[Synthesis and antiparasitic activity of arylproprenones in the nitro-5-imidazole series].

The synthesis of new arylpropenones derived from 1-methyl-5-nitro imidazole is described. The investigation of some antiprotozoal properties has shown that compounds with the groups 4-hydroxyphenyl, 4-chlorophenyl or thiophenyl have trichomonacidal activity similar to that of metronidazole.
