Design of a phosphinate-based fluorescent probe for superoxide detection in mouse peritoneal macrophages

Abstract

3′,6′‐Bis(diphenylphosphinyl)fluorescein (PF‐1) was synthesized as a highly selective and sensitive fluorescent probe for imaging O 2.− in living cells. The design strategy for the probe was based on the nucleophilic mechanism of O 2.− to mediate deprotection of this probe to give fluorescein. Upon reaction with O 2.−, the probe exhibits a strong fluorescence response and high selectivity for O 2.− over other reactive oxygen species and some biological compounds. The phosphinate‐based probe, as a new fluorescent reagent, is cell‐permeable and can detect micromolar changes of O 2.− concentrations by using confocal microscopy in living cells. The unique combination of good selectivity, high sensitivity, good water solubility, and rapid reactivity establishes the potential value of the probe for facilitating investigations of the generation, metabolism, and mechanisms of superoxide‐mediated cellular homeostasis and injury.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Fluorescent probes (c) and (d) designed by Tang and co-workers function based on the nucleophilic property of O2•− involved in deprotection of diphenylphosphinate residues attached to a fluorescein probe or a naphthofluorescein probe.

    “The fluorescent probes (c) and (d) were designed by Tang and co-workers, and their functions are based on the nucleophilic property of O2•− which is involved in the deprotection of the diphenylphosphinate residues attached to the fluorescein probe [166] (c), Figure 67, or the naphthofluorescein probe [167] (d).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
