Functions and Applications
1. Kaempferol was found to be active in promoting Opossum Kidney cell growth . Kaempferol stimulates kidney cells proliferation and increases secretion of bone growth factor . Kaempferol may serve to stimulate kidney repair and up-regulate bone formation and may be useful in treating chronic kidney disease and osteoporosis .
2. Kaempferol can inhibit the apoptosis induced by H202 in neonatal rat cardionyocytes . The protective effects could be related to their antiocidant activity and its ability to regulate the expression of Bcl-2 , Bax ,Caspase-3 protein .
3. Kaempferol is a blocker of voltagegated potassium channels in pyramidal neurons of rat hippocampus . The electrophysiological effects of kaempferol may be one mechanism of its protective effects on rat hippocampal neurons in acutely transient hypoxia .
4. Kaempferol owe to the strong antioxidant properties , can scavenge superfluous superoxide free radicals in human body , preventing DNA and cells from oxidative damage . It show pharmacological effects in anti-tumour ,anti-inflammation and anti-senility ,etc.
5. Kaempferol has the effect of anti-epilepsy , antispasmodic ,anthelone , antiulcer ,choleretic, diuretic activity and relieving cough .
