Abstract: Several steroid derivatives having the delta 11-pregnane skeleton with a 17-gamma-spirolactone function were synthesized to evaluate their antialdosterone activity and to elucidate the relation between their binding affinity to mineralocorticoid receptor (MR) and their mineralo- and/or antimineralocorticoid activity. Although many of the synthesized compounds showed strong binding affinity for the MR and aldosterone agonist activity, 3-(17 beta-hydroxy-3-oxoandrosta-1,4,6,11-tetraen-17 alpha-yl)propionic acid gamma-lactone exhibited good aldosterone antagonist activity in an in vivo assay. Its in vivo antiandrogenic activity was also found to be relatively weak.
