    摘要: The present invention is related to a pharmaceutical composition for a liver-receptor imaging injection, the pharmaceutical composition including a bi-functional compound which has a ASGPR specificity, wherein the bi-functional compound includes a backbone of alpha-amino acid (or the derivatives thereof) and a poly-galactosamine chain (or a poly-lactose chain) connected to the alpha-amino acid. Thereby, the pharmaceutical composition can quantify potential of liver storage ability and evaluate severity of the course of liver disease. A liver-receptor imaging injection using the same and the one-step dispensing method thereof are also provided to improve defects of iodine-labeled and overcome disadvantages of the reduced labeling-yield and the instability after autoclave sterilization.

    摘要: A radiolabeling method using a multivalent glycoligand as hepatic receptor imaging agent is provided. The multivalent glycoligand-DTPA derivatives (In-111-DTPA-hexa lactoside and In-111-DTPA-tri-galactosamine glycoside) labeled with In-111 are used as hepatic receptor imaging agent. The effects of imaging of a hepatic receptor in different species are evaluated, the lowest specific radioactivity values of hepatic receptor imaging required in different species are discovered. Since the specificity of the human ASGPR closely resembles that of the mouse. This kind of radiolabelling method, agent and related study about specific radioactivity could be used in clinical trial in the future.

    摘要: This invention provides novel liver targeting agents and their synthetic methods. A liver targeting agent, with a lysine based nitrilotriacetic acid structure as backbone which acquires multivalency with saccharide groups, to bind with a galactosamine chain or lactose chain is disclosed. In particular, only one amino acid L-lysine is involved to provide trivalency. All carboxyl groups in Nε-benzyloxycarbonyl-Nα-dicarboxymethyl-L-lysine can be conjugated with three glycosides of ahGalNAc or ahLac in one step. This invention also provides a hexa-lactoside. In particular, the TFA-AHA-Asp was used to conjugate 2 molecules of NTA(ahLac)3. This invention also provides a method for adding a spacer between NTA and DTPA. The extended hepatocyte-specific glyco-ligand has higher 111In-radiolabelling yield than those non-extended.

    摘要: A method for preparing a precursor used to label hepatocyte receptors is revealed. The precursor contains a bifunctional structure including trisaccharide and DTPA ligand. During synthesis processes of the precursor, silica gel columns and Reverse phase-18 (RP-18) columns are used for purification. Thus both the purification times and cost of each purification are reduced. Moreover, use diethyl ether to facilitate precipitation of products and remove a part of coupling reagent. Removing the coupling reagent helps purification of products. Furthermore, Nα,Nα-bis(carboxymethyl)-L-lysine hydrate and benzyl chloroformate are coupled to form a trisaccharide skeleton so as to ensure the yield rate of trisaccharide structure.

    摘要: The preparation method of radiation-sensitive copolymer carrier for coating radiated nanoparticles and/or chemotherapy drugs includes forming a nanosphere by diselenide block copolymers and DSPE-PEG-biomarkers to coat chemotherapy drugs and/or radiated nanoparticles that can be released from the opened nanosphere by protons penetrating tissue during proton therapy. The treatment effect of proton therapy is enhanced by two ways of using the radiated nanoparticles released from an opened nanosphere to produce nuclear fission with the protons for releasing electrons to destroy cancer cells of tumor and the chemotherapy drugs released from the opened nanosphere for distributing among tissue to kill the cancer cells of the tumor.
