OSU-ERβ-12 is a highly selective estrogen receptor beta (ERβ) full agonist which is under investigation for potential medical use, such as treatment of fibrosis.

Pharmacology

While OSU-ERβ-12 displays only a 3-fold binding selectivity for ERβ over the estrogen receptor alpha (ERα), it shows more than a 100-fold functional selectivity for ERβ over ERα, with values of 19–78nM and 3,828–30,000nM, respectively. The drug shows good drug-like properties and had superior pharmacokinetic properties to those of the earlier ERβ agonist erteberel (LY-500307) in preclinical research. It produces anti-fibrotic effects in rodents.

Chemistry

The chemical synthesis of OSU-ERβ-12 has been described. Various analogues of OSU-ERβ-12 have been described. OSU-ERβ-12 has an unusual para-carborane chemical structure.

History

It was first described in the scientific literature by 2020. The drug was developed by W. Tjarks and colleagues at Ohio State University.
