MACROCYCLIC LACTONES, THEIR PRODUCTION AND PARASITICIDAL USES, COMPOSITIONS CONTAINING THEM, AND A BIOLOGICAL CULTURE SUITABLE FOR PRODUCING THEM

Novel parasiticidal compounds have the formula where the variables R1 and R2 have the following meanings for the compounds identified as A1, A2 and B1: They are made into compositions for the treatment of agricultural pests and parasitic infections, especially tapeworms. The compounds are made by fe...

Zusammenfassung:	Novel parasiticidal compounds have the formula where the variables R1 and R2 have the following meanings for the compounds identified as A1, A2 and B1: They are made into compositions for the treatment of agricultural pests and parasitic infections, especially tapeworms. The compounds are made by fermenting a culture of the novel microorganism Streptomyces sp. MA-5038 having the identifying characteristics of ATCC 31587 in an aqueous nutrient medium containing assimilable sources of carbon, nitrogen and inorganic salts.
