General description

Kaempferol is a natural dietary flavonoid and a polyphenol antioxidant found in various fruits and vegetables. Kaempferol is present in plants in a different glycosidic form such as astragalin by binding with different sugars.

Application

Kaempferol (KAE) has been used:
  • to check its potential effect as an antioxidant and neuroprotective agent against rotenone-induced Parkinson′s disease (PD) model in SH-S5Y5 cells
  • to test its anti-inflammatory effect on lipopolysaccharide (LPS)-induced inflammatory injury in human aortic endothelial cells (HAECs)
  • to study its apoptosis sensitizing effect on non-small cell lung cancer (NSCLC) cells by inhibiting nuclear factor erythroid 2-related factor 2 (Nrf2)

Chromogenic reagent for antimony in the low ppm range and for gallium and indium in the sub-ppm range.

Biochem/physiol Actions

Potent inhibitor of osteoclastic bone resorption. The effect is believed to be attributable to both the antioxidant and estrogenic activities of kaempferol.
The diphenylpropane component of Kaempferol contributes to its hydrophobic properties. It has shown to revert the transformed phenotype of phorbol ester-treated mouse fibroblasts or v-H-ras-transformed NIH 3T3 cells. Kaempferol induces significant nuclear DNA degradation concurrent with lipid peroxidation. It also inhibits topoisomerase I catalyzed DNA religation. Kaempferol may also inhibit the activity of fatty acid synthase.

Packaging

The extent of DNA damage and lipid peroxidation induced by kaempferol, a polyphenolic flavonoid with a molecular structure similar to quercetin, was studied under aerobic conditions in isolated rat-liver nuclei. Kaempferol induced significant (P < 0.05) concentration-dependent nuclear DNA degradation

Topoisomerases are involved in many aspects of DNA metabolism such as replication and transcription reactions. Camptothecins, which stabilize the covalent intermediate of topoisomerase I and DNA are effective, though toxic, drugs for cancer therapy. In this study, a new class

Fifteen flavonoids were employed to examine their effects on the morphological changes, foci formation in soft agar and cellular growth in v-H-ras-transformed NIH3T3 cells. The data presented here demonstrated that only three specific flavonoids--apigenin, kaempferol, and genistein--exhibited the reverting effect

Fatty Acid Synthesis and Metabolism in Cancer Cells

Information on fatty acid synthesis and metabolism in cancer cells. Learn how proliferatively active cells require fatty acids for functions such as membrane generation, protein modification, and bioenergetic requirements. These fatty acids are derived either from dietary sources or are synthesized by the cell.

Dietary Antioxidants

Antioxidants protect biological systems from oxidative damage produced by oxygen-containing free radicals and from redoxactive transition metal ions such as iron, copper, and cadmium.
