Metabolite Identification
Common NameBenzquinamide
DescriptionBenzquinamide, also known as benzchinamid or BZQ, belongs to the class of organic compounds known as tetrahydroisoquinolines. These are tetrahydrogenated isoquinoline derivatives. Benzquinamide is a drug which is used to prevent and treat nausea and vomiting associated with anesthesia and surgery, administered intramuscularly or intravenously. Benzquinamide is a discontinued antiemetic drug used in post-operative care. Benzquinamide is a very strong basic compound (based on its pKa). Benzquinamide is a potentially toxic compound.

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
In peripheral tissues, the H1 subclass of histamine receptors mediates the contraction of smooth muscles, increase in capillary permeability due to contraction of terminal venules, and catecholamine release from adrenal medulla, as well as mediating neurotransmission in the central nervous system
