ARTEMISININ Usage And Synthesis

Chemical Properties

Yellow powder

Uses

Kaempferide is a flavonoid that maintains anti-radical and anti-oxidant capabilities, as well as anti-tumour possibilities. Impurity of Icaritin (I163700).

Definition

ChEBI: A monomethoxyflavone that is the 4'-O-methyl derivative of kaempferol.

Biological Activity

the effects of phytoestrogens have been studied in the hypothalamic-pituitary-gonadal axis and various non-gonadal targets. epidemiologic and experimental evidence indicates a protective effect of phytoestrogens also in colorectal cancer. the mechanism through which estrogenic molecules control colorectal cancer tumorigenesis could possibly involve estrogen receptor β, which is the predominantly expressed estrogen receptor subtype in colon mucosa.

in vitro

kaempferide triglycoside proved to inhibit the proliferation of native and estrogen receptor β overexpressing colon cancer cells via a mechanism not mediated by ligand binding dependent estrogen receptor activation. it affected hct8 cell cycle progression through increasing the g0/g1 cell fraction and in estrogen receptor β overexpressing cells increased two antioxidant enzymes [1].

in vivo

the aim of one previous study was to evaluate the effect of kaempferol on tissue lipid peroxidation and antioxidant status in 1,2-dimethyl hydrazine induced colorectal cancer in male wistar rats and to compare its efficacy with irinotecan. this study revealed that kaempferol could be safely used as a chemopreventive agent in colorectal cancer [2].
