Spontaneously Blinking Fluorophores Based on Nucleophilic Addition/Dissociation of Intracellular Glutathione for Live-Cell Super-resolution Imaging

Single-molecule localization microscopy (SMLM) allows the reconstruction of super-resolution images but generally requires prior intense laser irradiation and in some cases additives to induce blinking of conventional fluorophores. We previously introduced a spontaneously blinking rhodamine fluorophore based on an intramolecular spirocyclization reaction for live-cell SMLM under physiological conditions. Here, we report a novel principle of spontaneous blinking in living cells, which utilizes reversible ground-state nucleophilic attack of intracellular glutathione (GSH) upon a xanthene fluorophore. Structural optimization afforded two pyronine fluorophores with different colors, both of which exhibit equilibrium (between the fluorescent dissociated form and the nonfluorescent GSH adduct form) and blinking kinetics that enable SMLM of microtubules or mitochondria in living cells. Furthermore, by using spontaneously blinking fluorophores working in the near-infrared (NIR) and green ranges, we succeeded in dual-color live-cell SMLM without the need for optimization of the imaging medium.

Cation-π interactions contribute to substrate recognition in γ-butyrobetaine hydroxylase catalysis

γ-Butyrobetaine hydroxylase (BBOX) is a non-heme FeII- and 2-oxoglutarate-dependent oxygenase that catalyzes the stereoselective hydroxylation of an unactivated C-H bond of γ-butyrobetaine (γBB) in the final step of carnitine biosynthesis. BBOX contains an aromatic cage for the recognition of the positively charged trimethylammonium group of the γBB substrate. Enzyme binding and kinetic analyses on substrate analogues with P and As substituting for N in the trimethylammonium group show that the analogues are good BBOX substrates, which follow the efficiency trend N+>P+>As+. The results reveal that an uncharged carbon analogue of γBB is not a BBOX substrate, thus highlighting the importance of the energetically favorable cation-π interactions in productive substrate recognition. What's in the BBOX? Enzyme kinetics and substrate binding studies reveal that γ-butyrobetaine hydroxylase (BBOX)-catalyzed stereoselective hydroxylation of γ-butyrobetaine involves energetically favorable cation-π interactions.

Synthesis and evaluation of phenoxymethylbenzamide analogues as anti-trypanosomal agents

The synthesis and anti-trypanosomal activity of a compound library based on a phenoxymethylbenzamide hit discovered in a high throughput screen is described. Several of the analogues exhibited potent activity against Trypanosoma brucei rhodesiense, a human infective strain of the trypanosome parasite, that serve as lead compounds for further optimisation.

MRI CONTRAST AGENTS

The present invention relates to MRI based imaging. In particular, the present invention provides MRI contrast agents targeted to a HaloTag protein with tunable relaxation properties thereby providing optimal relaxivity for low field strength imaging and the other optimal relaxivity for high field strength imaging. Moreover, the MRI contrast agents are used to detect gene expression (of a gene of interest) in real time in vivo, to detect changes in gene expression (of a gene of interest) over time in, for example, an individual organism, to detect gene expression changes (of a gene of interest) in response to therapeutics, in cell labeling for MR imaging, in clinical diagnostics, and in theranostics.

Reporter protein-targeted probes for magnetic resonance imaging

Contrast agents for magnetic resonance imaging are frequently employed as experimental and clinical probes. Drawbacks include low signal sensitivity, fast clearance, and nonspecificity that limit efficacy in experimental imaging. In order to create a bioresponsive MR contrast agent, a series of four Gd(III) complexes targeted to the HaloTag reporter were designed and synthesized. HaloTag is unique among reporter proteins for its specificity, versatility, and the covalent interaction between substrate and protein. In similar systems, these properties produce prolonged in vivo lifetimes and extended imaging opportunities for contrast agents, longer rotational correlation times, and increases in relaxivity (r1) upon binding to the HaloTag protein. In this work we report a new MR contrast probe, 2CHTGd, which forms a covalent bond with its target protein and results in a dramatic increase in sensitivity. A 6-fold increase in r1, from 3.8 to 22 mM-1s-1, is observed upon 2CHTGd binding to the target protein. This probe was designed for use with the HaloTag protein system which allows for a variety of substrates (specific for MRI, florescence, or protein purification applications) to be used with the same reporter.

Tuning the polarity of hierarchically assembled helicates

Catechol ligands bearing ester groups in 3-position (1a,b, 2) are building blocks for the formation of triply lithium-bridged dinuclear helicate-type complexes [Li1a,b,2)i-. Attachment of appropriate functionalities at the ester unit allows the fine tuning of the polarity of the compounds to afford solubility in highly nonpolar as well as highly polar solvents. The investigations show that the internal dinuclear core is stable in a broad variety of solvents, even in water. Georg Thieme Verlag Stuttgart ? New York.
