Certain novel substituted imidazo [1,2-a] pyridines with a substituted amino group at the 2- or 3- position and a heterocyclic moiety on the pyrido portion of the molecule are active anthelmintic agents. The heterocyclic moiety is connected to the imidazo [1,2-a] pyridine molecule through an oxygen, sulfur, sulfinyl or sulfone. The novel compounds are prepared from the appropriately substituted 2-amino pyridine precursor. Compositions which utilize said novel imidazo [1,2-a] pyridines as the active ingredient thereof for the treatment of helminthiasis are also disclosed.
具有取代氨基团的新型取代咪唑[1,2-a]吡啶,其在2-或3-位置上具有取代基,并且在分子的吡啶部分上具有杂环基团,是活性驱虫剂。杂环基团通过氧、硫、亚磺酰或磺酰连接到咪唑[1,2-a]吡啶分子上。这些新型化合物是由适当取代的2-氨基吡啶前体制备而成。同时,本文还公开了利用这些新型咪唑[1,2-a]吡啶作为活性成分的组合物,用于治疗蠕虫病。
