    TLDR Six existing drugs may help block virus entry in COVID-19.
    The study identified six compounds—cepharanthine, abemaciclib, osimertinib, trimipramine, colforsin, and ingenol—as broad-spectrum inhibitors of spike-mediated entry of SARS-CoV-2, SARS-S, and MERS-S pseudotyped particles. These findings were based on a high throughput screen of an approved drugs library. The research aimed to contribute to the development of effective treatments against the initial stage of viral infection, potentially reducing the viral burden in COVID-19 patients. The authors declared no competing interests, and the work was supported by various institutions and foundations.
