摘要
The preparation of 10-(2-[F-18]fluoroethoxy)-20(S)-camptothecin, a potential positron emission tomography tracer for the imaging of topoisomerase I in cancers, is described. 10-(2-[F-18]Fluoroethoxy)-20(S)-camptothecin was synthesized by the [F-18]fluoroalkylation of the corresponding hydroxy precursor molecule with 2-[F-18]fluoroethyl bromide ([F-18]FEtBr) in dimethylsulfoxide (DMSO) at 55 degrees C for 20 min; this was followed by purification using high performance liquid chromatography (HPLC) with a total preparation time of 60 min. The overall radiochemical yield was approximately 5.4-12 % (uncorrected), and the radiochemical purity was above 96 %.
