  Synthesis of pyridinone ribonucleoside 3′-O-phosphoramidites and their incorporation into oligoribonucleotides

  摘要：

  Protected pyridin-2- and pyridin-4-one ribonucleosides 3 and 9 were synthesized using a one-pot reaction of silylated bases with 1-O-acetyl-tri-O-benzoyl-beta-D-ribofuranose (2) in the presence of CF(3)SO(3)SiMe(3) The nucleosides were converted in 4 steps into 3'-O-phosphoramidites 7 and 11 which were incorporated into hammerhead ribozyme substrates using solid-phase phosphoramidite chemistry.

  Cytidine-5‘-triphosphate synthase (CTPS) catalyzes the formation of cytidine triphosphate (CTP) from glutamine, uridine 5‘-triphosphate (UTP), and adenosine 5‘-triphosphate (ATP). This reaction proceeds via formation of the high-energy intermediate UTP-4-phosphate (UTP-4-P). Stable analogues of UTP-4-P may be potent inhibitors of CTPS and useful as lead structures for the development of anticancer

  胞嘧啶5'-三磷酸合酶（CTPS）催化由谷氨酰胺，尿苷5'-三磷酸（UTP）和腺苷5'-三磷酸（ATP）形成胞苷三磷酸（CTP）。该反应通过形成高能中间体UTP-4-磷酸盐（UTP-4-P）进行。UTP-4-P的稳定类似物可能是CTPS的有效抑制剂，可用作开发抗癌和抗病毒剂的先导结构。已经制备了尿苷4-磷酸酯（U-4-P）类似物的几个双亚甲基三磷酸酯（BMT）核苷酸。关键步骤是借助锡催化剂对2'，3'，5'-三-O-乙酰基或三-O的5'酯部分进行选择性甲醇分解-苯甲酰基U-4-P类似物。我们认为，这代表了在苯甲酰化核苷中选择性裂解5'苯甲酸酯的第一个通用方法。将这些5'-脱保护的U-4-P类似物与未对称的，受保护的BMT在末端位置之一上带有游离膦酸部分的Mitsunobu偶联，得到了完全保护的BMT-U-4-P类似物。使用TMSBr，然后用NH 4 OH-MeOH或NH 4 OH-吡啶处理
