3-aryl-6-substituted thiazolopyrimidin-2(3H)-thionederivatives 4 and 6 have been synthesized by reacting thiazolopyrimidines 2 with ω -bromoacetophenone 3 and 2-chloro-N-(2-thiazolyl)acetamides 5 . The structure elucidation of the obtained compounds was performed by IR, 1 H-NMR, MASS spectroscopy, and elemental analyses. The antibacterial and antifungal activities of the compounds were investigated, and
Some thiazolo[4,5-d]pyrimidines were prepared in order to investigate their antimicrobial activity. A significant inhibitory effect was recorded for many compounds against Staphylococcus aureus ATCC 25923 (3, 6, 9a; MIC = 10-20 mug/ml), Escherichia coli ATCC 25922 (3,5,9b, MIC = 40 mug/ml) and Candida albicans DSM 70443 (6, MIC = 50 mug/ml).
