Biological Activity of Sagittatoside A
| Description | Sagittatoside A selectively activates estrogen response element (ERE)-luciferase activity via ERα, and sagittatoside A and icariin induces ERα phosphorylation at serine 118 residue. |
| Targets | NF-kB | Estrogen receptor | Progestogen receptor |
| In vitro |
Flavonoids from Herba epimedii selectively activate estrogen receptor alpha (ERα) and stimulate ER-dependent osteoblastic functions in UMR-106 cells.[Pubmed: 24607839] J Steroid Biochem Mol Biol. 2014 Sep;143:141-51. Total flavonoids in Herba epimedii (HEP) have been demonstrated to protect against bone loss and bone deterioration associated with estrogen deficiency without exerting any uterotrophic effects. However, it is unclear how flavonoids in HEP exert their protective effects on bone and if different flavonoids exert estrogenic actions in bone cells via similar mechanism of actions. |

Flavonoids from Herba epimedii selectively activate estrogen receptor alpha (ERalpha) and stimulate ER-dependent osteoblastic functions in UMR-106 cells.[Pubmed:24607839]
J Steroid Biochem Mol Biol. 2014 Sep;143:141-51.
Total flavonoids in Herba epimedii (HEP) have been demonstrated to protect against bone loss and bone deterioration associated with estrogen deficiency without exerting any uterotrophic effects. However, it is unclear how flavonoids in HEP exert their protective effects on bone and if different flavonoids exert estrogenic actions in bone cells via similar mechanism of actions. The present study aims to investigate the bone anabolic effects of four major flavonoids isolated from HEP, namely icariin, baohuoside-I, epimedin B and Sagittatoside A as well as the mechanism involved in mediating their estrogenic actions in rat osteoblastic-like UMR-106 cells. All tested compounds significantly stimulated the cell proliferation rate, alkaline phosphate (ALP) activity and osteoprotegerin (OPG)/receptor activator of nuclear factor kappa-B ligand (RANKL) mRNA expression in UMR-106 cells and their effects could be abolished by co-incubation with 10(-6)M ICI 182,780. None of the flavonoids exhibited binding affinities toward ERalpha and ERbeta. However, Sagittatoside A selectively activated estrogen response element (ERE)-luciferase activity via ERalpha. In addition, icariin and Sagittatoside A induced ERalpha phosphorylation at serine 118 residue. Taken together, our results indicated that all four flavonoids from HEP stimulated ER-dependent osteoblastic functions in UMR-106 cells, but only two of them appeared to exert their actions by ligand-independent activation of ERalpha. Our study provides evidence to support the hypothesis that the estrogen-like protective effects on bone by flavonoids are mediated via mechanisms that are distinct from the classical actions of estrogen.
Effect of stability of internal standard on quantification of 15 flavonoids in Epimedium using CZE.[Pubmed:19101945]
J Sep Sci. 2009 Jan;32(2):275-81.
A CZE method was developed for the simultaneous determination of 15 flavonoids, including epimedin B, epimedin A, hexandraside F, epimedin C, icariin, sagittatoside B, Sagittatoside A, hexandraside E, 2''-O-rhamnosyl icariside II, baohuoside VII, baohuoside I, caohuoside C, epimedoside C, baohuoside II, and kaempferol-3-O-rhamnoside, in different species of Epimedium, and the effect of stability of internal standard (IS) on quantification was also investigated. As a result, rutin was not available for use as an IS because of its unstable property in sample solution, which suggested that the stability of IS both in standards and sample solution should be considered for the analysis. Using stable daidzein as IS, the analysis was performed within 35 min by using 50 mM borax buffer containing 20% ACN as a modifier (pH 10.0), while separation voltage was 25 kV and temperature was at 30 degrees C. The method was validated to be accurate, simple, and repeatable, and was successfully applied to the analysis of 36 samples from 17 species of Epimedium.
