  Synthesis, biological evaluation, and molecular dynamics (MD) simulation studies of three novel F-18 labeled and focal adhesion kinase (FAK) targeted 5-bromo pyrimidines as radiotracers for tumor

  摘要：

  Focal adhesion lcinase (FAK) is considered as an attractive target for oncology. A series of F-18 labeled 5bromo-N-2-(4-(2-fluoro-pegylated (FPEG))-3,5-dimethoxyphenyl)-N-4-(4-methoxyphenyl)pyrimidine2,4-diamine derivatives were prepared and evaluated as the FAK targeted radiotracers for the early diagnoses of tumor. For the study of the FAK targeted drug molecules, this was the first attempt to develop the tumor diagnostic imaging agents on the radiopharmaceutical level. They inhibited the activity of FAK with IC50 in the range of 91.4-425.7 nM, and among which the result of the [F-19]2 was relatively good and had a modest IC50 of 91.4 nM. The [F-19]2 was also profiled in vitro against some other kinds of cancer related kinases (including two kinds of non-receptor tyrosine kinase: PYK2 and JAK2, and three kinds of receptor tyrosine kinase: IGF-1R, EGFR and PDGFR(3). It displayed 25.2 folds selectivity against PYK2, 35.1 folds selectivity against EGFR, and more than 100 folds selectivity against IGF-1R, JAK2 and PDGFRO. For the biodistribution in 5180 bearing mice, the corresponding [F-18]2 were also relatively good, with modest tumor uptake of 5.47 +/- 0.19 and 5.80 +/- 0.06 %ID/g at 15 and 30 min post-injection, respectively. Furthermore, its tumor/muscle, tumor/bone and tumor/blood ratio at 15 min post-injection were 3.16, 2.53 and 4.52, respectively. And its tumor/muscle, tumor/bone and tumor/blood ratio at 30 min post injection were 3.14, 2.76 and 4.43, respectively. In addition, coronal micro-PET/CT images of a mouse bearing 5180 tumor clearly confirmed that [F-18]2 could be accumulated in tumor, especially at 30 min post-injection. Besides, for the jI8F12, both the biodistribution data and the micro-PET/CT imaging study showed significantly reduced uptake of the radiotracer in the tumor tissue at 30 min post-injection in mice that received PF-562,271 (one of the reported best selective FAK inhibitor which was developed by Pfitzer Inc. and inhibited the activity of FAK with IC50 value of 1.5 nM) at 1 h before the injection of radiotracer. In combination with the above kinase profiling assay, it could be indicated that the uptake of [F-18]2 in tumor of the mouse model was due to FAK expression, and that [F-18]2 might be a kind of selectively FAK targeted tumor imaging agents. What's more, the results of the MD (molecular dynamics) simulations were in agreement with the changing trends of the interaction between the different F-19 standards and the FAK (expressed as the in vitro inhibitory abilities of enzymatic activities of FAK in this article), which was also in agreement with and had great effect on the changing trends of the uptake of the corresponding F-18 labeled tracers in tumor and some of theirs target/non-target ratios.

  摘要：

  基于计算机辅助药物设计，成功合成了一系列新型嘧啶衍生物，并通过1 H NMR，13 C HNMR和MS光谱进行了表征。评估了所有新化合物对粘着斑激酶的活性，并显示出与对照药物相比较低的IC 50值。特别地，对于化合物8i，其IC 50值为0.060μM，表明其作为粘着斑激酶抑制剂的优点。为了评估这些化合物作为PET显像剂在癌症检测中的潜力，将化合物8a，8c，8h和8i依次标记为18F.四种18 F标记的嘧啶衍生物在生理盐水和小鼠血浆中显示适当的log  P值和高稳定性。值得注意的是，化合物[ 18 F] - 8A与在苯环的4-甲氧基表现出良好的体内小鼠轴承S180肿瘤，促进化合物[的另一微PET成像研究生物分布数据18 - F] 8A。在注射后60分钟时将S 18肿瘤小鼠的[ 18 F- 8a ]的microPET图像显示出S180肿瘤的摄取很明显。这些结果表明化合物[ 18 F] -8a

  Finally, in order to further increase the uptake of the F-18 labeled tracer in tumor, the following points should arouse attention, which could also be considered as the new findings and contributions of this study to the field of the tumor imaging agents: (1) the F-18 labeled tumor radiotracers which have closer interaction with the FAK, should be further designed, via building of models such as 3D-QSAR
