Baicalin, aka 3,4,5-trihydroxyflavone 4O-glycoside, is a naturally-occurring phenolic flavone isolated from the plant Scutellaria baicalensis. It is a glycoside prodrug for baicalein and can metabolize into baicalein and glucose. It is significantly less bioavailable than baicalein and is therefore less active as a GABAergic positive allosteric modulator. Various flavone derivatives appear to display similar in vitro binding affinity to benzodiazepenes at the BZD-specific GABAnergic binding sites. This results in the increase of ionic current caused by chloride flow from the ligand gated channels. Because it readily metabolizes into baicalein, baicalin is expected to have virtually identical pharmacophore, albeit with reduced potency. Like baicalein, baicalin can slow the metabolism of other drugs via inhibition of the CYP450 enzymes commonly found in hepatocytes in the human liver (which are responsible for the large majority of metabolic routes for drugs in the human body).
