Abstract
Cyclometalated iridium(III) complexes have received considerable attention and are important candidates for use as luminescent probes for cellular imaging because of their potential photophysical properties. We previously reported that fac-Ir(atpy)(3)4 (atpy = 2-(5'-amino-4'-tolyl)pyridine) containing three amino groups at the 5'-position of the atpy ligand shows a maximum red emission (at around 600 nm) under neutral and basic conditions and a green emission (at 531 nm) at acidic pH (pH 3-4). In this Article, we report on the design and synthesis of a new pH-sensitive cyclometalated Ir(III) complex containing a 2-(5'-N,N-diethylamino-4'-tolyl)pyridine (deatpy) ligand, fac-Ir(deatpy)(3)5. The complex exhibits a considerable change in emission intensity between neutral and slightly acidic pH (pH 6.5-7.4). Luminescence microscopic studies using HeLa-S3 cells indicate that 5 can be used to selectively stain lysosome, an acidic organelle in cells. Moreover, complex 5 is capable of generating singlet oxygen in a pH-dependent manner and inducing the death of HeLa-S3 cells upon photoirradiation at 377 or 470 nm.

Abstract
Cell plasma membranes of living cells maintain their asymmetry, so that the outer leaflet presents a large quantity of sphingomyelin, which is critical for formation of ordered lipid domains. Here, a recently developed probe based on Nile Red (NR12S) was applied to monitor changes in the lipid order specifically at the outer leaflet of cell membranes. Important key features of NR12S are its ratiometric response exclusively to lipid order (liquid ordered vs. liquid disordered phase) and not to surface charge, the possibility of using it at very low concentrations (10-20nM) and the very simple staining protocol. Cholesterol extraction, oxidation and sphingomyelin hydrolysis were found to red shift the emission spectrum of NR12S, indicating a decrease in the lipid order at the outer plasma membrane leaflet. Remarkably, apoptosis induced by three different agents (actinomycin D, camptothecin, staurosporine) produced very similar spectroscopic effects, suggesting that apoptosis also significantly decreases the lipid order at this leaflet. The applicability of NR12S to detect apoptosis was further validated by fluorescence microscopy and flow cytometry, using the ratio between the blue and red parts of its emission band. Thus, for the first time, an environment-sensitive probe, sensitive to lipid order, is shown to detect apoptosis, suggesting a new concept in apoptosis sensing.

Abstract
Isoquinoline-based tetradentate ligands with C(3)-symmetry, tris(1- or 3-isoquinolylmethyl)amine (1- or 3-isoTQA), have been prepared and their zinc-induced fluorescence enhancement was investigated. Upon excitation at 324 nm, 1-isoTQA shows very weak fluorescence (ϕ = ∼0.003) in DMF/H(2)O (1/1) solution. In the presence of zinc ion, 1-isoTQA exhibits fluorescence increase (ϕ = 0.041) at 359 and 470 nm. This fluorescence enhancement at 470 nm is specific for zinc. However, 3-isoTQA exhibited a smaller fluorescence enhancement upon zinc complexation (ϕ = 0.017, λ(em) = 360 and 464 nm) compared with 1-isoTQA. Crystal structures of zinc complexes of isoTQAs demonstrate the diminished steric crowding and shorter Zn-N(aromatic) distances compared with isoTQENs (N,N,N',N'-tetrakis(isoquinolylmethyl)ethylenediamines) leads to a higher fluorescent response toward zinc relative to cadmium.

Abstract

We find that H(2)L has high selectivity and sensitivity to detect Zn(2+) ion over other metal ions such as Na(+), Ag(+), Cd(2+), Co(2+), Cr(3+), Cu(2+), Hg(2+), Mn(2+), Ni(2+), Fe(3+), and the sensitivity is about 10(-7)M. The fluorescent changes of H(2)L upon the addition of cations Zn(2+) and triethylamine is utilized as an AND logic gate at the molecular level, using Zn(2+) and triethylamine as chemical inputs and the fluorescence intensity signal as output.

Abstract
Noninvasive magnetic resonance imaging (MRI) including the "chemical shift imaging (CSI)" technique based on (1)H NMR signals is a powerful method for the in vivo imaging of intracellular molecules and for monitoring various biological events. However, it has the drawback of low resolution because of background signals from intrinsic water protons. On the other hand, it is assumed that the (11)B NMR signals which can be applied to a CSI technique have certain advantages, since boron is an ultratrace element in animal cells and tissues. In this manuscript, we report on the sensing of biologically indispensable d-block metal cations such as zinc, copper, iron, cobalt, manganese, and nickel based on (11)B NMR signals of simple phenylboronic acid-pendant cyclen (cyclen = 1,4,7,10-tetraazacyclododecane), L(6) and L(7), in aqueous solution at physiological pH. The results indicate that the carbon-boron bond of L(6) is cleaved upon the addition of Zn(2+) and the broad (11)B NMR signal of L(6) at 31 ppm is shifted upfield to 19 ppm, which corresponds to the signal of B(OH)(3). (1)H NMR, X-ray single crystal structure analysis, and UV absorption spectra also provide support for the carbon-boron bond cleavage of ZnL(6). Because the cellular uptake of L(6) was very small, a more cell-membrane permeable ligand containing the boronic acid ester L(7) was synthesized and investigated for the sensing of d-block metal ions using (11)B NMR. Data on (11)B NMR sensing of Zn(2+) in Jurkat T cells using L(7) is also presented.

Abstract
Previously, we have reported that 1- and 3-isoTQENs (N,N,N',N'-tetrakis(1- or 3-isoquinolylmethyl)ethylenediamines) exhibit a specific fluorescence enhancement toward zinc ion. In this study, three methoxy-substituted derivatives of 1-isoTQEN were synthesized and their fluorescent response toward zinc ion was studied. The substitution pattern of the methoxy group significantly changes the solubility of compounds in aqueous DMF, λ(max) in the absorption spectra, excitation/emission wavelengths and fluorescence intensity of zinc complexes. In the presence of zinc ion, 7-MeO-1-isoTQEN exhibits higher fluorescence intensity and longer excitation/emission wavelengths (λ(ex) = 342 nm, λ(em) = 526 nm) than 6-MeO-1-isoTQEN (λ(ex) = 303 nm, λ(em) = 469 nm) and 5,6,7-triMeO-1-isoTQEN (λ(ex) = 340 nm, λ(em) = 504 nm). The fluorescence intensity of a zinc complex of 7-MeO-1-isoTQEN (ϕ = 0.122) is four times higher than the parent 1-isoTQEN (ϕ = 0.034) under the same conditions. The crystal structure of 7-MeO-1-isoTQEN-Zn complex reveals that all six nitrogen atoms participate to the metal coordination with ideal octahedral geometry, affording significantly high metal binding affinity comparable with TPEN (N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine). 7-MeO-1-isoTQEN detects zinc ion concentration change in cells by fluorescence microscopic analysis.

Abstract
In the past decade, fluorescent chemosensors for zinc ion (Zn(2+)) have attracted great attention because of the biological significance of zinc combined with the simplicity and high sensitivity of fluorescence assays. Chemosensors can be divided into a fluorophore, a spacer and a receptor unit; the receptor is the central processing unit (CPU) of a chemosensor. This tutorial review will classify zinc chemosensors based on receptor types.

Abstract
Changes in the free zinc(II) concentration are closely related to cell proliferation and apoptosis, especially during the early apoptotic process. In the present paper, we demonstrated that zinc(II) probe FluoZin-3AM owns sensitive properties to distinguish different stages of apoptotic cell (induced by an anticancer agent, etoposide) according to trace intracellular zinc(II) fluorescence flux. When apoptosis in HeLa or K562 cells was artificially induced, FluoZin-3AM selectively and strongly stained apoptotic cells only at early and middle stages, which was attributed to significantly increased free zinc(II) flux during these stages. This conclusion was further verified by comparing it with the conventional apoptosis detector probe Annexin-V-FITC and PI. Furthermore, FluoZin-3AM was found cell permeable to detect the intracellular zinc(II) fluorescence enhancement to threefolds within 120 s with low cytotoxicity when zinc(II) was incorporated into the cell by zinc(II) ionophore pyrithione. All the above implied that monitoring intracellular zinc fluorescence flux was an effective method to distinguish cell apoptosis from necrosis, and FluoZin-3AM was found to be a suitable probe acting alone to fulfill the work.

Abstract
We report the design and synthesis of a novel class of asymmetrically functionalized, ditopic bis-dipicolylamine (BDPA) ligands. A key feature of this research involved the controlled, sequential functional group decoration of a potent molecular recognition scaffold. Calorimetric screening identified a BDPA analogue as a highly potent (K(a) approximately 10(6) M(-1)) and selective sensor for inorganic phosphate.

Abstract
Sulfonamide constitutes a ubiquitous functional group that is frequently used in organic chemistry, analytical chemistry, and medicinal chemistry. We report herein on the photolysis of a dansylamide moiety of 1-dansyl-1,4,7,10-tetraazzacyclododecane (N-dansylcyclen, L(2)) in the presence of a zinc(II) ion in aqueous solution. By potentiometric pH titrations, the complexation constant for the 1:1 complex of L(2) and Zn(2+), log K(s)(ZnL(2)), in aqueous solution at 25 degrees C with I = 0.1 (NaNO(3)) was determined to be 6.5+/-0.1. The structure of the ZnL(2) complex was confirmed by single-crystal X-ray diffraction analysis. During fluorescence titrations of L(2) with Zn(2+) (irradiation at 308 or 350 nm) in aqueous solution at pH 7.4 (10 mM HEPES with I = 0.1 (NaNO(3))) and 25 degrees C, considerable enhancement in fluorescence emission of the Zn(2+) complex of L(2) (ZnL(2)) was observed, while metal-free L(2) exhibited only a negligible emission change upon UV irradiation. It was revealed that this emission enhancement arose from the photoinduced cleavage of a sulfonylamide moiety in ZnL(2), yielding the Zn(2+)-cyclen complex and 5-dimethylaminonaphthalene-1-sulfinic acid, which has a greater quantum yield (Phi) for fluorescence emission than that of L(2) and ZnL(2). For comparison, the photolysis of N-(1-naphthalenesulfonyl)cyclen (L(3)) and its Zn(2+) complex (ZnL(3)) under the same conditions (irradiation at 313 nm) gave the corresponding sulfonate (1-naphthylsulfonate). We also describe the results of a photoreversion reaction of cis,syn-cyclobutane thymine photodimer (T[c,s]T) utilizing the photolysis of ZnL(2) and ZnL(3).

Abstract
The ability of avidin (Avn) to form strong complex with biotin (Btn) is frequently used in the detection and isolation of biomolecules in biochemical, analytical, and medicinal research. The fact that the binding is nealy irreversible, however, constitutes a drawback in term of the isolation and purification of intact biomolecules. We recently found that 8-quinolinyl esters of aromatic or aliphatic sulfonic acids undergo photolysis when irradiated at 300-330 nm in aqueous solution at neutral pH. In this work, a biotin-dopamine (BD) conjugate containing a photocleavable 8-quinolinyl benzenesulfonate (QB) linker, BDQB, was designed and synthesized for use in the efficient recovery of dopamine-protein (e.g., antibody) complexes from an Avn-Btn system. The complexation of BDQB with a primary anti-dopamine antibody (anti-dopamine IgG(1) from mouse) on an Avn-coated plate was confirmed by an enzyme-linked immunosorbent assay (ELISA) utilizing a secondary antibody (anti-IgG(1) antibody) conjugated with horseradish peroxidase (HRP). Upon the photoirradiation (at 313 nm) of the BDQB-IgG(1) complex, the release of dopamine-IgG(1) complex was confirmed by ELISA. Characterization of the resulting photoreleased dopamine-anti-dopamine IgG(1) complex was performed by SDS-PAGE and Western blot.

Abstract
A cyclam-based macrocyclic sensor has been prepared using synthetically simple "click" chemistry to link a fluorophore to the macrocyclic receptor. This sensor shows high selectivity for Zn(II) over a range of other metals, providing a significant enhancement of fluorescence intensity over a wide pH range. As such, this is the first cyclam-based sensor demonstrated to be selective for Zn(II) and is the first example of a triazole being used as a coordinating ligand on an azamacrocycle. The sensor can access biologically available zinc in mammalian cells, sensing the Zn(II) flux that exists during apoptotic cell death.

Abstract
Oxidative stress may cause endothelial dysfunction and vascular disease. It has been shown that NO protects endothelial cells (EC) against H(2)O(2)-induced toxicity. In addition, it is known that NO within cells induces a zinc release from proteins containing zinc-sulfur complexes. The aim of this study was to investigate whether zinc released intracellularly by NO plays a signaling role in the NO-mediated protection against H(2)O(2) in rat aortic EC. Our results show that the NO-mediated protection toward H(2)O(2) depends on the activities of glutathione peroxidase and glutamate cysteine ligase (GCL), the rate-limiting enzyme of glutathione (GSH) de novo biosynthesis. Moreover, NO increases the synthesis of the antioxidant GSH by inducing the expression of the catalytic subunit of GCL (GCLC). Chelating intracellular "free" zinc abrogates the NO-mediated increase of GCLC and of cellular GSH levels. As a consequence, the NO-mediated protection against H(2)O(2)-induced toxicity is impaired. We also show that under proinflammatory conditions, both cellular NO synthesis and intracellular "free" zinc are required to maintain the cellular GSH levels. Using RNA interference and laser scanning microscopy, we found that the NO-induced expression of GCLC depends on the activation of the transcription factor Nrf2 but not on the activity of the "zinc-sensing" transcription factor MTF-1. These findings show that intracellular "free" zinc plays a signaling role in the protective activity of NO and could explain why maintenance of an adequate zinc status in the endothelium is important to protect from oxidative stress and the development of vascular disease.

Abstract
Oxidative stress is one of the main causes of vascular disease. This study aims to investigate the antioxidant activity exerted by zinc in primary rat endothelial cells (EC). Using a 24-h treatment with hydrogen peroxide as a model for oxidative stress, we found that zinc supplementation protects from peroxide-induced cell death via increasing the transcription of the catalytic subunit (heavy chain) of glutamate-cysteine ligase (GCLC) and the concentrations of glutathione (GSH). Conversely, zinc depletion significantly decreased the expression of GCLC and the cellular GSH levels, resulting in an increased susceptibility of EC to oxidative stress. Using confocal microscopy and the RNA silencing technique, we found that zinc upregulates the expression of GCLC by activating the transcription factor Nrf2. Surprisingly, the intracellular zinc sensor, metal-responsive transcription factor-1, is not involved in the zinc-induced expression of GCLC. The present study shows that zinc controls the redox state of EC by regulating the de novo synthesis of GSH. This molecular mechanism may contribute to the elaboration of new nutritional and/or pharmaceutical approaches for protecting the endothelium against oxidative stress.

Abstract
Zinc bioinorganic chemistry has emphasized the role of the metal ion on the structure and function of the protein. There is, more recently, an increasing appreciation of the role of zinc proteins in a variety of human diseases. This critical review, aimed at both bioinorganic and medicinal chemists, shows how apparently widely-diverging diseases share the common mechanistic approaches of targeting the essential function of the metal ion to inhibit activity. Protein structure and function is briefly summarized in the context of its clinical relevance. The status of current and potential inhibitors is discussed along with the prospects for future developments (162 references).

Abstract
8-Benzenesulfonyloxy-5- N,N-dimethylaminosulfonylquinolin-2-ylmethyl-pendant cyclen (BS-caged-L(4), BS = benzenesulfonyl) was designed and synthesized as a "caged" derivative of a previously described Zn(2+) fluorophore, 8-hydroxy-5- N,N-dimethylaminosulfonylquinolin-2-ylmethyl-pendant cyclen (L(4)) (cyclen = 1,4,7,10-tetraazacyclododecane). In the absence of metal ions and in the dark, BS-caged-L(4) (10 microM) showed negligible fluorescence emission at pH 7.4 (10 mM HEPES with I = 0.1 (NaNO3)) and 25 degrees C (excitation at 328 nm). Addition of Zn(2+) induced an increase in the UV/vis absorption of BS-caged-L(4) (10 microM) at 258 nm and a significant increase in fluorescence emission at 512 nm. These responses are results from the formation of Zn(H-1L(4)) by the hydrolysis of the sulfonyl ester at the 8-position of the quinoline unit promoted by the Zn(2+)-bound HO(-). Improvement of cell membrane permeation in comparison with L(4) is also described.

Abstract
A water-soluble fluorescent zinc sensor which binds strongly to Zn2+ (log K = 12.4) was successfully synthesized under physiological conditions. This sensor exhibits a good fluorescence response to Zn2+ over a wide pH range in water. Under the same conditions, several metal ions commonly present in a physiological environment, such as Na+, K+, Ca2+, Mg2+, Mn2+, Fe2+, and Co2+, showed little interference to the fluorescence response to Zn2+.

Abstract
A new fluorescent probe for Zn2+, namely, 8-hydroxy-5-N,N-dimethylaminosulfonylquinolin-2-ylmethyl-pendant cyclen (L8), was designed and synthesized (cyclen=1,4,7,10-tetraazacyclododecane). By potentiometric pH, 1H NMR, and UV spectroscopic titrations, the deprotonation constants pKa1-pKa6 of L(8)4 HCl were determined to be <2, <2, <2 (for amino groups of the cyclen and quinoline moieties), 7.19+/-0.05 (for 8-OH of the quinoline moiety), 10.10+/-0.05, and 11.49+/-0.05, respectively, at 25 degrees C with I=0.1 (NaNO3). The results of 1H NMR, potentiometric pH, and UV titrations, as well as single-crystal X-ray diffraction analysis, showed that L8 and Zn2+ form a 1:1 complex [Zn(H-1L8)], in which the 8-OH group of the quinoline ring of L8 is deprotonated and coordinates to Zn2+, in aqueous solution at neutral pH. On addition of one equivalent of Zn2+ and Cd2+, the fluorescence emission of L8 (5 microM) at 512 nm in aqueous solution at pH 7.4 [10 mM HEPES with I=0.1 (NaNO3)] and 25 degrees C increased by factors of 17 and 43, respectively. We found that the cyclen moiety has the unique property of quenching the fluorescence emission of the quinolinol moiety when not complexed with metal cations, but enhancing emission when complexed with Zn2+ or Cd2+. In addition, the Zn2+-L8 complex [Zn(H-1L8)] is much more thermodynamically and kinetically stable (Kd{Zn(H-1L8)}=[Zn2+]free[L8]free/[Zn(H-1L8)]=8 fM at pH 7.4) than the Zn2+ complexes of our previous Zn2+ fluorophores ([Zn(H-1L2)] and [Zn(L3)]). Furthermore, formation of [Zn(H-1L8)] is much faster than those of [Zn(H-1L2)] and [Zn(L3)]. The staining of early-stage apoptotic cells with L8 is also described.
