An iminodiacetic acid (IDA) derivative of 2-methyl-5-nitroimidazole was synthesized as a carrier molecule for radiolabeling with the gamma emitting radioisotope, 99mTc, for imaging hypoxic regions of tumors. The ligand was synthesized in excellent yield and labeled using freshly prepared [99mTc(CO)3(H2O)3]+

An unidentified metabolite of dimetridazole (DMZ), found in pig plasma, muscle and kidney, was shown by chromatography and spectroscopy to be 2-methyl-5-nitroimidazole (2-MNI), resulting from N-demethylation of DMZ. This route of degradation competes with the oxidation pathway previously described. The

To study the synthesis and antibacterial activity of ciprofloxacin derivatives. Ciprofloxacin derivatives were synthesized primarily from 2-methyl-5-nitroimidazol and ciprofloxacin through nucleophilic substitution. The antibacterial activity of the synthesized compounds were tested. Nine new compounds were synthesized. The structure of the

1,8-Diazabicyclo[5.4.0]undec-7-ene salts of 2-methyl-4(5)-nitroimidazole or benzotriazole were obtained in crystalline form. Michael-type addition of these salts to (4S,5R)-(E)-4,6-di-O-acetyl-5-hydroxy-2-hexenal gave, after acetylation of the product, an isomeric mixture of acetylated 3-(azol-1-yl)-2,3-dideoxy-D-arabino-hexopyranosides and 3-(azol-1-yl)-2,3-dideoxy-D-ribo-hexofuranosides. Reaction of these peracetylated adducts with trimethylsilylated thymine
