SC-8109 is a steroidal antimineralocorticoid of the spirolactone group which was never marketed.[1][2] It is a potent antagonist of the mineralocorticoid receptor and is more potent than the related drug SC-5233 (of which SC-8109 is the 19-nor analogue).[1][3] However, SC-8109 was found to have relatively low oral bioavailability and potency,[1][4] though it nonetheless produced a mild diuretic effect in patients with congestive heart failure.[2] Spironolactone (SC-9420; Aldactone), another spirolactone, followed and had both good oral bioavailability and potency, and was the first antimineralocorticoid to be marketed.[1][5]

In addition to its antimineralocorticoid activity, SC-8109 shows potent progestogenic activity, with similar potency relative to that of progesterone.[6] Its analogue, SC-5233, possesses similar but less potent progestogenic activity.[6] In addition, SC-5233 has been assessed and found to possess some antiandrogenic activity, antagonizing the effects of testosterone in animals, and SC-8109 may as well.[7]

Relative affinities (%) of SC-8109 and related steroids[8]
Compound PR AR ER GR MR SHBG CBG
Progesterone 100 3–10 <1 <1 3–10 ? ?
SC-8109 191 25–50 <1 <1 15–25 ? ?
Values are percentages (%). Reference ligands (100%) were progesterone for the PR, testosterone for the AR, estradiol for the ER, DEXA for the GR, and aldosterone for the MR.
