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

We describe structure-based design, synthesis, and biological evaluation of a series of novel inhibitors bearing a pyrazole (compounds 3a-h) or a thiazole moiety (compounds 4a-e) as the P3 ligand. We have also explored Boc-β-amino-l-alanine as a novel P2 ligand. A number of inhibitors have displayed β-secretase inhibitory potency. Inhibitor 4c has shown potent BACE1 inhibitory activity, Ki=0.25nM, cellular EC50 of 194nM, and displayed good selectivity over BACE2. A model of 4c was created based upon the X-ray structure of 2-bound β-secretase which revealed critical interactions in the active site.
