Ribavirin is a nucleoside drug used to treat RNA viral infections such as Hepaptitis C, which interferes with RNA metabolism required for viral replication. But its efficiency is relatively low, so in a HOT article just published, Yang He and colleagues at Sichuan University report the synthesis of two new nucleosides and their improved anti-viral activity.
He’s nucelosides contain structural features of two naturally occurring components of RNA (guanine and cytosine). This unique feature allows it to interfere with the RNA virus via hydrogen bond pairing with either guanine or cytosine, as well as allowing it to be recognised by viral enzymes more efficiently than ribavirin.
