Popis: The naturally occurring nucleotide, 3’-deoxy-3’,4’-didehydro-cytidine-5’-triphosphate (ddhCTP), was recently found to exert potent and broad-spectrum antiviral activity. However, nucleoside 5’-triphosphates in general are not cell permeable, which precludes the direct use of ddhCTP as a therapeutic. To harness the therapeutic potential of this endogenous antiviral nucleotide, we synthesized phosphoramidate prodrug HLB-0532247 (1), and found it to result in dramatically elevated levels of ddhCTP in cells. We compared 1 and 3’-deoxy-3’,4’-didehydro-cytidine (ddhC) and found that 1 more effectively reduces titers of Zika and West Nile viruses in cell culture with minimal non-specific toxicity to host cells. We conclude that 1 is a promising antiviral agent based on a novel strategy of facilitating elevated levels of the endogenous ddhCTP antiviral nucleotide.
