  • Patent number: 7838549
    Abstract: The present invention provides a novel linker compound which minimizes any nonspecific hydrophobic interactions and is capable of easily adjusting the length to a disulfide group subjected to metal bond to thereby enable effective formation of a metal-sulfur bond; novel ligand conjugate and ligand carrier, and a process for producing them. The linker compound is of a structure represented by the following general formula (1) where a, b, d, e are independently an integer of 0 to 6. X has a structure serving as a multi-branched structure moiety including three or more hydrocarbon derivative chains, wherein the hydrocarbon derivative chains each include an aromatic amino group at an end thereof, and may or may not include a carbon-nitrogen bond in a main chain thereof. The ligand conjugate includes the linker compound having a sugar molecule introduced therein.

  • Patent number: 7183067
    Abstract: A versatile linker compound has a structure represented by following general formula (1), wherein Y has a structure represented by O or NH, and X has a structure serving as a multi-branched moiety including four hydrocarbon derivative chains each of which has an aromatic amino group at an end thereof, and may or may not have a carbon-nitrogen bond in a backbone thereof. With the versatile linker compound, sugar molecules can be two-dimensionally arranged on a surface of a protein-analyzing supporter with high reproducibility. Also, a ligand includes the versatile linker compound and a sugar molecule introduced thereinto.

  • Patent number: 6200955
    Abstract: The present invention provides heparin antagonist peptides. The heparin-binding peptides of the present invention specifically neutralize heparin's conventional anticoagulant properties without causing deleterious hemodynamic side-effects or exacerbation of the proliferative vascular response to injury. More specifically, the heparin-binding compounds of the present invention are short-duration drugs to be used in elective or emergency situations which can safely and specifically neutralize heparin's conventional anticoagulant properties without causing deleterious hemodynamic side-effects or exacerbation of the proliferative vascular response to injury.
