Synthesis and antimicrobial evaluation of substituted 5,6-dihydro-5-nitrouracils

Abstract
Reaction of 5-nitrouracil derivatives with sodium borohydride in methanol-water, followed by neutralizaiton of the product with acid, produced 5,6-dihydro-5-nitrouracil, 5,6-dihydro-6-methyl-5-nitrouracil, 5,6-dihydro-5-nitro-1-(4-nitrophenyl)uracil and 5,6-dihydro-5-nitro-1-(.beta.-D-ribofuranuronic acid ethyl ester)uracil. In assays for antimicrobial activity using strains of Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans and Trichophyton mentagrophytes, significant inhibition of growth was not found.
