Advanced Large-Stokes-Shift Fluorescent Probe for the Detection of Biothiols: Facilitating Accurate Indirect Measurement of β-Lactamases.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A novel fluorescent probe, Bibc-DNBS, based on the combination of the PET (photoinduced electron transfer) and ESIPT (excited-state intramolecular proton transfer) mechanisms, was designed and synthesized. Bibc-DNBS exhibited a Stokes shift of 172 nm in the fluorescence detection field. In addition, the probe exhibited good performance in key parameters in bioassays such as sensitivity, specificity, and response time. Based on these properties, Bibc-DNBS successfully monitored the biothiol levels in live cells and zebrafish models, providing an effective analytical tool for real-time monitoring of biothiols. More importantly, Bibc-DNBS could be useful for indirectly detecting β-lactamases. Bibc-DNBS(3-(1H-benzo[d]imidazol-2-yl)-4'-cyano-[1,1'-biphenyl]-4-yl2,4-dinitrobenzenesulfonate) facilitated the screening of β-lactamase inhibitors, using tazobactam and clavulanic acid as model compounds, with respective semi-inhibitory concentration values of 31.32 μM and 2.26 μM, respectively. It might also be applied to distinguish sensitive strain
