The imidazol and imidazoline derives have many advantages in therapy. For the synthesis of new imidazoline derives, the authors implemented the ethylene diamene cyclization from nitril compounds differently substituted. Then, a dehydrogenation of these imidazolines leaded to the imidazol derives. The last reaction consisted of the condensation of these imidazolines and imidazoles. The authors subjected their synthesized products to an ophthalmic protective evaluation (anti-oedema, secondary anti-hyperemia) on the experimental ocular irritancy models
