Design, synthesis and anticancer evaluation of structurally modified substituted aryl-quinazoline derivatives as anticancer agents

This is the authors' abstract. We don't add key points for this paper.

A new library of structurally modified aryl quinazoline-isoxazole (12a–j) derivatives have been designed, synthesized and characterized by 1HNMR, 13CNMR and mass spectral data. Further these compounds were evaluated for anticancer applications against four human cancer cell lines including PC3, DU-145 (prostate cancer), A549 (lung cancer) and MCF-7 (breast cancer) by utilizing the MTT assay. The results were compared with etoposide which was used as positive control. Most of the compounds showed good to moderate anticancer activities against the four cancer cell lines. Among them, compounds 12a, 12b, 12c, 12d and 12j exhibited more potent activities. Further, molecular docking studies were carried out for all synthesized compounds against the cancer targets Selective Human Androgen Receptor (PDB ID: 3V49) and Abl-Tyrosine kinase (PDB ID: 1IEP). All the docked ligands have exhibited good binding interactions with the targeted protein.
