  Substituted imidazo[1,2-a]pyridine-2-carbamate anthelmintics

  摘要：

  Anthelmintic efficacies of a series of 6-substituted methyl imidazo[1,2-alpha]pyridine-2-carbamates were compared to similarly substituted benzimidazole-2-carbamates. With only one exception, methyl 6-benzoylimidazo[1,2-alpha]pyridine-2-carbamate, both classes of compounds exhibited similar activity vs. Nematospiroides dubius in mice. Preliminary screening indicated methyl 6-(1,2,2-trichloroethenyl)imidazo[1,2-alpha]pyridine-2-carbamate to be the most potent derivative in the series. However, evaluation in sheep indicated that its anthelmintic spectrum was inferior to methyl 6-(phenylsulfinyl)imidazo[1,2-alpha]pyridine-2-carbamate.
