structure–activity studies on a diverse family of nucleoside phosphonic acids has led to the development of potent antiviral drugs such as HPMPC (CidofovirTM), PMEA (AdefovirTM), and PMPA (TenofovirTM), which are used in the treatment of CMV-induced retinitis, hepatitis B, and HIV, respectively. Here, we present the synthesis of a novel class of acyclic phosphonate nucleotides that have a locked conformation
对多种核苷膦酸家族的系统结构活性研究导致开发了有效的抗病毒药物,例如HPMPC(CidofovirTM),PMEA(AdefovirTM)和PMPA(TenofovirTM),这些药物用于治疗CMV诱导的视网膜炎,乙型肝炎和艾滋病毒。在这里,我们提出了一种新型的无环膦酸酯核苷酸的合成,其通过吡咯烷环具有锁定的构象。这些化合物的NMR分析表明,当吡咯烷环通过氢键成pD <10时为顺式时,其具有受约束的构象。测试了这些化合物中的四种作为人和恶性疟原虫的抑制剂6-氧嘌呤磷酸核糖基转移酶。最有效的恶性疟原虫HGXPRT的K i为0.6μM。
