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
KRI-1177 (0.5 μM; 30 min) potently and selectively inhibits primate (human, Japanese monkey) plasma renin activity in vitro, with competitive inhibition of purified human renin (Ki = 0.7 μM), and far weaker inhibition of non-primate plasma renin and other proteolytic enzymes[1].
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.
