Pyrazolopyrimidines are a series of isomericheterocyclicchemical compounds with the molecular formula C6H5N3. [1] 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[1,5-a]pyrimidine, is the basis for a class of sedative and anxiolyticdrugs 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.
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".
