Cat.No. 4501 - Ribavirin | C8H12N4O5 | CAS No. 36791-04-5
Description: Antiviral guanosine analog; blocks eIF4E activity
Chemical Name: 1-β-D-Ribofuranosyl-1H-1,2,4-triazole-3-carboxamide
Purity: ≥99% (HPLC)

Biological Activity

Antiviral guanosine ribonucleoside analog; misincorporated into mRNA by viral-dependent RNA polymerases. Binds to and redistributes mammalian eIF4E from the nucleus to the cytoplasm (Ki ~ 0.3 μM for the active metabolite, ribavirin triphosphate). Represses colony formation of primary AML-M5 progenitor cells (IC50 ~ 1 μM); reduces disease severity in acute myeloid leukemia (AML). Orally available.

Compound Libraries

Ribavirin is also offered as part of the Tocriscreen Plus and Tocriscreen Library of FDA-Approved Compounds. Find out more about compound libraries available from Tocris.
