9-ME-BC CAS 2521-07-5
9-Methyl-β-Carboline — Monoamine Oxidase Inhibitor
9-ME-BC (CAS 2521-07-5), or 9-methyl-β-carboline, is a naturally inspired β-carboline alkaloid that inhibits monoamine oxidase (MAO-A/MAO-B), raises monoamine tone (dopamine, serotonin, norepinephrine) and limits formation of the neurotoxic MPP+ metabolite. It is widely studied for neuroprotection, dopaminergic survival and cognitive neuroscience. Formula C12H10N2, MW 182.22. Research-grade with COA.

Key Molecular Targets & Pathway Nodes
9-ME-BC (9-Methyl-β-Carboline) engages the molecular machinery and pathway nodes that define its research utility.
How 9-ME-BC Works: Protecting Monoamine Signaling
9-ME-BC blocks monoamine oxidase and curbs the cascade that destroys dopaminergic neurons
MAO-A / MAO-B Catalytic Inhibition
9-ME-BC is a β-carboline that inhibits monoamine oxidase enzymes, particularly MAO-A, slowing the oxidative deamination of dopamine, serotonin and norepinephrine. This raises synaptic and intracellular monoamine availability.
Blockade of Neurotoxic MPP+ Formation
By limiting MAO-B-driven oxidation of MPTP-like substrates, 9-ME-BC reduces formation of the mitochondrial toxin MPP+ (1-methyl-4-phenylpyridinium), a key driver of dopaminergic neuron death in Parkinson's models.
Neuroprotection, Survival & Cognitive Tone
Elevated monoamines support dopaminergic neuron survival, neurite outgrowth and synaptic plasticity. The net research phenotype is neuroprotection, improved monoamine tone and resilience to oxidative / excitotoxic stress.
