Abstract:
Vascular endothelial cells, smooth muscle cells, macrophages, neutrophils, Kupffer cells and other diverse cell types generate superoxide (O2.-) and nitric oxide (.NO), which can react to form the potent oxidant peroxynitrite anion (ONOO-). Peroxynitrite reacted with luminol to yield chemiluminescence which was greatly enhanced by bicarbonate. The quantum chemiluminescence yield of the ONOO- reaction with luminol in bicarbonate was approx. 10(-3). Chemiluminescence was superoxide dismutase-inhibitable, indicating that O2.- was a key intermediate for chemiexcitation. O2.- appears to be formed secondarily to the reaction of a bicarbonate-peroxynitrite complex with luminol, yielding luminol radical and O2.-. Luminol radical reacts with O2.- to form the unstable luminol endoperoxide, which follows the light-emitting pathway. Neither .NO nor O2.- alone were capable of directly inducing significant luminol chemiluminescence in our assay systems. These results suggest that ONOO- can be a critical unrecognized mediator of cell-derived luminol chemiluminescence reported in previous studies. In addition, it is shown that bicarbonate can participate in secondary oxidation reactions after reacting with ONOO-.

Abstract:
Common peroxidase action and haloperoxidase action are quantifiable as light emission from dioxygenation of luminol (5-amino-2,3-dihydrophthalazine-1,4-dione). The velocity of enzyme action is dependent on the concentration of reactants. Thus, the reaction order of each participant reactant in luminol luminescence was determined. Horseradish peroxidase (HRP)-catalyzed luminol luminescence is first order for hydrogen peroxide (H2O2), but myeloperoxidase (MPO) and eosinophil peroxidase (EPO) are second order for H2O2. For MPO, reaction is first order for chloride (Cl−) or bromide (Br−). For EPO, reaction is first order for Br−. HRP action has no halide requirement. For MPO and EPO, reaction is first order for luminol, but for HRP, reaction is greater than first order for luminol. Haloperoxidase-catalyzed luminol luminescence requires acidity, but HRP action requires alkalinity. Unlike the radical mechanism of common peroxidase, haloperoxidases (XPO) catalyze non-radical oxidation of halide to hypohalite. That reaction is second order for H2O2 is consistent with the non-enzymatic reaction of hypohalite with a second H2O2 to produce singlet molecular oxygen (1O2*) for luminol dioxygenation. Alternatively, luminol dehydrogenation by hypohalite followed by reaction with H2O2 yields dioxygenation consistent with the same reaction order. Haloperoxidase action, Cl−, and Br− are specifically quantifiable as luminol luminescence in an acidic milieu.

Full text
Abstract:
Addition of the polyene antibiotic amphotericin B or tissue culture medium to nondifferentiated HL-60 cells in the presence of luminol induces a chemiluminescence signal that reaches a peak value within a few seconds and decays exponentially in less than a minute. The kinetics of the signal and its modulation by superoxide dismutase, catalase, and horseradish peroxidase are consistent with a series of solution biochemical processes with a rate-determining step corresponding to the disproportionation of a luminal–superoxide complex. The effects of the enzymes demonstrate that superoxide is a precursor to the rate-determining intermediate and that both catalase and peroxide enhance a reaction that competes with the rate-limiting process.Key words: chemiluminescence, luminol, amphotericin B, superoxide, HL-60 cells.

Abstract:
Functional luminol derivative with cholesteryl substituted group has been designed and synthesized from the reaction of the corresponding precursor cholesteryl chloroformate with luminol. It has been found that depending on cholesteryl substituted group, the formed luminol derivative showed different properties, indicating distinct regulation of molecular skeleton. UV and IR data confirmed commonly the formation of imide group as well as cholesteryl segment in molecular structure. Thermal analysis showed that the thermal stability of luminol derivative with cholesteryl segment was different from luminol. The difference of thermal stability is mainly attributed to the formation of imide group and cholesteryl substituent group in molecular structure. The present results have demonstrated that the special properties of luminol derivative can be turned by modifying molecular structure of objective compound with proper substituted groups, which show potential application in functional material fields such as liquid crystal and ECL sensor.

Abstract:
The chemiluminescence (CL) emission spectra of luminol were recorded using Fuss spectrograph in different aqueous aliphatic amines using sodium persulphate alone and mixture with hydrogen peroxide as an oxidant. The CL emission spectra after resolution showed two emission bands at 425 and 455 nm. The CL mechanism was explained on the basis of two exited state species formed during oxidation of luminol. The CL of luminol is found to be very weak as persulphate slowly produced oxygen. The glow become intense with time as more and more oxygen is made available for oxidation of luminol. The mixture of hydrogen peroxide and sodium persulphate is found to be more effective in producing intense and long lived CL glow for luminol. The CL emission band of luminol by using sodium persulphate and mixture with hydrogen peroxide is explained on the basis of formation of exited singlet and triplet state of 3-aminophthalate ion (3-APA). The shorter wavelength emission band of 425 nm is found to be very weak in intensity as compared to longer wavelength emission band of 455 nm. Thus phosphoresce is favored in case of persulphate CL of luminol.

Abstract:
The interaction behavior of bovine serum albumin (BSA), lysozyme (LYS), myoglobin (MB), and catalase (CAT) with luminol, respectively, was first studied by chemiluminescence (CL) using flow injection (FI) technique based on the fact that the studied proteins can enhance the CL intensity of luminol. A FI-CL model of protein-luminol interaction, lg[(I0−I)/I]=1/nlg[P]+1/nlgKa+2lgn, was constructed, and the interaction parameters of BSA, LYS, MB, and CAT with luminol were determined accordingly. The binding constants Ka are in the descending order of CAT > MB > LYS > BSA at the level of 105 to 107 L mol−1, and the number of binding sites n of luminol to BSA or LYS is around 2 and to MB or CAT is around 1. The results of thermodynamic parameters (ΔH, ΔS, and ΔG) showed that the binding processes of luminol to the four proteins are spontaneous mainly through the hydrophobic force.

Abstract:
In a crime scene, the collection of evidence and a subsequent laboratory analysis compose the fundamental steps to allow the expert to reveal the truth for the final verdict in a jury and to bring back the comfort to the victim’s family. Bloodstains are usually found and sent to laboratories as a vestige to unravel the origin of the material. However, some scenes are modified in order to conceal the real culprit for the criminal act. For these cases, the luminol reagent can be useful. This test is very often used to visualize occult blood. Luminol is considered the most sensitive test once it can identify the blood presence in scale of nanograms. When this reagent comes into contact with blood,the light emission occurs through a phenomenon known as chemiluminescence. This luminescence can be produced by other interfering compounds, leading to a misinterpretation for the presence of blood. Despite this shortcoming, the present review article highlights the indispensability of the reagent luminol on a crime scene.

Abstract:
The luminol-hydrogen peroxide chemiluminescent system is widely used for the creation of diagnostic systems, for chemical analysis, for studying the kinetics and mechanisms of chemical reactions, for the creation of special and emergency light sources, and for monitoring living systems. However, the use of the luminol-hydrogen peroxide chemiluminescent system is limited by the fact that there are almost no ways of managing the reaction. The introduction of organized molecular systems into the luminol-hydrogen peroxide chemiluminescent system can create an additional channel for controlling chemiluminescent reactions. The luminol-hydrogen peroxide system was not previously studied in various classes of hydrocarbon and perfluorinated micellar solutions. This work was the first to study the effect of cationic, anionic and nonionic hydrocarbon surface-active substances (cetyltrimethylammonium bromide, sodium decyl sulfate, sodium dodecyl sulfate, triton X 100) and perfluorinated surface-active substances (FT-135 and FT-248) on the chemiluminescent systems luminol-hydrogen peroxide-potassium hexacyanoferrate(III) and luminol-hydrogen peroxide-copper(II) sulphate. The systems retain the ability to chemiluminescence in the presence of a surfactant. Cationic surfactants lower the intensity of chemiluminescence, and anionic surfactants increase the intensity of chemiluminescence. The introduction of a surfactant into the system allows increasing the range of dependence of the chemiluminescence intensity on the catalyst concentration. Kinetic curves of the growth and decay of chemiluminescence were measured in the systems. The rate constants of the chemiluminescence decay were measured in the framework of the first-order kinetics model.

Abstract:
Objective: This study aimed at discovering chemiluminescent analogues of luminol, predict their molecular binding to hemoglobin of bloodstains in household crime, and expound the mechanism of chemiluminescence of luminol. Materials and Methods: Similarity and clustering analyses of luminol analogues were conducted, and molecular docking was carried out using hemoglobin from Homo sapiens and four domestic organisms namely Gallus gallus, Drosophila melanogaster, Rattus norvegicus, and Canis familiaris. Results: The results showed the order of overall binding score as D. melanogaster > H. sapiens > C. familiaris > R. norvegicus > G. gallus. Seven compounds namely ZINC16958228, ZINC17023010, ZINC19915427, ZINC34928954, ZINC19915369, ZINC19915444, and ZINC82294978, were found to be consistently stable in binding with diverse hemoglobin and possibly have chemiluminescence than luminol in this in silico study. The interaction of human hemoglobin with luminol and its analogues, showed that amino acid residues His45, Lys61, Asn68, Val73, Met76, Pro77, Ala79, Ala82, Leu83, Pro95, Phe98, Lys99, Ser102, Ser133, Ala134, and Thr134, were possibly significant in the mechanism of action of presumptive test compounds. It was hypothesized that the improved mechanism of chemiluminescent for the identification of blood was based on peroxidase-like reaction, that produces nitric oxide which binds to hemoglobin (Hb) and inhibits Hb degradation without yielding fluorescent products. The compound 2,3-benzodioxine-1,4,5(6H)-trione was formed, which possibly emits light. Conclusion: This study provides novel insight on the luminol and its expanded mechanism for broader possible applications with careful development of new methodologies.

Abstract:
Functional luminol derivative with cholesteryl substituted group has been designed and synthesized from the reaction of the corresponding precursor cholesteryl chloroformate with luminol. This compound can be spread on water surface to form stable monolayer. It has been found that UV and IR spectra confirmed the characteristic aromatic segment, imide group and cholesteryl substituted group. In addition, the CD spectra also showed positive CD signals, which may be attributed to the chiral cholesteryl substituted groups. AFM investigation indicated some aggregated domains with the averaged height about 3.6  0.2 nm appeared. This suggested an organized structure of double molecules may be fabricated in the transferred LB films. The present results have demonstrated that the interfacial properties of luminol derivative can be modified by changing proper substituted groups of luminol, which show potential application in functional material fields such as ECL sensor.

Abstract:
Phorbol 12-myristate 13-acetate-induced luminol chemiluminescence in rat Kupffer cells was doubled by the addition of L-arginine and significantly (up to 70%) inhibited by NG-nitro-L-arginine and NG-monomethyl-L-arginine, competitive inhibitors of L-arginine-dependent nitric oxide (NO) formation. The release of superoxide anion (O2-) by NADPH oxidase was neither affected by L-arginine nor by the inhibitors. Only very slight luminol chemiluminescence was detectable in lipopolysaccharide-pretreated Kupffer cells, a condition in which significant amounts of NO were formed but no O2-. In a cell-free system, significant luminol chemiluminescence only occurred when both authentic NO and the O2-/H2O2- generating system xanthine/xanthine oxidase were present. The results indicate that luminol chemiluminescence in phorbol-ester-activated Kupffer cells largely depends on L-arginine metabolism by NO synthase, requiring the concurrent formation of NO and O2-/H2O2.

AbstractObjective:This study aimed to evaluate the presence of reactive oxygen species in laryngeal cancer tissue, using a luminol-amplified chemiluminescence method.Materials and methods:Fourteen patients with histopathologically diagnosed laryngeal squamous cell carcinoma were enrolled. Patients with recurrent tumours or a history of prior chemotherapy or radiotherapy were excluded. Tissue specimens were harvested both from the tumour itself and from the neighbouring, apparently normal mucosa (immediately after tumour removal). Tissue specimens were washed with ice-cold saline solution and processed immediately, without storage. The level of reactive oxygen species was measured quantitatively by a luminol-amplified chemiluminescence method.Results:The mean luminol-amplified chemiluminescence values for tumour and control tissue were 140.52 (standard error of the mean 40.21) and 121.36 (standard error of the mean 35.33) relative light units/mg tissue, respectively. Furthermore, mean tumour and control luminol chemiluminescence values were compared for stage one and two tumours versus stage three and four tumours. Both the tumour and the control luminol chemiluminescence values for the latter tumour group were significantly higher than those for the former tumour group.Conclusion:This study measured directly the levels of reactive oxygen species in samples of laryngeal cancer tissue and normal mucosa. Higher levels of reactive oxygen species were found in laryngeal cancer tissue, suggesting a relationship between reactive oxygen species and laryngeal cancer.

Abstract:
AbstractThe kosmotropic effect induced by ammonium sulfate (AS) at concentrations greater than approximately 2.8 M allows the marked intensification of chemiluminescence (CL) arising from a conventional luminol–hydrogen peroxide (H2O2)–horseradish peroxidase (HRP) reaction. Because of the kosmotropic effect, CL is intensified by at least three orders of magnitude than that from the conventional HRP-catalyzed luminol reaction with no AS; the linear relationship between the CL intensity and the HRP concentration is established over the range of 0.3 pM to several tens of pM. The novel CL intensification effect on the HRP-catalyzed luminol CL can be stably and reproducibly induced. Graphical abstract

Abstract:
O luminol é um teste presuntivo para detecção de manchas de sangue, muito sensível, efetivo e seletivo. O objetivo deste trabalho é avaliar a eficácia do luminol na detecção de sangue após o entintamento das paredes em um local onde ocorreu um homicídio. Os peritos se dirigiram para a casa do suspeito e com o uso de uma espátula metálica retiraram parte do revestimento da parede do quarto e após nova aplicação do luminol observaram a mancha branco-azulada, intensa e de duração típica de sangue latente. Os fragmentos retirados da parede foram enviados para o laboratório de DNA que confirmou tratar-se de sangue da vítima. A aplicação dessa técnica no caso em questão encontrando manchas de sangue sob a pintura ajudou a perícia a traçar a dinâmica do evento, ficando mais clara a posição da vítima quando foi alvejada com tiros pelo seu agressor além de ligar aquele local à vítima. O luminol não é capaz de detectar sangue que está sob a tinta da parede. A deteção do sangue latente somente ocorre quando a camada de tinta é retirada.
