2-Methoxyestrone
2-Methoxyestrone (or 2-ME1) belongs to the class of organic compounds known as estrogens and derivatives. These are steroids with a structure containing a 3-hydroxylated estrane. Thus, 2-methoxyestrone is considered to be a steroid or steroid derivative. It is a by-product of estrone and 2-hydroxyestrone metabolism and has been detected in all mammals. More specifically, 2-methoxyestrone is an endogenous, naturally occurring methoxylated catechol estrogen and a metabolite of estrone that is formed by catechol O-methyltransferase via the intermediate 2-hydroxyestrone. 2-Methoxyestrone is part of the androgen and estrogen metabolic pathway. The acid ionization constant (pKa) of 2-methoxyestrone has been determined to be 10.81 (PMID: 516114). 2-Methoxyestrone can be metabolized to a sulfated derivative (2-methoxyestrone 3-sulfate) via steroid sulfotransferase (EC 2.8.2.15). It can also be glucuronidated to 2-methoxyestrone 3-glucuronide by UDP glucuronosyltransferase (EC 2.4.1.17). Unlike estrone but similarly to 2-hydroxyestrone and 2-methoxyestradiol, 2-methoxyestrone has very low affinity for the estrogen receptor and lacks significant estrogenic activity (PMID: 10865186). 2-methoxyestrone is a steroid derivative that is a byproduct of estrone and 2-hydroxyestrone metabolism. It is part of the androgen and estrogen metabolic pathway. The acid ionization constant (pKa) of 2-methoxyestrone is 10.81 (PMID: 516114). 2-Methoxyestrone can be metabolized to a sulfated derivative (2-Methoxyestrone 3-sulfate) via steroid sulfotransferase (EC 2.8.2.15).

Adrenosterone
Adrenosterone is a steroid hormone with weak androgenic effect. It was first isolated in 1936 from the adrenal cortex by Tadeus Reichstein at the Pharmaceutical Institute in the University of Basel. Originally, adrenosterone was called Reichsteins substance G.(Wikipedia). Andrenosterone is created from androst-4-ene-3,17-dione by the work of two enzymes, CYP11B (E1.14.15.4) and 11beta-hydroxysteroid dehydrogenase [EC:1.1.1.146]. Adrenosterone is a steroid hormone with weak androgenic effect. It was first isolated in 1936 from the adrenal cortex by Tadeus Reichstein at the Pharmaceutical Institute in the University of Basel. Originally, adrenosterone was called Reichsteins substance G. Adrenosterone ((+)-Adrenosterone) is a competitive hydroxysteroid (11-beta) dehydrogenase 1 (HSD11β1) inhibitor. Adrenosterone is a steroid hormone with weak androgenic effect. Adrenosterone is a dietary supplement that can decrease fat and increase muscle mass. Adrenosterone acts as a suppressor of metastatic progression of human cancer cells[1][2][3].
Testolactone
Testolactone is only found in individuals that have used or taken this drug. It is an antineoplastic agent that is a derivative of progesterone and used to treat advanced breast cancer. [PubChem]Although the precise mechanism by which testolactone produces its clinical antineoplastic effects has not been established, its principal action is reported to be inhibition of steroid aromatase activity and consequent reduction in estrone synthesis from adrenal androstenedione, the major source of estrogen in postmenopausal women. Based on in vitro studies, the aromatase inhibition may be noncompetitive and irreversible. This phenomenon may account for the persistence of testolactones effect on estrogen synthesis after drug withdrawal.

19-Oxoandrost-4-ene-3,17-dione is an intermediate in Androgen and estrogen metabolism. 19-Oxoandrost-4-ene-3,17-dione is the 4th to last step in the synthesis of 2-Methoxyestrone 3-glucuronide. It is generated from 19-Hydroxyandrost-4-ene-3,17-dione and then converted to Estrone.

2-Hydroxy-3-methoxyestrone
2-Hydroxy-3-methoxyestrone is obtained after methylation of 2-Hydroxyestrone and is generally found in the urine as an excretion product. 2-hydroxyestrone is the result of the hydroxylation of estrone E1. The hydroxylation process helps to clear out E1 from the body. This is critical because higher lifetime exposure to estrogen has been found to increase cancer risks to the reproductive system, especially to the breast. However, 2-hydroxyestrone has a weak estrogenic activity and breast cancer risks are quite low in women with high urinary excretion of 2-hydroxyestrone. 2-Hydroxy-3-methoxyestrone levels in urine could be an indicator to help assess the risk factors for development of breast cancers. DG(14:1(9Z)/22:4(7Z,10Z,13Z,16Z)/0:0) belongs to the family of Diacylglycerols. These are glycerolipids lipids containing a common glycerol backbone to which at least one fatty acyl group is esterified. DG(14:1(9Z)/22:4(7Z,10Z,13Z,16Z)/0:0) is also a substrate of diacylglycerol kinase. It is involved in the phospholipid metabolic pathway.
4-Methoxyestrone
Thyrotropin-releasing hormone (TRH), also called thyrotropin-releasing factor (TRF), thyroliberin or protirelin, is a tripeptide hormone that stimulates the release of thyroid-stimulating hormone and prolactin by the anterior pituitary. In humans, it also acts as a prolactin-releasing factor. It is also a neurotransmitter in the central nervous system. TRH is produced by the hypothalamus and travels across the median eminence to the pituitary via the hypophyseal portal system. In addition to the brain, TRH can also be detected in other areas of the body including the gastrointestinal system and pancreatic islets. Medical preparations of TRH are used in diagnostic tests of thyroid disorders and in acromegaly. [HMDB] This compound belongs to the family of Ketosteroids. These are steroid derivatives comprising a ketone group attached to steroid skeleton.
