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

backgroundA recent report showed that Stephania japonica chloroform fraction has potential anticholinesterase and antioxidant activities and is able to improve learning and memory in mice. Therefore, the aim of the present study was to isolate and identify compounds from the chloroform fraction with cholinesterase inhibitory and antioxidant activity that may be useful as new candidates for the treatment of AD.

methodsChromatographic methods were used for isolation of compounds and the isolated compounds were analyzed by spectroscopic methods for structure elucidation. Acetyl- and butyryl-cholinesterase inhibitory activity were evaluated for by Ellman's method and the antioxidant activity by several in vitro models such as DPPH and hydroxyl radicals scavenging, reducing power, total antioxidant activity, and inhibition of brain lipid peroxidation. The interaction of cholinesterase enzymes and isolated compounds were examined by molecular docking studies.

resultsBioactivity guided approach led to the isolation of four compounds from the chloroform fraction and identified as aknadinine, aknadilactam, aknadicine and stephisoferuline on the basis of their

conclusionThe hasubabanan alkaloids isolated from S. japonica may represent a new class of anti-cholinesterase compounds. The multitargeted activity of hasubanan alkaloids may lead to new candidates for the treatment of AD.
