Non-Polio Enterovirus Inhibitors: Scaffolds, Targets, and Potency─What's New?

Area of Science:

• Virology
• Infectious Diseases
• Drug Discovery

Background:

• Enteroviruses (EVs) are globally prevalent viruses causing various diseases, including hand-foot-mouth disease (HFMD).
• While a vaccine exists for EV-A71 in China, no specific antiviral treatments are currently available for non-polio Enteroviruses (NPEVs).
• There is a critical need for effective antiviral therapies against a wide range of Enterovirus strains.

Purpose of the Study:

• To review recent advancements in the evaluation of molecules as NPEV inhibitors.
• To summarize the structure-activity relationships (SAR) of these emerging antiviral compounds.
• To facilitate the development of novel, broad-spectrum antiviral drugs against Enteroviruses.

Main Methods:

• Literature review of recent studies on NPEV inhibitors.
• Analysis of structure-activity relationships for identified antiviral compounds.
• Compilation of data on direct antiviral agents and host-target inhibitors.

Main Results:

• Identification of several promising compounds evaluated for NPEV inhibition.
• Summary of SAR data, linking molecular structure to inhibitory activity.
• Overview of both direct antiviral agents and host-targeting strategies.

Conclusions:

• The review consolidates current knowledge on NPEV inhibitors and their SAR.
• This information is crucial for guiding the design of new, broad-spectrum Enterovirus antiviral drugs.
• Further research into these compounds could lead to urgently needed therapies.
