Spironolactone (I), a potassium sparing diuretic, is widely used in the treatment of edema. Metabolic degradation starts with rapid deacetylation, leading to the short lived a-thiol [l]. Subsequent elimination of hydrogen sulfide yields canrenone (II), which exists in enzymatic equilibrium with canr
