WAY-200070 is a selective estrogen receptor beta (ERβ) agonist, a synthetic compound developed for research purposes. It exhibits high binding affinity for ERβ over estrogen receptor alpha (ERα), making it a valuable tool for studying the distinct biological functions mediated by ERβ signaling. In preclinical studies, WAY-200070 has shown potential neuroprotective, anti-inflammatory, and antidepressant-like effects, and it has also been investigated for its role in modulating hair growth and skin biology. However, it remains an experimental compound and is not currently approved for clinical use in humans.
