Influenza viruses of types A and B cause periodic pandemics in the human population. The antiviral drugs approved to combat influenza virus infections are currently limited. We have investigated a novel effective inhibitor of human influenza A and B virus triazavirine (2-methylthio-6-nitro-1,2,4-triazolo[5,1-C]-1,2,4-triazine-7(4H)-one, TZV). TZV suppressed replication of influenza virus in cell culture, chicken chorioallantoic membranes, protected mice from death caused by type A and B influenza viruses. TZV was also effective against rimantadine-resistant influenza strain and avian influenza A virus strain H5N1. Pharmacokinetic parameters and bioavailability of TZV were calculated after TZV administration in rabbits. The TZV metabolite (2-methylthio-6-amino-1,2,4-triazolo[5,1-s]-1,2,4-triazin(e)-7(4H)-one, AMTZV) was discovered in cell cultures HEK 293T and Huh7, liver homogenate, and in rabbit blood after TZV intragastric administration. The AMTZV was non-toxic and inactive as influenza inhibitor in cell culture. Most likely metabolite is a product of TZV elimination.
