Synthesis of New Fluoro-Benzimidazole Derivatives as an Approach towards the Discovery of Novel Intestinal Antiseptic Drug Candidates.
Article in Current pharmaceutical design, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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 the present study, nineteen new fluoro-benzimidazole derivatives, including nifuroxazide analogs, were synthesized by microwave-supported reactions and tested against a panel of pathogenic microorganisms consisting of resistant strains. The synthesized compounds were characterized and identified by FT-IR, 1H- and 13C-NMR, mass spectroscopy, and elemental analyses, respectively. In vitro antimicrobial and cytotoxic effects of the synthesized compounds were determined by microdilution and by [3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide] (MTT) assay. The compound 4-[5(6)-fluoro-1H-benzimidazol-2-yl)-N'-(2- methylbenzylidene)]benzohydrazide (18) showed particularly high inhibitory activity against the gastro-intestinal pathogens, such as Escherichia coli O157:H7, Escherichiacoli ATCC 8739, Escherichia coli ATCC 35218 and Salmonella typhimurium ATCC 13311 standard strains, with minimum inhibitory concentrations (MIC90) ranging from 0.49-0.98 μg/mL. The microbial panel contained a total of ten pathogens including Klebsiella sp., Mycobacterium sp., MRSA, etc., for which the level of inhibitory activity measured was higher than that exhibited by the tested concentrations (MIC > 1000 μg/mL). In vitro cytotoxicity results revealed that the inhibitory concentration (IC50) value (210.23 μg/mL) of compound 18 against CCD 841 CoN cells (human intestinal epithelial cell line) is about 430 times higher than its MIC90 value against the tested Escherichia coli strains. Furthermore, the docking study of compound 18 suggested that its structure is very compatible with the active site pocket of the phosphofructokinase-2 enzyme.
