Syntheses of 4-(indole-3-yl)quinazolines – A new class of epidermal growth factor receptor tyrosine kinase inhibitors

The epidermal growth factor (EGF) family of membrane receptors has been identified as a key element in the complex signaling network that is utilized by various classes of cell–surface receptors. The synthesis and pharmacological results of 4-(indole-3-yl)quinazolines are described. The synthesized compounds are new high potent EGFR-tyrosine kinase inhibitors with excellent cytotoxic properties at different cell lines. Furthermore the 4-(indole-3-yl)quinazolines show some tendencies to inhibit the HER-2 TK, too. Moreover this substance class has remarkable strong fluorescence properties.
