Zaleplon

Description

Zaleplon, also known as sonata or dea no. 2781, belongs to the class of organic compounds known as phenylpyrimidines. These are polycyclic aromatic compounds containing a benzene ring linked to a pyrimidine ring through a CC or CN bond. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Zaleplon is a drug which is used for the treatment of short-term treatment of insomnia in adults. Zaleplon is an extremely weak basic (essentially neutral) compound (based on its pKa). Zaleplon is a potentially toxic compound. A pyrazolopyrimidine having a nitrile group at position 3 and a 3-(N-ethylacetamido)phenyl substituent at the 7-position.

Enzyme Details

2. 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
