Abstract
The present invention relates to novel derivatives of LL-F28249 compounds. These LL-F28249 compounds preferably are derived via a controlled microbiological fermentation of Streptomyces cyaneogriseus subsp. non-cyanogenus having deposit accession numer NRRL 15773. The derivatives of the present invention have the 23-hydroxy group react to form a double bond in the 22,23 position. The novel derivatives of the present invention possess activity as anthelmintic, ectoparasitic, insecticidal, acaricidal and nematicidal agents.
