9-(b-D-Arabinofuranosyl)adenine

9-(b-D-Arabinofuranosyl)adenine is a nucleoside that is used as an antiviral agent. It binds to viral RNA and inhibits viral replication. 9-(b-D-Arabinofuranosyl)adenine has been shown to have potent side-effect profiles, including myocardial infarct, neuronal death, and immunological reactions. These effects are due to its ability to inhibit the synthesis of guanine nucleotides in the heart and brain cells, which are essential for energy production and neurotransmitter release respectively. 9-(b-D-Arabinofuranosyl)adenine also binds to toll-like receptors (TLRs), which are proteins found on the surface of cells that recognize invading microbes or foreign substances. This binding leads to activation of immune response pathways.
