Usage And Synthesis
Tamoxifen is non-steroidal anti-estrogen drugs. Its structure is similar to estrogen, existing Z type and O type isomers. The physical and chemical properties are different from each other, and physiological activity is different. E type has weak estrogenic activity, Z type having the effect of anti-estrogen. If the estrogen receptor (ER) is present in breast cancer cells, estrogen enters into tumor cells and binds with ER, promoting mRNA and DNA synthesis of tumor cells, stimulating tumor cell growth. However, Tamoxifen Z isomer enters into the cell, competitively binding with ER to form receptor complexes, inhibiting that estrogen plays an role, and inhibiting proliferation of breast cancer cells. Clinically it is mainly used for high levels of estrogen in breast cancer patients, which combines with androgen and other anticancer drugs (such as doxorubicin, etc., enhancing the effectiveness and showing good effect in postmenopausal patients with advanced breast cancer.
