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

In this study, the efficient design and synthesis of a novel peptide bioisosteres for selective folding into a hairpin-like structure has been reported. The peptide mimetic comprises β-alanine, L-leucine, α-amino isobutyric acid, m-nitro cinnamic acid has been synthesized via solution-phase coupling methods. A hairpin conformation and extended β-pleated parallel sheet assembly have been characterized in solution as well as in solid state. The key to this success was the use of β-alanine as a flexible amino acid that can accommodate a wide range of dihedral angles proximal to the binol core. In its solid state, the molecule adopts a hairpin conformation with two perpendicular naphthalene rings. The centrally located binol segment act as bioisosteres and nucleates a chain reversal in the hairpin conformation. Two intramolecular cross-strand hydrogen bonds stabilize the hairpin. Moreover, the intermolecular NH…O═C hydrogen bonds connect the hairpins into an infinitely extended parallel β-sheet. The structure is also stabilized by face to edge π-stacking interactions. This peptide bioisosteres represents a promising tool for foldamer design.
