A series of methyl 2-(2-(2-arylquinazolin-4-yl)sulfanyl)acetylamino alkanoates have been developed on the basis of the S-chemoselective reaction of 2-arylquinazolin-4(3H)-thione with ethyl chloroacetate and N,N′-dicyclohexylcarbodiimide coupling method with amino acid ester hydrochloride. The precursor 2-arylquinazolin-4(3H)-thione was prepared by a new thiation method from 2-arylquinazolin-4(3H)-one by a two-step reaction that includes chlorination and then the reaction with N-cyclohexyldithiocarbamate cyclohexyl ammonium salt. The antimicrobial activity of the synthesized compounds was tested in vitro via paper-disc agar-plate method against two bacterial strains Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria Escherichia coli and a pathogenic yeast Candida albicans. Most synthesized compounds showed remarkable antibacterial activity against E.?coli overpassing the standard reference antibiotics applied: tetracycline, erythromycin, and novobiocin. On the other hand, most synthesized compounds gave moderate antifungal activity against pathogenic yeast C.?albicans.
