Abstract:
Breast cancer (BC) is linked to estrogen receptor alpha (ER-α) positive. Tamoxifen and other estrogen selective modulators have proven to be beneficial in slowing the progression of ER-α BC. However, tamoxifen resistance emerges as a result of long-term treatment and cancer development. Therefore, it is of interest to document data on the molecular docking analysis of phytochemicals targeting with Estrogen Receptor-alpha. The screening of the phytochemicals from the ZINC database (a total of 87133 compounds) against ER-α protein was completed. We show that ZINC69481841 and ZINC95486083bind strongly to ER- with binding energies of 10.47 and 11.88 Kcal/mol, respectively, which were significantly greater than the control compound (-8.32Kcal/mol). ZINC69481841 and ZINC95486083 were found to bind with the key residues (Leu387, Arg394, Glu353, and Thr347) of ER-α protein. Data shows that the lead compounds (ZINC69481841 and ZINC95486083) have an acceptable range of ADMET and drug-likeness properties for further consideration in drug discovery.

Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
Drug-Receptor Interactions
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue....
