Outline of Final Research Achievements |
Fibroblast Growth Factor Receptor 1 (FGFR1), known as a kind of tyrosine kinase receptor, is suggested that it promotes exacerbation of certain tumors. This research contains a drug design, synthesis, and evaluation of a new PET probe targeting FGFR1. In vitro kinase assay, nonradioactive 9 showed inhibitory activity to FGFR1 (IC50 = 172.6 nmol/L). In vivo biodistribution study, [18F]9 showed high accumulation and high retention to FGFR1 amplification tumor (3.23% dose/g). On the other hand, high blood retention of RI was observed (2.92% dose/g), which will be a cause of high background. In conclusion, though some improvements for high hydrophilicity or low protein binding rate are necessary, [18F]9 is the first compound as FGFR1-targeting nuclear medicinal imaging probe, and [18F]9 provide beneficial information to FGFR1 imaging in the future.

Academic Significance and Societal Importance of the Research Achievements |
これまでに、FGFRを標的としたPET/SPECT分子イメージングプローブの開発は報告が無く、本プローブ開発は独創的な研究であると考えられる。開発したプローブを用いがん化のメカニズム、薬剤耐性へのメカニズムを解明し、遺伝子情報を含んだ新規核医学診断法の開発、さらに分子標的薬の開発への効率的なワークフローの構築へと繋げることが出来ると考えている。また、FGFRを標的とした分子標的薬の開発が世界的に進められており、本研究で得られた成果を創薬に応用することも可能である。
