Abstract
A series of novel 7-azaindole (1a–j) and 7-azaisatin (2a–j) derivatives were screened for their in vitro breast, lung and liver cytotoxic activities against MCF-7, A549 and HEPG2 cell lines, respectively, by MTT assay method. Among them, compounds 1h, 1i, 2h and 2i have shown good breast cytotoxic activity, and compounds 1h and 1i showed good lung cytotoxic activity and liver cytotoxic activity. These derivatives were also subjected to molecular docking study to investigate the mode of binding with the EGFR kinase, and the compounds showing similar type of docking score and binding patterns with that of the existing drug molecules such as gefitinib. 3D-QSAR studies were done using V-Life Sciences MDS 4.3 drug designing module to explain the structural requirements for the anticancer activity. Since compounds 1h and 1i exhibited high potent activity against MCF-7, A549 and HEPG2 cell lines, they could be effective epidermal growth factor receptor kinase inhibitors.
