  Straightforward synthesis of bioconjugatable azo dyes. Part 1: Black Hole Quencher-1 (BHQ-1) scaffold

  摘要：

  Azo dyes are currently used to quench the fluorescence of energy donors in bioassays through Forster resonance energy transfer (FRET) phenomenon. Common examples of such dark quenchers are DABCYL and the three members of Black Hole Quencher (R) (BHQ) family. Yet, only carboxylic acid and phosphoramidite derivatives of such azo dyes are presently commercially available. This Letter presents a straightforward synthesis method to novel bioconjugatable quenchers derived from BHQ-1 scaffold and equipped with a reactive group being either azido, terminal alkyne, or maleimide. The potential utility of the 'clickable' azido and thiol-reactive derivatives was notably demonstrated through the preparation of the first water-soluble BHQ-1 dye and a FRET-based probe suitable for the detection of urokinase-type plasminogen activator (uPA), a key protease in cancer invasion and metastasis, respectively.

  可生物共轭的基于偶氮的深色猝灭染料：蛋白酶激活的远红荧光探针的合成与应用

  摘要：

  我们描述了基于黑洞Quencher-3（BHQ-3）支架的新型非荧光偶氮染料的高效合成和一步衍生。这些染料配备了各种反应性和/或生物结合性基团（叠氮基，α-碘乙酰基，酮，末端炔烃，邻二醇）。发现叠氮衍生物在铜催化的叠氮化物-炔烃环加成（CuAAC）反应中具有很高的反应活性，可以轻松合成第一批水溶性（磺化衍生物）和醛改性的BHQ-3染料，直接常规偶氮偶联反应无法制备。通过形成稳定的肟或硫醚键，可以轻松地将含醛和α-碘乙酰基的荧光猝灭剂与含氨氧基和半胱氨酸的肽偶联。

  Organozinc reagents are among the most commonly used organometallic reagents in modern synthetic chemistry, and multifunctionalized organozinc reagents can be synthesized from structurally simple, readily available ones by means of alkyne carbozincation. However, this method suffers from poor tolerance for terminal alkynes, and transformation of the newly introduced organic groups is difficult, which

  有机锌试剂是现代合成化学中最常用的有机金属试剂之一，多官能化的有机锌试剂可以通过炔烃碳酰化从结构简单、容易获得的有机锌试剂中合成。但该方法对末端炔烃的耐受性较差，且新引入的有机基团难以转化，限制了其应用。在此，我们报告了一种由新开发的带有 1,10-菲咯啉-亚胺配体的铁催化剂催化的末端炔烃的乙烯基锌化方法。该方法提供了从现成的乙烯基锌试剂和末端炔烃中有效获取具有多种结构和官能团的新型有机锌试剂的途径。该方法具有优异的官能团耐受性（可耐受的官能团包括氨基、酰胺、氰基、酯、羟基、磺酰基、缩醛、膦酰基、吡啶基），良好的底物范围（合适的末端炔烃包括具有各种官能团的芳基、烯基和烷基乙炔）组），以及高化学选择性、区域选择性和立体选择性。该方法可以显着提高包括维生素A在内的各种重要生物活性分子的合成效率。机理研究表明，本研究开发的新型铁-1,10-菲咯啉-亚胺催化剂具有极其拥挤的反应袋，促进了化合物的高

  The invention relates to fluorescent/fluorogenic probes of formula (I″) or (II″): wherein Z is chosen between: —NH 2 and —OH, or in the fluorescence quencher group consisting of: —NO 2 ; —N═N—R 1 ; R 1 being any organic group that does not obscure the corresponding azo bond; —NHCO-Pept.; Pept. being a peptide residue or any organic group that does not obscure the corresponding amide bond; —O-Glyc.; Glyc. being a oligoglycoside residue that does not obscure the corresponding glycosidic bond; —O—C(O)—R 2 ; —O—P(O)(OR 2 )(OR 2 ′) and —O—S(O) 2 —R 2 ; R 2 and R 2 ′ being independently a hydrogen atom or an organic group that does not obscure the corresponding ester bond; and R a , R b , R c , R d and R e being independently a hydrogen atom or any organic group that does not obscure the corresponding arylether bond so as not to prevent its possible cleavage by a myeloperoxidase activity. It also relates to the use of these fluorescent/fluorogenic probes, for the detection of an enzyme activity, notably in order to identify/discriminate microorganisms in function of their ability to express particular enzyme activities.

  Although carbozincation of terminal alkynes is a promising method for the synthesis of alkenylzinc reagents, many challenges, especially the chemo-, regio-, and stereoselectivity, remain to be addressed. Herein we report an operationally simple, mild method for iron-catalyzed alkylzincation of terminal alkynes to produce a diverse array of alkenylzinc compounds in high yields with high anti-Markovnikov

  尽管末端炔烃的羰基化是合成烯基锌试剂的一种很有前途的方法，但仍有许多挑战，特别是化学选择性、区域选择性和立体选择性有待解决。在这里，我们报告了一种操作简单、温和的方法，用于铁催化末端炔烃的烷基锌化，以高产率、高反马尔科夫尼科夫选择性和高顺式立体选择性产生多种烯基锌化合物。使用该方法，我们实现了末端炔烃的顺式烷基锌化，证明该方法具有广泛的底物范围（适用于芳基、烯基、烷基和杂原子取代的乙炔）和良好的官能团耐受性。因为 C(sp 2)─产物的锌键可以很容易地转化，该方法为传统的三取代烯烃选择性合成方法提供了具有竞争力的替代方案。本研究开发的铁催化剂在炔烃烷基化中表现出不可替代的反应性

  作者：Arnaud Chevalier、Pierre-Yves Renard、Anthony Romieu

  DOI：10.1021/ol501753b

  日期：2014.8.1

  A rapid access to a novel class of water-soluble dark quencher dyes was achieved using an azo-coupling reaction between a fluorescent primary arylamine derived from a sulforhodamine 101 scaffold and a tertiary aniline equipped with different bioconjugatable groups. The thus obtained nonfluorescent azo-sulforhodamine hybrids display a broad quenching range spanning the visible to NIR regions. This was demonstrated through the preparation and enzymatic activation of FRET-based fluorogenic substrates of urokinase.

  日期：2014.12

  A further extension of the efficient synthetic methodology described in Part I, to the aromatic bis-diazo scaffold of Black Hole Quencher-2 dye is presented. Bioconjugatable derivatives bearing either azido, terminal alkyne, or maleimide reactive group were easily obtained as well as the free-phenol form of BlackBerry (R) Quencher 650 (BBQ-650 (R)) initially developed by Berry & Associates, Inc. Company. The efficient conjugation ability of azido- and maleimide-quenchers was demonstrated through the facile preparation of the first water-soluble and formylated BHQ-2 dyes and a FRET-based probe suitable for the in vitro/in cellulo detection of a cancer-associated protease namely urokinase-type plasminogen activator.
