چکیده

The activities of amantadine and ribavirin against influenza A viruses were compared against low-multiplicity (plaque inhibition) and high-multiplicity (protein synthesis inhibition) infections. Our results suggest that the predictive value of in vitro data for the clinic may be improved by consideration of tests against a high-multiplicity infection.

Evaluation of the Embryonic Pathological Lesions and Efficacy of Amantadine against H9N2 Influenza Virus Using Chicken Embryo Model

Background & Aims: Various antiviral drugs such as amantadine are used to treat influenza. This drug is categorized in group C and few researches have been conducted about its toxic effects on human fetus. In the current study, the pathologic effects of the drug as well as drug efficacy in reducing influenza virus titer in the developing chicken embryo were assessed. <br ...

Efficacy of Combined Therapy with Amantadine, Oseltamivir, and Ribavirin In Vivo against Susceptible and Amantadine-Resistant Influenza A Viruses

The limited efficacy of existing antiviral therapies for influenza--coupled with widespread baseline antiviral resistance--highlights the urgent need for more effective therapy. We describe a triple combination antiviral drug (TCAD) regimen composed of amantadine, oseltamivir, and ribavirin that is highly efficacious at reducing mortality and weight loss in mouse models of influenza infection. ...

Triple Combination of Amantadine, Ribavirin, and Oseltamivir Is Highly Active and Synergistic against Drug Resistant Influenza Virus Strains In Vitro

The rapid emergence and subsequent spread of the novel 2009 Influenza A/H1N1 virus (2009 H1N1) has prompted the World Health Organization to declare the first pandemic of the 21st century, highlighting the threat of influenza to public health and healthcare systems. Widespread resistance to both classes of influenza antivirals (adamantanes and neuraminidase inhibitors) occurs in both pandemic a...

Pinanamine Is a Promising Lead Compound against Influenza A Virus: Evidence from in Vitro and in Vivo Efficacy Compared to Amantadine.

Influenza A viruses with the presence of mutations in M2 still circulate and threaten to avian species and human in China. A novel M2 inhibitor pinanamine was previously identified as an antiviral agent by an in vitro assay. In this study, we monitored the activity of pinanamine against influenza A/FM1/47 (H1N1) virus infection in cell culture and mice. Pinanamine showed more potent antiviral e...

Evaluation of carbodine, the carbocyclic analog of cytidine, and related carbocyclic analogs of pyrimidine nucleosides for antiviral activity against human influenza Type A viruses.

Carbodine, the carbocyclic analog of cytidine, was found to possess significant antiviral activity against influenza virus types A0/PR-8/34 and A2/Aichi/2/68 (Hong Kong) in vitro. The compound selectively inhibited PR-8 influenza virus-induced cytopathogenic effects in Madin-Darby canine kidney and inhibited Hong Kong influenza virus replication in primary rhesus monkey kidney cell cultures. Th...
