  • Publication number: 20210401863
    Abstract: A method for treating or preventing a Neisseria gonorrhoeae infection in a subject is provided. The method comprises administering to the subject an effective amount of a compound of general formula I below or a pharmaceutical composition comprising the compound. The compound is a cytidine 5?-monophospho-nonulosonate (CMP-NulO) analog compound, such as cytidine 5?-monophospho-3,7-dideoxy-7-azido-D-glycero-D-galacto-nonulosonic acid (CMP-KDN7N3).

  • Patent number: 9157105
    Abstract: The sialic acid-like sugar legionaminic acid is found as a virulence-associated surface glyco-conjugate in Legionella pneumophila and Campylobacter coli. In this work, we have purified and biochemically characterized eleven candidate biosynthetic enzymes from C. jejuni, thereby fully reconstituting the biosynthesis of legionaminic acid and its CMP-activated form, starting from fructose-6-P. This pathway involves unique GDP-linked intermediates and provides a facile means for the efficient large-scale synthesis of an important sialic acid mimic and novel precursors.
