    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 avermectin and milbemycin derivatives are 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: There are disclosed synthetic derivatives of the natural product paraherquamide. The synthetic derivatives are prepared by reactions at the parahe­quamide A, B, E, F and G rings, that is at carbon atoms 14 to 16, the lactam ring and carbon atoms 24 to 26 as well as carbon atoms 5 and 12. The compounds are active antiparasitic agents and compositions for that use are also disclosed.

    摘要: Novel avermectin and milbemycin compounds, wherein at least one of the 4a, 5 or 4˝ positions are substituted with a fluoro groups, are prepared by replacement of hydroxy or other suitable leaving group of avermectin and milbemycin compounds with fluorine. The fluoroavermectin and fluoromilbemycin compounds have utility as anti-parasitic agents and as highly potent insecticides against agricultural pests.

    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.
