A series of 2,4-disubstituted quinazoline derivatives was designed and synthesized as multi-target therapeutic agents that may act as anti-cancer and antimicrobial agents. The target compounds were evaluated for primary anti-cancer activity followed by EGFR inhibition assay for most potent compounds. Compounds 6 and 8c exhibited good EGFR inhibition activity with IC50 values of 0.201 and 0.405 µM,...
