  • Title: [Synthesis of new diheterocyclic derivatives of imidazole with antiparasitic activity].
    Author: Quattara L, Debaert M, Cavier R.
    Journal: Farmaco Sci; 1987 May; 42(5):383-96. PubMed ID: 2886364.
    Abstract:
    A description is given of potential cyclic imidazoles such as 3,3-dichloro-2-methylenimino-acrylonitrile derived from nitro or non-nitro heterocycles, as well as the hydrazone, semicarbazone and arylpropenone derivatives of the 4-chloro-2-(5-nitro-2-thienyl) (V), 5-imidazole carboxaldehyde (IV) and the 5-bromothienyl analogue. The antiparasitic activity was tested in vitro against Trichomonas vaginalis and Entameba histolytica. Some of the nitro containing compounds showed trichomonacidal activity whereas one of the non-nitro compounds with potential imidazole structure showed clear amebacidal activity. This compound, 3,3-dichloro-2-methyleneimino acrylonitrile has anti-ameba activity comparable with that of metronidazole.
