The present invention relates to novel 23-imino derivatives of LL-F28249.alpha., .beta., .gamma., .delta., .epsilon., .zeta., .theta., .iota., and .lambda. compounds. These LL-F28249 compounds (collectively) are isolates from the fermentation broth of Streptomyces cyaneogrisesu subspecies noncyanogenus having deposit accession number NRRL 15773. The precursor 23-oxo compounds are prepared by selectively oxidizing suitably protected 23-hydroxy compounds of LL-F28249 components using oxidizing agents. Subsequently, the 23-oxo compounds are converted to the 23-imino compounds. These novel compounds have potent anthelmintic, insecticidal, ectoparasiticidal, nematicidal and acaricidal activity. Compositions containing these 23-oxo and 23-imino derivatives of LL-F28249 also are described herein.
本发明涉及LL-F28249α,β,γ,δ,ε,ζ,θ,ι和λ化合物的新型23-亚胺衍生物。这些LL-F28249化合物(总称)是从青灰链霉菌亚种非氰原菌的发酵液中分离得到的,具有存储访问编号NRRL 15773。通过使用氧化剂选择性氧化适当保护的LL-F28249组分的23-羟基化合物,制备前体23-酮化合物。随后,将23-酮化合物转化为23-亚胺化合物。这些新型化合物具有强效的驱虫、杀虫、杀外寄生虫、杀线虫和杀螨活性。本文还描述了含有这些LL-F28249的23-酮和23-亚胺衍生物的组合物。
