Controlled reversible methionine-selective sulfimidation of peptides.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Site-selective chemical peptide manipulation is an effective strategy to understand and regulate structure and function. However, methionine-selective modification remains one of the most difficult challenges in peptide chemistry, with notable limited strategies. In this study, we report a general reversible modification strategy at methionine sites that uses the ruthenium-catalyzed sulfimidation of peptides. This method provides a convenient and effective strategy for late-stage peptide functionalization. The N═S bonds of the conjugates are reduced in the presence of glutathione, resulting the traceless releasing of corresponding peptides and amides. Practical applications are then demonstrated using precise reversible modifications of bioactive peptides, the stapling and linearization of peptides, peptide-drug conjugates, and split-and-pool synthesis. This on/off strategy through methionine-selective and reversible sulfimidation provides a unique tool for peptide chemistry and peptide-based drug discovery.
