Abstract

New heterocyclic compounds spiroderivatives of allopurinol of biological interest were prepared from allopurinol via thionation and 1,3-dipolar cycloaddition and were produced in high to excellent yields. These compounds were characterized on the basis of spectral and spectroscopic data

H NMR,

C, IR, and MS. The antibacterial activity of the synthesized products was studied using bacterial strains: Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, and Pseudomonas aeruginosa. Compounds having an ethyl group showed the best activity with MIC value of 31.25 µg-mL against Staphylococcus aureus and Streptococcus fasciens.
