Abstract

The embodiment of the invention relates to a synthesis method of <18>F-labeled amino acid polypeptide drugs and a kit. The method comprises the following steps: capturing <18>F<-> ions produced by a cyclotron through an anion small column; introducing 0.4-0.5ml of normal saline into the anion small column, then eluting the <18>F<-> ions to obtain first reaction liquid, and introducing the first reaction liquid into a reaction bottle; adding precursor-AlCl3 acid solution-organic solvent mixed liquid with a pH value of 4-5 into the reaction bottle, wherein the precursor is NOTA derivative, and NOTA is triazacyclononane triacetoxyl or triazacyclononane diacetoxyl; heating the reaction bottle to 100-110 DEG C and carrying out labeled synthesis; cooling, then adding water into liquid in a solid-phase extraction reaction bottle and diluting; separating the diluted liquid in the solid-phase extraction reaction bottle through a solid-phase extraction small column and enabling products to be obtained to be adsorbed to the solid-phase extraction small column; washing the solid-phase extraction small column with water and removing organic solvents and impurities; washing the solid-phase extraction small column with alcohol, putting the products to be obtained in a product bottle, and adding preparation liquid to obtain the synthesized products.

Description

technical field [0001] The present invention relates to the field of drug synthesis, in particular to a 18 F-labeled amino acid polypeptide drug synthesis method and kit. Background technique [0002] 18 F-fluorodeoxyglucose ( 18 F-FDG) has been widely used in early tumor diagnosis and guiding treatment, but it is a non-specific positron emission tomography (PET drug), prone to false positive and false negative results. 18 F-labeled amino acids and targeting receptor specificity 18 F-labeled polypeptide PET drugs can make up 18 The serious shortage of F-FDG is an important development direction for the development of PET drugs. However, existing general 18 The method for labeling biomolecules involves the use of N-succinimide-4- 18 F-fluorobenzoate ( 18 F-SFB) and 18 F-4-nitrophenyl-2-fluoropropionate ( 18 F-NFP) marks the amino acid polypeptide-NH2 group, and the reaction steps are many, the operation is more complicated, the synthesis time is long, and it is diff...
