Article Synopsis
- Development of broad-spectrum antiviral therapies, like 4'-fluorouridine (4'-FlU), is crucial for effectively responding to outbreaks and pandemics caused by emerging viruses, particularly those that cause hemorrhagic fevers, which have seen increasing morbidity and mortality rates.
- 4'-FlU has shown antiviral activity against several hemorrhagic fever viruses in cell cultures and has demonstrated high efficacy in guinea pig models infected with lethal arenaviruses, maintaining its effectiveness at low doses.
- When administered late in infection, 4'-FlU not only resolved clinical symptoms quickly but also showcased its potential as a therapeutic option with a broader application against various viral pathogens.
Nipah virus (NiV) causes near-annual outbreaks of fatal encephalitis and respiratory disease in South Asia with a high mortality rate (∼70%). Since there are no approved therapeutics for NiV disease in humans, the WHO has designated NiV and henipaviral diseases priority pathogens for research and development. We generated a new recombinant green fluorescent reporter NiV of the circulating Bangladesh genotype (rNiV-B-ZsG) and optimized it alongside our previously generated Malaysian genotype reporter counterpart (rNiV-M-ZsG) for antiviral screening in primary-like human respiratory cell types.

- There are currently no vaccines or treatments approved for Lassa virus (LASV) infections.
- Researchers conducted a screening of nearly 60,000 compounds to find anti-LASV activity under high biosafety conditions.
- The most promising compound found was Mac128, which effectively inhibited LASV replication and significantly reduced viral levels by targeting the polymerase enzyme.
Ebola disease outbreaks are major public health events because of human-to-human transmission and high mortality. These outbreaks are most often caused by Ebola virus, but at least three related viruses can also cause the disease. In 2022, Sudan virus re-emerged causing more than 160 confirmed and probable cases.
View Article and Find Full Text PDFArenaviruses are highly pathogenic viruses that pose a serious public health threat. Chapare virus (CHAV) and Machupo virus (MACV), two New World arenaviruses, cause hemorrhagic fevers with case fatality rates of up to 45%. Research on therapeutic drug targets and vaccines for these viruses is limited because biosafety level 4 containment is required for handling them.
