Here we show that clofazimine—an anti-leprosy drug with favourable safety profile3—possesses inhibitory activity against several coronaviruses, can antagonize replication SARS-CoV-2 MERS-CoV range vitro systems. We found molecule, which has been...
Abstract The emergence of novel SARS coronavirus 2 (SARS-CoV-2) in 2019 has triggered an ongoing global pandemic severe pneumonia-like disease designated as (COVID-19). To date, more than 2.1 million confirmed cases and 139,500 deaths have been reported worldwide, there are currently no medical countermeasures available to prevent or treat the disease. As development a vaccine could require at least 12-18 months, typical timeline from hit finding drug registration antiviral is >10 years,...
Abstract The emergence of SARS-CoV-2 variants concern and repeated outbreaks coronavirus epidemics in the past two decades emphasize need for next-generation pan-coronaviral therapeutics. Drugging multi-functional papain-like protease (PLpro) domain viral nsp3 holds promise. However, none known PLpro inhibitors has been shown to be vivo active. Herein, we screened a structurally diverse library 50,080 compounds potential identified noncovalent lead inhibitor F0213 that broad-spectrum...
A cross-lineage therapeutic antibody potently targets the receptor binding site of influenza B virus via multiple mechanisms.
The ongoing Coronavirus Disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) signals an urgent need for expansion in treatment options. In this study, we investigated the anti-SARS-CoV-2 activities of 22 antiviral agents with known broad-spectrum against coronaviruses and/or other viruses. They were first evaluated our primary screening VeroE6 cells and then most potent further using viral antigen expression, load reduction, plaque reduction...
Effective treatments for coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome 2 (SARS-CoV-2) are urgently needed. Dexamethasone has been shown to confer survival benefits certain groups of hospitalized patients, but whether glucocorticoids such as dexamethasone and methylprednisolone should be used together with antivirals prevent a boost SARS-CoV-2 replication remains determined. Here, we show the beneficial effect alone in combination remdesivir hamster model...
Host AP2M1 protein is exploited by diverse pathogenic viruses via their YxxØ motif during viral replication cycle.
Coronavirus Disease 2019 (COVID-19) is predominantly a respiratory tract infection that significantly rewires the host metabolism. Here, we monitored cohort of COVID-19 patients' plasma lipidome over disease course and identified triacylglycerol (TG) as dominant lipid class present in severe acute syndrome coronavirus 2 (SARS-CoV-2)-induced metabolic dysregulation. In particular, pinpointed droplet (LD)-formation enzyme diacylglycerol acyltransferase (DGAT) LD stabilizer adipocyte...
Abstract Host survival depends on the elimination of virus and mitigation tissue damage. Herein, we report modulation D-mannose flux rewires virus-triggered immunometabolic response cascade reduces Safe inexpensive can compete with glucose for same transporter hexokinase. Such competitions suppress glycolysis, reduce mitochondrial reactive-oxygen-species succinate-mediated hypoxia-inducible factor-1α, thus virus-induced proinflammatory cytokine production. The combinatorial treatment by...
There are only eight approved small molecule antiviral drugs for treating COVID-19. Among them, four nucleotide analogues (remdesivir, JT001, molnupiravir, and azvudine), while the other protease inhibitors (nirmatrelvir, ensitrelvir, leritrelvir, simnotrelvir-ritonavir). Antiviral resistance, unfavourable drug‒drug interaction, toxicity have been reported in previous studies. Thus there is a dearth of new treatment options SARS-CoV-2. In this work, three-tier cell-based screening was...
