Monoamine oxidase (MAO) is crucial for regulating brain activity and is implicated in neurodegenerative and depressive disorders. MAO inhibitors are being re-evaluated for treating conditions like Parkinson's and Alzheimer's disease.
Area of Science:
- Biochemistry and Pharmacology
- Neuroscience
Context:
- Monoamine oxidase (MAO) is an enzyme in the outer mitochondrial membrane involved in neurotransmitter and hormone metabolism.
- MAO substrates include neurotransmitters (serotonin, dopamine), hormones, and neurotoxins like MPTP, linking MAO to central nervous system regulation.
- MAO plays a role in the pathogenesis of neurodegenerative and depressive disorders.
Purpose:
- To provide an overview of the physiological importance of Monoamine oxidase (MAO).
- To discuss the biochemical and pharmacological potential of MAO inhibitors.
- To consider the therapeutic applications of MAO inhibitors in human disorders.
Summary:
- MAO, an enzyme catalyzing monoamine oxidative deamination, is vital for regulating neurotransmitters and hormones.
- First-generation MAO inhibitors had therapeutic use but significant side effects.
- Recent interest in MAO and its inhibitors offers new therapeutic avenues for Parkinson's, Alzheimer's, and depression, with ongoing research for safer compounds.
Impact:
- MAO inhibitors are gaining renewed attention for treating neurological and psychiatric conditions.
- The search for novel MAO inhibitors with improved safety profiles is a key area of pharmacological research.
- Understanding MAO's role is critical for developing effective treatments for central nervous system disorders.

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
