Abstract
Luminescence imaging is a powerful and versatile technique for investigating cell physiology and pathology in living systems, making significant contributions to life science research and clinical diagnosis. In recent years, luminescent transition metal complexes have gained significant attention for diagnostic and therapeutic applications due to their unique photophysical and photochemical properties. In this Review, we provide a comprehensive overview of the recent development of luminescent transition metal complexes for bioimaging and biosensing applications, with a focus on transition metal centers with a d6, d8, and d10 electronic configuration. We elucidate the structure-property relationships of luminescent transition metal complexes, exploring how their structural characteristics can be manipulated to control their biological behavior such as cellular uptake, localization, biocompatibility, pharmacokinetics, and biodistribution. Furthermore, we introduce the various design strategies that leverage the interesting photophysical properties of luminescent transition metal complexes for a wide variety of biological applications, including autofluorescence-free imaging, multimodal imaging, organelle imaging, biological sensing, microenvironment monitoring, bioorthogonal labeling, bacterial imaging, and cell viability assessment. Finally, we provide insights into the challenges and perspectives of luminescent transition metal complexes for bioimaging and biosensing applications, as well as their use in disease diagnosis and treatment evaluation.

Abstract
Cancer stem cells are pivotal players in tumors initiation, growth, and metastasis. While several markers have been identified, there remain challenges particularly in heterogeneous malignancies like adult soft tissue sarcomas, where conventional markers are inherently overexpressed. Here, we designed BODIPY scaffold fluorescence probes (BD-IMC-1, BD-IMC-2) that activate via disaggregation targeting for cyclooxygenase (COX), a potential marker for CSCs in sarcoma in clinical pathology. Based on their structures, BD-IMC-1 showcased higher susceptibility to disaggregation compared to BD-IMC-2, consistent with their selective interaction with COX. Notably, the BD-IMC-1 revealed positive cooperativity binding to COX-2 at sub-micromolar ranges. Both probes showed significant fluorescence turn-on upon LPS or PMA triggered COX-2 upregulation in live RAW264.7, HeLa, and human sarcoma cell line (Saos-LM2) up to 2-fold increase with negligible toxicity. More importantly, the BD-IMC-1 demonstrated their practical imaging for COX-2 positive cells in paraffin-fixed human sarcoma tissue. Considering the fixed tissues are most practiced pathological sample, our finding suggests a potential of disaggregation activated chemosensor for clinical applications.

Abstract
Cyclooxygenase-2 (COX-2) fluorescent probes are promising tools for early diagnosis of cancer. Traditionally, COX-2 probes were designed by connecting two parts, a fluorophore and a COX-2 binding unit, via a flexible linker. Herein, a new class of COX-2-specific fluorescent probes have been developed via one-step modification from rofecoxib by an integrative approach to combine the binding unit and the fluorophore into one. Among them, several new rofecoxib analogues not only exhibited still potent COX-2 binding ability but also exhibited attractive fluorescence properties, such as tunable blue-red emission, solvatochromism, aggression-induced emission behavior, and mechanochromism. Notably, the emission of 2a16 can be switched between green-yellow in the crystalline state and red-orange in the amorphous state by grinding and fuming treatments. Furthermore, the highly fluorescent compound 2a16 (Φf = 0.94 in powder) displayed a much stronger fluorescence imaging of COX-2 in HeLa cancer cells overexpressing COX-2 than RAW264.7 normal cells with a minimal expression of COX-2. Most importantly, 2a16 can light up human cancer tissues from adjacent normal tissues with a much brighter fluorescence by targeting the COX-2 enzyme. These results demonstrated the potential of 2a16 as a new red fluorescent probe for human cancer imaging in clinical applications.

Abstract
The real motivation in the present work is to tune the synthesis variables that can result in a highly fluorescent and stable DNA copper nanocluster (CuNC) and also to understand the intricate mechanism behind this process. Here, carefully optimized concentrations of various reactants enabled the creation of a DNA-encapsulated CuNC for AT-DNA, displaying a size of <1.0 nm as confirmed by transmission electron microscopy and dynamic light scattering. The extremely small size of the AT-DNACuNC supports the discrete electronic transitions, also characterized by an exceptionally strong negative circular dichroism (CD) band around 350 nm, whose intensity is well correlated with the observed strong fluorescence emission intensity. This remarkably strong CD can open new applications in the detection and quantification of a specific DNACuNC. Further, time-dependent fluorescence analysis suggested stronger photostabilization of these DNACuNCs. The simulation study, based on Cu ion distribution, explained how AT-DNA is a better candidate for NC formation than GC-DNA. In conclusion, the better-tuned synthesis procedure has resulted in a highly compact, well-defined three-dimensional conformation that promotes a more favorable microenvironment to sequester a DNA-based CuNC with high brightness and outstanding photostability.

Abstract
We report the design, preparation and characterisation of three small-molecule, Formyl Peptide Receptor (FPR)-targeted lanthanide complexes (Tb·14, Eu·14 and Gd·14). Long-lived, metal-based emission was observed from the terbium complex (τH2O = 1.9 ms), whereas only negligible lanthanide signals were detected in the europium analogue. Ligand-centred emission was investigated using Gd·14 at room temperature and 77 K, leading to the postulation that metal emission may be sensitised via a ligand-based charge transfer state of the targeting Quin C1 unit. Comparatively high longitudinal relaxivity values (r1) for octadentate metal complexes of Gd·14 were determined (6.9 mM-1 s-1 at 400 MHz and 294 K), which could be a result of a relative increase in twisted square antiprism (TSAP) isomer prevalence compared to typical DOTA constructs (as evidenced by NMR spectroscopy). In vitro validation of concentration responses of Tb·14via three key neutrophil functional assays demonstrated that the inflammatory responses of neutrophils (i.e. chemotaxis, transmigration and granular release) remained unchanged in the presence of specific concentrations of the compound. Using a time-resolved microscopy set-up we were able to observe binding of the Tb·14 probe to stimulated human neutrophils around the cell periphery, while in the same experiment with un-activated neutrophils, no metal-based signals were detected. Our results demonstrate the utility of Tb·14 for time-resolved microscopy with lifetimes several orders of magnitude longer than autofluorescent signals and a preferential uptake in stimulated neutrophils.

Abstract
Background:
Four major degradation products (1-4) of pralatrexate injection were formed
under hydrolytic and light stress conditions. The impurities 1 and 2 were the potential photo degradation
products and the impurities 3 and 4 were the potential hydrolytic degradation products.
Objective:
To prepare and characterize the novel degradation impurities 1, 2, 3 and 4 of pralatrexate
injection using NMR, HR MS and IR techniques; and to develop and validate stability indicating analytical
reverse phase HPLC-UV method for quantitative simultaneous determination of potential
degradation impurities, related substances of pralatrexate and pralatrexate active in pralatrexate liquid
formulation.
Methods:
Gradient HPLC-UV method was developed for the quantification of degradation impurities,
related substances and pralatrexate in pralatrexate injection. The separation was achieved on C18 column
(250 mm X 4.6 mm, 5µm) using a mobile phase composed of sodium dihydrogen phosphate
monohydrate in water (pH 3.0; 0.01M) and methanol. The components were monitored by the UVvisible
detector at 242 nm with a flow rate of 1.0 mL/min.
Results:
The method validation parameters such as accuracy, selectivity, linearity, LOD, LOQ, precision,
ruggedness and robustness were demonstrated successfully for pralatrexate and its degradation
impurities. The stability-indicating capability of the developed HPLC method was demonstrated by
adequate separation of all potential pralatrexate related substances from pralatrexate stressed drug
product samples.
Conclusion:
The developed stability indicating HPLC method was found to be suitable for the simultaneous
quantitative determination of potential degradation impurities and related substances of pralatrexate
and pralatrexate active in pralatrexate liquid formulation.

Abstract
Simultaneous detection of free and complexed prostate-specific antigen (f-PSA and c-PSA) is critical to the prostate cancer (PCa) diagnostic accuracy for clinical samples with PSA values in the diagnostic gray zone between 4 and 10 ng mL-1. Herein, red and green magnetic-quantum dot nanobeads (MQBs) with superior magnetic property and high luminescence were fabricated via polyethyleneimine-mediated electrostatic adsorption of numerous quantum dots onto superparamagnetic Fe3O4 magnetic cores, and were conjugated with f-PSA antibody and c-PSA antibody, respectively, as versatile fluorescent probes in test strip for immune recognition, magnetic enrichment, and simultaneous detection of f-PSA and c-PSA analytes in complex biological matrix with t-PSA antibody on the test line. A low-cost and portable smartphone readout device with an application was also developed for the imaging of dual-color test strips and data processing. This assay can simultaneously detect f-PSA and c-PSA with the limits of detection of 0.009 ng mL-1 and 0.087 ng mL-1, respectively. Clinical serum samples of PCa and benign prostatic hyperplasia patients were evaluated to confirm the clinical feasibility. The results suggest that the proposed dual-color MQBs-based fluorescent lateral flow immunoassay is a promising point-of-care diagnostics technique for the accurate diagnosis of PCa even in resource-limited settings.

Abstract
Two rhodamine-modified half-sandwich Ir(III) complexes with the general formula [(Cpx)Ir(ĈN) Cl] were synthesized and characterized, where Cpx is 1-biphenyl-2,3,4,5-tetramethylcyclopentadienyl (Cpxbiph). Both complexes showed potent anticancer activity against A549, HeLa, and HepG2 cancer cells and normal cells, and altered ligands had an effect on proliferation resistance. The complex enters cells through energy dependence, and because of the different ligands, not only could it affect the anticancer ability of the complex but also could affect the degree of complex lysosome targeting, lysosomal damage, and further prove the antiproliferative mechanism of the complex. Excitingly, antimetastatic experiments demonstrated that complex 1 has the ability to block the migration of cancer cells. Furthermore, although the complex did not show a stronger ability to interfere with the coenzyme NAD+/NADH pair by transfer hydrogenation, the intracellular reactive oxygen species (ROS) content has shown a marked increase. NF-κB activity is increased by ROS regulation, and the role of ROS-NF-κB signaling pathway further induces apoptosis. Moreover, cell flow experiments also demonstrated that complex 1 blocked the cell cycle in S phase, but the complex did not cause significant changes in the mitochondrial membrane potential.

Abstract
In this work, five naphthalimide-modified half-sandwich iridium and ruthenium complexes ([(η5-Cpx)Ir(NˆN)Cl]PF6, [(η6-p-cym)Ru(NˆN)Cl]PF6) have been presented. The anticancer activities of the complexes against various cancer cell lines were investigated, among them, complexes 2 and 4 showed better anticancer activity than cisplatin, and their anticancer activity is better than complex 5 without fluorophore. In addition, a series of biological tests of complex 2 were performed using flow cytometry, the results indicated that the complex could induce cell death in a variety of ways. By changing of the ligands, the complexes exhibited different photophysical properties, and the mechanism of action of the complexes entering the cell and inducing apoptosis are different. Moreover, complex 2 successfully targeted mitochondria, while complex 4 targeted lysosomes, causing mitochondrial damage and lysosomal damage to induce apoptosis. Excitingly, complex 2 has good antimetastatic ability to cancer cells. Furthermore, complexes 2 and 4 did not have a significant effect on the NADH binding reaction, but they had a moderate binding ability to BSA.

Abstract
Background:
Monitoring of plasma concentrations is a necessity for narrow therapeutic index
potent drugs. Development of non-invasive methods can save the patients from the trauma of needles
and hence is considered as a research priority.
Introduction:
Gabapentin, an anti-epileptic drug requires therapeutic monitoring because of its narrow
therapeutic index. The objective of the study was to develop a suitable method for the non-invasive
extraction of gabapentin for the same.
Methods:
Transdermal reverse iontophoresis was performed using pig ear skin as a barrier membrane.
Three compartment iontophoretic cells were used for the extraction study. Extractions were carried out
under low intensity electric field (current intensity- 0.5 mA/cm2, electrical field approximately 5 V).
The donor compartment was charged with aqueous gabapentin (10 µg/ml in phosphate buffer of pH
7.4). For studying the effect of receiving vehicle (pH, ionic strength, and enhancer) on the extraction
efficiency of gabapentin, the two receiver chambers were charged with media having varying concentration
of these factors. Drug content was determined by HPLC.
Results:
Compared to other pHs, cumulative extraction of gabapentin at pH 5 was significantly higher
at both anode and cathode (p<0.001). At low ionic strength, extraction of gabapentin increased linearly
with the increase in concentration of ions up to a certain value but at very high ionic strength the pattern
reversed. Similar results were obtained with enhancer (polyethylene glycol 400). Extraction increased
with increase in polyethylene glycol 400 up to 3% and then decreased.
Conclusion:
Extraction flux can be optimized by manipulation of the receiver media.

Abstract
Alagille syndrome (ALGS) is primarily caused by jagged1 (JAG1) mutations, 70% of which are protein‑truncating mutations. However, no mutation hotspots have been discovered, and the pathogenic mechanism is not fully understood. The aim of the present study was to analyze two protein‑truncating JAG1 mutations detected in three Chinese ALGS patients. Mutation c.1261delT (p.Cys421Valfs) was identified in one patient with hepatic damage, xanthomas, facial abnormalities and cardiovascular defects, which was inherited from his father. The other mutation, c.1382_1383delAC (p.Asp461Glyfs), carried by a pair of monozygotic twins with hepatic damage, facial abnormalities and cardiovascular defects, was de novo. Biological experiments were performed to study the characteristics and function of these mutations. The p.Cys421Valfs and p.Asp461Glyfs mutant proteins appeared to be truncated in western blotting using anti‑Flag bound to the N‑terminus of JAG1. The RBP‑Jκ‑responsive reporter gene assay was used to investigate the ability of mutant JAG1 proteins to activate the Notch signaling pathway. The mutant proteins had a lower luciferase activity than the wild‑type, indicating impaired transcriptional activation ability. Western blotting using soluble JAG1 from the culture medium revealed that the expression levels of the mutant proteins were lower than that of the wild‑type, suggesting that less mutant JAG1 protein underwent proteolytic cleavage than the wild‑type. In conclusion, these two loss‑of‑function JAG1 mutations may be associated with ALGS manifestations in these patients.

Abstract
Targeting cyclooxygenase-2 (COX-2) for molecular imaging is an attractive approach applicable for its overexpression in inflammation and many malignancies. Herein, for monitoring COX-2, we synthesize a specific COX-2 probe celecoxib-MPA probe (CMP), based on celecoxib and a water-soluble near-infrared dye dye ICG-Der-02 (MPA). Its high affinity for binding to COX-2 is verified by molecular docking, dynamics simulation and inhibition assay. At cellular level, CMP selectively accumulates in cytoplasm of COX-2-positive cells. in vivo assays, probe guided-imaging in inflamed or cancerous tissues confirms that CMP can bind to the locally endogenic COX-2 and exhibit intense fluorescence. Importantly, we further prove the targeting specificity of CMP as the fluorescence is significantly reduced by blocking COX-2 active site through preinjection with celecoxib. The results suggest that the probe CMP, with favorable hydrophilic property, good biocompatibility, long-term observation, excellent targeting ability and optical imaging capability, could serve as a promising probe for real-time monitoring COX-2 in inflammation and tumor.

Abstract
This study describes an aptamer based assay for the mycotoxin ochratoxin A (OTA). The method is based on the use of an OTA-specific aptamer, exonuclease (Exo) III, SYBR Gold as a fluorescent probe, and a complementary strand that specifically combines with the aptamer. In the presence of OTA, the aptamer and OTA hybridize, thereby resulting in the formation of ssDNA, which is not digested by Exo III. Intense fluorescence is observed after addition of SYBR Gold (best measured at excitation/emission wavelengths of 495/540 nm). Fluorescence increases linearly with the log of the OTA concentration in the range from 8 to 1000 ng·mL-1. The detection limit is 4.7 ng·mL-1. The assay was applied to the determination of OTA in diluted [2%(v/v)] red wine, and recoveries and RSDs ranged between 93.5% and 113.8%, and between 3.2% and 5.7%, respectively. Graphical abstract In the presence of ochratoxin A (OTA), specific combinations of aptamer and OTA may occur and result in DNA double strands being untied, which avoids being digested by Exo III. Intense fluorescence is observed after SYBR Gold addition.

Abstract
A series of luminescent iridium(iii) complexes were synthesized and evaluated for their ability to interact with hydroxide ions in semi-aqueous media at ambient temperature. Upon the addition of OH-, a nucleophilic aromatic substitution reaction takes place at the bromine groups of the N^N ligand of complex 1, resulting in the generation of a yellow-green luminescence. Complex 1 showed a 35-fold enhanced emission at pH 14 when compared to neutral pH, and the detection limit for OH- ions was 4.96 μM. Complex 1 exhibited high sensitivity and selectivity, long-lived luminescence and impressive stability. Additionally, we have demonstrated the practical application of complex 1 to detect OH- ions in simulated wastewater.

Am J Cancer Res 2018; 8:1798-1807. [PMID: 29556357 PMCID: PMC5858501 DOI: 10.7150/thno.22481] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2017] [Accepted: 02/02/2018] [Indexed: 12/15/2022] Open
Abstract
Rationale: Hydrogen peroxide (H2O2) provides an important mechanism for resisting infectious pathogens within the respiratory tract, and accordingly, the in situ analysis of H2O2 generation in real time provides a valuable tool for assessing immune response. Methods: In this study, we applied a chemiluminescent nanoparticle-based real-time imaging approach to noninvasive evaluation of the Duox2-mediated H2O2 generation after viral infection, and assessed its usefulness for analytical purposes in mouse nasal mucosa. The chemiluminescent nanoprobe employed herein (BioNT) possesses appropriate physicochemical properties, such as high sensitivity and selectivity toward H2O2, no background noise, deliverability to the respiratory tract, and capability of multiple injections to a single animal subject for long-term repetitive imaging. Results: The favorable characteristics of BioNT allowed for a longitudinal study with the same mice to noninvasively evaluate the long-term evolution of endogenous H2O2 in the nasal epithelium after infection with influenza A virus (WS/33/H1N1). We found that nasal epithelial cells by themselves respond to viral infection by generating H2O2, and that the in vivo cumulative H2O2 level in the nasal mucosa peaks at day 3 post-infection. Such in vitro and in vivo temporal behaviors of the endogenous H2O2 generation showed a good correlation with those of Duox2 expression after infection. This correlation could be further confirmed with Duox2-deficient subjects (Duox2-knockdown NHNE cells and Duox2-knockout mutant mice) where no H2O2-induced chemiluminescence was detectable even after viral infection. Importantly, upon knock-down of Duox2 expression, the condition of mice caused by viral infection in the upper airway was significantly aggravated, evidencing the involvement of Duox2 in the immune defense. Conclusion: All these results reveal a critical role of Duox2 in the infection-induced H2O2 production and the H2O2-mediated immune response to infection in the respiratory tract, well elucidating the potential of BioNT as a noninvasive tool for fundamental in vivo studies of infectious diseases.

Veratramine modulates AP-1-dependent gene transcription by directly binding to programmable DNA. Nucleic Acids Res 2018; 46:546-557.

Abstract
Because the transcription factor activator protein-1 (AP-1) regulates a variety of protein-encoding genes, it is a participant in many cellular functions, including proliferation, transformation, epithelial mesenchymal transition (EMT), and apoptosis. Inhibitors targeting AP-1 have potential use in the treatment of cancer and other inflammatory diseases. Here, we identify veratramine as a potent natural modulator of AP-1, which selectively binds to a specific site (TRE 5'-TGACTCA-3') of the AP-1 target DNA sequence and regulates AP-1-dependent gene transcription without interfering with cystosolic signaling cascades that might lead to AP-1 activation. Moreover, RNA-seq experiments demonstrate that veratramine does not act on the Hedgehog signaling pathway in contrast to its analogue, cyclopamine, and likely does not harbor the same teratogenicity and toxicity. Additionally, veratramine effectively suppresses EGF-induced AP-1 transactivation and transformation of JB6 P+ cells. Finally, we demonstrate that veratramine inhibits solar-ultraviolet-induced AP-1 activation in mice. The identification of veratramine and new findings in its specific regulation of AP-1 down stream genes pave ways to discovering and designing regulators to regulate transcription factor.

Abstract
A long-lived complex 13 could selectively bind to dopamine receptors (D1R/D2R) and monitor their internalization in living cells.
Dopamine receptor expression is correlated with certain types of cancers, including lung, breast and colon cancers. In this study, we report luminescent iridium(iii) complexes (11–14) as intracellular dopamine receptor (D1R/D2R) cell imaging agents. Complexes 11 and 13, which are conjugated with a dopamine receptor agonist, showed superior cell imaging characteristics, high stability and low cytotoxicity (>100 μM) in A549 lung cancer cells. siRNA knockdown and dopamine competitive assays indicated that complexes 11 and 13 could selectively bind to dopamine receptors (D1R/D2R) in A549 cells. Fluorescence lifetime microscopy demonstrated that complex 13 has a longer luminescence lifetime at the wavelength of 560–650 nm than DAPI and other chromophores in biological fluids. The long luminescence lifetime of complex 13 not only provides an opportunity for efficient dopamine receptor tracking in biological media, but also enables the temporal separation of the probe signal from the intense background signal by fluorescence lifetime microscopy for efficient analysis. Complex 13 also shows high photostability, which could allow it to be employed for long-term cellular imaging. Furthermore, complex 13 could selectively track the internalization process of dopamine receptors (D1R/D2R) in living cells. To the best of our knowledge, complex 13 is the first metal-based compound that has been used to monitor intracellular dopamine receptors in living cells.

Abstract
We have developed a Ag@Au core-shell nanoparticle (NP)/iridium(III) complex-based sensing platform for the sensitive luminescence "turn-on" sensing of cyanide ions, an acutely toxic pollutant. The assay is based on the quenching effect of Ag@Au NPs on the emission of complex 1, but luminescence is restored after the addition of cyanide anions due to their ability to dissolve the Au shell. Our sensing platform exhibited a high sensitivity toward cyanide anions with a detection limit of 0.036 μM, and also showed high selectivity for cyanide over 10-fold excess amounts of other anions. The sensing platform was also successfully applied to monitor cyanide anions in drinking water and in living cells.

Abstract
We developed a novel "signal-off" photoelectrochemical (PEC) aptasensor based on an aptamer bridged DNA network structure for the sensitive detection of vascular endothelial growth factor (VEGF165), using g-C3N4 as photoactive material. The DNA network provides an excellent platform for the immobilization of methylene blue (MB), which can facilitate the electron transport through the DNA helix structure and suppress the recombination of electron-hole pairs generated by g-C3N4. In the presence of the target VEGF165, the DNA network can be destroyed adequately by the recognition between VEGF165 and the aptamer, resulting in the release of MB. Therefore, the originally enhanced electron transfer process could be inhibited, leading to a remarkable decrease of the photocurrent. A good linear relationship between the PEC signal and the logarithm of VEGF165 concentration over the range of 100fM to 10nM with a detection limit of 30 fM can be obtained. Our concept can be easily extended to develop aptasensors for the sensitive detection of different targets by triggering the release of the payloads from their corresponding aptamer bridged DNA networks.

Abstract
Quantitation of plasma membrane proteins (PMPs) is fundamental and frequently performed daily in the lab. However, challenged by the inherent/interacting heterostructures and complex surroundings of the PMPs in lipid membrane, quantitative techniques for PMP often require complex treatments (e.g., labeling, isolation, purification, and determination), and the sensitivity is usually not satisfactory. To address this problem, we have proposed a novel method that enables quantitation of PMPs with extremely high sensitivity, in an easier-to-manipulate and more streamlined way. This method is based on the design of an in situ rolling cycling replication-templated amplification strategy (isRTA). In fact, two rounds of DNA cascade isothermal amplifications have been conducted. The first round of amplification can provide templates for the second round of amplification; thus, significant enhancement of quantitative signals can be achieved. In this way, PMPs are quantified with ultrahigh sensitivity; as few as 25 copies of PMPs can be detected per cell. Moreover, the advantages of isRTA have been demonstrated by simultaneous identification of several PMP biomarkers (MUC1, EpCAM, and HER2) that are expressed over a wide distribution range on breast cancer cells. The precise typing of breast cancer cell subsets is thus possible because of the "quantitative-to-qualitative" strategy. Therefore, the unprecedented sensitivity and high usability of the isRTA method may present significant prospects for delving into membrane proteins and their related biofunctions in many research fields.
