Novel group B streptogramine-like compounds of general formula (I), and a method for preparing streptogramines by muta-synthesis using a mutated micro-organism to influence the biosynthesis of at least one of the precursors of group B streptogramines, are disclosed. Novel nucleotide sequences involved in the biosynthesis of said precursors, and their uses, are also disclosed.
The present invention provides cyclic depsipeptide compounds of formula (I) and compositions comprising the compounds that are effective against parasites that harm animals. The compounds and compositions may be used for combating parasites in or on mammals and birds. The invention also provides for an improved method for eradicating, controlling and preventing parasite infestation in birds and mammals.
