ORG-2058, also known as 16α-ethyl-21-hydroxy-19-norprogesterone, is a progestin of the 19-norprogesterone group which was never marketed.[1][2] It has high affinity for the progesterone receptor (775% of that of progesterone) and has been used in scientific research to study the role of the progesterone receptor in the body.[2] The drug has no affinity for the estrogen receptor or the glucocorticoid receptor (less than 0.2% of the affinities of estradiol and dexamethasone, respectively)[3] and has slight affinity for the mineralocorticoid receptor, but less than that of progesterone.[4]
