Kaempferol
Kaempferol (CAS: 520-18-3) is a naturally derived flavonoid isolated from sources including Gingko biloba and red wine. It functions biologically by activating the mitochondrial calcium uniporter (EC50 = 7 μM). Additionally, kaempferol promotes apoptosis through the caspase-9 pathway by suppressing polo-like kinase 1 (PLK1) expression, thereby inhibiting cancer cell proliferation in diverse cell lines. It also demonstrates antioxidant properties and reduces osteoclast-mediated bone resorption in vitro. These characteristics make kaempferol valuable for researching mitochondrial physiology, cancer biology, and bone metabolism.

|
Applications |
In CCA cells, kaempferol significantly inhibited the viability and proliferation of CCA cells in a time- and dose-dependent way. Kaempferol reduced the number of colonies and induced apoptosis in a dose-dependent way. Kaempferol also reduced the migration and invasion ability of CCA cells in a dose-dependent manner. |
| Animal experiment [1]: | |
|
Animal models |
subcutaneous xenograft nude mice model |
|
Dosage form |
20 mg/kg/day; daily for 3 weeks; i.p. |
|
Application |
In subcutaneous xenograft nude mice model, kaempferol significantly inhibited the growth of the tumor. The number of Ki-67-positive tumor cells was lower in kaempferol-treated group than that in the control group. Kaempferol reduced the average volume and number of foci per mouse. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
