Kaempferide is an O-methylated flavonol, a type of chemical compound. It can be found in Kaempferia galanga (aromatic ginger). It has been noted to inhibit pancreatic cancer growth by blockading an EGFR-related pathway.[1]
The enzyme kaempferol 4'-O-methyltransferase uses S-adenosyl-L-methionine and kaempferol to produce S-adenosyl-L-homocysteine and kaempferide.
Glycosides
