β-LGND2, also known as ERβ-selective ligand 2 or as GTx-878, is a synthetic nonsteroidal estrogen and selective ERβ agonist which was under development by GTx for the treatment of benign prostatic hyperplasia, prostatitis, and rheumatoid arthritis but was never marketed.[1][2][3][4][5][6] It shows approximately 25-fold selectivity for activation of the ERβ over the ERα (EC50Tooltip half-maximal effective concentration = 2 nM and 52 nM, respectively).[3] β-LGND2 is an isoquinolinone derivative.[2][5]

We found that β-LGND2, also known as GTx-878 (GTx, Inc. (31)), reduces body weight and fat mass without altering feed consumption of high-fat diet (HFD)-fed WT, but not ER-βKO, mice.
