ddhCTP
ddhCTP is a biologically occurring nucleotide analog generated by the interferon-induced enzyme Viperin. Viperin catalyzes an S-adenosyl-l-methionine (SAM)-dependent radical-mediated reaction converting cytidine triphosphate (CTP) into 3'-deoxy-3',4'-didehydro-CTP (ddhCTP). ddhCTP acts as a chain terminator targeting RNA-dependent RNA polymerases of flaviviruses, interrupting viral RNA synthesis. This molecule inhibits replication of viruses such as dengue, West Nile, and Zika viruses, demonstrating antiviral potential in mammalian cellular contexts and in vivo models, thus representing an important research tool in antiviral studies.
