    • The present invention relates to novel 23-oxo (keto) and 23-imino derivatives of certain C(26,27)-epoxy- and C(14,15;26,27)-diepoxy-LL-F28249 compounds. The LL-F28249 compounds (collectively) are isolates from the fermentation broth of Streptomyces cyaneogriseus subspecies noncyanogenus having deposit accession no. NRRL-15773. The derivatives are obtained by oxidation of the 23-hydroxy group of 5-O-silylated-C(26,27)-epoxy and C(14,15;26,27)diepoxy-LL-F28249 compounds, followed by desilylation and derivatization with amino compounds. The novel compounds have anthelmintic, ectoparasiticidal, nematicidal, insecticidal and acaricidal activity and are, therefore, useful in the treatment of infections in warm-blooded animals and infestations in agricultural crops. Compositions containing the present compounds as active ingredients thereof also are presented.
    • 本发明涉及某些C(26,27) - 环氧 - 和C(14,15; 26,27) - 二环氧-LL-F28249化合物的新型23-氧代(酮)和23-亚氨基衍生物。 LL-F28249化合物(共同)是具有存放登记号的非花青素Streptomyces cyaneogriseus亚种的发酵液的分离物。 NRRL-15773。 衍生物通过氧化5-O-甲硅烷基化C(26,27) - 环氧基和C(14,15; 26,27)二环氧-LL-F28249化合物的23-羟基获得,然后脱甲硅烷基化和衍生化 与氨基化合物。 这种新型化合物具有驱虫,外寄生性杀线虫,杀线虫,杀虫和杀螨活性,因此可用于治疗温血动物感染和农作物侵染。 还提供了含有本发明化合物作为其活性成分的组合物。
