Compound K14 inhibits bacterial killing and protease activity in Dictyostelium discoideum phagosomes.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Phagocytic cells of the mammalian innate immune system play a critical role in protecting the body from bacterial infections. The multiple facets of this encounter (chemotaxis, phagocytosis, destruction, evasion and pathogenicity) are largely recapitulated in the phagocytic amoeba Dictyostelium discoideum. Here we identified a new chemical compound (K14; ZINC19168591) which inhibited intracellular destruction of ingested K. pneumoniae in D. discoideum cells. Concomitantly, K14 reduced proteolytic activity in D. discoideum phagosomes. In kil1 KO cells, K14 lost its ability to inhibit phagosomal proteolysis and to inhibit intra-phagosomal bacterial destruction, suggesting that K14 inhibits a Kil1-dependent protease involved in bacterial destruction. These observations stress the key role that proteases play in bacterial destruction. They also reveal an unsuspected link between Kil1 and phagosomal proteases. K14 can be used in the future as a tool to probe the role of different proteases in phagosomal physiology and in the destruction of ingested bacteria.
