Proteome-wide ligandability maps of drugs with diverse cysteine-reactive chemotypes.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Covalent drug discovery has experienced a revival since the 2013 approval of the first cysteine-targeting kinase inhibitors. Many drugs that were discovered by serendipity also possess the ability to react with cysteine residues, leading to interactions with multiple proteins. This widespread interaction, known as promiscuity, necessitates a comprehensive study of how these drugs engage with cysteines throughout the proteome. Here we report a large-scale analysis to meet this need by defining proteome-wide cysteine ligandability maps of 70 drugs in native biological systems. We examined over 24,000 cysteines in the human proteome, pinpointing 279 proteins as potential drug targets across diverse functional categories. We further validated several cysteine engagement events, uncovering previously unknown cysteine sites on both established drug targets and proteins that are generally difficult to address with small molecules. Additionally, our findings highlighted an opportunity to harness a drug-cysteine interaction for targeted protein degradation. Together, our analysis provides an invaluable resource for advancing the development of covalent drugs.
