Abstract

The goal of this study is to find a novel class of BRCA-1 mimics for Estrogen Receptor α (ERα) breast cancer that works differently from conventional anti-estrogens. Breast Cancer Susceptibility Protein-1 (BRCA-1) is a protein was discovered to bind to ERα and decrease its function by a direct contact between regions inside BRCA1's amino terminus and the carboxy terminus of ERα. A novel class of hybrids with coumate and thiosemicarbazone scaffolds was created with the premise of developing small compounds that imitate the function of BRCA-1 to down regulate the ERα and inhibit the tumor activity of breast cancer cells. Using Schrodinger 2020-2, ADMET and in silico molecular docking tests of the proposed hybrids were performed on the BRCA-1 binding cavity of ERα. TSCO-XIV and TSCO-III are developed hybrids that have high docking scores and good binding interactions with important residues.
