Some novel imidazolyl and pyrazolylthiophenederivatives were synthesized. Different substituted N-containing heterocycles were chosen with the aim of enhancing the activity or selectivity of the products towards inhibition of one of the three isoforms of nitricoxidesynthase. One series of substances was prepared by substitution reactions of 3-bromo-2-nitrothiophene with various heterocycles. In the
