| New drugs targeted therapy in breast cancer |
Lapatinib is developed by the British company GlaxoSmithKline,it is a breast cancer targeted therapy drug,it is a tyrosine kinase inhibitor, which can inhibit the human epidermal growth factor receptor -1 (ErbB1) and human epidermal growth factor receptor -2 (ErbB2) tyrosine kinase activity. It is unique because it can play a role in a variety of ways, so that the breast cancer cells can not receive the desired signal for the growth . The mechanism is inhibiting the ATP site of intracellular EGFR(ErbB-1) and HER2 (ErbB-2) to prevent phosphorylation and activation of tumor cells, blocking down signal by EGFR (ErbB-1) and homogenous HER2 (ErbB-1) and its heterodimer. Breast cancer molecular targeted therapy aims at the occurrence and development of cancer-related genes and their expression products of breast cancer for treatment. Molecular targeted drugs by blocking signal transduction of tumor cells or associated cells , control changes in cell gene expression, in order to inhibit or kill tumor cells. March 14, 2007, the US Food and Drug Administration approved lapatinib in combination with Xeloda (capecitabine) for the treatment of human epidermal factor receptor 2 (ErbB2) overexpression and treated by anthracyclines, paclitaxel and trastuzumab patients with advanced or metastatic breast cancer. Clinical trials have shown that for those HER2 type breast cancer patients who are resistant to Roche's Herceptin , the product also has very good clinical results. Lapatinib is a novel targeted anti-cancer drug. It Can act on Her-1 and Her-2 two targets at he same time, the biological effect of the inhibition of tumor cell proliferation and growth arising from this mode of action is much larger than acting on just one target. The so-called targeted therapy, refers to certain receptors, genes or proteins as a key target, and then targets to kill tumor cells related to drugs. Human ErbB receptors belong to the type I receptor tyrosine kinase (TK) family. It includes ErbB1 (EGFR), ErbB2 (HER2), ErbB3 (HER3), and ErbB4 (HER4). Cancer patients ErbB-1 (EGFR) and ErbB-2 (HER-2) receptors are usually over-expressed or other changes occur on them. Currently known human epidermal growth factor receptor -2 (ErbB-2, HER-2) is a clearer understanding human cancer gene which is closely related to breast cancer .its highly expression in breast cancer often precedes that it is easy to metastasize to lymph nodes and it is poorly differentiated , its prognosis is not good. With the in-depth study of HER-2 , it has become one target molecule of the breast cancer-specific therapy. The above information is edited by the Chemicalbook of Tian Ye. |
