Celgosivir is more effective (IC50=20 μM) than the parent molecule (IC50=254 μM) at causing the accumulation of glucosylated oligosaccharides in HIV-infected cells by inhibition of glycoprotein processing. Celgosivir exhibits potent antiviral activity against HIV-1 with an IC50 of 2.0±2.3 μM[1]. Bovine viral diarrhoea virus (BVDV) is a closely related virus of hepatitis C virus (HCV). Celgosivir inhibits BVDV with IC50 values of 16 and 47 μM in plaque assay and cytopathic effect assay, respectively[2]. Celgosivir inhibits DENV2 replication with an EC50 of 0.2 μM. The EC50 values against DENV1, 3 and 4 are less than 0.7 μM[3].

Protocol
The cytotoxicity of Celgosivir is measured by the Cell titer-Glo Luminescent cell viability assay. The luminescence signals for cells treated with the test compounds are compared to those for cells treated with the maximum tolerated DMSO to determine the 50% cytotoxic concentration[3].

Mice: To model ADE, mice are injected i.p. with 20 μg /mouse of mouse monoclonal antibody against DENV E protein one day prior to infection. For treatment during infection, celgosivir (50 mg/kg) is injected i.p. twice daily for 5 days, starting from day 0, 1 or 2. Blood is collected at days 1, 3 and 7 by submandibular bleeding. Survival of mice is followed until day 10 and survival curves are plotted[3].
