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.

Cd-112 isotope is recycled from a Cd-112 chemical separated solution or a remainder of an electroplating solution having a Cd-112 target. The present invention recycles Cd-112 isotope with a low cost, a high purity and a high recycle rate. The recycled Cd-112 isotope can be easily stored. And, the Cd-112 isotope can be used as an imaging agent in nuclear medicine.

An automatic synthesis device for fluorine-18-ACETATE ([18F]fluoroacetate) consists of a machinery housing that has multiple reactors and multiple raw material containers, and uses multiple control valves between each reactor and container, and operates the control valves through a control system to charge the raw material from each container to each reactor in an automatic and sequential fashion to execute the six procedures: fluorination, azeotropic dewatering, synthesis (reaction with precursors), purification and separation, hydrolysis and neutralization, purification and collection. The operation simply requires adding raw materials to the containers in advance, turning on power, charging reactive gases. In 50 minutes, the process to produce the product will be completed. The operation is really simple and can effectively improve production efficiency.

An automated dispenser for radiopharmaceuticals is mainly for a platform to have a moving mechanism being able to move three-dimensionally back and forth, a syringe holder and a bottle holder. The syringe holder is for holding a plural number of syringes. The bottle holder has a reverse drug bottle. The moving mechanism has a syringe clamp rotatable around a horizontal axis and a syringe driving mechanism. The syringe clamp is activated to hold a syringe and move it to where the syringe needle is inserted to the drug bottle. The syringe driving mechanism and the syringe clamp are simultaneously associated with the syringe for drug-withdrawing action.

A method to produce a high-purity Zr-89 on a solid target through physical irradiation and measurement by selecting a target Barn value of the cross-sectional area of nuclear reaction, drawing a horizontal line to intersect at two points on the function diagram curve and drawing a vertical line downward from each of the two points intersecting at X-axis to obtain incident energy values at the two intersecting points on the X-axis, and followed by plotting an attenuation function diagram curve of penetration depth versus incident energy of Y-89(p,n)Zr-89, selecting an attenuation function diagram curve and a minimum attenuation position of the selected attenuation function diagram curve in correspondence to the incident energy in the interval of incident energy absorption range to obtain an optimal plating thickness value on the solid target.

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 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.

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.
