Mecigestone
Mecigestone is a synthetic, steroidal progestin that was never marketed. It is a progestogen and hence is a agonist of the progesterone receptor, the biological target of progestogens like progesterone. Mecigestone has strong progestogenic activity and weak glucocorticoid and antimineralocorticoid activity.
