Abstract:
Objective To observe the preliminary application value of 18 F-MK-6240 automatically synthesized with AllinOne synthesis module in Alzheimer disease(AD).Methods Based on AllinOne synthesis module,18 F-labeled intermediate 18F-MK-6240-Boc was formed with 18F-MK-6240 precursor through nucleophilic reaction with 18 F-.After hydrolyzed by acid,separated by high performance liquid chromatography and purified by solid-phase extraction,18F-MK-6240 was obtained,and quality control was performed.18F-MK-6240 PET/CT scanning was performed in 1 AD patient and 1 non-AD patient with cognitive impairment who were prospectively enrolled,and the preliminary application value of the product was observed.Results 18 F-MK-6240 was successfully automatically synthesized based on AllinOne synthesis module,the synthesis time was 80 min,no-corrected synthesis efficiency was 20.74%±2.31%,radiochemical purity was greater than 95%,and sterility test,bacterial endotoxins test,abnormal toxicity test and solvent residual test all met national standards.18F-MK-6240 PET/CT showed tau protein deposition of bilateral frontal,parietal,temporal and insular lobes in AD patients,while no tau protein deposition was observed in non-AD patients with cognitive impairment.Conclusion 18F-MK-6240 could be automatically synthesized based on AllinOne synthesis module,with qualified product quality and clinical application value in AD.
