Patent number: 4886829Abstract: 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.Type: GrantFiled: March 6, 1987Date of Patent: December 12, 1989Assignee: American Cyanamid CompanyInventors: Goro Asato, Susan Y.

Patent number: 4886830Abstract: The present invention relates to novel derivatives of LL-F28249 compounds wherein the 23-hydroxyl group is replaced with hydrogen and the double bond at the C(26,27)-position is epoxidized concomitant with or without epoxidation of the double bond at the C(14,15)-position. The LL-F28249 compounds (collectively) are isolates from the fermentation broth of Streptomyces cyaneogriseus subspecies noncyanogenus having deposit accession number NRRL 15773. The compounds of the present invention are derived by regioselective epoxidation of 5,23-O,O-bissilylated LL-F28249 compounds at low temperature, desilylation, re-silylation of the 5-hydroxyl group, thiocarbonylation of the 23-hydroxyl group, disilyation followed by tributyltin hydride reduction.

Patent number: 4857544Abstract: The present invention relates to novel derivatives of LL-F28249 compounds wherein the pendent C(26,27) olefinic group at C(25) is converted into a 27-bromo or 27-chloro-26-methylene group. The 27-bromo compounds are derived by reacting the LL-F28249 compounds or 5-0-trisubstituted silyl LL-F28249 compounds with N-bromoacetamide or N-bromosuccinimide in aqueous acetone, followed by desilylation for silylated LL-F28249 intermediates.
