|Description||Ramipril is an angiotensin-converting enzyme (ACE) inhibitor with IC50 of 5 nM.|
|Features||A pro-drug converted to its active metabolite, ramiprilat, by liver esterase enzymes.|
Ramipril is an angiotensin-converting enzyme (ACE) inhibitor with IC50 of 5 nM.  Ramipril enhances the activity of ACE-associated CK2 and the phosphorylation of ACE Ser1270 in cultured endothelial cells, but is unable to activate JNK or stimulate the nuclear accumulation of c-Jun in endothelial cells expressing a S1270A ACE mutant or in ACE-deficient cells. Prolonged Ramipril treatment increases ACE expression in primary cultures of human endothelial cells and in vivo (mouse lung), which can be prevented by pretreatment with the JNK inhibitor SP600125.  Ramipril displays little enhanced effect on the rate of in vitro endothelial apoptosis induced by the serum deprivation method. 
|In vivo||Chronic in vivo administration of Ramipril to rats at a dosage that has similar hypotensive effects in vitro HUVECs significantly reduces the rate of LPS-induced apoptosis compared to the other ACE inhibitors, which contrasts with the apoptosis effect in vitro.  Ramipril inhibits systolic blood pressure (SBP) with IC50 of 1.97 mg/kg in spontaneously hypertensive rats (SHR). When in combination with AT1-receptor blockade by candesartan-cilexetil increases SBP reduction synergistically rather than additively.  Administration of Ramipril to spontaneously hypertensive rats (SHR) produces significant inhibition of aorta ACE and lung ACE with IC50 ~5 mg/kg, but shows little effect for brain ACE ex vivo.  Ramipril prevents beta cell dysfunction in osteoprotegerin treated mice through decreasing islet monocyte/macrophage infiltration, fibrosis and apoptosis involving decreasing RAS, growth factor genes and inflammatory molecules expressions. |

|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
30% PEG400+0.5% Tween80+5% propylene glycol
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
