yellow crystalline powder | [Uses]
5-Nitro-2-furoic acid was used in the preparation of [1,2,4]triazolo[3,4-b][1,3,4]thiadiazines and [1,2,4]triazolo[3,4-b][1,3,4] thiadiazoles. | [Uses]
5-Nitro-2-furoic acid is a representative of 2-substituted
5-nitrofurans. A number of nitrofurans have been used as
antibacterial, antiprotozoal, and anthelmintic drugs in
humans and animals. 2-Substituted 5-nitrofurans have been
used worldwide as human and veterinary medicines, food
preservatives, and feed additives, and they are utilized in
human medicine as antibacterial agents. Therefore, the relationship
between the antibacterial effect and the mutagenicity
of these compounds and their oxidized metabolites is
important. Comparison of the antibacterial effects and genotoxic
potencies of nitrofuran drugs and their oxidative
metabolites may provide a new direction for selecting nitrofuran
drugs for human use. | [Uses]
