Esaxerenone

Esaxerenone (INN) (brand name Minnebro; developmental code names CS-3150, XL-550) is a nonsteroidal antimineralocorticoid which was discovered by Exelixis and developed by Daiichi Sankyo Company and is approved in Japan for the treatment of hypertension. It acts as a highly selective silent antagonist of the mineralocorticoid receptor (MR), the receptor for aldosterone, with greater than 1,000-fold selectivity for this receptor over other steroid hormone receptors, and 4-fold and 76-fold higher affinity for the MR relative to the existing antimineralocorticoids spironolactone and eplerenone. As of January 2019, esaxerenone is in phase III clinical trials for diabetic nephropathies.
