| | chrysosplenetin B Usage And Synthesis |
| Occurance | Chrysosplenetin B is a tetramethoxyflavone that is the 3,6,7,3'-tetramethyl ether derivative of quercetagetin. It has a role as an antiviral agent and a plant metabolite. It is a tetramethoxyflavone and a dihydroxyflavone. It derives from a quercetagetin.
Chrysosplenetin B is an O-methylated flavonol. It can be found in the root of Berneuxia thibetica and in Chamomilla recutita.
| | Chemical Properties | Yellow crystalline powder, soluble in organic solvents such as methanol, ethanol, and DMSO, derived from Laggera pterodonta. | | Uses | Chrysosplenetin is one of the polymethoxylated flavonoids in Artemisia annua L. (Compositae) and other several Chinese herbs. Chrysosplenetin inhibits P-gp activity and reverses the up-regulated P-gp and MDR1 levels induced by artemisinin (ART). Chrysosplenetin significantly augments the rat plasma level and anti-malarial efficacy of ART, partially due to the uncompetitive inhibition effect of Chrysosplenetin on rat CYP3A[1]. | | Definition | ChEBI: A tetramethoxyflavone that is the 3,6,7,3'-tetramethyl ether derivative of quercetagetin. | | IC 50 | CYP3A | | References | [1] Ma L, et al.
