| Bioactivity | Tectoridin is a isoflavone isolated from Maackia amurensis. Tectoridin is a phytoestrogen and activates estrogen and thyroid hormone receptors. Tectoridin exerts the estrogenic effects via ER-dependent genomic pathway and GPR30-dependent nongenomic pathway[1][2]. |
| Invitro | Tectoridin scarcely binds to ER alpha as compared to 17beta-estradiol and genistein[2].Tectoridin induceds potent estrogenic effects, namely recovery of the population of cells in the S-phase after serum starvation, transactivation of the estrogen response element, and induction of MCF-7 cell proliferation[2].Tectoridin induces estrogenic effect, and this effect is severely abrogated by treatment with U0126 ( MEK1/2 inhibitor). Tectoridin promotes phosphorylation of ERK1/2, but does not affect phosphorylation of ER alpha at Ser (118). It also increases cellular accumulation of cAMP[2]. |
