|Section2= |Section3= }} Pyrazolopyrimidines are a series of isomeric heterocyclic chemical compounds with the molecular formula C6H5N3. They form the central core of a variety of more complex chemical compounds including some pharmaceuticals and pesticides. ==Pharmaceuticals== One isomer of pyrazolopyrimidines, known as pyrazolo()pyrimidine, is the basis for a class of sedative and anxiolytic drugs related (in terms of their effect) to benzodiazepines. Most of the drugs from this class marketed to date are intended to induce sleep, and are prescribed for people suffering insomnia, however some newer compounds produce anxiolytic effects with relatively little sedation, and are being developed for use as non-sedating anti-anxiety drugs. They include: * Zaleplon - hypnotic (trade name Sonata) * Indiplon - hypnotic * Ocinaplon - anxiolytic * Divaplon - anxiolytic * Lorediplon - hypnotic As they are not chemically related to the benzodiazepines despite their similar effect, such drugs—as well as the imidazopyridines and cyclopyrrones—are sometimes grouped together and referred to as "nonbenzodiazepines". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「pyrazolopyrimidine」の詳細全文を読む スポンサード リンク
