2'-β-C-Ethynyladenosine

2'-β-C-Ethynyladenosine is a synthetic nucleoside analog that potently inhibits HCV replication by targeting the viral NS5B polymerase, with IC50 values in the sub-micromolar range. It also exhibits significant activity against Leishmania RNA Virus 1 (LRV1), making it a valuable tool for antiviral research in both in vitro replicon systems and studies of parasitic viral co-infections.
