Description

Libenzapril (CGS 16617) is a potent angiotensin-converting enzyme inhibitor used to study myocardial injury.

In vivo

The effect of intravenous (i.v.) libenzapril was studied in six healthy males by administering i.v. angiotensin I (AI) was administered in stepwise increments of 20 ng/kg/5 min until the subjects' systolic blood pressure (SBP) had increased 20-30 mm Hg above baseline. The mean baseline infusion of 63 ng/kg/5 min resulted in a significant (P < 0.05) increase in the ratio of AII to AI plasma levels from 0.52 +/- 0.46 to 7.92 +/- 4.48 and a SBP increase of 120 +/- 7.1 to 147 +/- 5.6. Within 15 minutes of starting the 1-mg infusion of libenzapril over 1.5 hours, the AII/AI ratio decreased to baseline values, and the SBP returned to baseline in 1 hour. Repeat AI challenges at 3.5 and 5 hours postdose did not increase SBP significantly. Even the 6.5-hour challenge demonstrated only a slight increase in SBP, with an AII/AI ratio of 0.26. At 24 hours, SBP was only 40% of the baseline response, demonstrating that libenzapril is a potent long-acting ACE inhibitor.[1]

The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
