Molecular modeling based approach, synthesis, and cytotoxic activity of novel benzoin derivatives targeting phosphoinostide 3-kinase (PI3Kα)
摘要:
The oncogenic potential of phosphatidylinositol 3-kinase (PI3K alpha) has made it an attractive target for anticancer drug design. In this work, we describe our efforts to optimize the lead PI3K alpha inhibitor 2-hydroxy-1,2-diphenylethanone (benzoin). A series of 2-oxo-1,2-diphenylethyl benzoate analogs were identified as potential PI3K alpha inhibitors. Docking studies confirmed that the aromatic interaction is mediating ligand/protein complex formation and identified Lys802 and Val851 as H-bonding key residues. Our biological data in human colon carcinoma HCT116 showed that the structure analogs inhibited cell proliferation and induced apoptosis. (C) 2015 Elsevier Ltd. All rights reserved.
