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

LuxS, a conserved bacterial enzyme involved in the activated methyl cycle, catalyzes S-ribosylhomocysteine (SRH) into homocysteine and AI-2 (the inter-species quorum-sensing signal molecule). This enzyme has been reported to be essential for the survival of Actinobacillus pleuropneumoniae in its natural host. Therefore, it is a potential drug target against A. pleuropneumoniae, an important swine respiratory pathogen causing great economic losses in the pig industry worldwide. In this study, the enzymatic activity determination method was established using the recombinant LuxS of A. pleuropneumoniae. Thirty-five compounds similar to the shape of SRH were screened from the Specs compound library by the software vROCS and were evaluated for LuxS inhibition. Three compounds could inhibit LuxS activity. Two of them were confirmed to be competitive inhibitors and the third one was uncompetitive. All the three compounds displayed inhibitory effects on the growth of A. pleuropneumoniae and two other important swine pathogens, Haemophilis parasuis and Streptococcus suis, with MIC50 values ranging from 11 to 51 μg/ml. No significant cytotoxic effect of the compounds was detected on porcine PK-15 cells at the concentration which showed inhibitory effect on bacterial growth. These results suggest that LuxS is an ideal target to develop antimicrobials for porcine bacterial pathogens. The three LuxS inhibitors identified in this study can be used as lead compounds for drug design.
