    摘要: Avermectin compounds are substituted at the 4a-position: the 4a-methyl group is first derivatized with a hydroxy group which is then substituted with a variety of alkyl, alkoxy alkyl, or polyalkoxy alkyl groups and derivatives thereof. The compounds are potent antiparasitic and anthelmintic agents and compositions for such uses are also disclosed.
