Abstract
Enterovirus D68 (EV-D68) has had several outbreaks worldwide, yet no FDA-approved antiviral is available for treating this viral infection. EV-D68 infection typically leads to respiratory illnesses and, in severe cases, can cause neurological complications and even death, particularly in children. This study identified a small molecule, A-967079, as an EV-D68 antiviral through phenotypical screening. A-967079 has shown potent and broad-spectrum antiviral activity with a high selectivity index against multiple strains of EV-D68. Pharmacological characterization of the mechanism of action involving time-of-addition, resistance selection, and differential scanning fluorimetry assays suggests that viral 2C protein is the drug target. Overall, A-967079 represents a promising candidate for further development as an EV-D68 antiviral.
期刊介绍：
ACS Infectious Diseases will be the first journal to highlight chemistry and its role in this multidisciplinary and collaborative research area. The journal will cover a diverse array of topics including, but not limited to:
* Discovery and development of new antimicrobial agents — identified through target- or phenotypic-based approaches as well as compounds that induce synergy with antimicrobials.
* Characterization and validation of drug target or pathways — use of single target and genome-wide knockdown and knockouts, biochemical studies, structural biology, new technologies to facilitate characterization and prioritization of potential drug targets.
* Mechanism of drug resistance — fundamental research that advances our understanding of resistance; strategies to prevent resistance.
* Mechanisms of action — use of genetic, metabolomic, and activity- and affinity-based protein profiling to elucidate the mechanism of action of clinical and experimental antimicrobial agents.
* Host-pathogen interactions — tools for studying host-pathogen interactions, cellular biochemistry of hosts and pathogens, and molecular interactions of pathogens with host microbiota.
* Small molecule vaccine adjuvants for infectious disease.
* Viral and bacterial biochemistry and molecular biology.
