Metabolite Identification
Common Namedesethylzaleplon
Descriptiondesethylzaleplon is a metabolite of zaleplon. Zaleplon (marketed under the brand names Sonata and Starnoc) is a sedative/hypnotic, mainly used for insomnia. It is a nonbenzodiazepine hypnotic from the pyrazolopyrimidine class. In terms of adverse effects zaleplon appears to offer little improvement compared to both benzodiazepines and other non-benzodiazepine Z-drugs. Sonata (US) is manufactured by King Pharm. of Bristol, TN; Starnoc has been discontinued in Canada. (Wikipedia)

Chemical Taxonomy
Description 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.
