© Ivyspring International Publisher. Background: Bioluminescence imaging (BLI) is one of the most widely used optical platforms in molecular imaging, but it suffers from severe tissue attenuation and autoluminescence in vivo. Methods: Here, we developed a novel BLI platform on the basis of bioluminescence resonance energy transfer (BRET) for achieving a ∼300 nm blue-to-near infrared shift of the emission (NIR-BRET) by synthesizing an array of 18 novel coelenterazine (CTZ) derivatives, named “Bottle Blue (BBlue)” and a unique iRFP-linked RLuc8.6-535SG fusion protein as a probe. Results: The best NIR-BRET was achieved by tuning the emission peaks of the CTZ derivatives to a Soret band of the iRFP. In mammalian cells, BBlue2.3, one of the CTZ derivatives, emits light that is ∼50-fold brighter than DBlueC when combined with RLuc8.6-535SG, which shows stable BL kinetics. When we used a caged version of BBLue2.3, it showed a BL half decay time of over 60 minutes while maintaining the higher signal sensitivity. This NIR BL is sufficiently brighter to be used for imaging live mammalian cells at single cell level, and also for imaging metastases in deep tissues in live mice without generating considerable autoluminescence. A single-chain probe developed based on this BLI platform allowed us to sensitively image ligand antagonist-specific activation of estrogen receptor in the NIR region. Conclusion: This unique optical platform provides the brightest NIR BLI template that can be used for imaging a diverse group of cellular events in living subjects including protein‒protein interactions and cancer metastasis.

Electrochemical Pinacol Coupling of Acetophenone Using Boron-Doped Diamond Electrode

　View Summary

© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim An electrochemical pinacol coupling reaction of acetophenone using a boron-doped diamond (BDD) electrode has been reported. This transformation is driven by the one-electron reduction of acetophenone on the BDD cathode, followed by an intermolecular radical coupling. Owing to the BDD's outstanding electrochemical properties, the pinacol-type compound has been obtained in good conversion yield. The roles of a supporting electrolyte and solvent were addressed; (1) lithium ions contribute to increase in the reactivity of the radical intermediate. (2) Addition of water promotes the electron transfer process at the BDD surface. The reaction is relatively tolerant to para-substituted acetophenone derivatives. Since electric current is directly employed as reducing reagents to generate a radical intermediate, the reaction is metal-free, sustainable, and inherently safe.

　View Summary

© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim A coelenterazine (CTZ) analogue emitting near-infrared (NIR) bioluminescence was synthesized for through-bond energy transfer (TBET)-based imaging modalities. The analogue, named Cy5-CTZ, was prepared by conjugating cyanine-5 (Cy5) dye to CTZ through an acetylene linker. This novel derivative is intrinsically fluorescent and emits NIR-shifted luminescence upon reacting with an appropriate luciferase, the Renilla luciferase. This Cy5-CTZ substrate is optically stable in physiological samples and rapidly permeabilize through the plasma membrane into the cytosolic compartment of live cells.

Oxidative Cleavage of the Acyl-Carbon Bond in Phenylacetone with Electrogenerated Superoxide Anions

　View Summary

© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim An oxidative cleavage reaction of the acyl−carbon bond in phenylacetone derivatives under cathodic reduction is reported. This particular transformation is driven by the cathodic reduction of dissolved molecular oxygen to superoxide anions. Various cathode materials were examined, and we discovered that boron-doped diamond (BDD) enables highly efficient molecular conversion, owing to BDD's outstanding electrochemical property for utilizing the small amounts of molecular oxygen effectively. The scope of the reaction is broad and can be applied to a variety of substrates, ranging from ketones to esters and amides. As an electric current is directly employed to generate the superoxide anion, the reaction is metal- and catalyst-free. Electro-organic synthesis using the carbon-based BDD electrode thus provides access to sustainable molecular transformations.

© 2018 American Chemical Society. Native coelenterazine (nCTZ) is a common substrate to most marine luciferases and photoproteins. In this study, nine novel dye- and azide-conjugated CTZ analogues were synthesized by conjugating a series of fluorescent dyes or an azide group to the C-2 or C-6 position of the nCTZ backbone to obtain bulkiness-driven substrate specificity and potential chemiluminescence/bioluminescence resonance energy transfer (C/BRET). The investigation on the optical properties revealed that azide-conjugated CTZs emit greatly biased bioluminescence to ALucs and ca. 130 nm blue-shifted bioluminescence with RLuc8.6 in living animal cells or lysates. The corresponding kinetic study explains that azide-conjugated CTZ exerts higher catalytic efficiency than nCTZ. Nile red-conjugated CTZ completely showed red-shifted CRET spectra and characteristic BRET spectra with artificial luciferase 16 (ALuc16). No or less spectral overlap occurs among [Furimazine-NanoLuc], [6-N 3 -CTZ-ALuc26], [6-pi-OH-CTZ-RLuc8.6], and [6-N 3 -CTZ-RLuc8.6] pairs, because of the substrate-driven luciferase specificity and color shifts, providing a crosstalk-free multiplex bioassay platform. The unique bioluminescence system appends a new toolbox to bioassays and multiplex molecular imaging platforms. This study is the first example that systematically synthesized fluorescent dye-conjugated CTZs and applied them for a bioluminescence assay system.
