Mechanism of Inhibition of Enveloped Virus Membrane Fusion by the Antiviral Drug Arbidol
The broad-spectrum antiviral arbidol (Arb) inhibits cell entry of enveloped viruses by blocking viral fusion with host cell membrane. To better understand Arb mechanism of action, we investigated its interactions with phospholipids and membrane peptides. We demonstrate that Arb associates with phospholipids in the micromolar range. NMR reveals that Arb interacts with the polar head-group of pho...
متن کاملArbidol: a broad-spectrum antiviral compound that blocks viral fusion.
Arbidol (ARB; ethyl-6-bromo-4-[(dimethylamino)methyl]-5-hydroxy-1-methyl-2-[(phenylthio)methyl]-indole-3-carboxylate hydrochloride monohydrate), is a Russian-made potent broad-spectrum antiviral with demonstrated activity against a number of enveloped and non-enveloped viruses. ARB is well known in Russia and China, although to a lesser extent in western countries. Unlike other broad-spectrum a...
متن کاملThe Antiviral Effects of Curcumin Nanomicelles on the Attachment and Entry of Hepatitis C Virus
Background and Aims: Hepatitis C virus (HCV) is a member of the Flaviviridae family, which causes approximately 500,000 deaths annually. HCV infection treatment is often associated with significant adverse effects. Curcumin is an active ingredient of turmeric which has therapeutic anti-inflammatory effects in many diseases including infectious ones. Although curcumin is not soluble in water, if...
متن کاملStructural basis of influenza virus fusion inhibition by the antiviral drug Arbidol.
The broad-spectrum antiviral drug Arbidol shows efficacy against influenza viruses by targeting the hemagglutinin (HA) fusion machinery. However, the structural basis of the mechanism underlying fusion inhibition by Arbidol has remained obscure, thereby hindering its further development as a specific and optimized influenza therapeutic. We determined crystal structures of Arbidol in complex wit...
متن کاملDevelopment of intergenotypic chimeric replicons to determine the broad-spectrum antiviral activities of hepatitis C virus polymerase inhibitors.
To address the need for broad-spectrum antiviral activity characterization of hepatitis C virus (HCV) polymerase inhibitors, we created a panel of intergenotypic chimeric replicons containing nonstructural (NS) protein NS5B sequences from genotype 2b (GT2b), GT3a, GT4a, GT5a, and GT6a HCV isolates. Viral RNA extracted from non-GT1 HCV patient plasma was subjected to reverse transcription. The N...
