(ddhCTP) is a novel antiviral molecule produced by the enzyme viperin as part of the innate immune response. ddhCTP has been shown to act as an obligate chain terminator of flavivirus and SARS-CoV-2 RNA-dependent RNA polymerases; however, further biophysical studies have been precluded by limited access to this promising antiviral. Herein, we report a robust and scalable synthesis of ddhCTP as well as
3'-Deoxy-3',4'-didehydro-cytidine triphosphate (ddhCTP) 是一种新型抗病毒分子,由 viperin 酶产生,是先天免疫反应的一部分。ddhCTP 已被证明可作为黄病毒和 SARS-CoV-2 RNA 依赖性 RNA 聚合酶的专性链终止子;然而,由于获得这种有前途的抗病毒药物的机会有限,进一步的生物物理学研究被排除在外。在这里,我们分别报告了 ddhCTP 以及单磷酸盐和二磷酸盐 ddhCMP 和 ddhCDP 的稳健且可扩展的合成。2'-甲硅烷基醚保护策略的鉴定使 5'-三磷酸盐的选择性合成和简单纯化成为可能,最终以克级制备 ddhCTP。
