Abstract: Molecular docking is an important tool for connecting molecular biological structure to computer-aided drug design. The purpose of this blind docking experiment is to compare the binding energies of these three drugs and to predict the most likely binding poses of a ligand with a known three dimensional structure of a protein. To substantiate our previous in vitro study findings, an in silico model was chosen to compare the binding properties of the three drugs. The work is entirely bioinformatics in nature. Blind docking was accomplished with the help of free software/(s). A comparison was made among the three drgus, used primarily in cancer treatment, namely, anastrazole, capecitabine and quercetin. In our in vitro study, these three drugs were extremely effective. CB dock-2 to blind dock, SwissTargetPrediction to choose the targets, PubChem and Protein Data Base to obtain 3D structures of ligand and target respectively were used. Absorption, Distribution, Metabolism, and Excretion (ADME) from SwissADME, drug likeness from MolSoft L.L.C. software, and Liponski’s rule was used to check the “Rule of five (RO5)”. The crystallographic structures have resolution values ranging from 1 Å to 3 Å. Lipinski’s rule of five, Swiss ADME and drug likeness were used to compare the three drugs. For all of the targets studied, quecetin appeared to have the highest AutoDock vina scores. To summarize the current findings and publicly available data, quercetin is chemoprotective and radioprotective to healthy/ normal cells and it can be used during cancer treatment.
