The biosynthesis of flavones proceeds from the phenylpropanoid pathway, which uses L-phenylalanine as a starting point. Phenylalanine ammonia lyase facilitates the deamination of L-phenylalanine to (E)-cinnamate, which is then oxidized by cinnamate 4-hydroxylase to yield p-Coumaric acid. Coenzyme A is attached to the carboxylate facilitated by 4-Coumarate-CoA ligase, forming (Co… WebDec 14, 2024 · Flavone has recently been proved as a promising scaffold for the development of a novel drug against dengue fever, one of the major health threats globally. However, the structure–activity relationship study of flavones on the anti-dengue activity remains mostly limited to the natural-occuring analogs.
