Taking advantage of click chemistry, a library of N-arylpiperazinylmethyl triazoles bearing fluoro substituted appendages was synthesized and the target compounds were investigated for dopamine and serotonin receptor binding. With the aim to bias their hydrophilicity and to optimize their D4 receptor affinity and selectivity, a concise series of triazoles containing fluoroalkyl, fluoroalkoxy, fluoroalkoxyphenyl, and deoxyfluoroglucosyl substituents was studied. The D4 receptor affinity and selectivity could be tuned by altering the chemical moiety attached to the triazole unit. Among the test compounds, the fluoroethoxyphenyl derivative 15b showed weak partial agonism at D4 and a K i value of 14 nM, while its fluoropropoxyphenyl homologue 16a turned out to act as a neutral D4 antagonist (Ki = 5.1 nM). Both, 15b and 16a revealed an excellent balance between D4 receptor affinity and subtype selectivity, providing lead candidates for the development of 18F-labeled radioligands for D4 receptor imaging studies by positron emission tomography (PET).

CXCR4 is involved in various diseases such as inflammation, tumor growth, and cancer metastasis through the interaction with its natural endogenous ligand, chemokine CXCL12. In an effort to develop imaging probes for CXCR4, we developed a novel small mole

A robust and simple protocol for the synthesis of arylfluorophosphonates

Fluorophosphonates represent powerful probes for the identification and analysis of active serine hydrolases in activity based protein profiling. Although alkylphosphonofluoridates are widely used for such purposes, little is known about the synthesis and purification of arylphosphonofluoridates, which may be useful tools for screening enzyme activities toward aromatic esters. Our optimized route makes this subclass of transition state inhibitors broadly accessible for a diverse series of phosphonic acid derivatives using a combination of selective monoesterification with EDC·HCl and subsequent mild fluorination with DAST. All compounds were isolated as pure materials using a simple acid-base extraction protocol in 76-93% yields over two steps. These probes can be stored under an inert atmosphere at -24 °C for several months without significant degradation.
An efficient F-18 labeling method for PET study: Huisgen 1,3-dipolar cycloaddition of bioactive substances and F-18-labeled compounds

The Cu(I)-catalyzed, 1,3-dipolar cycloaddition reaction was applied successfully to the synthesis of small, F-18-labeled biomolecules, and an optimal condition was developed for one-pot, two-step reaction without any interim purifications. This technique was employed in various F-18-labeled, 1,2,3-triazole syntheses with high radiochemical yield.
