  Design, Synthesis, and Enzymatic Evaluation of Multisubstrate Analogue Inhibitors of Escherichia coli Thymidine Phosphorylase

  摘要：

  A series of acyclic phosphonate derivatives of thymine has been synthesized and tested as multisubstrate analogue inhibitors of Escherichia colt thymidine phosphorylase. The compounds synthesized include 1-(phosphonoalkyl)thymines with six to nine methylenes (1-4, respectively); 1-[(Z)-4-phosphonomethoxy-2-butenyl]thymine (5) and its butyl and 2,3-cis-dihydroxybutyl derivatives (6 and 7, respectively); 1-[(Z)-(4-(phosphonomethoxy)methoxy)-2-butenyl]thymine (8) and also its butyl and 2,3-cis-dihydroxybutyl analogues (9 and 10); and 1-[((Z)-4-(phosphonomethoxy)-2-butenoxy)methyl]thymine(11), Evaluation of these compounds against E. coli revealed significant enzymatic inhibition by 2, 3, 4, 6, and 8 at a concentration of 1000 mu M, 3 and 4 being the most potent. Replacement of the thymine base in 3 by 6-amino-5-bromouracil and 7-deazaxanthine afforded compounds 12 and 13, which showed a pronounced improvement of TPase inhibition, comparable to 7-deazaxanthine. When inorganic phosphate was used as a variable substrate, compounds 12 and 13 displayed competitive kinetics with respect to phosphate, indicating a direct interaction of these compounds with the phosphate binding site. Also compounds 12 and 13 were found to be competitive inhibitors of TPase against thymidine as a variable substrate. These results are consistent with the compounds being multisubstrate analogue inhibitors of E. coli TPase, and they represent the first example of such TPase inhibitors.

• Effect of a Polymethylene Chain on the Intramolecular Hydrogen Bond between Adenine and Thymine
  作者：Toshio Itahara

  DOI：10.1246/bcsj.75.285

  日期：2002.2

  The intramolecular hydrogen bond between the adenine and thymine rings of 9-[ω-(thymin-1-yl)alkyl]adenine was investigated in chloroform by means of NMR spectroscopy. The formation of the intramolecular hydrogen bond was dependent on the length of the polymethylene chains between adenine and thymine, and the thermodynamic parameters were estimated. The length of the polymethylene chains caused a marked difference in the physical properties of the compounds.

  在氯仿中，通过核磁共振谱法研究了9-[ω-(胸苷-1-基)烷基]腺苷的腺苷环和胸苷环之间的分子内氢键形成。分子内氢键的形成依赖于腺苷和胸苷之间聚亚甲基链的长度，并估算了热力学参数。聚亚甲基链的长度导致化合物的物理性质产生明显差异。
• NMR and UV Study of 1,1′-(<i>α</i>,<i>ω</i>-Alkanediyl)bis[thymine] and 1,1′-(<i>α</i>,<i>ω</i>-Alkanediyl)bis[uracil]

  日期：1997.9

  Treatment of thymine or uracil with Br(CH2)nBr (n = 3—10) in the presence of t-BuOK gave 1,1′-(α,ω-alkanediyl)bis[thymine] or 1,1′-(α,ω-alkanediyl)bis[uracil] together with 1-(ω-bromoalkyl)thymine or 1-(ω-bromoalkyl)uracil. The structures of these products were determined on the basis of the coupling constants between 5- and 3-positions of uracil ring on the 1H NMR spectra. Molecular aggregation of the thymine and uracil rings of these compounds in aqueous solution was studied on the basis of their 1H NMR and UV spectra. A stacking interaction of the two thymine rings linked by shorter polymethylene chains such as trimethylene and tetramenthylene groups was observed.

  将胸腺嘧啶或尿嘧啶与Br(CH2)nBr（n = 3—10）在t-BuOK存在下处理，得到了1,1′-(α,ω-烷烃二基)双[胸腺嘧啶]或1,1′-(α,ω-烷烃二基)双[尿嘧啶]，以及1-(ω-溴烷基)胸腺嘧啶或1-(ω-溴烷基)尿嘧啶。这些产物的结构是基于尿嘧啶环中5位和3位之间的耦合常数在1H NMR光谱上的分析来确定的。基于它们的1H NMR和紫外光谱，研究了这些化合物在水溶液中胸腺嘧啶和尿嘧啶环的分子聚集情况。观察到由较短的聚亚 methylene 链（如三亚甲基和四亚甲基基团）连接的两个胸腺嘧啶环之间存在堆叠相互作用。
