The Rna-Dependent RNA Polymerase of the Influenza a Virus [PDF]

Future Virology, 2014
The influenza A virus causes a highly contagious respiratory disease that significantly impacts our economy and health. Its replication and transcription is catalyzed by the viral RNA polymerase. This enzyme is also crucial for the virus, because it is involved in the adaptation of zoonotic strains.

Oral GS-441524 derivatives: Next-generation inhibitors of SARS‐CoV‐2 RNA‐dependent RNA polymerase

Frontiers in Immunology, 2022
GS-441524, an RNA‐dependent RNA polymerase (RdRp) inhibitor, is a 1′-CN-substituted adenine C-nucleoside analog with broad-spectrum antiviral activity. However, the low oral bioavailability of GS‐441524 poses a challenge to its anti-SARS-CoV-2 efficacy ...

Emerging SARS-CoV-2 mutation hot spots include a novel RNA-dependent-RNA polymerase variant

Journal of Translational Medicine, 2020
Background SARS-CoV-2 is a RNA coronavirus responsible for the pandemic of the Severe Acute Respiratory Syndrome (COVID-19). RNA viruses are characterized by a high mutation rate, up to a million times higher than that of their hosts.

Inhibitors of an RNA‐dependent DNA polymerase [PDF]

FEBS Letters, 1971
Much interest of late has centered around RNAdirected DNA synthesis. Initially, with the finding of an RNA-dependent DNA polymerase in oncogenic RNA viruses [l-S] and what was described as the exclusive presence of the polymerase in acute leukemia cells as opposed to ‘normal’ cells [6] , speculation as to a molecular basis for leukemogenesis and a ...

The antiviral compound remdesivir potently inhibits RNA-dependent RNA polymerase from Middle East respiratory syndrome coronavirus

Journal of Biological Chemistry, 2020
Antiviral drugs for managing infections with human coronaviruses are not yet approved, posing a serious challenge to current global efforts aimed at containing the outbreak of severe acute respiratory syndrome–coronavirus 2 (CoV-2).

Structure of the RNA-dependent RNA polymerase of poliovirus [PDF]

Structure, 1997
The central player in the replication of RNA viruses is the viral RNA-dependent RNA polymerase. The 53 kDa poliovirus polymerase, together with other viral and possibly host proteins, carries out viral RNA replication in the host cell cytoplasm. RNA-dependent RNA polymerases comprise a distinct category of polymerases that have limited sequence ...

Cell penetrable humanized-VH/V(H)H that inhibit RNA dependent RNA polymerase (NS5B) of HCV. [PDF]

PLoS ONE, 2012
NS5B is pivotal RNA dependent RNA polymerase (RdRp) of HCV and NS5B function interfering halts the virus infective cycle. This work aimed to produce cell penetrable humanized single domain antibodies (SdAb; VH/V(H)H) that interfere with the RdRp activity.

SARS-CoV-2 RNA dependent RNA polymerase (RdRp) targeting: an in silico perspective

Journal of Biomolecular Structure and Dynamics, 2020
New treatment against SARS-CoV-2 now is a must. Nowadays, the world encounters a huge health crisis by the COVID-19 viral infection. Nucleotide inhibitors gave a lot of promising results in terms of its efficacy against different viral infections.
