Progesterone Receptors

Medroxyprogesterone acetate is a progestin, a synthetic variant of the human hormone progesterone and a potent progesterone receptor agonist.

Nestoron is a 19-norprogesterone derivative and steroidal progestin which is used as a hormonal contraceptive; a high-affinity agonist of the progesterone receptor.

Nomegestrol acetate is a potent, highly selective progestogen, which is characterized as a full agonist at the progesterone receptor, with no or minimal binding to other steroid receptors, including the androgen and glucocorticoid receptors.
