    The need for antiviral drugs is real and relevant. Broad spectrum antiviral drugs have a particular advantage when dealing with rapid disease outbreaks, such as the current COVID-19 pandemic. Since viruses are completely dependent on internal cell mechanisms, they must cross cell membranes during their lifecycle, creating a dependence on processes involving membrane dynamics. Thus, in this study we examined whether the synthesis of glycosphingolipids, biologically active components of cell membranes, can serve as an antiviral therapeutic target. We examined the antiviral effect of two specific inhibitors of GlucosylCeramide MESHD synthase (GCS); (i) Genz-123346, an analogue of the FDA-approved drug Cerdelga(R), (ii) GENZ-667161, an analogue of venglustat which is currently under phase III clinical trials. We found that both GCS inhibitors inhibit the replication of four different enveloped RNA viruses of different genus, organ-target and transmission TRANS route: (i) Neuroinvasive Sindbis virus (SVNI), (ii) West Nile virus (WNV), (iii) Influenza A virus, and (iv) SARS-CoV-2. Moreover, GCS inhibitors significantly increase the survival rate of SVNI-infected MESHD mice. Our data suggest that GCS inhibitors can potentially serve as a broad-spectrum antiviral therapy and should be further examined in preclinical and clinical trial. Analogues of the specific compounds tested have already been studied clinically, implying they can be fast-tracked for public use. With the current COVID-19 pandemic, this may be particularly relevant to SARS-CoV-2 infection MESHD. One Sentence SummaryAn analogue of Cerdelga(R), an FDA-approved drug, is effective against a broad range of RNA-viruses including the newly emerging SARS-CoV-2.

    Background: As the outbreak of COVID-19 has accelerated, an urgent need for finding strategies to combat the virus is growing. Results from in vitro studies suggest that a combination of IFN type I and Type II MESHD may be effective against SARS-CoV MESHD. The aim of this study is to investigate the efficacy of treatment with a recombinant IFN alpha 2b and gamma, provided with standard protocol (Kaletra (lopinavir-ritonavir 200/50 mg; 200/100 mg every 12 hour for 30 days; Chloroquine (250 mg) every 12 hours for 10 days) for COVID-19 patients, compared to standard protocol (IFN alpha 2b/Kaletra/Chloroquine) for COVID-19 hospitalized patients, positive diagnosed for SARS-Cov-2. Methods: Hospitalized adult TRANS patients with qPCR confirmed SARS-Cov-2 will be enrolled in this open-labeled, single center, prospective, randomized and controlled clinical trial. One hundred and twenty eligible patients with confirmed SARS-CoV-2 positivity by qPCR amplification in oropharyngeal/nasopharyngeal swab samples will be enrolled at “Luis Diaz Soto” Hospital, Havana, Cuba. The primary outcomes are the time to 2019-nCoV RNA negativity in patients and the time until progression to severe COVID-19. Discussion: This will be the first randomized controlled trial of a potential treatment for SARC-Cov-2 using the combinations of IFNs. Trial registration: The study is sponsored by Center for Genetic and Biotechnology and Ministry of Health of Cuba and was duly registered April 2020 at Enrolment for this study began in April 11, 2020, and has enrolled one hundred patients as of May-26-2020
