Notes: Estrogen action is mediated through two estrogen receptor (ER) subtypes, ERα and ERβ, which have distinct target tissue distributions and functional activities.{10559} Methylpiperidino pyrazole is an ER antagonist that is highly selective for ERα compared to ERβ (Kis = 5.6 nM and 2.3 μM, respectively).{21951} It can inhibit ERα transcriptional activation with an IC50 value of 80 nM.{21949} It has been used to evaluate the role of ERα in various estrogen-responsive systems, including certain cancers.{21950}
