Description

Pentobarbital, also known as nembutal or pentobarbitone, belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Pentobarbital is a drug which is used for the short-term treatment of insomnia. Based on a literature review a significant number of articles have been published on Pentobarbital.

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.
Gene Name:: CYP3A4
Uniprot ID:: P08684
Molecular weight:: 57255.585

Enzyme Details

2. Cytochrome P450 2C19

General function:: Involved in monooxygenase activity
Specific function:: Responsible for the metabolism of a number of therapeutic agents such as the anticonvulsant drug S-mephenytoin, omeprazole, proguanil, certain barbiturates, diazepam, propranolol, citalopram and imipramine.
Gene Name:: CYP2C19
Uniprot ID:: P33261
Molecular weight:: 55944.565

Enzyme Details

3. Glutamate receptor, ionotropic kainate 2

General function:: Involved in ionotropic glutamate receptor activity
Specific function:: Ionotropic glutamate receptor. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. Binding of the excitatory neurotransmitter L- glutamate induces a conformation change, leading to the opening of the cation channel, and thereby converts the chemical signal to an electrical impulse. The receptor then desensitizes rapidly and enters a transient inactive state, characterized by the presence of bound agonist. May be involved in the transmission of light information from the retina to the hypothalamus. Modulates cell surface expression of NETO2
