  Fluorescence Quenchers for Hydrazone and Oxime Orthogonal Bioconjugation

  摘要：

  We describe the synthesis and properties of new fluorescence quenchers containing aldehyde, hydrazine, and aminooxy groups, allowing convenient bioconjugation as oximes or hydrazones. Conjugation to oligonucleotides proceeded in high yield with aniline as catalyst. Kinetics studies of conjugation show that, under optimal conditions, a hydrazine or aminooxy quencher can react with aldehyde-modified DNA to form a stable hydrazone or oxime adduct in as little as five minutes. The resulting quencher-containing DNAs were assessed for their ability to quench the emission of fluorescein in labeled complements and compared to the commercially available dabcyl and Black Hole Quencher 2 (BHQ2), which were conjugated as phosphoramidites. Results show that the new quenchers possess slightly different absorbance properties compared to dabcyl and are as efficient as the commercial quenchers in quenching fluorescein emission. Hydrazone-based quenchers were further successfully incorporated into molecular beacons and shown to give high signal to background ratios in single nucleotide polymorphism detection in vitro. Finally, aminooxy and hydrazine quenchers were applied to quenching of an aldehyde-containing fluorophore associated with living cells, demonstrating cellular quenching within one hour.

  CuCl和DMAP催化2-苯基苯肼羧酸烷基酯的好氧氧化

  摘要：

  近来，由于2-苯基偶氮羧酸烷基酯，报道了各种富有成效的有机反应，例如催化的Mitsunobu反应，但是，2-苯基偶氮羧酸烷基酯的合成很大程度上取决于有毒氧化剂的化学计量使用。在该手稿中，公开了一种环境友好的2-苯基肼甲酸烷基酯的好氧氧化转化为2-苯基偶氮羧酸烷基酯的方法。在温和条件下，使用CuCl和DMAP系统可有效催化2-苯基肼甲酸烷基酯的需氧氧化。本发明的铜催化反应速率比以前报道的铁催化速率快得多，并且在3小时内合成了多种偶氮产物。本协议在更大范围内是有效的。

  A new copper salt catalyzed C-N coupling is described. This smooth reaction between azo compounds and organobismuth reagents provides efficient and highly regioselective access to Boc-protected aryl hydrazines. The yields under optimized conditions are mostly excellent and the synthetic procedure is robust and simple.
