PYRROC is the first functionalized cycloalkyne which cannot form isomers in the strain-promoted cycloaddition with azides, and displays unprecedented rate accelerations and rate constants in aqueous buffer.
Real-time enzymatic studies are gaining importance as their chemical and technical instrumentation improves. Here we report the efficient synthesis of gamma-alkyne modified triphosphate amidates that are converted into a variety of gamma-fluorophore labeled triphosphates by Cu(I) catalyzed alkyne/azide click reactions. The synthesized triphosphates are incorporated into DNA by DNA polymerases.

Fluorescent nucleoside triphosphates are powerful probes of DNA synthesis, but their potential use in living animals has been previously underexplored. Here, we report the synthesis and characterization of 7-deaza-(1,2,3-triazole)-2′-deoxyadenosine-5′-triphosphate (dATP) derivatives of tetramethyl rhodamine (“TAMRA-dATP”), cyanine (“Cy3-dATP”), and boron-dipyrromethene (“BODIPY-dATP”).

Based on the intracellular CCR9 antagonist vercirnon, we developed the first small-molecule-based fluorescentligand targeting the intracellularallostericbindingsite (IABS) of a GPCR. This tool enabled binding studies via NanoBRET, fluorescence microscopy, and the discovery of a new intracellular CCR9 antagonist with improved affinity. To induce CCR9 degradation, we developed the first PROTAC targeting
