A high throughput antiviral screening platform for alphaviruses based on Semliki Forest virus expressing eGFP reporter gene.

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
Alphaviruses, which contain a variety of mosquito-borne pathogens, are important pathogens of emerging/re-emerging infectious diseases and potential biological weapons. Currently, no specific antiviral drugs are available for the treatment of alphaviruses infection. For most highly pathogenic alphaviruses are classified as risk group-3 agents, the requirement of biosafety level 3 (BSL-3) facilities limits the live virus-based antiviral study. To facilitate the antiviral development of alphaviruses, we developed a high throughput screening (HTS) platform based on a recombinant Semliki Forest virus (SFV) which can be manipulated in BSL-2 laboratory. Using the reverse genetics approach, the recombinant SFV and SFV reporter virus expressing eGFP (SFV-eGFP) were successfully rescued. The SFV-eGFP reporter virus exhibited robust eGFP expression and remained relatively stable after four passages in BHK-21 cells. Using a broad-spectrum alphavirus inhibitor ribavirin, we demonstrated that the SFV-eGFP can be used as an effective tool for antiviral study. The SFV-eGFP reporter virus-based HTS assay in a 96-well format was then established and optimized with a robust Z' score. A section of reference compounds that inhibit highly pathogenic alphaviruses were used to validate that the SFV-eGFP reporter virus-based HTS assay enables rapid screening of potent broad-spectrum inhibitors of alphaviruses. This assay provides a safe and convenient platform for antiviral study of alphaviruses.
