30,394-00 23-OXO (KETO) AND 23-IMINO DERIVATIVES OF LL-F28249 COMPOUNDS ABSTRACT OF THE INVENTION The present invention relates to novel 23-oxo (keto) and 23-imino derivatives of LL-F28249.alpha., .beta., ?, .delta., .epsilon., 5, .theta., ? and .lambda. compounds. These LL-F28249 compounds (collectively) are isolates from the fermentation broth of Streptomyces cyaneogriseus subspecies noncyanogenus having deposit accession number NRRL 15773. The present 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 com- pounds. These novel compounds have potent anthelmintic, insecticidal, ectoparasiticidal, nematicidal and acari- cidal activity. Compositions containing these 23-oxo and 23-imino derivatives of LL-F28249 also are described herein.
