Ki: ~1 nM (KOPR)[1]

In Vivo LY2444296 displays anti-anxiety like effects in the EPM test[1]. LY2444296 (3 mg/kg; i.p.; 30 min before U69,593 administration) prevents behavioral and neuroendocrine effects caused by the reference kappa agonist U69,593 in cocaine-naïve rats[2]. LY2444296 reduces anxiety-like and depressive-like behaviors, as well as CORT release, in rats tested after chronic extended access cocaine self-administration, but not in cocaine-naïve rats[2]. Animal Model: Adult male Sprague Dawley rats (240–250 g)[2] Dosage: 3 mg/kg Administration: Injected intraperitoneally; 30 min before U69,593 administration Result: Prevented behavioral and neuroendocrine effects caused by U69,593 in cocaine-naïve rats.
