  • Patent number: 5932774
    Abstract: A method for the preparation of D-chiro-inositol from kasugamycin, comprising the steps of: (a) reacting kasugamycin with an acetylating agent to form a crude hexa-acetate intermediate; (b) purifying the crude intermediate to form purified hexa-acetate intermediate; (c) deacetylating the purified intermediate to form D-chiro-inositol; and (d) isolating the D-chiro-inositol. The method permits efficient, large-scale preparation of D-chiro-inositol without the need for extensive chromatographic purification of the final D-chiro-inositol product.

  • Patent number: 5488052
    Abstract: The present invention relates to a novel aqueous flowable composition of fenazaquin. It was found that conventional aqueous flowable formulations resulted in a product that lost miticidal activity during storage. The low miticidal activity was found to be due to an unacceptable level of particle size growth during storage. It has been found that an aqueous flowable fenazaquin formulation of satisfactory particle size stability can be made when a higher than normal concentration of sodium naphthalene formaldehyde condensate dispersant is utilized in the formulation.

  • Patent number: 4956293
    Abstract: A novel antibiotic, A 42867, is prepared by cultivating the strain Nocardia sp. ATCC 53492, or an antibiotic A 42867-producing mutant or variant thereof, under submerged aerobic conditions in the presence of assimilable sources of carbon, nitrogen and inorganic salts. The antibiotic and its addition salts are useful in the treatment of infectious diseases and as growth promotant agents.
