First, an Hsp90 inhibitor, 17-AAG, significantly suppressed MERS-CoV propagation in cell lines and physiological-relevant human intestinal organoids. SARS-CoV and SARS-CoV-2. Collectively, Hsp90 is usually a host dependency factor for human coronavirus MERS-CoV, SARS-CoV and SARS-COV-2. Hsp90 inhibitors can be repurposed as a Benazepril HCl potent and broad-spectrum antiviral against human coronaviruses. test was used for data analysis. ***test was used for data analysis. ***test was used for data analysis. ***test was used for data analysis. ***prediction, Hsp90 inhibitors could be used to treat COVID-19 [31]. Herein, we provide the experimental evidence that 17-AAG potently suppressed the replication of SARS-CoV-2 and SARS-CoV (Physique 6), which highlights the potential of targeting Hsp90 as a promising therapeutic strategy against SARS-CoV-2. It is believed that Hsp90 may recognize a metastable structural element in client proteins rather than a primary amino acid motif [17]. Thus, Hsp90 inhibitor-mediated suppression of SARS-CoV-2 and SARS-CoV is usually readily expected, although the Benazepril HCl amino acid homology of MERS-CoV NP with SARS-CoV-2 NP and SARS-CoV NP is around 50%. Nevertheless, the viral target(s) of Hsp90 in SARS-CoV-2 and SARS-CoV definitely requires further investigation. Similar to the virus-infected cells, highly proliferative cancer cells show a higher dependency on cellular chaperones than normal cells to prevent the toxic effects of intracellular protein misfolding and aggregation. As such, several pharmacological Hsp90 inhibitors have been developed, some of which have been in advanced clinical trials for cancer treatment [32]. These inhibitors could be repurposed as a novel class of antivirals to treat COVID-19. Up to now, there is no approved antiviral treatment for human coronavirus infections. As far as we know, 17-AAG-mediated inhibition is usually more potent than most reported anti-coronaviruses brokers [33,34], if not all. Our study exhibited the essential role of Hsp90 for replication of human coronaviruses. Thus, temporary inhibition of Hsp90 may represent a promising therapeutic strategy against human coronavirus infections.
