Unlock the secret of 9-methyl-β-carboline, a chemical compound that has been making waves in the world of cognitive enhancement and brain health!

This remarkable substance, also known as 9-Me-BC, has shown its ability to stimulate dopamine activity, increase dopamine levels, and provide a myriad of potential cognitive benefits.

In this comprehensive review, we will delve into 9-Me-BC’s restorative effects, its impact on dopamine synthesis, and its neuroprotective properties.

Read on to learn everything you need to know about 9-Me-BC.

What is 9-Me-BC?

9-Me-BC (also known as 9-MBC, 9-methyl-β-carboline, 9-Methylnorharman, and N-Methyl-β-carboline) is a new chemical compound that has gained attention for its nootropic and neuroprotective properties.

9-Me-BC is derived from its family of β-carboline class of compounds and is an intriguing heterocyclic amine that has caught our attention. It has protective effects on the central nervous system and has a particularly potent impact on dopamine activity and neuroinflammation.

How does it impact this vital neurotransmitter?

9-Me-BC can stimulate dopamine activity and increase its consistency in the brain. Dopamine is a neurotransmitter associated with mood regulation, motivation, reward, and cognitive function.

9-Me-BC also has neuroprotective properties, meaning it protects neurons, particularly central dopaminergic neurons, from damage or degeneration. This makes it of interest in the context of neurodegenerative diseases like Alzheimer’s and Parkinson’s disease.(1)

Additionally, 9-Me-BC may prevent cognitive decline. This nootropic compound creates an anti-inflammatory environment in the central nervous system (CNS). This anti-inflammatory action is beneficial in reducing neuroinflammation, which is often associated with various neurological conditions.

Overall, due to its potential to increase dopamine levels and its impact on brain function, 9-Me-BC has garnered a significant amount of hype as a cognitive enhancer.


  • Enhances focus, mental stamina, and cognitive function
  • Stimulates dopamine activity in the brain
  • Neuroprotective properties for dopaminergic neurons
  • Create an anti-inflammatory environment in the CNS


  • The long-term effects of 9-Me-BC on human health are not well understood
  • Not approved by the FDA (Food and Drug Administration)

Mechanism of Action

The exact mechanism of action of 9-Me-BC (9-methyl-β-carboline) is not fully understood, and research in this area is ongoing.

However, based on available studies and findings, here are some potential mechanisms by which 9-Me-BC may exert its effects:

  1. MOA Inhibitor: MAO is an enzyme responsible for breaking down these neurotransmitters, and inhibiting MAO can lead to increased levels of monoamines in the brain. This, in turn, has effects on mood, cognition, and other aspects of brain function. By inhibiting MAO, 9-Me-BC contributes to its potential cognitive-enhancing and mood-regulating properties.
  2. Dopamine Stimulation: One of the primary mechanisms associated with 9-Me-BC is its ability to stimulate dopamine activity. Dopamine is a neurotransmitter that plays a crucial role in mood regulation, motivation, reward, and cognitive function. By increasing dopamine activity or availability, 9-Me-BC may enhance these aspects of brain function.
  3. Neuroprotection for Central Dopaminergic Neurons: Research suggests that 9-Me-BC may have neuroprotective properties, particularly for dopaminergic neurons.(2) It may help protect these neurons from damage or degeneration, making it of interest in neurodegenerative diseases like Parkinson’s disease. The exact mechanisms of this neuroprotection are still being investigated.
  4. Anti-Inflammatory Effects: 9-Me-BC has been associated with creating an anti-inflammatory environment in the central nervous system (CNS). This anti-inflammatory action could be beneficial in reducing neuroinflammation, which is often implicated in various neurological conditions. The precise molecular mechanisms involved in this anti-inflammatory effect require further exploration.
  5. Modulation of Neurotransmitter Systems: 9-Me-BC may modulate other neurotransmitter systems beyond dopamine, such as serotonin and other monoamines.(3) This modulation could contribute to its effects on mood and cognition.
  6. Neurotrophic Effects: Some studies suggest that 9-Me-BC may promote the growth and proliferation of neurons through increasing synapses and ATP levels in the brain, potentially contributing to its neuroprotective and regenerative effects.(4) This could involve the activation of signaling pathways related to neuronal growth and differentiation.
