CP 71362
CP 71362 is a renin inhibitor, a highly potent substrate-analog transition state mimic with antihypertensive properties. CP 71362 exhibits significant inhibitory activity against plasma renin from rats, dogs, and humans (IC50 values are 3 nM, 0.0033 nM, and 20 nM, respectively). CP 71362 reduces the mean arterial pressure of anesthetized and conscious sodium-depleted animals in a dose-dependent manner, and has pharmacokinetic characteristics of rapid elimination and short duration of action. CP 71362 can be used in research related to hypertension and congestive heart failure.

Biological Activity
CP-71,362 exhibits high specificity for renin, with a potency 6 orders of magnitude lower against bovine spleen cathepsin D (IC50=1.3×10-6 M), and shows no inhibitory activity against rabbit lung ACE at concentrations up to 1×10-3 M[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
CP 71362 (9.7-30 μg/kg/min; i.v.; continuous infusion) reduces mean arterial pressure in conscious, sodium-depleted Sprague-Dawley rats, with an ED50 infusion rate of 9.7 μg/kg/min and a 30-40 mmHg pressure decrease at 30 μg/kg/min[1].
CP 71362 (0.1-3 mg/kg; i.v. bolus) produces dose-dependent mean arterial pressure lowering in conscious, sodium-depleted Cavia porcellus, with the 1.0 and 3.0 mg/kg bolus doses maintaining significant effects for at least 2 hours[2].
CP 71362 (1.06-100 μg/kg/min; i.v. infusion; 10-30 minutes) produces dose-dependent, reversible mean arterial pressure lowering in anesthetized, sodium-depleted dogs, with an ED50 of 1.06 μg/kg/min, and completely suppresses plasma renin activity at the ED50 dose[2].
CP 71362 (4.3-43.3 μg/kg/min; i.v. infusion; 30 minutes) produces rapid, dose-dependent, fully reversible mean arterial pressure lowering in conscious, sodium-depleted SHR, with an ED50 of 5 μg/kg/min[2].
