Wang, Ji-Quan published the artcileNovel radiosynthesis of PET HSV-tk gene reporter probes [18F]FHPG and [18F]FHBG employing dual Sep-Pak SPE techniques, Recommanded Product: 5-(2-Bromoethyl)-2,2-dimethyl-1,3-dioxane, the publication is Bioorganic & Medicinal Chemistry Letters (2003), 13(22), 3933-3938, database is CAplus and MEDLINE.
Positron emission tomog. (PET) herpes simplex virus thymidine kinase (HSV-tk) gene reporter probes 9-[(3-[18F]fluoro-1-hydroxy-2-propoxy)methyl]guanine ([18F]FHPG) [(I); X = O] and 9-(4-[18F]fluoro-3-hydroxymethylbutyl)guanine ([18F]FHBG) [I; X = CH2] were prepared by nucleophilic substitution of the appropriate tosylated precursors with [18F]KF/Kryptofix 2.2.2 followed by a quick deprotection reaction and purification with a simplified dual Silica Sep-Pak solid-phase extraction (SPE) method in 15-30% radiochem. yield.
