ABSTRACT:
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.
