Selective Inhibitors of Helicobacter pylori Methylthioadenosine Nucleosidase and Human Methylthioadenosine Phosphorylase.
Article in Journal of medicinal chemistry, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Bacterial 5'-methylthioadenosine/ S-adenosylhomocysteine nucleosidase (MTAN) hydrolyzes adenine from its substrates to form S-methyl-5-thioribose and S-ribosyl-l-homocysteine. MTANs are involved in quorum sensing, menaquinone synthesis, and 5'-methylthioadenosine recycling to S-adenosylmethionine. Helicobacter pylori uses MTAN in its unusual menaquinone pathway, making H. pylori MTAN a target for antibiotic development. Human 5'-methylthioadenosine phosphorylase (MTAP), a reported anticancer target, catalyzes phosphorolysis of 5'-methylthioadenosine to salvage S-adenosylmethionine. Transition-state analogues designed for HpMTAN and MTAP show significant overlap in specificity. Fifteen unique transition-state analogues are described here and are used to explore inhibitor specificity. Several analogues of HpMTAN bind in the picomolar range while inhibiting human MTAP with orders of magnitude weaker affinity. Structural analysis of HpMTAN shows inhibitors extending through a hydrophobic channel to the protein surface. The more enclosed catalytic sites of human MTAP require the inhibitors to adopt a folded structure, displacing the phosphate nucleophile from the catalytic site.
