Effect Of Dipterinyl Calcium Pentahydrate On Hepatitis B Virus Replication In Transgenic Mice, P Moheno, John D. Morrey, D Fuchs
Effect Of Dipterinyl Calcium Pentahydrate On Hepatitis B Virus Replication In Transgenic Mice, P Moheno, John D. Morrey, D Fuchs

Dipterinyl calcium pentahydrate (DCP) has previously been shown to inhibit MDA-MB-231 human breast cancer xenographs in nude mice in a manner correlated with increases in plasma IL-12 and IL-4 concentrations, and decreases in plasma IL-6 levels. DCP also inhibits indoleamine 2,3-dioxygenase (IDO), an immuno-inhibitory enzyme, in human PBMCs (Peripheral Blood Mononuclear Cells).

A number of RNA viruses cause viral hemorrhagic fever (VHF), in which proinflammatory mediators released from infected cells induce increased permeability of the endothelial lining of blood vessels, leading to loss of plasma volume, hypotension, multi-organ failure, shock and death. The optimal treatment of VHF should therefore include both the use of antiviral drugs to inhibit viral replication and measures to prevent or correct changes in vascular function. Although rodent models have been used to evaluate treatments for increased vascular permeability (VP) in bacterial sepsis, such studies have not been performed for VHF.
Development Of A New Tacaribe Arenavirus Infection Model And Its Use To Explore Antiviral Activity Of A Novel Aristeromycin Analog, B B. Gowen, M H. Wong, D Larson, W Ye, K H. Jung, E J. Sefing, R Skirpstunas, D F. Smee, John D. Morrey, S W. Schneller

A growing number of arenaviruses can cause a devastating viral hemorrhagic fever (VHF) syndrome. They pose a public health threat as emerging viruses and because of their potential use as bioterror agents. All of the highly pathogenic New World arenaviruses (NWA) phylogenetically segregate into clade B and require maximum biosafety containment facilities for their study. Tacaribe virus (TCRV) is a nonpathogenic member of clade B that is closely related to the VHF arenaviruses at the amino acid level. Despite this relatedness, TCRV lacks the ability to antagonize the host interferon (IFN) response, which likely contributes to its inability to cause …
Effects Of The Combination Of Favipiravir (T-705) And Oseltamivir On Influenza A Virus Infections In Mice, D F. Smee, B L. Hurst, M H. Wong, K W. Bailey, E B. Tarbet, John D. Morrey, Y Furuta
Effects Of The Combination Of Favipiravir (T-705) And Oseltamivir On Influenza A Virus Infections In Mice, D F. Smee, B L. Hurst, M H. Wong, K W. Bailey, E B. Tarbet, John D. Morrey, Y Furuta

Favipiravir (T-705 [6-fluoro-3-hydroxy-2-pyrazinecarboxamide]) and oseltamivir were combined to treat influenza virus A/NWS/33 (H1N1), A/Victoria/3/75 (H3N2), and A/Duck/MN/1525/81 (H5N1) infections. T-705 alone inhibited viruses in cell culture at 1.4 to 4.3 µM. Oseltamivir inhibited these three viruses in cells at 3.7, 0.02, and 0.16 µM and in neuraminidase assays at 0.94, 0.46, and 2.31 nM, respectively. Oral treatments were given twice daily to mice for 5 to 7 days starting, generally, 24 h after infection. Survival resulting from 5 days of oseltamivir treatment (0.1 and 0.3 mg/kg/day) was significantly better in combination with 20 mg/kg of body weight/day of T-705 against …
