Disease

[MCR_HUMAN] Defects in NR3C2 are a cause of pseudohypoaldosteronism 1, autosomal dominant (PHA1A) [MIM:177735]. A salt wasting disease resulting from target organ unresponsiveness to mineralocorticoids. PHA1A is a mild form characterized by target organ defects confined to kidney. Patients may present with neonatal renal salt wasting with hyperkalaemic acidosis despite high aldosterone levels. These patients improve with age and usually become asymptomatic without treatment.^[1] ^[2] ^[3] ^[4] ^[5] Defects in NR3C2 are a cause of early-onset hypertension with severe exacerbation in pregnancy (EOHSEP) [MIM:605115]. Inheritance is autosomal dominant. The disease is characterized by the onset of severe hypertension before the age of 20, and by suppression of aldosterone secretion.^[6] ^[7] ^[8] ^[9]

Function

[MCR_HUMAN] Receptor for both mineralocorticoids (MC) such as aldosterone and glucocorticoids (GC) such as corticosterone or cortisol. Binds to mineralocorticoid response elements (MRE) and transactivates target genes. The effect of MC is to increase ion and water transport and thus raise extracellular fluid volume and blood pressure and lower potassium levels.^[10]

Publication Abstract from PubMed

The mechanism-based risk for hyperkalemia has limited the use of mineralocorticoid receptor antagonists (MRAs) like eplerenone in cardio-renal diseases. Here we describe the structure and property driven lead generation and optimization, which resulted in identification of MR modulators ( S)-1 and ( S)-33. Both compounds were partial MRAs but still demonstrated equally efficacious organ protection as eplerenone after four weeks treatment in uninephrectomized rats on high salt diet and aldosterone infusion. Importantly, and in sharp contrast to eplerenone, this was achieved without substantial changes to the urine Na(+)/K(+) ratio after acute treatment in rat, which predicts a reduced risk for hyperkalemia. This work led to selection of ( S)-1 (AZD9977) as the clinical candidate for treating MR-mediated cardio-renal diseases including CKD and HF. Based on our findings we propose an empirical model for prediction of compounds with low risk of affecting the urinary Na(+)/K(+) ratio in vivo.
