Purity: ≥98%
Imidapril HCl (TA-6366; TA-6366; Tanatril), the hydrochloride salt of imidapril, is a potent angiotensin-converting enzyme (ACE) inhibitor with IC50 of 2.6 nM, approved in 1993 for use as an antihypertensive drug and for the treatment of chronic heart failure. As a prodrug, imidapril is converted by hydrolysis in the liver into its active form imidaprilat. Imidaprilat competitively binds to and inhibits ACE, thereby blocking the conversion of angiotensin I to angiotensin II. This prevents the potent vasoconstrictive actions of angiotensin II and results in vasodilation. Imidaprilat also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex, which leads to an increase in sodium excretion and subsequently increases water outflow.
| ln Vitro |
Matrix metalloproteinase (MMP) plays a critical role in the development of ventricular remodeling after acute myocardial infarction (AMI). Imidapril, an angiotensin-converting enzyme inhibitor, has been shown to inhibit MMP activity. We investigated whether imidapril inhibits plasma MMP activities and attenuates ventricular remodeling in patients with AMI in comparison with enalapril. We enrolled 70 patients with AMI. All patients underwent primary percutaneous coronary intervention and were randomly assigned either to imidapril (n = 35) or to enalapril (n = 35) treatment. Left ventriculography was performed in acute (day 14) and chronic (6 months) phases, and plasma MMP-2 and MMP-9 activities were measured by zymography. Any changes in left ventricular end-diastolic volume index and ejection fraction from acute to chronic phases did not differ between the 2 groups. The plasma MMP-2 and MMP-9 activities at day 14 were both significantly decreased compared with those at day 1 in both groups (all P < 0.05). At 6 months, MMP-9 activity still remained decreased in both groups (P < 0.05 vs. day 1). Overall, there were no differences between the 2 groups both in plasma MMP-2 and MMP-9 activities. These results demonstrate that imidapril exerts inhibitory effects on plasma MMP activities and attenuates left ventricular remodeling in patients with AMI similar to enalapril.[1]

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 (5.66 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.

*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.
