Abstract
Avermectin compounds are glycosylated at the 4',13- Or 14a-positions by adding the avermectin compounds to the fermentation medium of a novel strain of Streptomyces avermitilis. The 13-hydroxy and 14a-hydroxy methyl groups of the avermectin compound are glycosylated with a glycosyl moiety, specifically an oleandrose group. The new strain offers the added advantage of not producing any C5-O-methylation products. The compounds are potent anthelmintic and antiparasite agents, and compositions for such uses are also disclosed.
