Selective inhibition of Mycobacterium tuberculosis GpsI unveils a novel strategy to target the RNA metabolism.
Article in Nucleic acids research, 2025. 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
Polyribonucleotide nucleotidyl-transferases (PNPases) play a critical role in the degradation of mRNA. The mycobacterial PNPase, guanosine penta-phosphate synthase I (GpsI), is an essential enzyme in Mycobacterium tuberculosis (Mtb), collaborating with endoribonucleases and helicases to process RNA. In this study, we identify GpsI as a novel and underexplored drug target. The inhibitor 1-(4'-(2-phenyl-5-(trifluoromethyl) oxazole-4-carboxamido)-[1,1'-biphenyl]-4-caroxamido) cyclopentane-1-carboxylic acid (X1), discovered through a whole-cell screening, specifically inhibits GpsI activity in biochemical assays. Biochemical and physiological analyses of engineered GpsI variants and recombinant Mycobacterium smegmatis pinpoint amino acids 328 and 527 as critical residues for the selective activity of X1 against Mtb complex. High-resolution cryo-electron microscopy analysis of the ternary GpsI-X1-poly(A) complex elucidates the drug-binding pocket, providing insight into its mechanism of action. This study introduces a potent inhibitor targeting the underexplored Mtb-GpsI and offers a molecular explanation for its selective specificity.
