1 · What the graph read from it

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.

2 · The registry

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

Glucagon-like peptide-1 receptor (GLP-1R) ligands including semaglutide play an important role in drug discovery. Herein, a short semaglutide-derived GLP-1R-engaging segment was used as the basis for scaffold construction, and conformational restabilisation was introduced through lactam stapling and bulky aromatic non-natural amino acid substitution. A total of 108 stapled peptide candidates were designed by structure-guided modelling and virtual screening. Among them, 35 peptides were synthesised and characterised. Most stapled analogues showed improved serum and proteolytic stability relative to semaglutide, and 11CP-17B, 11CP-17N, and 11CP-19N showed the most favourable stability profiles. Molecular dynamics simulations and MM-GBSA analysis were consistent with receptor-compatible poses and favourable predicted interaction patterns for these representative analogues. Collectively, these results define a practical strategy for constructing stabilised semaglutide-derived peptide scaffolds and provide a basis for subsequent functional optimisation of GLP-1R-targeting peptides.
