    • The present invention generally provides compositions comprising a polysaccharide derivative, and methods of their preparation and use for the prevention or treatment of diseases caused by Neisseria meningitidis bacteria, particularly group B (NmB) strains, and by E. coli K1. The invention provides a de-N-acetylated PS derivative in which one or more residues of the PS has been modified by de-N-acetylation. The invention also includes derivatives in which one or more of the N-acetyl groups of PS containing de-N-acetylated PS are replaced with other N-acyl groups, usually a lower acyl group of C 2 - C 3 . Further, the invention includes de-N-acetylated PS derivatives containing long chain hydrocarbons, as well as conjugates in which the de-N-acetylated PS derivative is linked to a carrier, e.g., a carrier protein.
    • 本发明一般提供包含多糖衍生物的组合物,以及它们的制备方法和用于预防或治疗由脑膜炎奈瑟氏菌细菌,特别是B组(NmB)菌株和大肠杆菌K1引起的疾病的方法。 本发明提供了一种去N-乙酰化的PS衍生物,其中PS的一个或多个残基已经通过去N-乙酰化修饰。 本发明还包括其中包含脱-N-乙酰化PS的PS的一个或多个N-乙酰基被其他N-酰基,通常为C 2- ç 3 。 此外,本发明包括含有长链烃的去N-乙酰化PS衍生物,以及其中去N-乙酰化PS衍生物与载体(例如载体蛋白)连接的缀合物。
