  摘要：

  一系列5-烷基-2'-脱氧尿苷3'，5'-环一磷酸酯（5-R-cdUMP's，R = Et，i-Pr，n-Pr，n-Bu，n-Pent，n-Hex，与5-烷基2'-脱氧尿苷（5-R-dUrd's本身）相比，制备并在培养系统中测试了n-Oct）作为抗肿瘤和抗病毒剂。仅5-Et-和5-n-Bu-cdUMP对鼠L1210和人淋巴母细胞Raji细胞表现出明显的细胞抑制活性（ID50范围：28-82微克/ mL）。5-Et-dUrd本身更具活性（ID50 = 1.6和2.9微克/ mL）。5-i-Pr-和5-n-Bu-dUrd处于非活性状态，但对于链长为五个碳或以上的基团，活性再次提高。5-Et-cdUMP和5-Et-dUrd对脱氧胸苷激酶缺陷型（TK-）L1210和Raji细胞的活性大大降低。在涉及TK细胞的情况下，5-Et-cdUMP显然不是相应5'-单磷酸的有效前药来源。在5-R-cdUMP中

  We present the unprecedented hyperpolarization of the cancer-targeting aptamer AS1411 via parahydrogen. For that, we screened for suitable parahydrogen-induced polarization (PHIP) labels, performed solid phase synthesis to incorporate the label into AS1411 and adapted the polarity of DNA via PEGylation to enable efficient, selective hydrogenation in organic solvents without affecting canonical nucleotides

  我们通过对氢展示了癌症靶向适体 AS1411 前所未有的超极化。为此，我们筛选了合适的对位氢诱导极化 (PHIP) 标记，进行固相合成以将标记整合到 AS1411 中，并通过聚乙二醇化调整 DNA 的极性，以在不影响规范核苷酸的情况下在有机溶剂中实现高效、选择性氢化。
• Zwitterionic DNA

  As a strategy to make DNA net charge neutral, oligodeoxynucleotides bearing pyrimidine 5-omega-aminohexyl substituents have been synthesized and characterized. The resultant zwitterionic oligomers bind to natural DNA at low ionic strength as well or better than does natural DNA with itself, even when all of the nucleotides in a given single. strand are rendered zwitterionic. As would be expected, stabilities of duplexes bearing zwitterionic strands are relatively insensitive to changes in solution ionic strength as compared with natural DNA. Somewhat surprising, however, is the finding that a DNA duplex composed of a fully zwitterionic strand and a natural complementary strand exhibits no change in stability over a 20-fold change in ionic strength. Thus, double- and single-stranded states in this case have equivalent charge densities, consistent with the zwitterionic strand contributing no net charge. Stabilization due to the ammonium ions was verified by comparing free energies of DNA duplexes bearing hexyl tethered ammonium ions with those bearing simply hexyl groups devoid of ammonium ions. This comparison showed that without an added positive ammonium ion, the hexyl tether itself has a severe and cumulative unfavorable effect on duplex stability. Finally, zwitterionic nucleotides are found to distinguish matched from mismatched nucleotides in complementary DNA strands to a degree that rivals natural DNA.

  A series of 5-alkyl-2'-deoxyuridine 3',5'-cyclic monophosphates (5-R-cdUMP's, R = Et, i-Pr, n-Pr, n-Bu, n-Pent, n-Hex, n-Oct) was prepared and tested in culture systems as antitumor and antiviral agents in comparison to the 5-alkyl-2'-deoxyuridines (5-R-dUrd's) themselves. Only the 5-Et- and 5-n-Bu-cdUMP showed appreciable cytostatic activities against murine L1210 and human lymphoblast Raji cells
