Biological Activity
| ln Vivo | LY2444296 showed anxiolytic-like effects in the EPM test [1]. LY2444296 (3 mg/kg; i.p.; 30 minutes before U69,593 administration) inhibits behavioral and neuroendocrine effects caused by the reference kappa agonist U69,593 in cocaine-naïve rats [2]. LY2444296 lowers anxiety-like and depressive-like behaviors and CORT release in rats assessed following chronic self-administration of cocaine, but not in cocaine-naïve rats [2] |
| Animal Protocol |
Animal/Disease Models: Adult male SD (SD (Sprague-Dawley)) rat (240–250 g) [2] Doses: 3 mg/kg Route of Administration: intraperitoneal (ip) injection; 30 minutes before administration of U69,593 Experimental Results: Prevention of U69,593 effects on the untreated Behavioral and neuroendocrine effects in rats exposed to cocaine. |

Solubility Data
| Solubility (In Vitro) | Ethanol : ~27.5 mg/mL (~67.33 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.75 mg/mL (6.73 mM) (saturation unknown) in 10% EtOH + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear EtOH stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 2: ≥ 2.75 mg/mL (6.73 mM) (saturation unknown) in 10% EtOH + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear EtOH stock solution to 900 μL of corn oil and mix well.  (Please use freshly prepared in vivo formulations for optimal results.) |
