The progesterone receptor (PR), also known as NR3C3 or nuclear receptor subfamily 3, group C, member 3, is a protein found inside cells. It is activated by the steroid hormone progesterone . In humans, PR is encoded by a single PGR gene residing on chromosome 11q 22, [ 5 ] [ 6 ] [ 7 ] it has two isoforms, PR-A and PR-B , that differ in their ...
Medroxyprogesterone acetate (Amen, Curretab, Cycrin, Provera) – 2.5 mg, 5 mg, 10 mg; Megestrol acetate (Megace) – 20 mg, 40 mg – approved specifically for the treatment of breast and endometrial cancer [46] and for the treatment of anorexia, cachexia, and weight loss in patients with AIDS Tooltip acquired immunodeficiency syndrome [47]
5β-DHP has been found to act as a positive allosteric modulator of the GABA A receptor (albeit with an affinity for this receptor regarded as relatively low in comparison to 3α-hydroxylated progesterone metabolites such as pregnanolone and allopregnanolone) [5] and also as a negative allosteric modulator of the GABA A-rho receptor.

Progesterone. Steroid ring system. This is a list of progestogens that are or that have been used in clinical or veterinary medicine. They are steroids and include derivatives of progesterone and testosterone.
Medrogestone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. [2] It has weak antiandrogenic , glucocorticoid , and antimineralocorticoid activity and no other important hormonal activity.
Progesterone is a progestogen, or an agonist of the nuclear progesterone receptors (PRs), the PR-A, PR-B, and PR-C. [1] In one study, progesterone showed EC 50 Tooltip half-maximal effective concentration values of 7.7 nM for the human PR-A and 8.0 nM for the human PR-B. [5] In addition to the PRs, progesterone is an agonist of the membrane progesterone receptors (mPRs), including the mPRα ...
Progesterone, via transformation into neurosteroids such as 5α-dihydroprogesterone, 5β-dihydroprogesterone, allopregnanolone, and pregnanolone (catalyzed by the enzymes 5α-and 5β-reductase and 3α- and 3β-HSD), is a positive allosteric modulator of the GABA A receptor, and is associated with a variety of effects mediated by this property ...
A selective progesterone receptor modulator (SPRM) is an agent that acts on the progesterone receptor (PR), the biological target of progestogens like progesterone.A characteristic that distinguishes such substances from full receptor agonists (e.g., progesterone, progestins) and full antagonists (e.g., aglepristone) is that their action differs in different tissues, i.e. agonist in some ...
