Stanozolol
C21H32N2O (328.25145019999997)
Stanozolol is only found in individuals that have used or taken this drug. Stanozolol has is a synthetic anabolic steroid with therapeutic uses in treating hereditary angioedema. Stanozolol was first synthesized by Clinton et al. in 1959, as a heterocyclic anabolic androgenic steroid. The structure of Stanozolol differs from endogenous steroid hormones and most commercially available anabolic steroids. It most closely resembles methyl testosterone. Instead of the 3-ketogroup in methyltestosterone, there is a pyrazole ring fused to the androstane ring system. This slightly different structure has the disadvantage of making extraction and isolation of the molecule from matrices more difficult. Like most other anabolic steroids, Stanozolol has poor gas chromatographic behavior and is difficult to detect in urine, because of renal clearance and low urinary excretion. This is due to the rapid metabolization, leading to low concentration levels of the parent compound found in urine. Therefore, most research studies had focused on the detection of urinary metabolites. Androgens are drugs, derived from the natural male sex hormone testosterone, with high anabolic potential and minimized androgenic activity. It has been abused by several high profile professional athletes. Stanozolol binds to androgen receptors, such as membrane bound receptor proteins LAGS and stanozolol-binding protein (STBP). Anabolic steroids stimulate protein synthesis, resulting in an acceleration of the food conversion rate and increasing muscle growth, body mass and enhanced performance. Androgens can be used as therapeutics, because they accelerate the recovery of protein deficiency and protein-wasting disorders (e.g. osteoporosis), but they are also widely abused in doping, as well in animals as in men.

Danazol
Danazol is a synthetic steroid with anti-oestrogenic and anti progestogenic activity, and weak androgenic properties. Danazol suppresses oestrogen and progesterone receptors in the endometrium, leading to endometrial atrophy (thinning of the lining of the uterus) and reduced menstrual loss and to amenorrhoea in some women. Danazol significantly lowers the duration of menses when compared with NSAIDs and a progesterone releasing IUD; however, caused more adverse events than NSAIDs and progestogens. The use of Danazol may be limited by its side effect profile, its acceptability to women and the need for continuing treatment. Because danazol is structurally related to the anabolic steroid stanozolol, its use should be questioned. Derivatization methods and GC/MS data are used to implement danazol detection in routine screening and confirmation procedures in doping analysis. Danazol main metabolite ethisterone is excreted relatively fast in urine.

Mestranol
Mestranol is only found in individuals that have used or taken this drug. It is the 3-methyl ether of ethinyl estradiol. It must be demethylated to be biologically active. It is used as the estrogen component of many combination ORAL contraceptives. [PubChem]Mestranol is the 3-methyl ether of ethinylestradiol. Ethinylestradiol, is a synthetic derivative of estradiol. Ethinylestradiol is orally bio-active and the estrogen used in almost all modern formulations of combined oral contraceptive pills. It binds to (and activates) the estrogen receptor. Mestranol is a biologically inactive prodrug of ethinylestradiol to which it is demethylated in the liver with a conversion efficiency of 70\\%.Estrogens diffuse into their target cells and interact with a protein receptor. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Estrogens increase the hepatic synthesis of sex hormone binding globulin (SHBG), thyroid-binding globulin (TBG), and other serum proteins and suppress follicle-stimulating hormone (FSH) from the anterior pituitary. The combination of an estrogen with a progestin suppresses the hypothalamic-pituitary system, decreasing the secretion of gonadotropin-releasing hormone (GnRH).

Quinestrol
Quinestrol is only found in individuals that have used or taken this drug. It is a 3-cyclopentyl ether of ethinyl estradiol.Estrogens diffuse into their target cells and interact with a protein receptor (the estrogen receptor). Estrogen interacts with a target cell receptor. When the estrogen receptor has bound its ligand it can enter the nucleus of the target cell, and regulate gene transcription which leads to formation of messenger RNA. The mRNA interacts with ribosomes to produce specific proteins that express the effect of estradiol upon the target cell. Estrogens increase the hepatic synthesis of sex hormone binding globulin (SHBG), thyroid-binding globulin (TBG), and other serum proteins and suppress follicle-stimulating hormone (FSH) from the anterior pituitary. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary.

Desogestrel
Desogestrel is only found in individuals that have used or taken this drug. It is a synthetic progestational hormone used often as the progestogenic component of combined oral contraceptive agents. [PubChem]Binds to the progesterone and estrogen receptors. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins like desogestrel will slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH (luteinizing hormone) surge.

Estramustine
C23H31Cl2NO3 (439.16808760000004)
Estramustine is only found in individuals that have used or taken this drug. It is a nitrogen mustard linked to estradiol, usually as phosphate; used to treat prostatic neoplasms; also has radiation protective properties. [PubChem]Estramustine is a derivative of estradiol with a nitrogen mustard moiety. This gives it alkylating properties. In vivo, the nitrogen mustard component is active and can alklyate DNA and other cellular components (such as tubulin components) of rapidly dividing cells. This causes DNA strandbreaks or misscoding events. This leads to apoptosis and cell death. Also, due to the drugs estrogen component, it can bind more selectively to active estrogen receptors.

Allylestrenol
Allylestrenol is only found in individuals that have used or taken this drug. It is a synthetic steroid with progestational activity. [PubChem]Allylestrenol is similar in structure and function to progesterone. Progesterone shares the pharmacological actions of the progestins. Progesterone binds to the progesterone and estrogen receptors. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins like Progesterone will slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH (luteinizing hormone) surge. In women who have adequate endogenous estrogen, progesterone transforms a proliferative endometrium into a secretory one. Progesterone is essential for the development of decidual tissue and is necessary to increase endometrial receptivity for implantation of an embryo. Once an embryo has been implanted, progesterone acts to maintain the pregnancy. Progesterone also stimulates the growth of mammary alveolar tissue and relaxes uterine smooth muscle. It has little estrogenic and androgenic activity.

Norelgestromin
Norelgestromin is only found in individuals that have used or taken this drug. It is a drug used in contraception. Norelgestromin is the active progestin responsible for the progestational activity that occurs in women after application of ORTHO EVRA patch. Norelgestromin inhibits estrone sulfatase, which converts sulfated steroid precursors to estrogen during pregnancy. Norgelgestromin/ethinylestradiol suppresses follicular development, induces changes to the endometrium, which decreases chances of implantation and thickens the cervical mucus, impeding sperm swimming into the uterus. It also has similar agonisting binding affinities as its parent compound, Norgestimate, for progesterone and estrogen receptors. D012102 - Reproductive Control Agents > D003270 - Contraceptive Agents
2-Hydroxy-imipramine glucuronide
2-Hydroxy-imipramine glucuronide is a metabolite of imipramine. Imipramine (sold as Antideprin, Deprimin, Deprinol, Depsol, Depsonil, Dynaprin, Eupramin, Imipramil, Irmin, Janimine, Melipramin, Surplix, Tofranil), also known as melipramine, is an antidepressant medication, a tricyclic antidepressant of the dibenzazepine group. Imipramine is mainly used in the treatment of major depression and enuresis (inability to control urination). It has also been evaluated for use in panic disorder. (Wikipedia)
2-Hydroxydesogestrel
2-Hydroxydesogestrel is a metabolite of desogestrel. Desogestrel is a molecule used in hormonal contraceptives. Most combined oral contraceptive pills (COCPs, or simply OCs) on the market today contain both an estrogen compound (ethinyl estradiol is common) plus a progestin (a progesterone-like compound) such as desogestrel. Desogestrel-containing birth control pills are sometimes referred to as third generation oral contraceptives. In contrast, birth control pills that are considered second generation (Tri-Levlen, for example) contain an estrogen and a progestin, but the progestin is different, such as levonorgestrel.
