Synthesis, antimicrobial and genotoxic properties of some benzoimidazole derivatives. 
A number of 1H-benzoimidazol-2-ylamine and of 1-methyl-1H-benzoimidazol-2-ylamine derivatives were synthesized and the crystal and molecular structure of N-[4-(2-amino-benzoimidazole-1-sulfonyl)-phenyl] acetamide was determined by X-ray diffraction analysis.  The compounds obtained were investigated for antimicrobial and genotoxic activities.
