Cryo-EM structures of Nipah virus polymerases and high-throughput RdRp assay development enable anti-NiV drug discovery.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Transcription and replication of the Nipah virus (NiV) are driven by the large protein (L) together with its essential co-factor phosphoprotein (P). L encodes all the viral enzymatic functions, including RNA-dependent RNA polymerase (RdRp) activity, while the tetrameric P is multi-modular. Here, we investigate the molecular mechanism of the NiV polymerase and build tools for anti-NiV drug discovery. We analyze and compare multiple cryo-EM structures of both full-length and truncated NiV polymerases from the Malaysia and Bangladesh strains. We identify two conserved loops in the polyribonucleotidyltransferase (PRNTase) domain of L and the binding between RdRp-PRNTase and CD domains. To further assess the mechanism of NiV polymerase activity, we establish a highly sensitive radioactive-labeled RNA synthesis assay and identify a back-priming activity in the NiV polymerase as well as a fluorescence and luminescent-based non-radioactive polymerase assay to enable high-throughput screening for L protein inhibitors. The combination of structural analysis and the development of both high-sensitive and high-throughput biochemical assays will enable the identification of new direct-acting antiviral candidates for treating highly pathogenic henipaviruses.
