detectable trehalose analogues have gained attention as probes for studying trehalose metabolism and as potential diagnostic imaging agents for mycobacterial infections. Of particular interest are deoxy-[18F]fluoro-D-trehalose (18F-FDTre) analogues, which have been suggested as possible positron emission tomography (PET) probes for in vivo imaging of M. tuberculosis infection. Here, we report progress

A novel class of cannabinoid ligands was synthesized in good overall yields by means of oxime-bio-conjugation between hydroxylamine-functionalized Rimonabant-type pyrazoles and fluoro-deoxy-carbohydrates (D-2-fluoro-deoxy-glucose, FDG, and D-5-fluoro-5-deoxy-ribose, FDR). FDR proved to be superior to FDG for bio-conjugation, as it occurred in milder conditions and at faster rate (rt, 20 min vs. 100 degrees C, 30 min). All of the title compounds showed relatively modest affinity for the CBI receptor (high nanomolar range) and selectivities vs. the CB2. (C) 2013 Elsevier B.V. All rights reserved.

commercially available radiotracer 2-deoxy-2-[18F]fluoro-d-glucose ([18F]-2-FDG) into the target radioprobe [18F]-2-FDTre in a single step; both manual and automated syntheses were performed with similar results. Cellular uptake experiments showed that radiosynthetic [18F]-2-FDTre was metabolized by Mycobacterium smegmatis but not by various mammalian cell lines, pointing to the potential future use of this
