Abstract

A new class of benzimidazole derivatives bearing bis-triazole or bis-thiosemicarbazide structure was designed and synthesized as potential inhibitors of epidermal growth factor receptor (EGFR) tyrosine kinase. In vitro EGFR kinase enzyme inhibition properties were determined in comparison with erlotinib and compound (6b) containing propyl side chain at the 4th position of triazole rings showed 13.8% inhibition. Molecular docking studies were performed and docking score and binding energy were established. The most active compound formed a hydrogen bond between the Asn818 and triazole NH at the 2nd position of the benzimidazole skeleton. Predicted ADME profiles of the compounds were calculated and found to be within the appropriate reference ranges.
