From: A synthesis strategy for tetracyclic terpenoids leads to agonists of ERβ

28 and ent-28 are selective agonists of ERβ. a ERβ and ERα agonist assays (Z’ = 0.67 for ERβ Z’ = 0.77 for ERα, see Supplementary Information for experimental details). b 28 and ent-28 are agonists of ERβ in human DU-145 prostate cancer cells (17β-estradiol, 28, and ent-28 were evaluated at 5 µM). Error bars represent standard deviation of the mean (n = 6 per group), y-axis in OD 405 nM. Source data are provided as a Source Data File
