    1-(Adenin-9-yl)-1-deoxy-DL-ribitol (III), -D-arabitol (IXa), -L-arabitol (XIVa), -DL-xylitol (XXIVa), 1-(cytosin-L-yl)-1-deoxy-D-arabitol (IXb), -L-arabitol (XIVb), 1-(uracil-1-yl)-1-deoxy-D-arabitol (IXc), -L-arabitol (XIVc) and -DL-xylitol (XXIVb) were prepared by reaction of 1-O-p-toluenesulfonyl-2,3:4,5-di-O-isopropylidenealditols Ib, VIIb, XIIb and XXIIb with sodium salts of adenine, N4-benzoylcytosine or 4-methoxy-2-pyrimidone followed by removal of the protecting groups. Condensation of the mentioned sodium salts with methyl 5-O-p-toluenesulfonyl-2,3-O-isopropylidene-β-D-ribofuranoside (IV) with subsequent acid hydrolysis and reduction with sodium borohydride afforded 1-(adenin-9-yl)-1-deoxy-L-ribitol (VIa) and 1-(cytosin-1-yl)-1-deoxy-L-ribitol (VIb). 1-(Adenin-9-yl)-1-deoxy-L-lyxitol (XVII), -L-lyxitol (XVIII) and -2-O-methyl-D-lyxitol (XXI) were prepared analogously. Acid hydrolysis of 5-(adenin-9-yl)-5-deoxy-4-O-benzyl-1,2-O-isopropylidene-α-D-xylofuranose (XXVa), followed by reduction with sodium borohydride and catalytic hydrogenation, gave 1-(adenin-9-yl)-1-deoxy-L-xylitol (XXVIb).

    by the results of the modeling and NMR studies, and inspired by the success of acyclic antiviral nucleosides, compounds where a 5‐alkynyl uracyl moiety is coupled to an acyclic nucleoside phosphonate (ANP) were synthesized and evaluated. Of the compounds evaluated, sodium (6‐(5‐(3‐octanamidoprop‐1‐yn‐1‐yl)‐2,4‐dioxo‐3,4‐dihydropyrimidin‐1(2H)‐yl)hexyl)phosphonate (3 e) exhibited 43 % of inhibitory effect
    对新抗生素的迫切需求对靶向未开发的重要细胞过程提出了挑战。胸苷酸的生物合成就是这样一种过程,因为它在DNA复制和修复中起着至关重要的作用。胸苷酸合酶(TS)催化生物合成5-三磷酸胸苷(TTP)的关键步骤,这是DNA合成和修复所需的基本组成部分。迄今为止,由于TS抑制剂对人体酶和微生物酶的特异性不足,因此仅被成功用于抗癌治疗。但是,在一系列致病细菌中发现了一个新的TS酶家族(ThyX),该家族在结构和生化上与“经典” TS(ThyA)不同,这为开发选择性ThyX抑制剂作为有效的抗菌药物提供了可能。这里,1)用结核分枝杆菌从公开的晶体结构开始,使用分子模型探索ThyX酶,并通过NMR实验进一步证实。虽然化合物1的脱氧尿酸(dUMP)部分占据了ThyX中天然底物的腔,但其余的配体(“ 5-炔基尾巴”)延伸至酶的四个亚基中的两个之间。通过置换Tyr 44.C,Tyr 108.A和Lys 165.A
  • Reactions of Benzonitrile Oxide with Methoxypyrimidines and Pyrimidones

    Methoxypyrimidines preferentially add to benzonitrile oxide to give cycloadducts to their C=N double bonds. These, however, lose benzonitrile affording the corresponding pyrimidones. Cycloadditions to their C=C double bonds take place to a very low extent, and products generally undergo a ring opening process which affords the corresponding oximes. Pyrimidones preferentially give addition products
    甲氧基嘧啶优先添加到氧化苯甲腈上,从而在其 C=N 双键上形成环加合物。然而,这些失去苄腈,得到相应的嘧啶酮。它们的 C=C 双键的环加成作用非常低,产物通常会经历开环过程,从而提供相应的肟。嘧啶酮优先为其氮原子提供加成产物,并且仅在 4-嘧啶酮的情况下,其 C=C 双键的环加合物才被分离出来。
  • Synthesis and biological evaluation of acyclic nucleotide analogues with a furo[2,3-<i>d</i>]pyrimidin-2(3<i>H</i>)-one base

    As a part of a broader structure–activity relationship (SAR) study of bicyclic nucleoside analogues (BCNAs) [anti-varicella-zoster virus (anti-VZV) and anti-human cytomegalovirus (anti-HCMV) agents], a novel series of 2-(phosphonomethoxy)ethyl (PME) substituted furo[2,3-d]pyrimidin-2(3H)-ones was synthesized. The target acyclic nucleotide analogues were prepared by Sonogashira coupling of protected 5-iodo-1-[2-(phosphonomethoxy)ethyl]uracil with various 1-alkynes, followed by in situ Cu(I)-promoted intramolecular cyclization and standard removal of the isopropyl ester groups. None of the prepared PME analogues were active at subtoxic concentrations against VZV thymidine kinase competent (TK+), VZV thymidine kinase deficient (TK), HCMV, or any other viruses tested.

    作为对双环核苷类似物(BCNAs)[抗水痘-带状疱疹病毒(anti-VZV)和抗人类巨细胞病毒(anti-HCMV)药物]进行更广泛的结构-活性关系(SAR)研究的一部分,合成了一系列新型 2-(膦甲氧基)乙基(PME)取代的呋喃并[2,3-d]嘧啶-2(3H)-酮。目标无环核苷酸类似物是通过受保护的 5-碘-1-[2-(磷酰甲氧基)乙基]尿嘧啶与各种 1-炔烃的 Sonogashira 偶联,然后在原位 Cu(I)促进下进行分子内环化,并以标准方式去除异丙酯基团而制备的。所制备的 PME 类似物在亚毒性浓度下对 VZV 胸苷激酶能力(TK+)、VZV 胸苷激酶缺陷(TK-)、HCMV 或任何其他受测病毒均无活性。

    Reaction of (R)-1-O-p-toluenesulfonyl-1,2,3-propanetriol (IV) with N-trimethylacetylimidazole (II) afforded (R)-1-O-p-toluenesulfonyl-3-O-trimethyacetyl-1,2,3-propanetriol (V) which was reacted with dimethoxymethane in the presence of phosphorus pentoxide to give (R)-2-O-methoxymethyl-1-O-p-toluenesulfonyl-3-O-trimethyacetyl-1,2,3-propanetriol (VI). Compound VI was treated with acetic anhydride and boron trifluoride etherate and the obtained 2-acetoxy derivative VII reacted with bromotrimethylsilane to give the intermediary bromomethyl ether VIII. Compound VIII on reaction with tris(2-propyl) phosphite afforded (R)-2-O-bis(2-propyl)phosphonomethyl-1-O-p-toluenesulfonyl-3-O-trimethyacetyl-1,2,3-propanetriol (IX). Condensation of synthon IX with sodium salts of adenine, 2,6-diaminopurine, or with cytosine, 6-azacytosine or 2-chloroadenine in the presence of cesium carbonate, afforded fully protected diesters X and XIIIb which on methanolysis and reaction with bromotrimethylsilane gave N-[(S)-(3-hydroxy-2-phosphonomethoxypropyl)] derivatives of adenine (XIa), 2- chloroadenine (XIb), 2,6-diaminopurine (XIc), cytosine (XIVa) and 6-azacytosine (XIVb). In an analogous reaction, sodium salt of 4-methoxy-2-pyrimidone reacted with compound IX to give an intermediate XIIIa which on treatment with methanolic ammonia and subsequent deblocking under the same conditions also afforded the cytosine derivative XIVa. Sodium salt of 2-amino-6-chloropurine was in this way converted into the corresponding 2-aminopurine derivative XVIII. Deprotection of this compound gave 9-(S)-(3-hydroxy-2-phosphonomethoxypropyl)-2-aminopurine (XIX).
