Chemical Properties
White crystals, soluble in organic solvents such as methanol, ethanol, DMSO, etc., derived from the tuberous root of Aconitum carmichaelii (Kanbaifu), a plant of the Ranunculaceae family.
Uses
Guanfu base G is an antiarrhythmic alkaloid isolated from Aconitum coreanum. Guanfu base G inhibits HERG channel current with an IC50 of 17.9 μM[1][2].
in vivo
Guanfu base G (5 mg/kg; intravenous injection; for 5-1200 minutes; rats) treatment in rats after 15 min could be detected the presence of Guanfu base A, about 10% of Guanfu base G in vivo could metabolize to Guanfu base A, which may be related to the metabolic enzymes in the body and its nature-related compounds, however, the substance in the body to eliminate more quickly, could be detected only around 240 min. The pharmacokinetic behavior of Guanfu base G is better in rats, the T1/2 is 4.16 hours. These results indicate that Guanfu base G has a relatively suitable elimination half-life[1].
