitors, these drugs may also possess neuroprotective properties and possibly delay the progression of Parkinson’s disease. Based on the therapeutic use of MAO-B inhibitors, the present study evaluates a series of mono- and disubstituted derivatives of 4(3H)-quinazolinone as potential inhibitors of recombinant human MAO-A and MAO-B. Twelve C6-monosubstituted and nine N3/C6-disubstituted 4(3H)-quinazolinone derivatives were synthesised, which led to the discovery of novel quinazolinone derivatives with micromolar and submicromolar activities as inhibitors of MAO-B. The most potent mono- and disubstituted derivatives exhibited IC50 values of 6.35 μM (7f) and 0.685 μM (8b), respectively. This study identifies suitable substitution patterns for the design of 4(3H)-quinazolinone derivatives as MAO-B inhibitorsen_US
