Synthesis, labelling and evaluation of hydantoin-substituted indole carboxylic acids as potential ligands for positron emission tomography imaging of the glycine binding site of the N-methyl-d-aspartate receptor
hydroxy moiety to obtain the radiolabelled ligands through an alkylation reaction. Radiosynthesis was achieved by labelling the precursor ethyl 4,6-dichloro-3-((3-(4-hydroxyphenyl)-2,4-dioxoimidazolidin-1-yl)methyl)-indole-2-carboxylate with 2-[18F]fluoroethyl tosylate or [11C]methyliodide and subsequent cleavage of the ethyl ester moiety. This gave the final products in overall decay-corrected radiochemical

The present invention is directed toward novel fluorine-18 labeled rhodamine dye derivatives and methods of making the same. The present invention is also directed toward methods of using novel fluorine-18 labeled rhodamine dye derivatives as positron emission tomography imaging agents and myocardial perfusion imaging agents.
biological targets for the specific visualization of such pathologies, in particular by using radiolabeled MMP inhibitors (MMPIs). The aim of this work was to develop a radiofluorinatedmolecularprobe for noninvasive in vivo imaging for the detection of up‐regulated levels of activated MMPs in the living organism. Fluorinated MMPIs (26, 31 and 38) based on the pyrimidine‐2,4,6‐trione lead structure
