Progesterone receptor (PR) is a protein found inside cells, which is activated by the steroid hormone progesterone. In humans, PR is encoded by a single PGR gene residing on chromosome 11q22, it has two main forms, A and B, that differ in their molecular weight. Progesterone is necessary to induce the progesterone receptors. When no binding hormone is present the carboxyl terminal inhibits transcription. Binding to a hormone induces a structural change that removes the inhibitory action. Progesterone antagonists prevent the structural reconfiguration. After progesterone binds to the receptor, restructuring with dimerization follows and the complex enters the nucleus and binds to DNA. There transcription takes place, resulting in formation of messenger RNA that is translated by ribosomes to produce specific proteins. Progesterone receptor plays a central role in diverse reproductive events associated with establishment and maintenance of pregnancy, alveolar development in the breast and sexual behavior.

Medroxyprogesterone 17-acetate

Medroxyprogesterone acetate is a progestin, a synthetic variant of the human hormone progesterone and a potent progesterone receptor agonist.Target: Progesterone ReceptorMedroxyprogesterone acetate(MPA) is a steroidal progestin, a synthetic variant of the human hormone progesterone. It is used as a contraceptive, in hormone replacement therapy and for the treatment of endometriosis as well as several other indications. MPA is a more potent derivative of its parent compound medroxyprogesterone (MP). While medroxyprogesterone is sometimes used as a synonym for medroxyprogesterone acetate, what is normally being administered is MPA and not MP [1, 2].

medroxyprogesterone

Medroxyprogesterone is a progestin, a synthetic variant of the human hormone progesterone and a potent progesterone receptor agonist.Target: Progesterone ReceptorMedroxyprogesterone (MP), is a steroidal progestin drug which was never marketed for use in humans. An acylated derivative, medroxyprogesterone acetate (MPA), is clinically used as a pharmaceutical medicine. Compared to MPA, MP is over two orders of magnitude less potent as a progestogen. As such, MP itself is not used clinically, though it has seen limited use in veterinary medicine under the trade name Controlestril in France. In addition, it is an metabolite of MPA [1].
