Identification of a receptor tyrosine kinase inhibitor CP-724714 inhibits SADS-CoV related swine diarrhea coronaviruses infection in vitro.
Article in Virologica Sinica, 2023. 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
The outbreak of the COVID-19 epidemic in 2020 has caused unprecedented panic among all mankind, pointing the major importance of effective treatment. Since the emergence of the swine acute diarrhea syndrome coronavirus (SADS-CoV) at the end of 2017, multiple reports have indicated that the bat-related SADS-CoV possesses a potential threat for cross-species transmission. Vaccines and antiviral drugs development deserve more attention. In this study, we found that the HER2 phosphorylation inhibitor (CP-724714) inhibited SADS-CoV infection in a dose-dependent manner. Further validation demonstrated that CP-724714 affected at the post-entry stage of SADS-CoV infection cycle. Also, efficient SADS-CoV infection required the activation of HER2 and its cascade Ras-Raf-Mek-Erk signaling pathway. In addition, CP-724714 has a broad-spectrum anti-swine diarrhea coronaviruses activity, and can dose-dependently combat SADS-CoV, porcine epidemic diarrhea virus (PEDV), porcine deltacoronavirus (PDCoV) and transmissible gastroenteritis virus (TGEV) infection in vitro with a specificity index of greater than 21.98, 9.38, 95.23 and 31.62, respectively. These results highlight the potential utility of CP-724714 or antiviral drugs targeting with HER2 and its cascade Ras-Raf-Mek-Erk signaling pathway as host-targeted SADS-CoV and other related coronaviruses therapeutics.
