Abstract

The purpose of this study is to synthesize the radio fluorine labelled isoquinoline salt derivative as new radiopharmaceutical for imaging tumors using positron emission tomography (PET). The planarity of isoquinoline allows to inhibit topoisomerase or intercalate between adjacent DNA base pairs, which result in producing double strand breaks in the DNA and a cell death. Therefore, the isoquinoline has seemed to have a potential anticancer activity. In order to obtain 2-(5-[$^{18}F$]fluoropentylisoquinolinium salt with good radiochemical yield, tosylated precursors have been synthesized. The labelling reaction was carried out for 30 minute in HMPA at $120^{\circ}C$. The radiochemical yield was about 50~60%.
