Design of balanced dual-target inhibitors of EGFR and microtubule.

Motivated by the clinical success of combining tyrosine kinase inhibitors with microtubule-targeted drugs in antitumor treatment, this paper presents a novel combi-targeting design for dual-target inhibitors, featuring arylformylurea-coupled quinazoline backbones. A series of target compounds (10a-10r) were designed, synthesized, and characterized. Biological assessments demonstrated that 10c notably potentiated ten tumor cell lines in vitro, with IC values ranging from 1.
