== Disease ==
[https://www.uniprot.org/uniprot/MCR_HUMAN MCR_HUMAN] Defects in NR3C2 are a cause of pseudohypoaldosteronism 1, autosomal dominant (PHA1A) [MIM:[https://omim.org/entry/177735 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.<ref>PMID:9662404</ref> <ref>PMID:11134129</ref> <ref>PMID:12788847</ref> <ref>PMID:16954160</ref> <ref>PMID:16972228</ref>   Defects in NR3C2 are a cause of early-onset hypertension with severe exacerbation in pregnancy (EOHSEP) [MIM:[https://omim.org/entry/605115 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.<ref>PMID:9662404</ref> <ref>PMID:15967794</ref> <ref>PMID:15908963</ref> <ref>PMID:10884226</ref> 
== Function ==
[https://www.uniprot.org/uniprot/MCR_HUMAN 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.<ref>PMID:3037703</ref>

== Publication Abstract from PubMed ==
Dihydrofuran-2-one and dihydropyrrol-2-one derivatives were identified as novel, potent and selective mineralocorticoid receptor (MR) antagonists by the structure-based drug design approach utilizing the crystal structure of MR/compound complex. Introduction of lipophilic substituents directed toward the unfilled spaces of the MR and identification of a new scaffold, dihydropyrrol-2-one ring, led to potent in vitro activity. Among the synthesized compounds, dihydropyrrol-2-one 11i showed an excellent in vitro activity (MR binding IC50=43nM) and high selectivity over closely related steroid receptors such as the androgen receptor (AR), progesterone receptor (PR) and glucocorticoid receptor (GR) (&gt;200-fold for AR and PR, 100-fold for GR).

Design, synthesis, and structure-activity relationships of dihydrofuran-2-one and dihydropyrrol-2-one derivatives as novel benzoxazin-3-one-based mineralocorticoid receptor antagonists.,Hasui T, Ohra T, Ohyabu N, Asano K, Matsui H, Mizukami A, Habuka N, Sogabe S, Endo S, Siedem CS, Tang TP, Gauthier C, De Meese LA, Boyd SA, Fukumoto S Bioorg Med Chem. 2013 Oct 1;21(19):5983-94. doi: 10.1016/j.bmc.2013.07.043.
