    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.
