Synthesis and cytotoxic activity of (2-arylquinazolin-4-yl)hydrazones of 2-hydroxybenzaldehydes

2-Phenyl-6,7-difluoro and 2-(4-fluorophenyl)quinazoline derivatives bearing salicylidenhydrazino fragments at position 4 were prepared based on 4,5-difluoroantranilic acid or anthranilamide. Molecular docking to casein kinase 2 was performed; compounds with high in silico activity to CK2 were revealed. Cytotoxic activity of the synthesized compounds was studied on cancer cell line MDA-MB-231 and normal cell line WI26 VA4
