Documented Uses

• Experimental drug ... lipid kinase activity
• ... Significant quantities of quercetin and possibly myricetin and kaempferol are absorbed in the gut. A larger fraction probably remains in the lumen, and thus a substantial proportion of the gastrointestinal mucosa is exposed to biologically significant concentrations of these compounds. ...
• Myricetin has known human metabolites that include (2S,3S,4S,5R)-6-[5,7-Dihydroxy-4-oxo-2-(3,4,5-trihydroxyphenyl)chromen-3-yl]oxy-3,4,5-trihydroxyoxane-2-carboxylic acid.
