Four new 2'-deoxynucleosides of benzimidazole derivatives were prepared. An
timicrobial activity of many indazole, benzotriazole, benzimidazole derivat
ives and their nucleosides were tested by the agar diffusion method. Among
the investigated compounds, dinitro- and trifluoromethyl-substituted benzim
idazoles and their nucleosides were the most potent.
