Desciption:

Tamoxifen citrate(Tamoxifen, abbreviation TCT ), is an estrogen competitive antagonist and non-steroidal anti-estrogen drug. It can compete with estrogen (estradiol) to combine with estrogen receptor of breast cancer cells, inhibiting the effect of estrogen on cancer cells, and stunting growth and development of tumor cells to show anticancer effects. Clinically Tamoxifen citrate is commonly used to treat various types of breast cancer, especially for postmenopausal breast cancer women with the positive of estrogen receptor and progesterone receptor and with low prostate-specific antigen levels.

Clinical application:

1. Treatment of breast cancer.
2. Prevention of breast cancer.
3. Anti-tumor and anti-multidrug resistance.

4. Heart protection.

By reducing membrane negotiability and enhancing rigidity of inter-cell binding site, Tamoxifen citrate can reduce concentration and activity of cancer metastasis promoter and various activating enzymes, so as to inhibit or hinder growth and metastasis of cancer cell. In addition, it can promote cells surrounding tumor focus to secrete a negative growth factor - transforming growth factor TGF- G, inhibiting multiply indefinitely of cancer cells; inhibiting oxidative damage of DNA bases which is caused by hydrogen peroxide generated from human neutrophils. So except for breast cancer, it is good for treatment and prevention of other malignant neoplasms, and is used for treatment of brain tumors, liver cancer, prostate cancer, etc. In addition, Tamoxifen citrate can reduce release effect of membrane P170 glycoprotein through reducing membrane negotiability, improving intracellular effective concentration of cytotoxic drug and reducing drug resistance.

Usage And Synthesis:

Usage anti-estrogen, protein kinase C inhibitor, beneficial cardiovascular effects, bone cancer treatment, induces DNA adduct formation

(1)Breast cancer

Tamoxifen is currently used for the treatment of both early and advanced ER+ (estrogen receptor positive) breast cancer in pre- and post-menopausal women.
Additionally, it is the most common hormone treatment for male breast cancer.

(2)Infertility
Tamoxifen is used to treat infertility in women with anovulatory disorders. A dose of 10-40 mg per day is administered in days 3-7 of a woman's cycle.

(3)Gynecomastia
Tamoxifen is used to prevent estrogen-related gynecomastia, resulting from elevated estrogenic levels.

Applications:

For the treatment of advanced, recurrent breast cancer and ovarian cancer and other illnesses. Used as an antineoplastic raw materials.

Biological Activity:

Estrogen receptor antagonist/partial agonist. Selective and potent inhibitor of mammalian sterol isomerase. Neuroprotective in female rats in vivo . Also high affinity agonist at the membrane estrogen receptor GPR30.
