In histamine-stimulated parietal cells, ilaprazole (IY-81149) sodium has an IC50 of 9 nM for 14C-aminopyrine accumulation [1].

| ln Vivo |
Gastric acid secretion is dose-dependently inhibited by linaprozole sodium (3–30 mg/kg; id) [1]. Histamine infusion lowered stomach pH in sedated rats, but ilaprazole sodium dose-dependently raised it in intravenous injection cases. The injected doses of omeprazole (1.4 mg/kg) and sodium omeprazole (1.2 mg/kg) are the corresponding ED50s. The ED50s of omeprazole (4.1 mg/kg) and linaprazole sodium (3.9 mg/kg) when given, respectively. Significant inhibition of pentagastrin-stimulated gastric secretion is also observed with ilaprazole sodium. Omeprazole's ED50 is 3.5 mg/kg, whereas its is 2.1 mg/kg. when administering an intravenous injection. In fistula rats, ilaprazole sodium also significantly reduces the release of stomach acid. The ED50 for omeprazole is 0.68 mg/kg and for linaprazole sodium is 0.43 mg/kg when administered intraduodenally[1].

| Animal Protocol |
Animal/Disease Models: Male SD rat (after pylorus ligation)[1]
Doses: 3, 10, 30 mg/kg Route of Administration: Intraduodenally Experimental Results: The acid output and volume Dramatically inhibited by about 60 % and 46 % at 3 mg/kg were s, respectively. At 30 mg/kg, it demonstrated 93 % and 73 % inhibition on acid output and volume, respectively. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.36 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 (5.36 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. View More
Solubility in Formulation 3: ≥ 2.08 mg/mL (5.36 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
