    摘要: Avermectin derivatives are disclosed which incorporate two fluorine atoms at the 4' monosaccharide position, the 4" disaccharide position or the 23 position. Avermectin aglycone derivatives are also disclosed which incorporate two fluorine atoms at position 13 or 23. These difluoro avermectin analogs are derived from corresponding ketones and enones which in turn are prepared by chemical modification of naturally occurring avermectins. These compounds are used as antiparisitic, insecticidal and antihelmintic agents in humans and animals and compositions containing such compounds as the active ingredient thereof are also disclosed.

    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: There are disclosed novel avermectin .DELTA. 23,24-derivatives (also referred to as 23,24-dehydro compounds). The compounds are prepared by selective dehydration of avermectin A2 or B2 compounds. The avermectin compounds have utility as anti-parasitic agents and compositions for that use are also disclosed. The compounds are also highly potent insecticides against agricultural pests. The .DELTA. 23,24-avermectin compounds have increased activity relative to the A2 or B2 compounds.
