Fenticonazole, a new imidazole derivative with antibacterial and antifungal activity. In vitro study

The activity of alpha-(2,4-dichlorophenyl)-beta,N-imidazolylethyl 4-phenylthiobenzyl ether nitrate (fenticonazole, Rec 15/1476) compared with those of reference drugs, was tested in vitro on various bacteria and fungi. This compound showed in vitro an excellent activity against gram-positive Microorganisms. The Antifungal activity spectrum is very broad: dermatophytes, yeasts and dimorphic fungi were the most susceptible organisms. Fenticonazole showed in vitro at pH range 4-5 the highest activity against yeasts. The addition of inactivated bovine serum to the culture medium led to a slight decrease in activity of all the tested substances.
