In Vitro

Kaempferol also has anti-inflammatory effects via inhibition of interleukin-4 and cyclo-oxygenase 2 expression by suppressing Src kinase and downregulating the NFκB pathway. Kaempferol is also effective in inhibiting angiogenesis and inducing apoptosis in ovarian cancer cells^[1]. Kaempferol is a natural flavonoid that is widely distributed in fruits and vegetables, and prospective studies revealed that over decades, consumption of Kaempferol dramatically and significantly reduces the risk of ovarian cancer in American female nurses. After a 24-hour treatment, Kaempferol causes a significant and concentration-dependent inhibition of proliferation in all 3 ovarian cancer cells tested. This inhibition is observed at 40 μM or higher concentrations of treatment^[2]. Kaempferol is a flavonoid which is abundant in a variety of plant derived food and leaves used in traditional medicines. Kaempferol significantly inhibits NADPH oxidase activity. Kaempferol decrease reactive oxygen species (ROS) by directly bound NADPH oxidase. Kaempferol prevents Ang II-induced sinus nodal cell death by lowering CAMKII oxidization^[3].10-20 μM Kaempferol dose-dependently suppresses its release in sensitized RBL-2H3 cells. When 10-20 μM Kaempferol is supplemented to DNP-BSA-challenged RBL-2H3 cells for 15 min, the activation of Syk and PLCγ is highly attenuated. When ≥10 μM Kaempferol is added to DNP-BSA-challenged RBL-2H3 cells for 60 min, the COX2 induction is reduced^[4].

In Vivo

The COX2 induction is confirmed in the airways of BSA-challenged BALB/c mice. There is lack of COX2 in airways of untreated control mice observed. The BSA inhalation to mice led to enhanced COX2 induction (dark brown staining) in mouse airway, which is reversed by oral administration of Kaempferol. In BSA-challenged mice, there is a marked goblet cell hyperplasia and epithelial thickening observed. When 20 mg/kg Kaempferol is supplemented to BSA-challenged mice, the epithelial thickening completely disappeared^[4].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2 mg/mL (6.99 mM); Clear solution

This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2 mg/mL (6.99 mM); Clear solution

This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2 mg/mL (6.99 mM); Clear solution

This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Working Solution

For the following dissolution methods, please prepare the working solution directly:

It is recommended to prepare fresh solutions and use them promptly within a short period of time.

The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 50% PEG300 50% Saline

Solubility: 10 mg/mL (34.94 mM); Suspended solution; Need ultrasonic

Protocol 2

Add each solvent one by one: 0.5% CMC/saline water

Kinase Assay^[3]

Right atria or sinus nodal cells are homogenized in lysis buffer consisting of (50 mM Tris-HCl pH 7.5, 100 mM KCl, 1 mM ethylenediamine tetraacetic acid, 1 mM ethylene glycol tetraacetic acid, 1 mM dithiothreitol, 0.1 mM phenylmethylsulfonyl fluoride, 0.5 mM Benzamidine, 20 mg/L Leupeptin, 20 mM sodium pyrophosphate, 50 mM NaF, and 50 mM sodium β-glycerophosphate), and total protein content is determined by the Bradford assay. Caspase-3 activity is determined by EnzChek Caspase-3 Assay Kit^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Assay^[2]

Ovarian cancer cells are seeded in 96-well plates at 2000 cells/well and incubated overnight before treatment with 0-160 μM Kaempferol for 24 hours in triplicates. The medium is removed, and the plates are freeze-thawed to lyse cells. Each well is added with 200 μL 1× CyQUANT cell lysis buffer containing 5x SYBR Green I and incubated at room temperature (RT) for 5 minutes. The reaction (50 μL) is transferred to PCR strip tubes and the fluorescent signal is measured at 90°C with a real-time Chromo4 PCR instrument. To ensure that cell proliferation assays are performed within a linear range of cell numbers, a standard curve is generated by seeding different amount of OVCAR-3 cells (based on counting with a hemacytometer) in a 96-well plate, and measuring genomic DNA abundance after overnight incubation. Three independent experiments are performed and data is pooled for statistical analysis^[2].

Animal Administration^[4]

Mice^[4]
Three-week-old male BALB/c mice are randomly assigned to the four treatment groups as follows (n=8 per group). (1) PBS-sensitized mice; (2) BSA-sensitized mice; (3) BSA-sensitized and 10 mg/kg Kaempferol-administered mice; and (4) BSA-sensitized and 20 mg/kg Kaempferol-administered mice. Mice are given a commercial mouse chow diet containing 20.5% protein, 3.5% fat, 8% fiber, 8% ash, and 0.5% phosphorus and are allowed access to food and water ad libitum. The mice are kept under a 12 h light and dark cycle at 23±1°C with 50%±5% relative humidity in specific pathogen-free conditions. Mice are allowed to become accustomed to their surroundings for one week before starting the allergic experiments. Sensitization of all experimental mice is carried out by subcutaneous injection with 20 μg BSA in 30 μL PBS and 50 μL Imject Alum on days 0 and 14. The control mice are injected with a combination of 50 μL PBS and 50 μL Imject Alum without BSA. On days 28, 29, and 30, only the experimental mice sensitized to BSA are subject to inhalation of 5% BSA, while control mice are challenged with 5% PBS for 20 min in a plastic chamber connected to a Medel aerosol nebulizer. All mice are sacrificed 24 h after the last challenge. Whole blood samples are directly used to measure the contents of eosinophils, basophils and neutrophils. The right lung is stored in 4% paraformaldehyde until use.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
