    摘要: Novel avermectin and milbemycin derivatives are disclosed, where the C-24 and C-25 carbon atoms are substituted by hydrogen, alkyl, alkenyl, substituted alkyl or substituted alkenyl groups. These compounds can be further substituted at the 4"-, 5-, 13-, and 23-positions. The new C-24 and C-25 substituted avermect prepared by cleavage of known and suitably protected avermectin and milbemycin compounds. The new compounds are potent anti-parasitic agents, in particular, the compounds are anthelmintic, insecticidal and acaricidal agents.

    摘要: Avermectin derivatives, wherein the C-17-21-25-dioxaspirane substructure has been modified to include substitutions of heteratomic nucleophilic thiols at the 23,24-.alpha.-epoxide. These compounds can be similarly substituted at the 4"-, 5-, 13, and 25-positions. The new C-23 and C-24 substituted avermectin derivatives are potent anthelmintic, insecticidal and acaricidal agents.
