Roles Classification
Biological Role(s): drug metabolite

human blood serum metabolite
Any metabolite (endogenous or exogenous) found in human blood serum samples.
human urinary metabolite
Any metabolite (endogenous or exogenous) found in human urine samples.
GABA modulator
A substance that does not act as agonist or antagonist but does affect the gamma-aminobutyric acid receptor-ionophore complex. GABA-A receptors appear to have at least three allosteric sites at which modulators act: a site at which benzodiazepines act by increasing the opening frequency of gamma-aminobutyric acid-activated chloride channels; a site at which barbiturates act to prolong the duration of channel opening; and a site at which some steroids may act.
