Abstract
Breast cancer is the leading cause of death in Brazil and worldwide. Triple negative breast cancer (TNBC), which does not express hormone receptors, comprises 20% of the breast cancer cases and presents relapses within 3 years, approximately. However, the major cause of death in cancer is due the formation of metastases. TNBC has a high incidence of lung and brain metastases. Moreover, few treatments are available for these patients, due to the lack of target therapies in this type of cancer as in tumors that express hormone receptors. Search and development of new treatments for TNBC with fewer side effects, more effective and with less resistance are important to treat this disease. Natural products are rich sources of molecules with antimetastatic and antitumoral activities. Among these molecules are the gingerols, from ginger. Natural products are also known to have chemosensitizing and radiosensitizing effects, resulting in a better treatment efficacy with fewer side effects. Previous results from our research group showed that among gingerols, [6]-, [8]- and [10]-gingerol, the latter is the molecule with the best antiproliferative activity in breast tumor cells with fewer effects on normal cells, human fibroblasts, indicating a selectivity for tumor cells. Furthermore, [10]-gingerol has an antitumoral activity, reducing primary tumor size in vivo, and also an antimetastatic activity, reducing lung, bones and brain metastases. Therefore, the aim of this project is to investigate structural modifications of [10]-gingerol (10GM) molecule to improve its activity and to verify its chemosensitizing effect in a combinatorial treatment with doxorubicin using an animal breast cancer spontaneous metastasis model.
