Chlorotrianisene is a long-acting, orally bioactive non-steroidal synthetic estrogen that was used for the treatment of menopause, deficiencies in ovary function, and prostate cancer.
| ln Vitro |
Initial evidence of the potential for ER activation as a growth-stimulating mechanism is provided by comparing the intracellular estrogen receptor (ER) affinity of chlortrianisene with the comparable rat uterine cytosolic ER affinity. With a 500 nM Ki and an EC50 of 28 nM, chlorotrianisene stimulates cell proliferation in MCF-7 cells in a concentration-dependent manner[1].

| ln Vivo |
Rat liver microsomes and NADPH were incubated with chlortrianisene to produce reaction intermediates that covalently bound to the protein. The uterine estrogen receptor may be rendered inactive by intermediates (ER). Under conditions that resulted in intermediates, the ER binding capacity for [3H]estradiol (E2) was significantly reduced when chlorotrianisene was incubated with rat liver microsomes and NADPH in the presence of a rat uterus [3].

Absorption, Distribution and Excretion
Absorption following oral administration is rapid. ...LONG-ACTING...BECAUSE OF SEQUESTRATION IN ADIPOSE TISSUE &, THEREFORE, IS NOT WIDELY USED. ...SUGGESTS THAT DRUG IS CONVERTED IN LIVER TO MORE ACTIVE FORM. ... IT IS STORED IN FAT, FROM WHICH IT IS SLOWLY RELEASED TO GIVE SUSTAINED ACTION. ESTROGENIC ACTIVITY HAS BEEN FOUND IN ADIPOSE TISSUE UP TO MONTH AFTER CESSATION OF THERAPY. Metabolism / Metabolites Metabolized principally in the liver, although the kidneys, gonads, and muscle tissues may be involved to some extent. The metabolic fate of the synthetic estrogens has not been fully elucidated. RATE OF O-DEMETHYLATION WAS MAXIMAL AT 0.4 MMOLAR NADPH. ALTHOUGH NADH DID NOT CATALYZE REACTION ALONE, IT HAD SYNERGISTIC EFFECT IN PRESENCE OF EQUIMOLAR AMT OF NADPH. EXTRACTS FROM INCUBATION MIXT CONTAINED 1 MAJOR (MONO-O-DEMETHYLATED) & A MINOR (BIS-O-DEMETHYLATED) METAB. |

Small white crystals or white powder. Softens at 226 °F. Odorless. (NTP, 1992) Chlorotrianisene is a chloroalkene. It has a role as an estrogen receptor modulator, an antineoplastic agent and a xenoestrogen. It derives from a hydride of a stilbene. Chlorotrianisene is an orally bioavailable, highly lipophilic, synthetic triphenylethylene (TPE) derivative and selective estrogen receptor modulator (SERM), with predominantly estrogenic but also antiestrogenic activities. Upon administration, chlorotrianisene binds to estrogen receptors (ER) and, depending on the responsive target cells, either activates or blocks ER activity. This modulates the expression of ER-responsive genes in a tissue-specific manner. This agent may increase bone mineral density, modify the lipid profile and ameliorate vasomotor symptoms. Chlorotrianisene inhibits the pituitary secretion of the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH) through a negative feedback mechanism. A powerful synthetic, non-steroidal estrogen. Drug Indication Used to treat symptoms of menopause, deficiencies in ovary function (including underdevelopment of female sexual characteristics and some types of infertility), and in rare cases, prostate cancer. Chlorotrianisene may also be used to prevent breast engorgement following childbirth. Mechanism of Action Chlorotrianisene binds to the estrogen receptor on various estrogen receptor bearing cells. Target cells include cells in 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. |

| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (6.56 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.56 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
