Cycloimidamicins, Novel natural lead compounds for translation inhibition in Pseudomonas aeruginosa.
Article in The Journal of antibiotics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Pseudomonas aeruginosa is one of the most concerning pathogenic bacteria. We screened antibiotics using a highly drug-sensitive P. aeruginosa strain and an oligotrophic medium, and successfully isolated novel antibiotics, namely cycloimidamicins (CIMs), from a rare actinomycete strain, Lentzea sp. MM249-143F7. X-ray and nuclear magnetic resonance analyses revealed that CIMs possess a distinctive and unprecedented molecular structure, containing tetramic acid and an imidazole ring bound directly to indolone. The CIMs exhibited potent antibacterial activity against Gram-negative bacteria, as well as translation inhibition in Escherichia coli in both intact cells and in vitro. Additionally, E. coli strains resistant to known translation inhibitors did not exhibit cross-resistance to CIMs, suggesting that CIMs inhibit bacterial growth by blocking translation through a novel mechanism.
