4′‐ThioRNA was broadly tolerated across multiple positions in SARS‐CoV‐2‐targeting siRNAs, but full 4'‐thio modification of both strands caused a reduction in RNAi activity. Sense‐strand segmentation improved RNAi and antiviral activity, particularly when the nick was located at position 10 from the 5′‐end of the sense strand, thereby unlocking the ...

Architecture of a SARS-CoV-2 mini replication and transcription complex
SARS-CoV-2 virus replication and transcription is mediated by the replication and transcription complex (RTC) that is composed of 16 non-structural proteins (nsp). Here, the authors present the cryo-EM structure of a SARS-CoV-2 mini RTC consisting of the

Widespread mitovirus sequences in plant genomes [PDF]
The exploration of the evolution of RNA viruses has been aided recently by the discovery of copies of fragments or complete genomes of non-retroviral RNA viruses (Non-retroviral Endogenous RNA Viral Elements, or NERVEs) in many eukaryotic nuclear genomes.

Hitting Coronaviruses Where It Hurts: Antiviral Strategies Targeting Viral Proteins
Viral proteins represent key vulnerabilities in human coronaviruses (HCoVs). This review outlines inhibitors targeting spike (S), main protease (Mpro), papain‐like protease (PLpro), and RNA‐dependent RNA polymerase (RdRp), mapping chemically diverse strategies that disrupt entry and replication, and provides an integrated view of current candidates ...

Influenza A virus pandemics pose a persistent global health threat, and emerging antiviral resistance underscores the critical importance of developing novel broad-spectrum therapeutic agents. Building on licorice’s (Glycyrrhiza spp.) historical use in traditional Chinese medicine for respiratory infections—as documented in the Chinese Guidelines for ...

Topoisomerase IIα promotes activation of RNA polymerase I transcription by facilitating pre-initiation complex formation [PDF]
Type II DNA topoisomerases catalyse DNA double-strand cleavage, passage and re-ligation to effect topological changes. There is considerable interest in elucidating topoisomerase II roles, particularly as these proteins are targets for anti-cancer drugs.

Sigma‐1 Receptor‐Targeting Compounds Show Antiviral Activity Across Multiple Coronavirus Models
ABSTRACT Over the past two decades, coronaviruses have caused three major public health crises, including the epidemics of SARS‐CoV, MERS‐CoV, and SARS‐CoV‐2. Following the outbreak of SARS‐CoV‐2, several antiviral drugs have been approved for the treatment of COVID‐19.

Crystal Structure of the full-length Japanese encephalitis virus NS5 reveals a conserved methyltransferase-polymerase interface. [PDF]
The flavivirus NS5 harbors a methyltransferase (MTase) in its N-terminal ≈ 265 residues and an RNA-dependent RNA polymerase (RdRP) within the C-terminal part.
