• Optimised Synthesis of the Bacterial Magic Spot (p)ppGpp Chemosensor PyDPA

  DOI：10.1002/cbic.201900013

  日期：2019.7

  Guanosine penta- or tetraphosphate (pppGpp or ppGpp, respectively) is a nucleotide signalling molecule with a marked effect on bacterial physiology during stress. Its accumulation slows down cell metabolism and replication, supposedly leading to the formation of the antibiotic-tolerant persister phenotype. A specifically tailored fluorescent chemosensor, PyDPA, allows the detection of (p)ppGpp in solution

  鸟苷五磷酸或四磷酸鸟嘌呤（分别为pppGpp或ppGpp）是一种核苷酸信号分子，在压力下对细菌生理学具有显着影响。它的积累减慢了细胞的代谢和复制，据推测导致了抗生素耐受性持久性表型的形成。专门定制的荧光化学传感器PyDPA可以相对于其他核苷酸，以高选择性检测溶液中的（p）ppGpp。本文中，提出了一种优化的合成方法，可通过7个步骤将总收率从9％提高到67％。这种方法的简单性和鲁棒性使研究小组可以轻松地研究（p）ppGpp的许多方面。
• Synthetic Routes to Fluorescent Dyes Exhibiting Large Stokes Shifts

  Derivatives of isomeric 2-(hydroxytolyl)-4,6-dimethylamino-1,3,5-triazines have been synthesized in high yields in a controlled manner using a multistep reaction sequence. Iodination of either 2-(1'-hydroxy-6'-methylphen-2'-yl)- or 2-(1'-hydroxy-4'-methylphen-2'-yl)-4,6-dimethylamino-1,3,5-triazine with ICl provides species differing in the positioning of the iodo group relative to the hydroxyl which readily undergo Suzuki, Sonogashira, and Heck reactions under Pd(0) catalysis. Thus, thienyl, bisthienyl, and 3,4-ethylenedioxythienyl groups have been directly grafted, while unsubstituted polycyclic aromatics such as pyrene and perylene have been linked via alkyne bridges, as have ethynyldifluoroborondipyrromethane (BODIPY) dyes prepared in situ. The presence of a hydrogen bond in the ground state involving the hydroxyl substituent has been established by proton NMR and several X-ray structure determinations. All of the new dyes with a simple substituent (phenyl, thienyl) exhibited a pronounced green fluorescence resulting from an intramolecular proton transfer:in:the excited state (ESIPT) which produces a large Stokes shift (> 10 000 cm(-1)). With other dyes, the fluorescence of the keto form responsible for the ESIPT process could be used as the.input energy in efficient intramolecular energy transfer processes. Replacing perylene with pyrene allowed reversal of the direction of energy transfer from the polyaromatic module to the keto form.

  Disclosed embodiments concern a probe comprising one or more pairs of monomers capable of targeting a nucleic acid target. The pair of monomers may be arranged in a manner that promotes thermoinstability of the probe complex, thus producing a probe capable of locating and/or detecting a target. The probe also may comprise one or more natural or non-natural nucleotides capable of Watson-Crick base pairing with an isosequential nucleic acid target. Particular disclosed embodiments concern a method of using the disclosed probe to target nucleic acids. In particular disclosed embodiments, the probe may be incubated with a target nucleic acid and then be detected.
