Propylpyrazoletriol (PPT) is a synthetic, nonsteroidal agonist of ERα with 400-fold selectivity over ERβ[1] that is used widely in scientific research to study the function of ERα.[2][3][4] Though originally thought to be highly selective for ERα, PPT has subsequently been found to also act as an agonist of the GPER (GPR30).[5]
