title: Aldosterone antagonists. 4. Synthesis and activities of steroidal 6,6-ethylene-15,16-methylene 17-spirolactones.
abstract: Several steroidal 6,6-ethylene-15,16-methylene 17-spirolactones were synthesized to find new progestogens that exhibit both progestational and antimineralocorticoidal activities. The influence of substituents in the 10- and 13-position of the steroidal framework on both properties was investigated. It was found that only compound 12, carrying methyl groups at the 10- and 13-positions, possesses high progestational and antimineralocorticoidal activity.
