Mexrenone (code names ZK-32055, SC-25152) is a steroidal antimineralocorticoid of the spirolactone group related to spironolactone that was never marketed.[1][2] It is the lactonic form of mexrenoic acid (mexrenoate), and mexrenoate potassium (SC-26714), the potassium salt of mexrenoic acid, also exists.[3] In addition to the mineralocorticoid receptor, mexrenone also binds to the glucocorticoid, androgen, and progesterone receptors.[4] Relative to spironolactone, it has markedly reduced antiandrogen activity (approximately one-tenth of the antimineralocorticoid dosage equivalent antiandrogen activity of spironolactone).[2] Eplerenone is the 9-11α-epoxy analogue of mexrenone.[5]
