Biological Description

Description as a novel transcriptional up-regulator of scavenger receptor class B type I in HepG2 cells.

Targets(IC50) AChR: None NF-κB: None Beta Amyloid: None In vitro Protective effect of five (, , Pratensein, and ) from Trifolium pratense on lipopolysaccharide-induced dopaminergic neurodegeneration was studied for the first time. The results showed that all five isoflavones attenuated LPS-induced decrease in dopamine uptake and the number of dopaminergic neurons in a dose-dependent manner in rat mesencephalic neuron-glia cultures. Moreover, they also significantly inhibited LPS-induced activation of microglia and production of tumor necrosis factor-alpha, nitric oxide and superoxide in mesencephalic neuron-glia cultures and microglia-enriched cultures. In addition, the rank order of protective potency of five isoflavones was: Pratensein>daidzein>calycosin>formononetin>irilone.
