Biological Activity
| ln Vitro | In dog ventricular myocytes, concentration-dependent reduction of NCX currents is observed with ORM-10962 (10 nM, 100 nM, and 1 μM), with estimated IC50 values of 55 and 67 nM mV at -80 and 20 mV, respectively [1]. |
| ln Vivo | In anesthetized guinea pigs, the administration of ORM-10962 (0.3 mg/kg, IV, once) markedly postpones the onset of anesthesia and premature ventricular contractions (about 50%) or ventricular tachycardia (about 30%) [1]. |
| Animal Protocol |
Animal/Disease Models: Male guinea pigs (250-300 g) [1] Doses: 0.3 mg/kg Route of Administration: intravenous (iv) (iv)injection, 10 minutes before starting ouabain infusion Experimental Results: Significant delay in the development of premature ventricular contractions (from 24 in the control group ±1.7 minutes to 36.6±2.7 minutes in the presence of drug) or ventricular tachycardia (from 31.8±1.8 minutes in the control group to 40.8±2.1 minutes in the presence of drug). |

Solubility Data
| Solubility (In Vitro) | DMSO : ~250 mg/mL (~544.02 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.53 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 20.8 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: ≥ 2.08 mg/mL (4.53 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 20.8 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: ≥ 2.08 mg/mL (4.53 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 20.8 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.) |
