A number of nucleoside analogues have been synthesized and evaluated for their antibacterial and antifungal activities against Staphylococcus aureus, Group D Streptococcus, Pseudomonas aeruginosa, Proteus spp., Salmonella spp., Aspergillus fumigatus, Penicillium marneffei, Candida albicans, Cryptococcus neoformans, and Mucor spp. The compounds 1, 4, and 6 emerged as potent antibacterial agents with MIC values of 0.75, 0.38, and 0.19 microM, respectively, against group D Streptococcus. Further, the results suggest that the molecules 4, 6, and 7 would be potent antifungal agents as they show substantial degree of inhibition toward the growth of pathogenic fungi with MICs of 0.75, 0.38, and 0.38 microM, respectively.
