  3′-Oxo-, amino-, thio- and sulfone-acetic acid modified thymidines: Effect of increased acidity on ribonuclease A inhibition

  摘要：

  A family of 3'-functionalized thymidines carrying XCH2COOH (X = O, NH, S, SO2) groups has been designed as inhibitors of RNase A. This is because it is possible to manipulate the overall acidity of this new class of nucleic 'acids' by changing X from oxygen to the SO2 group in the series. It is also expected that the acyclic nature of the XCH2COOH group would provide enough flexibility to the -COOH group to have maximum interactions with the catalytic subsite P-1 of RNase A. As the -SO2CH2COOH substituted derivative showed better potency partially because of the increased acidity of the -COOH group, the inhibitory properties of both 5'-substituted and 3',5'-disubstituted sulfone acetic acid modified thymidines were investigated. Two -SO2CH2COOH groups were incorporated with the expectation of targeting two phosphate binding sites simultaneously. Thus, 3',5'-dideoxy-3',5'-bis-S-[(carboxymethyl)sulfonyl]thymidine emerged as the best inhibitor in this series with a K-i value of 25 +/- 2 mu M. (C) 2013 Elsevier Ltd. All rights reserved.

  摘要：

  描述了一种新的和方便的合成 3',5'-二硫胸苷的方法。在此过程中，DBU 用于形成 2,3'-脱水胸苷的分子内环，然后使用硫代乙酸作为溶剂和亲核试剂以生产 S-乙酰基-3'-硫代胸苷。应用非常有效的脱保护步骤来提供目标化合物，这可以避免硫醇基团的氧化。并且发现关键中间体 5'-O-tosyl-2,3'-脱水胸苷对不同的亲核试剂具有区域选择性。

  acid–dichloromethane (1:9 v/v) at 0 °C and then with zinc in hot acetic acid gives 3′,5′-dithiothymidine 5a and the cyclic disulfide 16, respectively, as crystalline solids in good overall yields. Although attempts to isolate the pure threo-dithio compoun 12b lead to the formation of the cyclic disulfide 16, when the crude material is treated with 2,2-dimethoxypropane in the presence of acid, its 3′,5′-S-isopropylidene

  This paper describes a convenient synthetic procedure for nucleoside mimics, 1-6, in which the 3',5'-hydroxy groups of natural 2'-deoxythymidine or 2'-deoxyadenosine are replaced by thiol, amine, or alkylthiol groups. Such nucleosides would be built up into a single DNA strand with cooperative participation of metal coordination, where internucleoside linkages are replaced by metal complexation motifs. The X-ray crystal structure and complexation behaviors of 3',5'-dithiothymidine, 1, with Au-I are also reported.
