1 · What the graph read from it

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.

2 · The registry

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

objectivesUsing strategy of drug repurposing, antiviral agents against influenza A virus (IAV) and newly emerging SARS-coronavirus 2 (SARS-CoV-2, also as 2019-nCoV) could be quickly screened out. MATERIALS AND

methodsA previously reported engineered replication-competent PR8 strain carrying luciferase reporter gene (IAV-luc) and multiple pseudotyped IAV and SARS-CoV-2 virus was used. To specifically evaluate the pH change of vesicles containing IAV, we constructed an A549 cell line with endosomal and lysosomal expression of pHluorin2.

resultsHere, we identified azithromycin (AZ) as an effective inhibitor against multiple IAV and SARS-CoV-2 strains. We found that AZ treatment could potently inhibit IAV infection in vitro. Moreover, using pseudotyped virus model, AZ could also markedly block the entry of SARS-CoV-2 in HEK293T-ACE2 and Caco2 cells. Mechanistic studies further revealed that such effect was independent of interferon signalling. AZ treatment neither impaired the binding and internalization of IAV virions, nor the viral replication, but rather inhibited the fusion between viral and vacuolar membranes. Using a NPC1-pHluorin2 reporter cell line, we confirmed that AZ treatment could alkalize the vesicles containing IAV virions, thereby preventing pH-dependent membrane fusion.

conclusionsOverall, our findings demonstrate that AZ can exert broad-spectrum antiviral effects against IAV and SARS-CoV-2, and could be served as a potential clinical anti-SARS-CoV-2 drug in emergency as well as a promising lead compound for the development of next-generation anti-IAV drugs.
