Used primarily in the field of antiviral research, 2'-C-Methyladenosine serves as a nucleoside analog that inhibits the replication of RNA viruses. It is particularly effective against hepatitis C virus (HCV) by targeting the viral RNA polymerase, thereby preventing the synthesis of viral RNA. This compound is a key component in the development of antiviral drugs, contributing to the treatment of chronic hepatitis C infections. Its mechanism of action involves incorporation into the viral RNA chain, leading to chain termination and halting viral replication. Researchers also explore its potential in combating other RNA viruses, making it a valuable tool in the study of antiviral therapies.
