In-silico Drug Design, ADMET Screening, MM-GBSA Binding Free Energy of Some Chalcone Substituted 9-Anilinoacridines as HER2 Inhibitors for Breast Cancer

Due to their DNA-intercalating agents 9-aniliinoacridines play an important role as antitumor agents. A Series of some Chalcone substituted 9-aniliinoacridines 1a-x were designed for their anti-breast cancer activity. Molecular docking studies were performed by Glide module of Schrodinger suite-2016, targeted against Human epidermal growth factor receptor HER2 (PDB id-3PP0). In-silico ADMET screening by qikprop module and binding free energy by Prime-MMGBSA module also performed. Based on the binding affinity of the designed molecules with HER2 on the basis of GLIDE score and interaction patterns. Most of the compounds 1a-x have significant Glide scores when compared with standard anticancer drugs ledacrine and tamoxifen. Most of the Chalcone substituted 9-anilinoacridine derivatives 1a-x have good binding affinity with Glide score in the range of -5. 32 to -9.37 compared with the standard ledacrine (-5.23) and tamoxifen (-3.78). The results reveals that, Chalcone substituted 9-amino acridines as HER2 inhibitor and the compounds, 1g, f, b, h, t, u with good Glide score may produce significant anti-breast cancer activity for further refinement.
