Uses
(-)-8-Prenylnaringin is a prenylflavonoid, a class on non-steroidal phytoestrogen that mimicks and/or modulating endogenous estrogens via estrogen receptor binding.
Definition
ChEBI: Sophoraflavanone B is a trihydroxyflavanone that is (S)-naringenin having a prenyl group at position 8. It has a role as a platelet aggregation inhibitor and a plant metabolite. It is a trihydroxyflavanone, a member of 4'-hydroxyflavanones and a (2S)-flavan-4-one. It is functionally related to a (S)-naringenin. It is a conjugate acid of a sophoraflavanone B(1-).
Biological Activity
8-prenylnaringenin is an estrogen receptor inhibitor.the two estrogen receptors erα and erβ belong to the nuclear receptor superfamily and are ligand-regulated transcription factors accounting for mediating the physiological effects of the steroid hormone 17α-estradiol. er is an established target for the development of synthetic ligands for therapeutic applications.
in vitro
previous study identified 8-prenylnaringenin as a potent phytoestrogen in hops, which had an activity greater than other known plant estrogens. the estrogenic activity of 8-prenylnaringenin was reflected in its relative binding affinity to estrogen receptors from rat uteri. in addition, the presence of 8-prenylnaringenin in hops might explane the accounts of menstrual disturbances in female hop workers [1].
in vivo
previous animal data demonstrated that 8-prenylnaringenin treatment could result in ampk signaling pathway activation, therefore suppressing lipogenesis. the consumption of 8-prenylnaringenin was able to prevent body weight gain and improve plasma lipid profile, with significant improvement of insulin resistance and glucose tolerance. moreove, it was found that 8-prenylnaringenin-enriched diet could ameliorate diabetic-associated metabolic disturbances via regulating glucose and lipid pathways [2].
IC 50
57 and 68 nm for erα and erβ, respectively
