KRI-1177
KRI-1177 is a competitive, dipeptide human renin inhibitor with a Ki of 0.7 μM and an IC50 of 90 nM. The IC50 of KRI-1177 targeting cynomolgus monkey renin is 680 nM. KRI-1177 acts as an antihypertensive agent, angiotensin inhibitor and plasma renin activity inhibitor, which reduces systemic blood pressure and plasma angiotensin concentration. KRI-1177 exhibits a relatively long-lasting antihypertensive effect in cynomolgus monkeys and can be used for hypertension research.

Description
In Vitro
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
KRI-1177 (0.1-5 mg/kg; i.v.; single bolus injection) produces only a slight, transient hypotensive effect (~12 mmHg fall in mean blood pressure at 5 mg/kg i.v.) in anesthetized Japanese monkeys on a normal diet[1].

-
Animal Model:Japanese monkey (Macaca fuscata) (both sexes, 6-9 kg, hypertension model via low sodium diet for 1 week, furosemide pretreatment, anesthetized with pentobarbital sodium)[1]
-
Dosage:0.1 mg/kg; 0.5 mg/kg; 1 mg/kg; 2.5 mg/kg; 5 mg/kg
-
Administration:i.v.; single bolus injection
-
Result:Produced a dose-dependent fall in systemic blood pressure.
Attained maximal hypotensive response of ~25 mmHg fall in mean blood pressure 5 minutes after 5 mg/kg i.v. injection, with half-maximal response restoration time of approximately 15 minutes.
Reduced plasma renin activity from pre-treatment mean of ~28 ng ANG I/mL per h to ~10 ng ANG I/mL per h after 1 mg/kg i.v. injection.
Reduced plasma renin activity from pre-treatment mean of ~50 ng ANG I/mL per h to ~5 ng ANG I/mL per h after 5 mg/kg i.v. injection.
Decreased plasma ANG I concentrations by 51.4% (from 1.62 ng/mL to 0.72 ng/mL) after 5 mg/kg i.v. injection.
Decreased plasma ANG II + III concentrations by 49.6% (from 149 pg/mL to 72 pg/mL) after 5 mg/kg i.v. injection.
Did not significantly alter heart rate at 5 mg/kg i.v.
