Description
AC-186 is a non-steroidal estrogen receptor β (ERβ) agonist (EC50 = 6 nM in a functional assay).1 It is selective for ERβ over ERα (EC50 = 5,000 nM). AC-186 (10 mg/kg) reduces dopaminergic neuronal loss in the substantia nigra, improves novel object recognition, and improves motor performance in male, but not female, rats in a model of Parkinson’s disease induced by 6-OHDA (Item No. 25330). It reduces tactile allodynia in male, but not female or female ovariectomized, rats in a model of spinal nerve ligation-induced neuropathic pain.2 AC-186 (10 and 30 mg/kg) also reduces tactile allodynia in male rats in a model of neuropathic pain induced by paclitaxel
