[29] Enhanced chemiluminescent reactions catalyzed by horseradish peroxidase

Enhancement of light emission from the horseradish peroxidase-catalyzed oxidation of diacyl hydrazides on addition of 6-hydroxybenzothiazole or phenol derivatives forms the basis of rapid, specific, and sensitive chemiluminescent assays for peroxidase. The advantages and wide applicability of the technique have been demonstrated in a range of ligand-binding assays. Careful selection of chemiluminescent reagents, enhancer, their relative proportions and reaction conditions, and more detailed knowledge of the mechanism of enhancement should enable further improvements in sensitivity and the intensity or constancy of light emission.

Modulation of neutrophil extracellular trap and reactive oxygen species release by periodontal bacteria

Oral bacteria are the main trigger for the development of periodontitis, and some species are known to modulate neutrophil function. This study aimed to explore the release of neutrophil extracellular traps (NETs), associated antimicrobial proteins, and reactive oxygen species (ROS) in response to periodontal bacteria, as well as the underlying pathways. Isolated peripheral blood neutrophils were stimulated with 19 periodontal bacteria. NET and ROS release, as well as the expression of NET-bound antimicrobial proteins, elastase, myeloperoxidase, and cathepsin G, in response to these species was measured using fluorescence-based assays. NET and ROS release was monitored after the addition of NADP (NADPH) oxidase pathway modulators and inhibitors of Toll-like receptors (TLRs). Moreover, bacterial entrapment by NETs was visualized microscopically, and bacterial killing was assessed by bacterial culture. Certain microorganisms, e.g., Veillonella parvula and Streptococcus gordonii, stimulated higher levels of ROS and NET release than others. NETs were found to entrap, but not kill, all periodontal bacteria tested. NADPH oxidase pathway modulators decreased ROS production but not NET production in response to the bacteria. Interestingly, TLR inhibitors did not impact ROS and NET release. These data suggest that the variability in the neutrophil response toward different bacteria may contribute to the pathogenesis of periodontal diseases by mechanisms such as bacterial avoidance of host responses and activation of neutrophils. Moreover, our results indicate that bacterium-stimulated NET release may arise in part via NADPH oxidase-independent mechanisms. The role of TLR signaling in bacterium-induced ROS and NET release needs to be further elucidated.

Pharmacological intervention with oxidative burst in human neutrophils

In this study we investigated the effect of five therapeutically used drugs and four natural polyphenolic compounds on the mechanism of oxidative burst of human neutrophils concerning their participation in the generation of reactive oxygen species (ROS). The compounds investigated decreased the oxidative burst of whole blood in the rank order of potency: N-feruloylserotonin > quercetin > curcumin > arbutin > dithiaden > carvedilol. The generation of intracellular reactive oxygen species in isolated neutrophils decreased in the same rank order, while carvedilol was ineffective. Scavenging of extracellular oxygen radicals followed the rank order of potency: N-feruloylserotonin > curcumin > quercetin > dithiaden. Arbutin and carvedilol had no effect. All compounds tested increased the activity of caspase-3 in cell-free system indicating a positive effect on apoptosis of neutrophils. Activation of protein kinase C was significantly decreased by dithiaden, curcumin, quercetin and N-feruloylserotonin. Carvedilol, dithiaden, quercetin and arbutin reduced activated neutrophil myeloperoxidase release more significantly compared with their less pronounced effect on superoxide generation The presented results are indicative of pharmacological intervention with neutrophils in pathological processes. Of particular interest was the effect of natural compounds. Intracellular inhibition of oxidative burst in isolated neutrophils by the drugs tested and natural antioxidants has to be further analysed since ROS play an important role in immunological responses of neutrophils.

Automated assays for von Willebrand factor activity

von Willebrand factor (VWF) ristocetin cofactor activity (VWF:RCo) by platelet aggregometry has been considered the gold standard for evaluating the ability of VWF to bind platelets for over 40 years. Many automated systems no longer require platelets and rather rely on agglutination of latex particles. Automated methods of measuring VWF activity have improved performance characteristics and are performed on the same coagulation instruments used for routine testing via immunoturbidimetric methodology. Alternatively, a newer chemiluminescence assay system for measuring VWF activity demonstrates excellent performance characteristics. As these methods are becoming widely used, it is important to assess their performance in diagnosing and monitoring different types of von Willebrand disease. We review the automated methodologies and the published performance of these VWF assays. Advantages and limitations of these automated methods are discussed.

Chemiluminescent detection of enzymatically produced H2S

Hydrogen sulfide (H2S) has emerged as an important biological signaling molecule. To better understand the multifaceted biological roles of H2S, the development of selective and sensitive biocompatible assays for H2S is becoming increasingly important. Motivated by these challenges, our laboratory is developing new methods to further detect and monitor biological H2S. Here, we describe in detail our recent advances in the development and the use of chemiluminescence-based H2S sensors to assist other investigators with use of these chemical tools. We highlight the use of these tools use by displaying their selectivity and high sensitivity toward H2S and provide examples of assays we have developed to detect enzymatically produced H2S.

Isothiocyanatoluminol as a chemiluminescence labeling reagent for amino acids and proteins

Isothiocyanatoluminol (ITL) was successfully synthesized from the reaction between luminol and thiophosgene in the presence of triethylamine. The optimized conditions were extended for the preparation of isothiocyanatoisoluminol (ITIL) and phenyl isothiocyanate (PI). The chemiluminescence (CL) of ITL was comparable to luminol. ITL was used as a CL labeling reagent for amino acid and bovine serum albumin (BSA) in which the -NH2 terminus of amino acid residue present in BSA acts as the labeling site.

Determination of lipids and their oxidation products by IR spectrometry

We proposed a procedure for the IR spectrometric determination of lipid hydroperoxides in biological systems. The main bands in the IR absorption spectra of linoleic acid and its hydroperoxide were identified, and analytical bands suitable for the determination of both compounds in their mixtures were selected. It was demonstrated that tert-butyl hydroperoxide can be used as an external standard for determining fatty acid hydroperoxides. Using the external standard method (calibration curve) for tert-butyl hydroperoxides, we calculated the concentration of linoleic acid hydroperoxide in its mixture with linoleic acid; it agreed with the specified values. Using the developed procedure, we estimated the concentration of hydroperoxide groups in natural cardiolipin. The results were compared to those obtained by an independent method (activated chemiluminescence).

Chemiluminescence of luminol induced by dissolution of oxide-covered aluminum in alkaline aqueous solution

One-electron reduction of oxygen, hydrogen peroxide, potassium peroxodisulphate and potassium peroxodiphosphate was studied during the dissolution of oxide-covered aluminum in alkaline aqueous solution. The production of free oxidizing radicals was monitored by luminol chemiluminescence (CL). It was observed superoxide, hydroxyl, sulphate and phosphate radicals can be generated by the present method. In addition, luminol can be detected below nanomolar level, the linear logarithmic calibration range covering several orders of magnitude of concentration. The metallic aluminum and low-valent aluminum ions are the primary reductants of the system. The electron transfer to the solution is proposed to occur by tunneling through a thin insulating aluminum oxide film at the solid/electrolyte interface in moderately alkaline solutions with simultaneous dissolution of the forming oxide film. In a highly alkaline solution, it is more probable that the oxidation of aluminum species occurs in direct contact of the metallic aluminum with the aqueous solution. In the latter case, short-lived solvated low-valent aluminum ions, hydrogen atom and its deprotonated form, the hydrated electron, can exist as reducing mediators in the chemical reactions in the close vicinity of the dissolving solid/electrolyte interface. Luminol was also observed to exhibit CL under purely reducing conditions produced by a presently unknown excitation pathway.
