Erteberel is a highly selective estrogen receptor β (ERβ) agonist. | [Biological Activity]
erteberel (ly500307) is a potent and selective erβ (estrogen receptor beta) agonist (ec50 = 0.66 nm). [1]estrogen receptors are nuclear hormone receptors that act as a ligand-activated transcription factor. it regulates gene expression, cell proliferation and differentiation in target tissues and involved in breast cancer, endometrial cancer and osteoporosis etc. [1]in transcription assay of cotransfected human prostate cancer cell line, erteberel showed potency (ec50 = 0.66 nm), selectivity (32-fold) and full agonist function (>90% relative efficacy) to erβ than to erα. [1]in mouse model, prostate wet weight of cd-1 mice were measured following oral daily doses of erteberel for 7 days. results showed reduction on prostate weight in a dose-dependent manner (0.01 mg/kg – 0.05 mg/kg), and no effect on testes/seminal vesicle weight and androgens testosterone/dihydrotestosterone circulating level.
