A Small-Molecule Inhibitor of Gut Bacterial Urease Protects the Host from Liver Injury.
Article in ACS chemical biology, 2025. 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
Hyperammonemia is characterized by the accumulation of ammonia within the bloodstream upon liver injury. Left untreated, hyperammonemia contributes to conditions such as hepatic encephalopathy that have high rates of patient morbidity and mortality. Previous studies have identified gut bacterial urease, an enzyme that converts urea into ammonia, as a major contributor to systemic ammonia levels. Here, we demonstrate use of benurestat, a clinical candidate used against ureolytic organisms in encrusted uropathy, to inhibit urease activity in gut bacteria. Benurestat inhibits ammonia production by urease-encoding gut bacteria and is effective against individual microbes and complex gut microbiota. When administered to conventional mice with liver injury induced by thioacetamide exposure, benurestat reduced gut and serum ammonia levels and rescued 100% of mice from lethal acute liver injury. Overall, this study provides an important proof-of-concept for modulating host ammonia levels and microbiota-driven risks for hyperammonemia with gut microbiota-targeted small-molecule inhibitors.
