Renal hemodynamic and excretory responses to renin inhibition induced by A-64662.

Experiments were conducted in sodium-depleted anesthetized monkeys to determine the effects of the primate-selective renin inhibitor A-64662 on renal function. Five groups of monkeys were examined with each group receiving an i.v.

Intraocular pressure lowering effects of the renin inhibitor ABBOTT-64662 diacetate in animals.

Corneal application of enalkiren (ABBOTT-64662), [N-(3-amino-3-methyl-1- oxobutyl)-4-methoxy-L-phenylalanyl]-N-[1S,2R,3S)-1-(cyclohexylmethyl+ ++)-2,3- dihydroxy-5-methylhexyl]-L-histidinamide], a renin inhibitor compound, lowered intraocular pressure (IOP) in unanesthetized rabbits and anesthetized monkeys. IOP was significantly decreased for at least 60 minutes after administration of a 0.3% solution of enalkiren in monkeys and for at least 90 minutes after the administration of 0.

Effects of chronic infusion of renin inhibitor A-64662 in sodium-depleted monkeys.

The potent and primate-selective renin inhibitor A-64662 (n = 8) or vehicle (n = 6) was administered intravenously for 7 days to sodium-depleted cynomolgus monkeys to investigate the chronic effects on arterial pressure, sodium excretion, and the renin-angiotensin-aldosterone system. A 0.1-mg/kg i.

Cardiovascular actions of the primate-selective renin inhibitor, A-62198.

A-62198 [dimethylacetyl-Phe-His-NHCH(cyclohexylmethyl)CH-(OH)C H(OH)CH2N3] is a potent, selective inhibitor of primate renin. This compound induced a dose-dependent fall in mean arterial blood pressure (MAP) when administered as an i.v.
