Ribavirin: Hepatitis C [15] nucleoside analogue reverse transcriptase inhibitor: Rilpivirine (Edurant) [16] HIV Rimantadine: Influenza A: M2 proton channel antagonist Ritonavir: HIV HIV-1 protease inhibitor Saquinavir: HIV Simeprevir (Olysio) Hepatitis C Sofosbuvir: Hepatitis C [17] nucleoside analogue reverse transcriptase inhibitor: Stavudine ...
Ribavirin's amide group can make the native nucleoside drug resemble adenosine or guanosine, depending on its rotation. For this reason, when ribavirin is incorporated into RNA, as a base analog of either adenine or guanine, it pairs equally well with either uracil or cytosine , inducing mutations in RNA-dependent replication in RNA viruses.

It is expected eventually to be the drug of choice for viral hepatitis syndromes in which ribavirin is active. These include hepatitis C and perhaps also hepatitis B and yellow fever.
An interesting variation of this idea is the use of genetically modified cells that can produce custom-tailored ribozymes. This is part of a broader effort to create genetically modified cells that can be injected into a host to attack pathogens by generating specialized proteins that block viral replication at various phases of the viral life ...
