  • Oxidized carotenoid fractions and ketoaldehyde useful as cell-differentiation inducers, cytostatic agents, and anti-tumor agents
    Patent number: 7132458
    Abstract: This invention features fractionated oxidized carotenoid or retinoid mixtures, and individual components thereof, which are useful as cell-differentiation-inducing, anti-proliferative, anti-metastatic and anti-tumor agents. The mixtures and compounds of the invention can be used alone or in combination with other anticancer agents for the treatment of cancer.
    Type: Grant

  • Supported dendrimer catalyst
    Patent number: 6288253
    Abstract: Dendrimers were directly and covalently attached to solid supports via siloxy bonds. After complexation with transition metals, the dendrimers were used as catalysts. The supported dendrimers were stable and easily separated from the reaction mixture.

  • Pyrroline N-oxide derivatives
    Patent number: 5354871
    Abstract: Derivatives of 3,5-substituted pyrroline N-oxides having substituents in the 4-position have been prepared, with the 4-position substituents being selected from certain ester, polyether, and alkanoyl groups, the latter having components which bind to biological substrates. These specific derivatives are effective as spin traps for different types of free radicals to form persistent nitroxide adducts of extended half life. These adducts can be characterized by ESR spectrometry technique and provide information e.g. concerning the identification of free radicals.
