Inhibition of interferon signaling by dengue virus.
Dengue virus is a worldwide-distributed mosquito-borne flavivirus with a positive strand RNA genome. Its transcribed polyprotein is cleaved by host- and virus-encoded peptidases into 10 proteins, some of which are of unknown function. Although dengue virus-infected cells seem to be resistant to the antiviral action of IFN, the viral products that mediate this resistance are unknown. Therefore, ...
متن کاملInhibition of dengue virus replication by amantadine hydrochloride.
The effect of amantadine hydrochloride (1-adamantanamine hydrochloride) on dengue virus replication was examined in vitro. Amantadine decreased the titers of all four types of dengue viruses grown in LLC-MK2 cells by greater than 90% at concentrations of 50 micrograms/ml. There was no evidence for any cytopathic effect of the drug at concentrations less than 100 micrograms/ml. Studies of the ti...
متن کاملInhibition of dengue virus RNA synthesis by an adenosine nucleoside.
We recently reported that (2R,3R,4R,5R)-2-(4-amino-pyrrolo[2,3-d]pyrimidin-7-yl)-3-ethynyl-5-hydroxy-methyl-tetrahydro-furan-3,4-diol is a potent inhibitor of dengue virus (DENV), with 50% effective concentration (EC(50)) and cytotoxic concentration (CC(50)) values of 0.7 microM and >100 microM, respectively. Here we describe the synthesis, structure-activity relationship, and antiviral charact...
متن کاملDengue virus cross-reactive hemagglutination inhibition antibody responses in patients with primary dengue virus infection.
Acute and convalescent plasma samples were obtained from 101 confirmed primary dengue cases: 48 cases infected with dengue virus type 1, 10 cases with type 2, 42 cases with type 3 and one case with type 4. The hemagglutination inhibition (HI) titers of individual samples were at levels similar to each of the 4 dengue viruses at both the acute and convalescent stages, irrespective of the dengue ...
متن کاملInhibition of dengue virus through suppression of host pyrimidine biosynthesis.
Viral replication relies on the host to supply nucleosides. Host enzymes involved in nucleoside biosynthesis are potential targets for antiviral development. Ribavirin (a known antiviral drug) is such an inhibitor that suppresses guanine biosynthesis; depletion of the intracellular GTP pool was shown to be the major mechanism to inhibit flavivirus. Along similar lines, inhibitors of the pyrimid...
