title: Synthesis and biological activity of pyrimido[2,1-b][1,3]thiazine, [1,3]thiazino[3,2-a]purine and [1,2,3]triazolo[4,5-d][1,3]thiazino[3,2-a]pyrimidine derivatives and thiazole analogues.
abstract: Some series of thiazolo[3,2-a]pyrimidine, pyrimido[2,1-b] [1,3]thiazine, thiazolo[3,2-a]purine, [1,3]thiazino[3,2-a]purine, thiazolo[3,2-a][1,2,3]triazolo[4,5-d]pyrimidine and [1,2,3]triazolo[4,5-d][1,3]thiazino[3,2-a]pyrimidine derivatives, variously functionalized, were prepared. The compounds were tested for antimicrobial and antimycotic activity on a number of strains, namely: E. coli, Proteus vulgaris, P. mirabilis, Pseudomonas aeruginosa, Salmonella sp., Staphylococcus aureus, S. faecalis, Bacillus subtilis, Sarcina lutea, Candida albicans, C. tropicalis, Aspergillus sp., and for antiviral activity on Herpes simplex virus Type 1, Vesicular stomatitis virus and Coxsackievirus B5. The compounds proved to be devoid of activity against viruses and gram-negative bacteria, while some of them exhibited modest activity against gram-positive bacterial strains.
