内容記述 | The aimofthisstudywastodevelopanefficientfullyautomatedsynthesismethodtoachieveahigh radiochemicalyieldof[18F]FAZA withasmallamountofprecursor.Asmallcartridgecontaining25mgof theQMAresinwaspreparedandevaluatedtoobtain[18F]F1 in asmallquantityofbase(K2CO3), which might allowtheuseofasmallamountofprecursor. Thelabelingandhydrolyzingconditionsfor[18F]FAZA synthesiswerealsoinvestigatedmanually.No-carrier-added[18F]F1 was trappedonthesmallQMA cartridgeandelutedwithamixtureofKrytofix222(2.26mg,6.0 mmol)andK2CO3 (0.69 mg,5.0 mmol)in 70%MeCN(0.4mL).Theautomatedsynthesisof[18F]FAZA wasoptimallyperformedwithamodifiedNIRS originalsynthesissystemforclinicaluse,bylabeling2.5mg(5.2 mmol)oftheprecursorinDMSO(0.4mL)at 120 1C for10min,andthenbyhydrolyzingthe 18F-labeledintermediatewith0.1MNaOH(0.5mL)atroom temperaturefor3min.Usingtheabovecondition,the[18F]FAZAinjectionwasobtainedwithahigh radiochemicalyieldof52.475.3%(decay-corrected, n¼8) within50.571.5min. |
