Antiangiogenic Activity of 6-O-Desulfated Modified Heparin: Suppression of Choroidal Neovascularization.

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
Age-related macular degeneration (AMD) is a leading cause of irreversible blindness worldwide, primarily due to pathological choroidal neovascularization (CNV). Our study investigates a chemically modified heparin derivative as a novel strategy to selectively modulate angiogenic signaling, offering a reduced anticoagulant risk and preclinical support for AMD treatment. We explored the therapeutic potential of 6-O-desulfated heparin (Hep-6Od) as an antiangiogenic agent with diminished anticoagulant activity. Synthesized via selective 6-O-desulfation and characterized using nuclear magnetic resonance (NMR), Hep-6Od demonstrated safety in retinal pigment epithelial cells with no cytotoxic effects at various concentrations. In vitro, the compound significantly inhibited endothelial cell proliferation, migration, and capillary tube formation. Differential scanning fluorimetry (DSF) assays confirmed molecular interaction between Hep-6Od and fibroblast growth factor 2 (FGF-2), suggesting interference with pro-angiogenic signaling pathways. In vivo, a laser-induced CNV model in lean Zucker rats showed a dose-dependent reduction in neovascular lesion areas after an intravitreal Hep-6Od injection. Compared to unfractionated heparin, Hep-6Od exhibited reduced anticoagulant effects in PT and aPTT assays while maintaining robust antiangiogenic properties. These findings support Hep-6Od as a promising alternative to anti-vascular endothelial growth factor (VEGF) therapies for AMD treatment, potentially expanding current retinal vascular disease interventions. The results underscore its potential to transform AMD management, pending further clinical validation and awaiting confirmation in further studies.
