  • Biotin-Amino Acid Conjugate Useful as a Hydrogelator and Hydrogel Prepared Therefrom
    Publication number: 20090011025
    Abstract: A biotin-amino acid conjugate, wherein the carboxylic group of biotin and the ?-amino group of an amino acid is linked by an amide bond, is biocompatible and has an excellent gelation capability in an aqueous medium. Accordingly, a hydrogel prepared therefrom is useful as a drug delivery system.

  • Calix[4]arene-nucleoside and calix[4]oligonucleotide hybrids
    Patent number: 7166718
    Abstract: The present invention relates to calix[4]arene-nucleoside hybrids containing calix[4]arene moieties and calix[4]arene-oligonucleotide hybrids as a DNA hairpin structure mimics synthesized by using the calix[4]arene-nucleoside as a key building block. Calix[4]arene-nucleoside and calix[4]arene-oligonucleotide hybrids of the present invention can effectively recognize DNA or RNA through triplex formation by bonding between calix[4]arene containing cavity and biologically active substance.
