Clonazepam

Description

Clonazepam, also known as klonopin or rivotril, belongs to the class of organic compounds known as 1,4-benzodiazepines. These are organic compounds containing a benzene ring fused to a 1,4-azepine. It is used in the treatment of all types of epilepsy and seizures, as well as myoclonus and associated abnormal movements, and panic disorders. Clonazepam is a moderately basic compound (based on its pKa). Clonazepam is a potentially toxic compound. 1,3-Dihydro-2H-1,4-benzodiazepin-2-one in which the hydrogens at positions 5 and 7 are substituted by 2-chlorophenyl and nitro groups, respectively. However, its use can be limited by the development of tolerance and by sedation.

Enzymes

Enzyme Details

1. Cytochrome P450 3A4

General function:: Involved in monooxygenase activity
Specific function:: Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.

2. Gamma-aminobutyric acid receptor subunit gamma-2

General function:: Involved in ion transport
Specific function:: GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel
Gene Name:: GABRG2
Uniprot ID:: P18507
Molecular weight:: 54161.8

Enzyme Details

3. Translocator protein

General function:: Signal transduction mechanisms
Specific function:: Responsible for the manifestation of peripheral-type benzodiazepine recognition sites and is most likely to comprise binding domains for benzodiazepines and isoquinoline carboxamides. May play a role in the transport of porphyrins and heme. Plays a role in the transport of cholesterol across mitochondrial membranes in steroidogenic cells
