General description

Kaempferol is a natural dietary flavonoid and a polyphenol antioxidant found in various fruits and vegetables.[1] Kaempferol is present in plants in a different glycosidic form such as astragalin by binding with different sugars.[2]

Application

Chromogenic reagent for antimony in the low ppm range and for gallium and indium in the sub-ppm range.
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)[3]
  • to study its apoptosis sensitizing effect on non-small cell lung cancer (NSCLC) cells by inhibiting nuclear factor erythroid 2-related factor 2 (Nrf2)[4]

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.[2] 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.[5] It also inhibits topoisomerase I catalyzed DNA religation.[6] Kaempferol may also inhibit the activity of fatty acid synthase.

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

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

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
