Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
1.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 20 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil
0.4mg/ml Taking the 1 mL working solution as an example, add 50 μL of 8 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Kaempferide (4'-Methylkaempferol, 4'-O-Methylkaempferol, Kaempferol 4'-methyl ether), a natural compound derived from the roots of kaempferia galanga, has a variety of effects including anti-carcinogenic, anti-inflammatory, anti-oxidant, anti-bacterial and anti-viral properties.
In vitro Kaempferide is able to induce apoptosis in the "side population" (SP, a subpopulation enriched with CSC in various cancers) cells in myeloma. It reverses the activity of drug efflux transporter[2]. Kaempferide is non-toxic to normal fibroblasts while inducing morphological changes, membrane flip-flop and nuclear membrane damage, characteristic of apoptosis in HeLa cells. It is highly cytotoxic to cervical cancer cells. Kaempferide-induced cytotoxicity is independent of cell cycle arrest[3].
In vivo Kaempferide (Kae) remarkably improves cardiac function, alleviates myocardial injury via a decrease in myocardial enzyme levels, and attenuates myocardial infarct size in a dose-dependent manner. It attenuates I/R-induced myocardial injury through inhibition of the Nrf2 and cleaved caspase-3 signaling pathways via a PI3K/Akt/GSK 3β-dependent mechanism. Preconditioning treatment with Kae significantly decreases serum TNF-α, IL-6, C-reactive protein (CRP), MDA, and ROS levels, while increases serum levels of SOD. Nuclear factor erythroid 2-related factor 2 (Nrf2) and cleaved caspase-3 expression levels are downregulated, while phospho-Akt (p-Akt) and phospho-glycogen synthase kinase-3β (p-GSK-3β) expression levels are upregulated[1]. Kaempferide is non-toxic as assessed by acute and chronic toxicity studies in Swiss albino mice in vivo[3].

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    KMS-11 cells

  • Concentrations

    4-64 μM

  • Incubation Time

    24 h

  • Method

    Unfractionated cells are seeded at 20000 cells per well in a 96 well plate. After 24h of incubation with various concentration of KFD, PAR, and DMSO (vehicle control), MTS solution is added and absorbance at 490 nm is determined.
