product name Apigenin
Description: Apigenin, is a potent P450 inhibitor for CYP2C9 with Ki of 2 μM. Apigenin is a natural flavonoid product found in many plants and belongs to the flavone class that is the aglycone of several naturally occurring glycosides. Apigenin is an antioxidant plant flavanoid which contains anti-inflammatory and anticancer properties. It may induce apoptosis and may inhibit proliferation of tumor cells by arresting the cell cycle at the G2/M phase.

In vitro activity: Apigenin inhibits PKC by competing with adenosine triphosphate (ATP). Apigenin also reduces the level of TPA-stimulated phosphorylation of cellular proteins and inhibits TPA-induced c-jun and c-fos expression. Apigenin exhibits the reverting effect on the transformed morphology of v-H-ras transformed NIH3T3 cells. Apigenin has been shown to possess anti-mutagenic properties in a setting of nitropyrene-induced genotoxicity in Chinese hamster ovary cells. Apigenin suppresses of LPS-induced cyclooxygenase-2 and nitric oxide synthase-2 activity and expression in mouse macrophages. Apigenin has been reported to inhibit protein kinase C activity, mitogen-activated protein kinase (MAPK), transformation of C3HI mouse embryonic fibroblasts and downstream oncogenes in v-Ha-ras-transformed NIH3T3 cells. Apigenin blocks peroxisome proliferation-regulated kinase (ERK), a MAPK in isolated hepatocytes. Apigenin has further been shown to down-regulate the expression of the Na+/Ca2+-exchanger, a protein important for calcium extrusion in neonatal rat cardiac myocytes. Apigenin induces a reversible G2/M and G0/G1 arrest by inhibiting p34 (cdc2) kinase activity, accompanied by increased p53 protein stability in epidermal cells and fibroblasts. Apigenin is also effective in inhibiting TNFα-induced intracellular adhesion molecule-1 upregulation in cultured human endothelial cells. Apigenin inhibits the expression of HIF-1α and VEGF via the PI3K/Akt/p70S6K1 and HDM2/p53 pathways in human ovarian cancer cells. Apigenin inhibits differentiation by suppressing MAPK signal transduction and reducing API transcription factor level in human keratinocytes. Apigenin also inhibits proliferating of human keratinocytes. Kinase Assay: Cell Assay: |

| In Vivo | Apigenin down-regulates production of IL-4 in ovalbumin-immunized BALB/C mice. Apigenin inhibits melanoma lung metastases by impairing interaction of tumor cells with endothelium. Apigenin is shown to cause a significant increase in uterine weight and overall uterine concentration of estrogen receptor (ER)-α in female mice (64) and also suppresses prostate and breast cancer cell growth through estrogen receptor β1. Apigenin suppresses the levels of IGF-I in prostate tumor xenografts and increases levels of IGFBP-3, a binding protein that sequesters IGF-I in vascular circulation. Apigenin (12.5 mg/kg) increases cell proliferation in the dentate gyrus of hippocampus of adult mice. |
