Abstract
We studied the in vitro rate of fluorescent advanced glycation end products (fAGEs) formation with multiphoton microscopy in different porcine tissues (aorta, cornea, kidney, dermis, and tendon). These tissues were treated with d-glucose, d-galactose, and d-fructose, three primary monosaccharides found in human diets. We found that the use of d-fructose resulted in the highest glycation rate, followed by d-galactose and then d-glucose. Moreover, compared to non-collagen tissue constituents such as elastic fibers and cells, the rate of tissue glycation was consistently higher in collagen, suggesting that collagen is a more sensitive target for fAGE formation. However, we also found that collagen in different tissues exhibits different rates of fAGE formation, with slower rates observed in tightly packed tissues such as cornea and tendon. Our study suggests that for fAGE to be developed into a long-term glycemic biomarker, loosely organized collagen tissues located in the proximity of vasculature may be the best targets.

Abstract
The flavin adenine dinucleotide (FAD) is an indispensable coenzyme in live cells. It acts as a catalyst in many redox responsive metabolic reactions, including oxidative phosphorylation in mitochondria. The real-time monitoring of flavin is important to understand the disorder in the metabolic process, redox system, etc. Thus, we have developed a fluorescent probe CPy-1 that noncovalently binds with flavin to exhibit the FRET process. 1H- NMR and docking study indicated that there is a strong hydrophobic interaction between flavins and CPy-1. Also, a π-π stacking between isoalloxazine ring in flavin and quinoline and coumarin moieties of CPy-1 favors self-assembly. The nontoxic probe CPy-1 could distinguish cancer cells from normal cells based on expressions of endogenous FAD.

Effective and prolonged targeting of a nanocarrier to the inflammation site by functionalization with ZnBPMP and chitosan. MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2021; 131:112521. [PMID: 34857300 DOI: 10.1016/j.msec.2021.112521] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 10/19/2021] [Accepted: 10/22/2021] [Indexed: 02/07/2023]
Abstract
Efficient and selective targeting of inflamed tissues/organs is critical for diagnosis and therapy. Although nanomaterials themselves have an intrinsic advantage due to their size for targeting inflammation sites, additional functionalization of the nanomaterials with proper targeting moieties is desired to enhance the targeting efficiency. In this study, we aimed to improve the inflammation targeting characteristics of a pluronic-based nanocarrier, which has advantages as a nanosized delivery cargo for diverse molecules, by conjugating with chitosan and ZnBPMP (two Zn(II) ions chelated 2,6-bis[(bis(2-pyridylmethyl)amino)-methyl]-4-methylphenol) moiety. Specific and significant cellular uptake and interaction between the nanocarrier functionalized with ZnBPMP ligand and chitosan to an apoptosis-induced immune cell line were observed in vitro. An inflammation model in the mouse ear caused by skin hypersensitivity was used to evaluate the effect of functionalization with chitosan and ZnBPMP moiety by comparing with various control groups. Functionalization of the nanocarrier with chitosan greatly enhanced the in vivo circulation time of the nanocarrier, so prolonged targeting ability of the nanocarrier to the inflamed ear was achieved. Additional ZnBPMP functionalization to chitosan-functionalized nanocarrier also resulted in significantly improved initial targeting and further enhancement in the targeting until 5 days to the inflamed ear and the decreased non-specific accumulation of the nanocarrier to the remaining body. Thus, developed nanocarrier has a high potential as a drug delivery carrier as well as a diagnostic agent to the inflammation sites.

Abstract
The selective removal of Zn2+ from proteins by using a synthetic chelator is a promising therapeutic approach for the treatment of various diseases including cancer. Although the chelation of Zn2+ is well known, its removal from a protein in the presence of potential competing biologically relevant ions such as Cu2+ is hardly explored. Herein we present a peptoid - N-substituted glycine trimer - incorporating a picolyl group at the N-terminus, a non-coordinating but structurally directing benzyl group at the C-terminus and a 2,2':6',2''-terpyridine group in the second position, that selectively binds Zn2+ ions in the presence of excess Cu2+ ions in water. We further demonstrate that this chelator can selectively bind Zn2+ from a pool of excess biologically relevant and competitive ions (Cu2+, Fe3+, Ca2+, Mg2+, Na+, and K+) in a simulated body fluid (SBF), and also its ability to remove Zn2+ from a natural zinc protein domain (PYKCPECGKSFSQKSDLVKHQRTHTG) in a SBF.

Abstract
Herein, we report that assemblies of nucleopeptides selectively sequester ATP in complex conditions (for example, serum and cytosol). We developed assemblies of nucleopeptides that selectively sequester ATP over ADP. Counteracting enzymes interconvert ATP and ADP to modulate the nanostructures formed by the nucleopeptides and the nucleotides. The nucleopeptides, sequestering ATP effectively in cells, slow down efflux pumps in multidrug-resistant cancer cells, thus boosting the efficacy of doxorubicin, an anticancer drug. Investigation of 11 nucleopeptides (including d- and l-enantiomers) yields five more nucleopeptides that differentiate ATP and ADP through either precipitation or gelation. As the first example of assemblies of nucleopeptides that interact with ATP and disrupt intracellular ATP dynamics, this work illustrates the use of supramolecular assemblies to interact with small and essential biological molecules for controlling cell behavior.

Abstract
Electrostatic effects on the redox photochemistry of synthetic probes (1, 2, and 1-Zn) are examined by adjusting the thermodynamic driving force of their oxidation reactions. The redox photochemistry was simply controlled by introducing a zinc binding site (2,2'-dipicolylamine (DPA)) on the coumarin moiety of probe 2. Zinc complexation produced a positively charged environment on the coumarin (1-Zn), which lowered the electron density of a nearby 9 H-xanthene ring, attenuating the auto-oxidation of 1-Zn by 45 % compared with that of probe 1 at 298 K. The positive net charge of 1-Zn also provided an attractive Coulombic force toward the phosphate of flavin mononucleotide and flavin adenine dinucleotide, which lowered the reduction potential of the electron acceptor (isoalloxazine) and improved intermolecular electron transfer from the 9 H-xanthene ring to isoalloxazine. The flavin-mediated oxidation rate of 1-Zn was increased to 1.5 times that of probe 2. Probe 1-Zn showed highly selective sensing behaviour toward flavins, producing an intense brightness (ϵΦF =2.80×103 m-1 cm-1 ) in the long-wavelength regions (λmax =588 nm) upon flavin-mediated oxidation. Furthermore, probes 1-Zn and 2 were successfully applied to eosinophil imaging and the differential diagnosis of eosinophilia; this demonstrates their use as diagnostic tools.

Abstract
A bacterial flavin transferase (ApbE) was recently employed for flavin mononucleotide (FMN) modification on the Na+-translocating NADH:quinone oxidoreductase C (NqrC) protein in the pathogenic Gram-negative bacterium Vibrio cholerae. We employed this unique post-translational modification in mammalian cells and found that the FMN transfer reaction robustly occurred when NqrC and ApbE were genetically targeted in the cytosol of live mammalian cells. Moreover, NqrC expression in the endoplasmic reticulum (NqrC-ER) induced the retro-translocation of NqrC to the cytosol, leading to the proteasome-mediated ER-associated degradation of NqrC, which is considered to be an innate immunological response toward the bacterial protein. This unexpected cellular process of NqrC-ER could be exploited for the construction of an in cellulo proteasome inhibitor screening system, and our proposed approach yielded substantially improved results compared to a previous method. In addition, a truncated version of RnfG (half-RnfG) was found to be potentially useful as a genetically encoded tag for monitoring protein-protein interactions in a specific compartment, even in the ER, in a live cell according to its fluorogenic post-translational modification via ApbE. This new genetically encoded system in mammalian cells should serve as a valuable tool for anticancer drug screening and other applications in molecular and synthetic biology.

Abstract
The terpyridine anthracene ligand was synthesized and characterized. is a ratiometric fluorescent probe for Cd(2+) with a recognition mechanism based on intramolecular charge transfer (ICT). An complex was isolated, and its structure was established using single-crystal XRD. The complex was able to serve as a novel reversible chemosensing ensemble to allow ratiometric response to pyrophosphate (PPi) in aqueous media. Moreover, the fluorescence imaging in living cells from these two emission channels suggested that was a ratiometric probe for Cd(2+), and the in situ generated complex was also a ratiometric ensemble for PPi detection in living cells.

Abstract
A resin-bound dinuclear zinc(II) complex for the selective capture of pyrophosphopeptides is reported. The metal complex binds diphosphate esters over other anionic groups, such as monophosphate esters, sulfate esters, and carboxylic acids, with high specificity. Immobilization of the compound provided a reagent capable of binding and retaining nanomolar quantities of pyrophosphopeptide in the presence of cell lysate. The high affinity and specificity of the reagent makes it an attractive tool for the study of in vivo pyrophosphorylation.

Abstract
Biological anions have often proven to be difficult analytes to differentiate in solution. Many of the anions bear similar structural characteristics and similar charge states. Using a commercially available indicator and AT-PAMAM dendrimers, a sensing ensemble for a number of biological anions was constructed. The system was able to identify each of the different analytes as well as the regioisomers of three different tricarboxylates. The system shows responsiveness to not only functional group identity but also the charge state and identity of the anionic species.

Abstract
BACKGROUND Eosinophils trigger symptoms in allergic rhinitis. New diagnostic methods for identifying nasal eosinophils based on autofluorescence of flavin adenine dinucleotide in eosinophil granules could offer rapid monitoring without fixation or staining. Two-photon excitation is a powerful method for detecting this intrinsic fluorescence. OBJECTIVES To demonstrate the use of 2-photon excited fluorescence (TPEF) to detect eosinophils from nasal mucosa in a proof-of-concept study for a future miniature in vivo imaging instrument. METHODS Thirty subjects with rhinitis were recruited. Results of our standard environmental panel were recorded. Fluorescence images were collected from nasal cytology smears with a 2-photon microscope. Cells were evaluated for intensity and size, and compared with Hansel stains. Correlation of cell count was made by linear regression, diagnostic performance was evaluated at various intensity thresholds, and correlation of nasal eosinophil count to allergic status was done through the Wilcoxon rank-sum test. RESULTS The fluorescence intensity of eosinophils compared with epithelial cells was 13.8 ± 4.3 versus 3.7 ± 1.8 (P < .01), and the size was 27.0 ± 10.2 versus 392.0 ± 214.6 μm2 (P < .01), respectively. Using both fluorescence intensity and size, a total accuracy of 100% is achieved. Eosinophil count on TPEF correlates with Hansel stain, R(2) = 0.91. Nasal eosinophil count correlates with allergic status on both TPEF (P = .008) and Hansel stain images (P = .027). CONCLUSIONS TPEF is a promising novel technique for identifying and quantifying nasal eosinophils on nasal cytology specimens without the need for fixation or staining. Future development of a rhinoscope-compatible 2-photon microscope could be used as a clinical adjunct for the diagnosis and management of rhinitis patients in vivo.

Abstract
A 6-week reciprocal transfer laboratory exposure experiment was conducted with two populations of the epigeic earthworm Dendrodrilus rubidus; one population inhabited a site approx. 200 m downwind of an active Ni smelter co-contaminated with Ni and Cu (3648 and 977 microg g(-1)d.w., respectively), the other inhabited uncontaminated soil. Worms transferred from unpolluted to Ni/Cu-polluted soil lost body mass (62%); they also had reduced (70%) total coelomocyte number, including autofluorescent eleocytes, and had significantly decreased (92%) riboflavin-derived fluorescence emission measured at 525 nm. Coelomocyte counts were low, and 525 nm emission was negligible in worms maintained on their native Ni/Cu soil. Earthworms and their coelomocytes were unaffected when transferred from Ni/Cu-polluted soil to unpolluted soil. In conclusion, exposing worms to stress-inducing factors, including metal pollution, alters the riboflavin status within the immune-competent cells of D. rubidus, but it requires further in vivo studies to establish whether the reduction in the fluorescence signal is predominantly due to depletion of riboflavin-containing eleocytes, or to riboflavin quenching, or to enzymatic conversion (and thus depletion) of stored riboflavin into its functional immune-potentiating flavin derivatives, FMN and FAD. The flavin budget of D. rubidus coelomocytes recovered by a reproducible extrusion procedure is a potentially useful biomarker for assessing sublethal stress in this early colonizer of disturbed soils.

Abstract
In cellular signaling, adenylyl cyclase plays a key role in the hydrolysis of ATP to cyclic AMP and pyrophosphate. Using a synthetic fluorescent chemosensor (PyDPA) which binds strongly to the pyrophosphate group, we have developed a label-free fluorescent real-time detection system for adenylyl cyclase. This assay would be the first adenylyl cyclase assay based on chemosensing the production of pyrophosphate.

Abstract
Flavins, comprising flavin mononucleotide (FMN), flavin adenine dinucleotide (FAD), and riboflavin (RF, vitamin B(2)), play important roles in numerous redox reactions such as those taking place in the electron-transfer chains of mitochondria in all eukaryotes and of plastids in plants. A selective chemosensor for flavins would be useful not only in the investigation of metabolic processes but also in the diagnosis of diseases related to flavins; such a sensor is presently unavailable. Herein, we report the first bifunctional chemosensor (PTZ-DPA) for flavins. PTZ-DPA consists of bis(Zn(2+)-dipicolylamine) and phenothiazine. Bis(Zn(2+)-dipicolylamine) (referred to here as XyDPA) was found to be an excellent catalyst in the conversion of FAD into cyclic FMN (riboflavin 4',5'-cyclic phosphate, cFMN) under physiological conditions, even at pH 7.4 and 27 degrees C, with less than 1 mol % of substrate. Utilizing XyDPA's superior function as an artificial FMN cyclase and phenothiazine as an electron donor able to quench the fluorescence of an isoalloxazine ring, PTZ-DPA enabled selective fluorescent discrimination of flavins (FMN, FAD, and RF): FAD shows ON(+), FMN shows OFF(-), and RF shows NO(0) fluorescence changes upon the addition of PTZ-DPA. With this selective sensing property, PTZ-DPA is applicable to real-time fluorescent monitoring of riboflavin kinase (RF to FMN), alkaline phosphatase (FMN to RF), and FAD synthetase (FMN to FAD).

Abstract
A new thiazoline-containing cobalt(II) complex displayed colorimetric and fluorescent "turn-on" selectivity and sensitivity toward fluoride anions compared to the other anions investigated through color changes from pink to blue and changes in the emission spectra at approximately 570 nm when excited at 520 nm.
