  • Formulation of boronic acid compounds
    Patent number: 6958319
    Abstract: The present invention provides stable compounds prepared from boronic acid and lyophilized compounds thereof of the formula (1): in which Z1 and Z2 are moieties derived from sugar. The invention also provides methods for preparing such compounds. Lyophilizing a mixture comprising a boronic acid compound and a moiety derived from sugar produces a stable composition that readily releases the boronic acid compound upon reconstitution in aqueous media.
