  • Patent number: 10494449
    Abstract: Polydisperse and charged polysaccharides are fractionated into low polydispersity fractions (preferably having pd<1.1), each containing species within a narrow range of molecular weights. An aqueous solution of the polydisperse polysaccharides is contacted with an ion exchange resin in a column and the polysaccharides are subjected to selective elution by aqueous elution buffer. The selective elution consists of at least 3 sequential elution buffers having different and constant ionic strength and/or pH and in which the subsequent buffers have ionic strength and/or pH than those of the preceding step. The new preparations are particularly suitable for the production of PSA-derivatised therapeutic agents intended for use in humans and animals.

  • Patent number: 10406209
    Abstract: Derivatives are synthesized of starting materials, usually polysaccharides, having sialic acid at the reducing terminal end, in which the reducing terminal unit is transformed into an aldehyde group. Where the polysaccharide has a sialic acid unit at the non-reducing end it may be passivated, for instance by converting into hydroxyl-substituted moiety. The derivatives may be reacted with substrates, for instance containing amine or hydrazine groups, to form non-cross-linked polysialylated compounds. The substrates may, for instance, be therapeutically useful drugs peptides or proteins or drug delivery systems.

  • Patent number: 10301396
    Abstract: The present invention relates to process for reducing the endotoxin content of a sample of fermentation broth containing polysialic acid and endotoxin comprising the sequential steps: (i) adding to the sample a base having a pKa of at least 12 to form a basic solution having a pH of at least 12, incubating the solution for a pre-determined time at a pre-determined temperature; and (ii) recovery of PSA, suitably by (iii) passing the sample through an anion-exchange column whereby polysialic acid is absorbed on the ion exchange resin; (iv) washing the column with one washing buffer, whereby polysialic acid remains absorbed on the ion exchange resin; and (v) eluting the polysialic acid from the column using an elution buffer to provide a product solution of polysialic acid having reduced endotoxin content.

  • Patent number: 9789163
    Abstract: The present invention relates to methods for producing N-terminal derivatives of proteins in which a polysaccharide, preferably having at least terminal sialic units, and preferably consisting essentially only of sialic acid units, is reacted at the N-terminus of a protein or peptide under controlled conditions to produce an N-terminal derivative. The controlled conditions include use of acidic pH for the derivatization step and a higher pH for purification. The derivatives are useful for improving pharmacokinetics and pharmacodynamics of proteins and peptides.
