The combination of pleconaril, rupintrivir, and remdesivir efficiently inhibits enterovirus infections in vitro, delaying the development of drug-resistant virus variants
Antiviral Res. 2024 Feb 26:105842. doi: 10.1016/j.antiviral.2024.105842. Online ahead of print.ABSTRACTEnteroviruses are a significant global health concern, causing a spectrum of diseases from the common cold to more severe conditions like hand-foot-and-mouth disease, meningitis, myocarditis, pancreatitis, and poliomyelitis. Current treatment options for these infections are limited, underscoring the urgent need for effective therapeutic strategies. To find better treatment option we analyzed efficacy of 12 known broad-spectrum anti-enterovirals both individually and in combinations against different enteroviruses in vitr...

An in vivo duck hepatitis B virus model recapitulates key aspects of nucleic acid polymer treatment outcomes in chronic hepatitis B patients
In conclusion, subcutaneous administration of NAPs in the DHBV duck model provides a useful tool for in vivo evaluation of NAPs. It recapitulates many aspects of this class of compound's efficacy in CHB patients, most notably the clear division between responders and non-responders.PMID:38401714 | DOI:10.1016/j.antiviral.2024.105835 (Source: Antiviral Research)

Molnupiravir inhibits human norovirus and rotavirus replication in 3D human intestinal enteroids
Antiviral Res. 2024 Feb 17;223:105839. doi: 10.1016/j.antiviral.2024.105839. Online ahead of print.ABSTRACTHuman norovirus (HuNoV) and human rotavirus (HRV) are the leading causes of gastrointestinal diarrhea. There are no approved antivirals and rotavirus vaccines are insufficient to cease HRV associated mortality. Furthermore, treatment of chronically infected immunocompromised patients is limited to off-label compassionate use of repurposed antivirals with limited efficacy, highlighting the urgent need of potent and specific antivirals for HuNoV and HRV. Recently, a major breakthrough in the in vitro cultivation of HuNo...

Mechanism of action of phthalazinone derivatives against rabies virus

Online ahead of print.ABSTRACTRabies, a viral zoonosis, is responsible for almost 59,000 deaths each year, despite the existence of an effective post-exposure prophylaxis. Indeed, rabies causes acute encephalomyelitis, with a case-fatality rate of 100 % after the onset of neurological clinical signs. Therefore, the development of therapies to inhibit the rabies virus (RABV) is crucial. Here, we identified, from a 30,000 compound library screening, phthalazinone derivative compounds as potent inhibitors of RABV infection and more broadly of Lyssavirus ...

Neutralizing antibodies to block viral entry and for identification of entry inhibitors
Antiviral Res. 2024 Feb 16:105834. doi: 10.1016/j.antiviral.2024.105834. Online ahead of print.ABSTRACTNeutralizing antibodies (NAbs) are naturally produced by our immune system to combat viral infections. Clinically, neutralizing antibodies with potent efficacy and high specificity have been extensively used to prevent and treat a wide variety of viral infections, including Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), Human Immunodeficiency Virus (HIV), Dengue Virus (DENV) and Hepatitis B Virus (HBV). An overwhelmingly large subset of clinically effective NAbs operates by targeting viral envelope proteins...
