含苯并噻唑的硫脲嘧啶衍生物的合成及抗菌活性评价

Abstract

A series of unreported thiouracil derivatives 7 containing a benzothiazole moiety were synthesized by the reaction of 4-oxo-6-phenyl-2-thioxo-1,2,3,4-tetrahydro-pyrimidine-5-carbonitrile (6) with N-(benzo[d]thiazol-2-yl)-4-(chloromethyl)-benzamide (5), which was prepared from the amidation of 2-aminobenzothiazole and 4-(chloromethyl)benzoyl chloride. The newly synthesized compounds 7 were characterized by IR, MS, NMR, and element analysis. All the compounds were evaluated for their antibacterial activities against Bacillus amyloliquefaciens, Staphylococcus aureus and Bacillus subtilis. The results of the 24-hour antibacterial test showed that some compounds had good inhibitory activities against the three tested strains. Show more
