Anti-Breast Cancer Compound Library

2,667 compounds

Breast cancer is the most frequent cancer among women, impacting 2.1 million women each year, and also causes the greatest number of cancer-related deaths among women. Surgery is usually the first type of treatment for breast cancer, which is usually followed by chemotherapy or radiotherapy or, in some cases, hormone or targeted therapies, especially for metastatic breast cancer (MBC).

Breast cancer is a heterogeneous disease, which is categorized into 3 major subtypes based on the presence or absence of molecular markers for estrogen or progesterone receptors and human epidermal growth factor 2 (ERBB2; formerly HER2): hormone receptor positive/ERBB2 negative (70% of patients), ERBB2 positive (15%-20%), and triple-negative (tumors lacking all 3 standard molecular markers; 15%). Different intrinsic subtypes exhibit different tumor behavior with different prognoses, and may require specific targeted therapies to maximize treatment effectiveness. Otherwise, some signaling pathways also play important roles in the development of breast cancer, such as NF-κB Signaling Pathway, TGF-beta Signaling Pathway, PI3K/AKT/mTOR signaling pathway and Notch Signaling Pathway. These signaling pathways offer ideal targets for development of new targeted therapies for breast cancer.

MCE supplies a unique collection of 2,667 compounds with identified and potential anti-breast cancer activity. MCE Anti-Breast Cancer Compound Library is a useful tool for anti-breast cancer drugs screening.
