  • Publication number: 20210355160
    Abstract: Disclosed is a process for the purification of lipopolypeptide antibiotics from culture broths which comprises: a) removal of the mycelium from the broth; b) anion-exchange chromatography of the solution resulting from stage a), eluting with di- or trivalent ions; c) optional concentration of the purified fraction resulting from stage b); d) hydrophobic interaction chromatography of the fraction resulting from stage b) or c), eluting with C1-C4 alcohols; e) cation-exchange chromatography of the desired lipopolypeptide-enriched fraction resulting from stage d), eluting at a pH equal to or greater than the isoelectric point of the lipopolypeptide; and f) dialysis, concentration and freeze-drying or spray-drying of the purified lipopolypeptide.

  • Patent number: 10632144
    Abstract: Disclosed is a low molecular weight (1000-5000 daltons) chondroitin sulfate (CS) produced by chemical sulfation of a non-sulfated chondroitin backbone (K4 capsular polysaccharide) obtained with biotechnology techniques. The CS described is substantially monosulfated, mainly at the 6-position, with very little sulfation at the 4-position, and with a mono/disulfated disaccharide ratio and charge density similar to those of natural CS. Said biotechnological chondroitin sulfate (CS) is useful in the treatment and prevention of osteoarthritis and in acute and chronic inflammatory processes.

  • Patent number: 9908947
    Abstract: The present invention discloses a process for the production of chondroitin sulphate with an average molecular weight (Mw) of 10-30 kDa by chemical sulphation starting from an unsulphated chondroitin backbone, obtained in turn by acid hydrolysis of capsular polysaccharide K4 made directly from E. coli strain O5:K4:H4, or directly produced from a genetically modified strain of E. coli. Sulphation of the N-acetyl-D-galactosamine residue at position 4 or 6 takes place simultaneously in the same polysaccharide chain, simulating the sulphation pattern observed in natural chondroitin sulphate, unlike the sulphation obtained with the synthesis methods described to date.

  • Publication number: 20160074429
    Abstract: Disclosed is a low-molecular-weight (1000-5000 daltons) chondroitin sulphate (CS) produced by chemical sulphation and subsequent depolymerisation of a non-sulphated chondroitin backbone obtained with biotechnology techniques. The CS described is substantially monosulphated, mainly at the 6-position, with very little sulphation at the 4-position, and with a mono/disulphated disaccharide ratio and charge density similar to those of natural CS. Said biotechnological chondroitin 6-sulphate (C6S) is useful in the treatment and prevention of osteoarthritis and in acute and chronic inflammatory processes.

  • Patent number: 8664196
    Abstract: The present invention provides a shark-like chondroitin sulphate and a process for the preparation thereof. In particular, the present invention relates to a shark-like chondroitin sulphate, having a very low amount of 4-sulphate, a high charge density and a biological activity comparable to natural chondroitin sulphates. The invention also relates to a process for the preparation of said shark-like chondroitin sulphate affording substantially higher productivities and better reproducibility of product quality. The shark-like chondroitin sulphate of the invention shows a high molecular mass and its in vitro biological and anti-inflammatory effectiveness has been shown to be comparable to that of natural products making this polysaccharide potentially useful as a drug in pharmaceutical preparations and nutraceuticals.
