Conformationally Strained trans-Cyclooctene (sTCO) Enables the Rapid Construction of (18)F-PET Probes via Tetrazine Ligation.
The bioorthogonal reaction between tetrazines and trans-cyclooctenes is a method for the rapid construction of F-18 probes for PET imaging. Described here is a second generation (18)F-labeling system based on a conformationally strained trans-cyclooctene (sTCO)-a dienophile that is approximately 2 orders of magnitude more reactive than conventional TCO dienophiles. Starting from a readily prepa...
متن کاملConformationally Strained trans-Cyclooctene with Improved Stability and Excellent Reactivity in Tetrazine Ligation.
Computation has guided the design of conformationally-strained dioxolane-fused trans-cyclooctene (d-TCO) derivatives that display excellent reactivity in the tetrazine ligation. A water soluble derivative of 3,6-dipyridyl-s-tetrazine reacts with d-TCO with a second order rate k2 366,000 (+/- 15,000) M-1s-1 at 25 °C in pure water. Furthermore, d-TCO derivatives can be prepared easily, are access...
متن کاملMechanism‐Based Fluorogenic trans‐Cyclooctene–Tetrazine Cycloaddition
The development of fluorogenic reactions which lead to the formation of fluorescent products from two nonfluorescent starting materials is highly desirable, but challenging. Reported herein is a new concept of fluorescent product formation upon the inverse electron-demand Diels-Alder reaction of 1,2,4,5-tetrazines with particular trans-cyclooctene (TCO) isomers. In sharp contrast to known fluor...
متن کاملPET probes beyond 18F-FDG
During the past several decades, positron emission tomography (PET) has been one of the rapidly growing areas of medical imaging; particularly, its applications in routine oncological practice have been widely recognized. At present, (18)F-fluorodeoxyglucose ((18)F-FDG) is the most broadly used PET probe. However, (18)F-FDG also suffers many limitations. Thus, scientists and clinicians are grea...
متن کاملPretargeted PET Imaging of trans-Cyclooctene-Modified Porous Silicon Nanoparticles
Pretargeted positron emission tomography (PET) imaging based on bioorthogonal chemical reactions has proven its potential in immunoimaging. It may also have great potential in nanotheranostic applications. Here, we report the first successful pretargeted PET imaging of trans-cyclooctene-modified mesoporous silicon nanoparticles, using 18F-labeled tetrazine as a tracer. The inverse electron-dema...
