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].

Name	Guan-fu base G

Description	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].
Target	IC50: 17.9 μM (HERG channel)[2]
In Vitro	The effects of Guanfu base G is investigated in human embryonic kidney 293 (HEK293) cells transiently transfected with HERG complementary DNA using a whole-cell patch clamp technique. Guanfu base G inhibits HERG channel current in concentration-, voltage-, and time-dependent manners. Guanfu base G shifts the activation curve in a negative direction and accelerated channel inactivation but shows no effect on the inactivation curve. Moreover, Guanfu base G also accelerates channel recovery from inactivation[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]. Animal Model: Rats[1] Dosage: 5 mg/kg Administration: Intravenous injection; for 5, 15, 30, 45, 60, 120, 240, 360, 480, 600, 720, 960 and 1200 minutes (Pharmacokinetic study) Result: The pharmacokinetic behavior was better in rats, the T1/2 was 4.16 hours.
