SQ 31844 is a novel renin inhibitor belonging to the imidazolidinol class. This compound, which contains an imidazole ring in its active site binding group, has potent in vitro inhibition of primate renin, but not rat, pig, or dog renin. In conscious, sodium-deprived cynomolgus monkeys, both compounds produced dose-related inhibition of plasma renin activity (PRA) over a dose range of 0.001 to 1.0 μmol/kg, administered intravenously, with complete inhibition observed at the highest dose. However, a reduction in blood pressure was only observed when 10 μmol/kg was administered intravenously or by infusion. In sodium-replete monkeys, SQ 30774 inhibited the increase in arterial blood pressure and PRA following administration of exogenous monkey renin. When the compounds were administered orally at 50 μmol/kg, only SQ 31844 significantly inhibited PRA (80%). In summary, the imidazolidinol renin inhibitors have potent inhibitory effects on renin in vitro and inhibit PRA and reduce arterial blood pressure in vivo.

Renin inhibitory peptide, statine is an inhibitor of Renin. Renin inhibitory peptide, statine inhibits the plasma renin activity of human plasma renin, porcine renin, and sodium-depleted conscious dogs. Renin inhibitory peptide, statine reduces the mean arterial pressure of sodium-depleted conscious dogs, induces a sustained, dose-dependent decrease in blood pressure, and triggers a maximum hypotensive response. Renin inhibitory peptide, statine can be used in hypertension-related research .

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 .
