Biological Activity

Description Apigenin is a potent P450 inhibitor for CYP2C9 with Ki of 2 μM.
Features Much more potent than kaempferol and myricetin in CT-L inhibition.
Targets
CYP2C9 [5]
2 μM(Ki)
In vitro
In vitro 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. [1] 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. [2] Apigenin inhibits differentiation by suppressing MAPK signal transduction and reducing API transcription factor level in human keratinocytes. Apigenin also inhibits proliferating of human keratinocytes. [3]
Cell Research Cell lines WI-38, T-24, HT-1376 and PC-3 cells
Concentrations 0, 1, 5, 10, 20, 30, 40, and 50 μg/ml
Incubation Time 24 h
Method

To measure the effect of apigenin on cell viability, the WI-38, T-24, HT-1376 and PC-3 cells were seeded in 24-well plates (1 × 105 cells/well) for 16-18 h. The cells were then treated with or without various concentrations (0, 1, 5, 10, 20, 30, 40, and 50 μg/ml) of apigenin for 24 h. Each treatment was repeated 3 times. After the exposure period, the medium was removed and followed by washing the cells with PBS. The medium was then changed and incubated with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) solution (5 mg/ml)/well for 4 h. The medium was removed, and formazan was solubilised in isopropanol and measured spectrophotometrically at 563 nm. The percentage of viable cells was estimated by comparing them with the untreated control cells.

In Vivo
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. [2] Apigenin (12.5 mg/kg) increases cell proliferation in the dentate gyrus of hippocampus of adult mice. [4]
