D-[$^18}F$]FMAU and L-[$^18}F$]FMAU are F-18 labeled nucleoside analogue which have been efficiently synthesized in order to be a PET imaging probe. D-[$^18}F$]FMAU and L-[$^18}F$]FMAU were compared as PET imaging agents using HSV1-TK gene expressing tumor-bearing mice. Their cellular uptake profiles were also compared using MCA and MCA-TK cell lines. D-[$^18}F$]FMAU demonstrated higher cellular uptake and higher accumulation in MCA-TK tumor regions than L-[$^18}F$]FMAU. On the other hand, L-[$^18}F$]FMAU showed higher MCA-TK/MCA ratio of %ID/g than that of D-[$^18}F$]FMAU. L-[$^18}F$]FMAU can be utilized as a good candidate for HSV1-TK PET imaging. It can be used for antiviral drug evaluation.
D-[$^18}F$]FMAU和L-[$^18}F$]FMAU是F-18标记的核苷类似物,它们被有效地合成为PET成像探针。D-[$^18}F$]FMAU和L-[$^18}F$]FMAU被用作PET成像剂,用于携带HSV1-TK基因的肿瘤小鼠。它们的细胞摄取曲线也通过MCA和MCA-TK细胞系进行了比较。D-[$^18}F$]FMAU在MCA-TK肿瘤区域表现出比L-[$^18}F$]FMAU更高的细胞摄取和更高的积累。另一方面,L-[$^18}F$]FMAU的MCA-TK/MCA比值(%ID/g)比D-[$^18}F$]FMAU更高。L-[$^18}F$]FMAU可以作为HSV1-TK PET成像的候选药物。它可用于抗病毒药物评估。
