  • Patent number: 7470783
    Abstract: Novel compounds are provided which are useful as linking groups in chemical synthesis, preferably in the solid phase synthesis of oligonucleotides and polypeptides. These compounds are generally photolabile and comprise protecting groups which can be removed by photolysis to unmask a reactive group. The protecting group has the general formula Ar—C(R1)(R2)—O—C(O)-wherein: Ar is an optionally substituted fused polycyclic aryl or heteroaromatic group or a vinylogous derivative thereof; R1 and R2 are independently H, optionally substituted alkyl, alkenyl or alkynyl, optionally substituted aryl or optionally substituted heteroaromatic, or a vinylogous derivative of the foregoing; and X is a leaving group, a chemical fragment linked to Ar—C(R1)(R2)—O—C(O)— via a heteroatom, or a solid support; provided that when Ar is 1-pyrenyl and R1 and R2 are H, X is not linked to Ar—C(R1)(R2)—O—C(O)— via a nitrogen atom.

  • Patent number: 7205284
    Abstract: Immunostimulatory polysaccharides can be preferentially extracted from food-grade microalgae using an aqueous ethanol extraction procedure. The resulting preparations exhibit extremely potent immunostimulatory activity. The preferential extraction of these immunostimulatory polysaccharides is dependent on the concentration of ethanol used and the extraction temperature. The most efficient conditions are 50% ethanol concentration at temperatures between 60° and 70° C. The isolated polysaccharide preparations are potentially useful as a botanical or pharmaceutical preparation to improve immune function.
