  • Patent number: 6191266
    Abstract: A number of modified nucleosides are disclosed composed of modified sugar moieties which contain substituents at C1 and C4 positions, or branched substituents at C3 and C5 positions of deoxyribose or ribose. Each nucleoside is converted to or properly protected and then converted to the corresponding phosphoramidites. These phosphoramidites are used to assemble oligonucleotides in which there is at least one of the forenoted nucleosides. These sugar modified oligonucleotides have the potential to be used as antisense therapies since they are expected to enhance nuclease resistance and cellular uptake while they maintain sequence-specificity and affinity to nucleic acid targets in vitro or in vivo.

  • Patent number: 6191271
    Abstract: The present invention is directed to novel compositions and their use in the treatment of inflammatory responses. Specifically, the invention is directed to novel synthetic oligosaccharide constructs and their use to block lymphocyte binding to correspondent oligosaccharides on the endothelial surface, and thus reduce or otherwise ameliorate an undesired inflammatory response. The invention is further directed to the use of such constructs in other disease states characterized by selectin binding, such as bacterial infections and metastatic cancers.

  • Patent number: 6191272
    Abstract: The invention relates to a process for the preparation of endo-nortropine using 8-benzyl-nortropan-3-one perchlorate, as well as the latter product. Endo-nortropine is the key product for the production of important azonia-spironortropanol esters, which are used as pharmaceuticals, particularly spasmolytics. There are three different synthesis methods for the preparation of said intermediate, which lead to different disadvantages. These problems are obviated by the present invention through the two-stage treatment of 8-benzyl-nortropan-3-one perchlorate with catalytically activated hydrogen, the starting product initially being prehydrogenated in aqueous suspension and at atmospheric pressure and ambient pressure with a palladium catalyst, at the end of the reaction the catalyst is recovered by filtration, the filtrate is passed over an anion exchanger and the now alkaline reacting solution is rendered turbulent at 1000 to 1500 r.p.m.
