Imarikiren, formerly known as TAK-272, is a potent, selective and orally bioavailable direct renin inhibitor for the treatment of diabetic nephropathies. TAK-272 showed potent inhibitory activity against human renin (IC50 = 2.1 nM) in hPRA assay and excellent selectivity against other aspartic proteases, such as pepsin (IC50 > 10 μM) and cathepsin D (IC50 > 10 μM). TAK-272 exhibited a dramatically improved PK profile in rats (F = 25.2%). TAK-272 (3 and 10 mg/kg, p.o.) exhibited potent and long-lasting antihypertensive efficacy in a dose-dependent manner. TAK-272 HCl is currently undergoing human clinical trials. References:
