Apigenin

5,7-Dihydroxy-2-(4-hydroxyphenyl)-4H-1-benzopyran-4-one

C15H10O5 (270.0528)


Apigenin is a trihydroxyflavone that is flavone substituted by hydroxy groups at positions 4, 5 and 7. It induces autophagy in leukaemia cells. It has a role as a metabolite and an antineoplastic agent. It is a conjugate acid of an apigenin-7-olate. Apigenin is a natural product found in Verbascum lychnitis, Carex fraseriana, and other organisms with data available. Apigenin is a plant-derived flavonoid that has significant promise as a skin cancer chemopreventive agent. Apigenin inhibits the expression of involucrin (hINV), a marker of keratinocyte differentiation, is increased by differentiating agents via a protein kinase Cdelta (PKCdelta), Ras, MEKK1, MEK3 cascade that increases AP1 factor level and AP1 factor binding to DNA elements in the hINV promoter. Apigenin suppresses the 12-O-tetradeconylphorbol-13-acetate-dependent increase in AP1 factor expression and binding to the hINV promoter and the increase in hINV promoter activity. Apigenin also inhibits the increase in promoter activity observed following overexpression of PKCdelta, constitutively active Ras, or MEKK1. The suppression of PKCdelta activity is associated with reduced phosphorylation of PKCdelta-Y311. Activation of hINV promoter activity by the green tea polyphenol, (-)-epigellocathecin-3-gallate, is also inhibited by apigenin, suggesting that the two chemopreventive agents can produce opposing actions in keratinocytes. (A7924). Apigenin, a flavone abundantly found in fruits and vegetables, exhibits antiproliferative, anti-inflammatory, and antimetastatic activities through poorly defined mechanisms. This flavonoid provides selective activity to promote caspase-dependent-apoptosis of leukemia cells and uncover an essential role of PKCdelta during the induction of apoptosis by apigenin. (A7925). Apigenin markedly induces the expression of death receptor 5 (DR5) and synergistically acts with exogenous soluble recombinant human tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) to induce apoptosis in malignant tumor cells. On the other hand, apigenin-mediated induction of DR5 expression is not observed in normal human peripheral blood mononuclear cells. Moreover, apigenin does not sensitize normal human peripheral blood mononuclear cells to TRAIL-induced apoptosis. (A7926). 5,7,4-trihydroxy-flavone, one of the FLAVONES.

Cirsimaritin

5-Hydroxy-2-(4-hydroxyphenyl)-6,7-dimethoxy-4H-chromen-4-one

C17H14O6 (314.079)


Cirsimaritin, also known as 4,5-dihydroxy-6,7-dimethoxyflavone or scrophulein, is a member of the class of compounds known as 7-o-methylated flavonoids. 7-o-methylated flavonoids are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, cirsimaritin is considered to be a flavonoid lipid molecule. Cirsimaritin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Cirsimaritin can be found in a number of food items such as italian oregano, lemon verbena, winter savory, and rosemary, which makes cirsimaritin a potential biomarker for the consumption of these food products.
