A Reactive Antagonist Strategy: Cysteine-Directed Covalent Molecular Glue in Plant Hormone Receptor Regulation.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. 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
Controlling protein-protein interactions (PPIs) remains a challenge in modern chemistry. In plants, jasmonoyl-L-isoleucine (JA-Ile) acts as a molecular glue that facilitates PPIs between the F-box protein COI1 and JAZ repressors, leading to transcriptional reprogramming. However, the functional redundancy of JAZ proteins complicates biological studies. To overcome this, we introduce a reactive antagonist (RA) strategy that selectively induces COI1-JAZ interactions for a Cys-mutated JAZ mutant while inhibiting interactions with wild-type JAZs. We designed and synthesized COR-oxime derivatives, identifying O-bromo-ethyl COR-oxime as an optimal RA, functioning as a Cys-directed covalent molecular glue. Mass spectrometry and fluorescence anisotropy assays confirmed its selective covalent binding to Cys-mutated JAZ1, leading to targeted degradation in Arabidopsis. This strategy enables precise functional dissection of JAZ subtypes without affecting endogenous pathways. Given the genetic redundancy in many biological systems, the RA strategy provides a powerful chemical biology tool for dissecting complex signaling networks beyond plant hormone research.
