  • Publication number: 20130011421
    Abstract: The present invention relates to triterpene glycoside saponin-derived adjuvants, syntheses thereof, intermediates thereto, and uses thereof. QS-7 is a potent immuno-adjuvant that is significantly less toxic than QS-21, a related saponin that is currently the favored adjuvant in anticancer and antiviral vaccines. Tedious isolation and purification protocols have hindered the clinical development of QS-7. A novel semi-synthetic method is provided wherein a hydrolyzed prosapogenin mixture is used to synthesize QS-7, QS-21, and related analogs, greatly facilitating access to QS-7 and QS-21 analogs for preclinical and clinical evaluation.

  • Patent number: 8304525
    Abstract: Glycolipids of branched chain alkyl oligosaccharides according to this patent comprise of a primary alcohol branched in the 2-position and an oligosaccharide, covalently bond to the alcohol in either ?- or ?-linkage (shown in Formula I and Formula II). These compounds show particularly interesting phase behavior not found for the corresponding straight chain counterparts. The properties involve an ambient temperature liquid crystalline appearance and thermotropic liquid crystal phase polymorphism. Upon the latter, the formation of cubic phases is considered most interesting with respect to life science applications, e.g. liposome for drug delivery. Depending on the choice of sugar head group and alkyl tail, various levels of water miscibility may be adjusted to meet applications requirements (complete solubility for emulsifier applications, e.g. cosmetic creams, to limited water swelling only, e.g. for the preparation of artificial membranes).

  • Publication number: 20120232257
    Abstract: The invention relates to a nitration method having the following principles: a phosgene species is converted with two equivalent silver nitrates into a double-mixed anhydride of carbonic acid and nitric acid, known here as carbonic acid dinitrate (I). Said operation is carried out in situ, and the formed dinitrate decomposes spontaneously. In addition to carbon dioxide, nitrate ions and nitronium ions are formed, said ions comprising electrophiles which are necessary for nitration. The solution which is used is acetonitrile, and is insignificant if the alcohol species is dissolved or suspended. The necessary equivalent silver nitrates are introduced into the system and optionally heated or cooled to the desired temperature. Subsequently, the acid chloride is introduced slowly, drop by drop or slowly little by little. Phosgene, diphosgene, triphosgene and chloroformic acid ester can be used as carbonic acid dichloride and monochloride, and their thiocarbonic acid analogues.

  • Publication number: 20110028702
    Abstract: 13-benzenesulfonylhydrazone anthracyclines useful in producing improved yields in the synthesis 13-deoxyanthrcyclines, and an improved method of reducing 13-benzene-sulfonylhydrazone anthracyclines to 13-deoxyanthrcyclines wherein the reduction reaction is maintained at temperatures of about 55° C. to 64° C. without stirring or agitation. The reaction is completed with the addition of aqueous bicarbonate which forms the 13-deoxyanthracycline and precipitates. The precipitates are filtered and the precipitate and filtrate are extracted separately with organic solvents. The crude 13-deoxy anthracycline can be converted to 5-imino-13-deoxy anthracycline by reaction with methanolic ammonia. The reaction can also be performed with an acidic pyridinium salt instead of a strong acid so that neutralization of the reaction or extraction of the product is not necessary, thereby facilitating purification.

  • Patent number: 7875150
    Abstract: A new class of polymeric additives for papermaking is disclosed as well as a process for their manufacture, a method for their use and a paper sheet containing the addition. The additives can be used in paper manufacture as agents for improving retention, paper machine operation and the strength properties of the product. The additives are manufactured from a microbial biomass. The biomass that contains acetyl amino groups or other amides is chemically modified by hydrolysis of the amides to form primary amino groups. Under neutral or acidic conditions these primary amines become cationic, which assures a good absorption of the additive onto fibres and fines of pulp that is generally of anionic nature.

  • Patent number: 7875708
    Abstract: An amine or hydrazide derivative of a sialic acid unit, e.g. in a polysaccharide, is reacted with a bifunctional reagent at least one of the functionalities of which is an ester of N-hydroxy succinimide, to form an amide or hydrazide product. The product has a useful functionality, which allows it to be conjugated, for instance to proteins, drugs, drug delivery systems or the like. The process is of particular utility for derivatising amine groups introduced in sialic acid terminal groups of polysialic acids.

  • Patent number: 7862744
    Abstract: The present invention provides a method for preparing DMF for sucralose production, including, e.g., isolating DMF from a composition comprising DMF, water, and methanol, using a single-tower rectification system. In various embodiments of the present invention, the composition, after the removal of water and methanol, may be further dried/dehydrated, such as, by using a dehydration agent and/or filtration. The resulting substantially pure DMF may comprise at least about 98-99% DMF. The present invention further provides a method of preparing a composition comprising anhydrous sucrose for sucralose production, which may comprise mixing regular sucrose with a water-containing DMF composition, and drying the resulting sucrose-DMF composition. Also provided is a single-tower separation system for isolating DMF from a composition comprising DMF, water, and methanol.

  • Patent number: 7820627
    Abstract: The core structure of pentaerythritol has been used as a replacement for one or both sugars in lipid A, leading to the generation of a series of lipid A analogs. These lipid A analogs may further differ from lipid A with respect to, e.g., the number, nature and location of negatively charged groups, and the number, nature and location of the lipid chains. The lipid A analogs may be lipid A agonists useful as immunostimulatory agents, or lipid A antagonists useful in the treatment of septic shock. In a like manner, a residue of pentaerythritylamine may be used as a replacement for an amino sugar residue in a carbohydrate ligand having a biological activity of interest, generating a series of ligand analogs. These are useful, e.g., as haptens, inhibitors of bacterial-host cell adhesion, etc.
