  The Pennsylvania Green Fluorophore: A Hybrid of Oregon Green and Tokyo Green for the Construction of Hydrophobic and pH-Insensitive Molecular Probes

  摘要：

  Fluorescent small molecules are powerful tools for exploring cellular biology. As a more hydrophobic, photostable, and less pH-sensitive alternative to fluorescein, we synthesized Pennsylvania Green, a bright, monoanionic fluorophore related to Oregon Green and Tokyo Green. Comparison of membrane probes comprising N-alkyl-3 beta-cholesterylamine linked to 4-carboxy-Tokyo Green (pK(a) similar to 6.2) and 4-carboxy-Pennsylvania Green (pK(a) similar to 4.8) revealed that only Pennsylvania Green was highly fluorescent in acidic early and recycling endosomes within living mammalian cells.

  A Concise Synthesis of the Pennsylvania Green Fluorophore and Labeling of Intracellular Targets with O⁶-Benzylguanine Derivatives

  摘要：

  We report improved syntheses of the Pennsylvania Green and 4-carboxy-Pennsylvania Green fluorophores; the latter compound was prepared from methyl 4-iodo-3-methylbenzoate in a three-pot process (32% overall yield). Chinese hamster ovary cells expressing O-6-alkylguanine-DNA alkyltransferase fusion proteins were treated with Pennsylvania Green and Oregon Green linked to O-6-benzyiguanine (SNAP-Tag substrates). Analysis of living cells by confocal microscopy revealed that Pennsylvania Green derivatives exhibit substantially higher cell permeability than analogous Oregon Green-derived molecular probes.

  (CuAAC)) rather than a hydrolyzable oxime bond to attach PLP and LABL to HA. We explored cSAgAPLP:LABL B cell engagement and modulation of BCR-mediated signaling in vitro through flow cytometry binding and calcium flux signaling assays. Indeed, cSAgAPLP:LABL exhibited higher avidity B cell binding and greater dampening of BCR-mediated signaling than hydrolyzable SAgAPLP:LABL. Furthermore, cSAgAPLP:LABL
