| Targets |
MAO-B-IN-9 targets monoamine oxidase B (MAO-B), a flavoenzyme located on the outer mitochondrial membrane that catalyzes the oxidative deamination of biogenic amines. MAO-B is primarily involved in the metabolism of dopamine and other neurotransmitters. Inhibition of MAO-B increases dopamine levels in the brain and is a therapeutic strategy for neurodegenerative diseases such as Parkinson's disease. The compound has an IC50 of 0.18 μM for MAO-B and is selective, irreversible, and time-dependent. It is BBB-permeable, making it suitable for CNS applications.

| ln Vitro |
In vitro, MAO-B-IN-9 inhibits MAO-B with an IC50 of 0.18 μM. It is selective for MAO-B over MAO-A. The compound prevents Aβ1-42-induced neuronal cell death, demonstrating neuroprotective effects. Its neuroprotective mechanism may involve anti-aggregation effects on Aβ1-42, preventing the formation of toxic amyloid aggregates. The compound is irreversible and time-dependent in its inhibition of MAO-B.
|
| ln Vivo |
In vivo, MAO-B-IN-9 is expected to show neuroprotective effects in animal models of neurodegenerative diseases. Its ability to prevent Aβ1-42-induced neuronal cell death suggests potential applications in Alzheimer's disease research. The compound's BBB permeability makes it suitable for central nervous system studies. However, specific in vivo efficacy data for this compound are not extensively reported in the available literature.
|
| Enzyme Assay |
In vitro enzyme/receptor binding assays for MAO-B-IN-9 typically involve MAO-B activity assays using purified recombinant MAO-B enzyme or rat brain mitochondrial fractions. The assay is performed in 96-well plates with assay buffer (50 mM potassium phosphate pH 7.4). The compound (typically 0.001-100 μM) is pre-incubated with the enzyme for 30 minutes before adding the substrate (e.g., kynuramine or benzylamine). MAO-B activity is measured by fluorescence detection of the oxidation product (4-hydroxyquinoline for kynuramine, excitation 310 nm, emission 400 nm). The IC50 is determined from dose-response curves.
|
| Cell Assay |
In vitro cellular assays for MAO-B-IN-9 use neuronal cell lines such as SH-SY5Y or primary cortical neurons. Cells are cultured in DMEM/F12 with 10% FBS and treated with various concentrations of the compound (typically 0.01-10 μM) for 4-24 hours. Neuroprotection is assessed by exposing cells to Aβ1-42 peptide (10 μM) for 24-48 hours and measuring cell viability using MTT or LDH assays. Neurite outgrowth and synaptic markers can be assessed by immunocytochemistry. MAO-B activity in cell lysates is measured using a fluorometric assay.
|
| Animal Protocol |
In vivo animal studies with MAO-B-IN-9 would typically use mouse models of Alzheimer's disease or Parkinson's disease. In Aβ injection models, mice are injected intracerebroventricularly with Aβ1-42 and treated with the compound orally or intraperitoneally at doses of 1-30 mg/kg daily for 7-14 days. Cognitive function is assessed by Morris water maze or Y-maze tests. Brain tissue is analyzed for Aβ aggregation, oxidative stress markers, and neurodegeneration. In MPTP-induced Parkinson's disease models, dopamine neuron survival is assessed.
