Ara-AMP also has antiviral properties against some RNA viruses, such as HIV and influenza virus. Ara-AMP can be administered orally or by injection, making it suitable for use in children who are unable to take oral medication.</p>

<p>9-(β-D-xylofuranosyl)guanine (9XG) is a trifluoride. It is an antiviral agent that inhibits the growth of herpes virus, in particular by methylating guanosine to 9-methylguanosine in the viral DNA. 9XG binds to the viral DNA and prevents its replication through the inhibition of RNA synthesis. The drug is active against many different types of viruses and has been shown to be effective against tissue cultures infected with herpes virus. 9XG is synthesized from guanosine and boron trifluoride etherate, which are reacted at -78 degrees Celsius for three days. This yields a mixture of compounds with various peracylation groups, which are then separated by chromatography.</p>
