Disulfide-rich polysulfur alkaloids target vascular endothelial growth factor A through electronic duality and shape-responsive recognition.

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
Vascular endothelial growth factor A (VEGFA) is a pivotal driver of tumor-induced angiogenesis, yet its flat and featureless interface has long resisted small-molecule intervention. Here, we report the first systematic exploration of disulfide-rich polysulfur alkaloids, lissoclibadins (LCs), as a promising candidate for VEGFA inhibitors. Comprehensive structural, electronic, and molecular dynamics analyses reveal that the sulfur-enriched cores of LCs confer conformational plasticity and electronic duality, enabling shape-responsive recognition of VEGFA loop regions. Quantum chemical descriptors highlight pronounced ambiphilicity at sulfur centers, with LC1, LC4, LC7, and LC8 displaying elongated S-S bonds, low bond strength indices, and high softness, correlating with enhanced reactivity and VEGFA engagement. Docking and simulation studies demonstrate stable binding of selected LCs at VEGFA's flexible loops, reinforced by sulphur-centered hydrogen bonds, dispersion interactions, and persistent hydrogen-bonding networks. Free-energy calculations identify LC7 (ΔH
