Compounds of the formula (I), (R1 is one of a wide range of substituents; R2 = H, halogen and R3 = H, hydroxymethyl or CR2R3 = cyclopropyl ring; CR4R5 is one of formula (II), formula (III) and formula (IV) Ra and Rb are a bond between carbons 9 and 11 or an -O-, -S-, -CH2- or -CF2- bridge; R6 is H, alkyl, -CH2ORx, -CH2SRx, -CH2SO-alkyl, -CH2SO2-alkyl, -CH2NHRx, -CH2N(alkyl)(Rx), -C(=O)O-alkyl, -C(=O)-alkyl, -C(=O)NHRx or -C(=O)N(alkyl)(Rx); R7 = R8 = H or CR7R8 is a cyclopropyl ring; R9 and R9’ are H, halogen, alkyl or alkoxycarbonyl or a bond between carbons 22 and 23; R10 is H or -C(=O)ORx; Rx is H, alkyl or acyl; Ry is H, alkyl; Rz is H, alkyl) are provided. They are aldosterone receptor antagonists, useful for the treatment of aldosteronism including hypertension, cardiovascular disease, renal dysfunction, edema, cerebrovascular disease and insulinopathies.

In the search for aldosterone antagonists with an optimal activity profile, twelve 9α,11-epoxy-steroids were prepared and compared with their 9α,11α-unsubstituted analogues in terms of steroid receptor binding in vitro and electrolyte excretion in vivo. Substitution of the parent structures by an epoxy group at positions 9α,11 resulted in marginal effects on mineralocorticoid receptor binding and electrolyte excretion, but greatly reduced androgen and gestagen receptor binding. This finding is reflected in the largely lacking unwanted anti-androgenic and gestagenic side effects in animal models of the three most interesting 9α,11-epoxy-spirolactones 4(CGP 33033), 18(CGP 29245), and 25(CGP 30083).
