摘要：

[F-18]-FBAU and [F-18]-FCAU have been synthesized and evaluated in vivo as markers for HSV1-tk gene expression. At 2 hours, uptake of [F-18]-FBAU and [F-18]-FCAU in HSV1-tk-positive tumors was 7.9-fold and 6.0-fold higher than the control tumors, respectively. Micro-PET images also showed very high uptake in HSV-tk tumors. Compared to [C-14]-FMAU, total uptake of [F-18]-FBAU and [F-18]-FCAU was similar in tk-positive cells, but the uptake ratio (tk+/wild) was higher. [F-18]-FCAU and [F-18]-FCAU appear to be potential PET imaging agents for gene expression. (C) 2004 Elsevier Inc. All rights reserved.
