dopamine catabolic process

Definition

Target type: biologicalprocess

The chemical reactions and pathways resulting in the breakdown of dopamine, a catecholamine neurotransmitter and a metabolic precursor of noradrenaline and adrenaline. [GOC:jl, ISBN:0198506732]

Dopamine catabolism is the enzymatic breakdown of dopamine, a neurotransmitter, into inactive metabolites. This process is essential for regulating dopamine levels in the brain and maintaining normal brain function.

The primary enzyme involved in dopamine catabolism is monoamine oxidase (MAO), specifically MAO-B. MAO-B is located on the outer mitochondrial membrane of neurons and glial cells. It catalyzes the oxidative deamination of dopamine, converting it to 3,4-dihydroxyphenylacetaldehyde (DOPAL).

DOPAL is then further metabolized by aldehyde dehydrogenase (ALDH) into 3,4-dihydroxyphenylacetic acid (DOPAC), the major dopamine metabolite in the brain. DOPAC can be further metabolized by catechol-O-methyltransferase (COMT) into homovanillic acid (HVA), which is excreted in urine.

Dopamine catabolism is tightly regulated, and dysregulation of this process can contribute to various neurological disorders. For example, excessive dopamine catabolism can lead to dopamine depletion and contribute to Parkinson's disease. Conversely, reduced dopamine catabolism can lead to dopamine accumulation and contribute to conditions like schizophrenia.

In addition to MAO-B, other enzymes can contribute to dopamine catabolism to a lesser extent. These include:

* **Catechol-O-methyltransferase (COMT):** COMT catalyzes the methylation of dopamine, converting it to 3-methoxytyramine (3-MT).
* **Alcohol dehydrogenase (ADH):** ADH can convert DOPAL to DOPAC, although this pathway is less significant than ALDH.

Dopamine catabolism is a complex and tightly regulated process that is crucial for maintaining normal dopamine levels in the brain. Dysregulation of this process can have significant implications for brain health and function.'

clozapineclozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11. It is a second generation antipsychotic used in the treatment of psychiatric disorders like schizophrenia.

Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.
