Here, we have explored the light-up property of coumarin 343 (C343) selectively towards various i-motif DNAs based on the recognition of hemi-protonated cytosine-cytosine base pairing, unlike other DNA structures. We have also demonstrated the versatile ability of this i-motif ligand...

Amyloid beta-protein (Abeta) has been reported to interact with a variety of lipid species, although the thermodynamic driving force remains unclear. We investigated the binding of Abetas labeled with the dye diethylaminocoumarin (DAC-Abetas) to lipid bilayers under various conditions. DAC-Abeta-(1-40)...

The photophysical properties of 7-(diethylamino) coumarin-3-carboxylic acid (7-DCCA) were studied in cyclodextrins (α, β, γ,-CDs), different neat solvents and solvent mixtures by using steady state absorption, emission and time-resolved fluorescence spectroscopy. We have observed that with gradual increase in concentration...

Nanothermometers composed from a gold nanorod core, temperature sensitive linker and fluorescent dye are reported. The nanothermometers have low fluorescence due to a self-quenching mechanism at temperatures below 50 °C and become highly fluorescence above 70 °C.

We report methods to synthesize sub-micron- and micron-sized patchy silica particles with fluorescently labeled hemispherical titania protrusions, as well as routes to efficiently characterize these particles and self-assemble these particles into non-close-packed structures. The synthesis methods expand upon earlier work...

GM1 ganglioside-bound amyloid beta-protein (GM1-Abeta), found in brains exhibiting early pathological changes of Alzheimer's disease (AD) plaques, has been suggested to accelerate amyloid fibril formation by acting as a seed. We have previously found using dye-labeled Abeta that Abeta recognizes...

FEBS letters, 580(28-29), 6587-6595 (2006-11-28)
The formation of fibrils by amyloid beta-protein (Abeta) is considered as a key step in the pathology of Alzheimer's disease (AD). Inhibiting the aggregation of Abeta is a promising approach for AD therapy. In this study, we used biocompatible nanogels...

Cell-penetrating peptides (CPPs) are well established as delivery agents for otherwise cell-impermeable cargos. CPPs can also theoretically be used to modulate intracellular processes. However, their susceptibility to proteolytic degradation often limits their utility in these applications. Previous studies have explored...

A single-stranded DNA binding protein (SSB), labeled with a fluorophore, interacts with single-stranded DNA (ssDNA), giving a 6-fold increase in fluorescence. The labeled protein is the adduct of the G26C mutant of the homotetrameric SSB from Escherichia coli and a...

Quantitation of metabolic parameters using the technique of cardiac surface fluorescence is complicated by motion and changes in tissue absorption. Because ratio fluorescence methodology can be applied to eliminate motion-induced errors, in the current study, we used a ratio fluorescence...

Urinary incontinence is a significant challenge for women who are affected by it. We propose augmenting the tissue structure to restore normal biomechanics by molecularly engineering the tissue using a novel family of biomimetic proteoglycans (BPGs). This work examines the...

GM1 ganglioside-bound amyloid beta-protein (GM1/Abeta), found in brains exhibiting early pathological changes of Alzheimer's disease (AD) including diffuse plaques, has been suggested to be involved in the initiation of amyloid fibril formation in vivo by acting as a seed. To...

The structure of 7-(N,N'-diethylamino)-coumarin-3-carboxylic acid (DCCA) was verified by single crystal X-ray crystallography. The UV-vis absorption and fluorescence of DCCA were discussed. The compound exhibits strong blue emission under ultraviolet light excitation. The molecular structure of DCCA was optimized using...

The major acid-soluble protein components of the mussel Mytilus galloprovincialis sperm chromatin consist of the protamine-like proteins PL-II, PL-III and PL-IV, an intermediate group of sperm nuclear basic proteins between histones and protamines. The aim of this study was to...

Four new maleimide derivatives, antrocinnamomins E-H (1-4, resp.), together with (3S,4R)-1-hydroxy-3-(4-hydroxyphenyl)-4-(2-methylpropyl)pyrrolidine-2,5-dione (5) and ergosterol were isolated from the mycelia of Antrodia cinnamomea BCRC 36799. The structures were elucidated by 1D- and 2D-NMR spectroscopy, and mass spectrometry. Compounds 1-5 were evaluated...
