Biological Activity
| ln Vivo | Male OF-1 mice were dose-dependently protected against maximal electroshock epileptic seizures (MES) by treatment with SDZ 220-581 (3.2–32 mg/kg; p.o.; for 24 hours). The quick onset and extended duration of action of SDZ 220-581 are characteristics of its protective duration [1]. |
| Animal Protocol |
Animal/Disease Models: Male OF-1 mouse (18-26g) [1] Doses: 3.2mg/kg, 10mg/kg, 32mg/kg Route of Administration: Oral administration; Route of Administration: Oral administration. 24-hour Experimental Results: Dose-dependent protection of mice from maximal electroshockable seizures (MES) following oral administration. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~8.57 mg/mL (~23.18 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.76 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% 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 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.76 mM) (saturation unknown) in 10% DMSO + 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 25.0 mg/mL clear DMSO 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 3: ≥ 2.5 mg/mL (6.76 mM) (saturation unknown) in 10% DMSO + 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 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
