摘要： A precursor SnBZM for a dopamine receptor radiotracer and a method for preparing the same are revealed. The precursor includes a tributyltin group (Bu3Sn) that is easy to be replaced. Thus a dopamine receptor radiotracer 123I-IBZM can be produced at high yield rate by a substitution reaction of the precursor. At the same time, both the method for preparing the precursor SnBZM and a method for preparing a reference standard IBZM are simplified. Moreover, stability of each product is improved.

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： A radioactive mixture and a manufacturing method thereof are disclosed. The radioactive mixture (188Re-MN/Lipiodol mixture) is formed by chelating reaction of MN series compounds that are amine-amide-disulfide amine quadric-dentate chelate ligands with TcO4−/or ReO4−, and then dissolved in Lipiodol. Moreover, the 99mTc/or 188Re of the TcO4−/or ReO4− avoids bone marrow injuries caused by free 90Y. By the feature of the Lipiodol that stays in liver tumors for a long period, the radioactive mixture is applied to treat liver cancers by injection so that injuries caused by surgical operations can be prevented. 188Re-MN/Lipiodol is used for liver cancer, breast cancer or other solid tumors treatment. Re-188 MN or Re-188 MN/Lipiodol can be mixed with anticancer drugs, hydrogel, liposome, micelle or other nano-particles to form the multifunctional therapeutic modality.
