  • Saccharopeptides and derivatives thereof
    Patent number: 5849709
    Abstract: Saccharopeptides and methods of using the novel saccharopeptides are described having the following structural formula I:W--?--Y--W--!.sub.m (I)wherein W is independently one or more saccharide(s); Y is independently --CO--NH-- or --NH--CO--; and m is an integer greater than or equal to one; or structural formula II:W--Y--?W--X--W--Y!.sub.n --W (II)wherein W is independently one or more saccharide(s); S is a difunctional or polyfunctional alkyl, aryl or aralkyl group, lipid, amino acid or peptide capable of covalently joining together said saccharides; Y is independently --CO--NH-- or --NH--CO--; and n is an integer greater than or equal to zero; or formula III:W--Y.sup.1 --X.sup.1 --Y.sup.2 --W (III)wherein W is independently one or more saccharide(s); X.sup.1 is a difunctional or polyfunctional alkyl, aryl or aralkyl group capable of covalently joining together said saccharides; Y.sup.1 is --NH--CO--; and Y.sup.2 is --CO--NH--.

  • Sulfated polysaccharides as inhibitors of smooth muscle cell proliferation
    Patent number: 5380716
    Abstract: Highly sulfated oligosaccharides in the form of hexasaccharide and octasaccharide compounds which have antiproliferative activity with respect to smooth muscle cells are useful in treatment of conditions characterized by unwanted smooth muscle cell proliferation such as a result of trauma or disease states such as asthma, congestive heart failure and hypertension. The oligosaccharides have increased ability to inhibit the proliferation of smooth muscle cells and decreased ability to act as an anticoagulant as compared with commercial heparin and/or unseparated fragments of heparin.

  • Process for the manufacture of heptakis-[2,6-di-O-methyl]-beta-cyclodextrin
    Patent number: 4542211
    Abstract: The invention relates to a process for the manufacture of heptakis-[2,6-di-O-methyl]-beta-cyclodextrin by methylating beta-cyclodextrin in an organic phase wherein beta-cyclodextrin is methylated with dimethylsulfate in the presence of an alkalihydroxide at temperatures of from -10.degree. to 0.degree. C.
