Disease
[RENI_HUMAN] Defects in REN are a cause of renal tubular dysgenesis (RTD) [MIM:267430]. RTD is an autosomal recessive severe disorder of renal tubular development characterized by persistent fetal anuria and perinatal death, probably due to pulmonary hypoplasia from early-onset oligohydramnios (the Potter phenotype).[1] Defects in REN are the cause of familial juvenile hyperuricemic nephropathy type 2 (HNFJ2) [MIM:613092]. It is a renal disease characterized by juvenile onset of hyperuricemia, slowly progressive renal failure and anemia.[2]
Function
[RENI_HUMAN] Renin is a highly specific endopeptidase, whose only known function is to generate angiotensin I from angiotensinogen in the plasma, initiating a cascade of reactions that produce an elevation of blood pressure and increased sodium retention by the kidney.
Publication Abstract from PubMed
The renin-angiotensin-aldosterone system (RAAS) plays a key role in the regulation of blood pressure. Renin, the first and rate-limiting enzyme of the RAAS, is an attractive target for the treatment of hypertension and cardiovascular/renal diseases. Therefore, various direct renin inhibitors (DRIs) have been researched over recent decades; however, most exhibited poor pharmacokinetics and oral bioavailability due to the peptidomimetic or nonpeptidomimetic structures with a molecular weight (MW) of >600, and only aliskiren is approved. This study introduces a novel class of DRIs comprised of a 2-carbamoyl morpholine scaffold. These compounds have a nonpeptidomimetic structure and a MW of <500. The representative compound 26 was highly potent despite not occupying S1'-S2' sites or the opened flap region used by other DRIs and exerted a significant antihypertensive efficacy via oral administration on double transgenic mice carrying both the human angiotensinogen and the human renin genes.
