General description

Apigenin is a 270 Da flavonoid, which belongs to the flavone group of glycosides. It is synthesized by a wide variety of plants including cereals, grains, tea and oranges.

Application

Apigenin has been used as a calibration standard for the quantification of Hieracium pannosum Boiss, Juniperus sp, using high-performance liquid chromatography (HPLC) with Diode-Array Detection (DAD). It has been used to study effect on hormone secretion in the human adrenocortical H295R cells.

Biochem/physiol Actions

A plant flavonoid that has been found to inhibit cell proliferation by arresting the cell cycle at the G2/M phase. Inhibition of growth through cell cycle arrest and induction of apoptosis appear to be related to induction of p53. Inhibits PMA-mediated tumor promotion by inhibiting protein kinase C and the resulting suppression of oncogene expression. It has also been reported to inhibit topoisomerase I-catalyzed DNA re-ligation and enhance gap junctional intercellular communication.
Apigenin is a class II pharmaceutical drug and highly intestine permeable. It has antioxidant, anti-inflammatory and antitumorigenic functionality. It is a potent inhibitor of the cluster of differentiation 38 (CD30) nucleotide adenine dinucleotide (NAD+) nucleosidase and could be used to suppress CD30 mediated metabolic syndrome.
