  荧光对取代苯基-咪唑并胞苷类似物

  摘要：

  此处描述了修饰的胞苷类似物的合成和光谱性质。为了赋予荧光特性，胞苷荧光团在胞嘧啶5位上通过肉桂基部分扩展（类似物1a – c），或在苯基咪唑环上扩展（类似物3a – d）。这些化合物分别通过Suzuki-Miyaura偶联反应和5-氨基胞苷与对位取代的苯甲醛的缩合反应合成。所有的类似物在蓝色区域为荧光（λ EM：402-436纳米）。在上述类似物中，对-CF 3-苯基-咪唑并胞苷3d被发现是一种很有前途的荧光探针，其量子产率比胞苷大7000倍（Φ = 0.617），并且红移约为。最大发射108 nm（411 nm）。其保留的Watson-Crick氢键键合面使3d可以与鸟苷特异性碱基配对，类似于胞苷。另外，苯基-咪唑并胞苷类似物优选反构象和C 3'-内切（N）糖折叠。这些特性使3d成为吸引人的荧光探针，可潜在地用于核酸化学的各个方面。

• Phenyl-imidazolo-cytidine Analogues: Structure–Photophysical Activity Relationship and Ability To Detect Single DNA Mismatch

  To expand the arsenal of fluorescent cytidine analogues for the detection of genetic material, we synthesized para-substituted phenyl-imidazolo-cytidine ((Ph)ImC) analogues 5a-g and established a relationship between their structure and fluorescence properties. These analogues were more emissive than cytidine (λem 398-420 nm, Φ 0.009-0.687), and excellent correlation was found between Φ of 5a-g and σp(-) of the substituent on the phenyl-imidazolo moiety (R(2) = 0.94). Calculations suggested that the dominant tautomer of (Ph)ImC in methanol solution is identical to that of cytidine. DFT calculations of the stable tautomer of selected (Ph)ImC analogues suggested a relationship between the HOMO-LUMO gap and Φ and explained the loss of fluorescence in the nitro analogue. Incorporation of the CF3-(Ph)ImdC analogue into a DNA probe resulted in 6-fold fluorescence quenching of the former. A 17-fold reduction of fluorescence was observed for the G-matched duplex vs ODN(CF3-(Ph)ImdC), while for A-mismatched duplex, only a 2-fold decrease was observed. Furthermore, since the quantum yield of ODN(CF3-(Ph)ImdC):ODN(G) was reduced 17-fold vs that of a single strand, whereas that of ODN(CF3-(Ph)ImdC):ORN(G) was reduced only 3.8-fold, ODN(CF3-(Ph)ImdC) appears to be a DNA-selective probe. We conclude that the ODN(CF3-(Ph)ImdC) probe, exhibiting emission sensitivity upon single nucleotide replacement, may be potentially useful for DNA single nucleotide polymorphism (SNP) typing.
