UHPLC-fluorescence method for the determination of trace levels of hydrazine in allopurinol and its formulations: Validation using total-error concept

The present approach poses an interesting way to quantify residues of the genotoxic impurity hydrazine in allopurinol and its pharmaceutical formulations using ultra high performance liquid chromatography coupled to fluorescence detection. Hydrazine was pre-column derivatized through a unique chemistry with o-phthalaldehyde under acidic conditions. Using highly acidic mobile phase the derivative exhibits a strong fluorescence intensity. Derivatization and chromatographic parameters were thoroughly investigated. The validation of the developed method has been carried out in the range of 10 to 200% of the target concentration limit of the analyte using the accuracy profiles as a graphical decision-making tool. The beta-expectation tolerance intervals did not exceed the acceptance criteria of ¡À20% which means that 95% of future results will be included in the defined bias limits. The variation of the relative bias ranged between ?6.0 and 0.5% and the RSD values for repeatability and intermediate precision were lower than 6.9% in all cases. The limit of detection (LOD) and the lower limit of quantification (LLOQ) were satisfactory and found to be 0.3 ng mL?1 (corresponding to 0.03 mug g?1 in solid sample). Experimental designs were constructed to study the robustness of the instrumental method and the derivatization procedure. The developed method has been successfully applied for the analysis of hydrazine in allopurinol API batches and tablets indicating that this methodology could be adopted from QC laboratories.

The one-pot synthesis of homoleptic phenylphthalazine iridium(III) complexes and their application in high efficiency OLEDs

A series of homoleptic cyclometalated iridium (III) complexes bearing a 1-phenylphthalazine framework have been synthesized with a facile one-pot method and characterized by X-ray single crystal diffraction. All complexes exhibited orange or red emission peaks at 583?623 nm with short lifetimes of 1.3?2.6 mus and high photoluminescence quantum yields of 41%?82%. These complexes exhibit good thermal stability with high Td of 275?394 C. The electronic states and orbital distributions of these iridium (III) complexes were studied by density functional theory. These complexes were used as emissive materials in Organic light-emitting diodes (OLEDs). The device based on 2 gave a peak current efficiency and external quantum efficiency (EQE) of 35.1 cd A?1 and 21.2%, respectively. The color coordinates of device based on 3 fully meet that of standard red of the National Television Standards Committee (NTSC). These results suggest that homoleptic phenylphthalazine iridium (III) complexes have potential application as efficient emitters in OLEDs.

Luminescent hydrido-carbonyl clusters of rhenium containing bridging 1,2-diazine ligands

The reaction of the electronically unsaturated (56 valence electrons, ve) tetrahedral cluster [Re4(mu3-H)4(CO) 12] (1) with pyridazine (pydz) gives as the main initial product the tetranuclear cluster [Re4(mu-H)4(mu-pydz)(pydz) 2(CO)12] (2a), with 64 ve and four hydrogen-bridged metal-metal interactions, with a spiked-triangle geometry. One of the three pydz ligands bridges, in a cis configuration, the cluster edge opposite to the vertex bearing the spike, as indicated by the X-ray single-crystal analysis. This species slowly decomposes, affording the dinuclear unsaturated (32 ve) complex [Re2(mu-H)2(mu-pydz)(CO)6] (3a) and two isomers of the tetranuclear cluster [Re4(mu-H) 4(mu-pydz)2-(CO)12] (64 ve), sharing an unusual square cluster geometry and differing in the trans (major, 85%, 4a) or cis (4a?) configuration of the bridging pydz ligands. The structures of 3a and 4a have been ascertained by X-ray analysis, while the characterization of 4a? was hampered by its instability (slowly transforming into 3a in THF solution). Both the dimer and the square cluster 4a are also formed directly (and quickly) from 1, being present in solution since the beginning of the reaction. Cluster 4a is the main final reaction product. The reaction with phthalazine follows a similar course, with some differences in the relative amount of the final products 3b and 4b. Most of the novel complexes are able to emit light in solution at room temperature, and photophysical measurements were performed in CH2Cl2 solution on the main stable reaction products (i.e., the dinuclear species 3a and 3b and the trans square clusters 4a and 4b). The emission was in the range of 580-645 nm, from MLCT excited states, with lifetimes on the order of a hundred nanoseconds (50-473 ns). The quantum yields were 1 order of magnitude higher for the squares (1.7 and 1.3% for 4a and 4b, respectively, in CH2Cl2) than for the dinuclear complexes (?0.1%). In the case of 4a, a blue shift and an increase of the emission intensity were observed upon decreasing the solvent polarity.

Structural basis for the role of mammalian aldehyde oxidases in the metabolism of drugs and xenobiotics

Aldehyde oxidases (AOXs) are molybdo-flavoenzymes characterized by broad substrate specificity, oxidizing aromatic/aliphatic aldehydes into the corresponding carboxylic acids and hydroxylating various heteroaromatic rings. Mammals are characterized by a complement of species-specific AOX isoenzymes, that varies from one in humans (AOX1) to four in rodents (AOX1, AOX2, AOX3 and AOX4). The physiological function of mammalian AOX isoenzymes is unknown, although human AOX1 is an emerging enzyme in phase-I drug metabolism. Indeed, the number of therapeutic molecules under development which act as AOX substrates is increasing. The recent crystallization and structure determination of human AOX1 as well as mouse AOX3 has brought new insights into the mechanisms underlying substrate/inhibitor binding as well as the catalytic activity of this class of enzymes.

One-step exchange-labelling of pyridines and other N-heteroaromatics using deuterium gas: catalysis by heterogeneous rhodium and ruthenium catalysts

A wide range of pyridines and other nitrogen heteroaromatics can be labelled with deuterium at room temperature and pressure by isotopic exchange with deuterium gas in THF in the presence of rhodium black, ruthenium black or 5% rhodium on alumina. The labelling is rapid, isotope efficient and applicable to both electron-rich and electron-poor substrates. In a few cases, a degree of reduction accompanies the exchange.

Small-molecule luminescent probes for the detection of cellular oxidizing and nitrating species

Reactive oxygen species (ROS) have been implicated in both pathogenic cellular damage events and physiological cellular redox signaling and regulation. To unravel the biological role of ROS, it is very important to be able to detect and identify the species involved. In this review, we introduce the reader to the methods of detection of ROS using luminescent (fluorescent, chemiluminescent, and bioluminescent) probes and discuss typical limitations of those probes. We review the most widely used probes, state-of-the-art assays, and the new, promising approaches for rigorous detection and identification of superoxide radical anion, hydrogen peroxide, and peroxynitrite. The combination of real-time monitoring of the dynamics of ROS in cells and the identification of the specific products formed from the probes will reveal the role of specific types of ROS in cellular function and dysfunction. Understanding the molecular mechanisms involving ROS may help with the development of new therapeutics for several diseases involving dysregulated cellular redox status.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3682-14-2, help many people in the next few years.name: 6-Amino-2,3-dihydrophthalazine-1,4-dione

Olefin poly/oligomerizations by metal precatalysts bearing non?heterocyclic N?donor ligands

The use of transition metal complexes of non?heterocyclic N?donor ligands as olefin oligo/polymerization precatalysts is reviewed. These metal complexes with definite steric and electronic variations offer high catalytic activity resulting in the desired microstructure of the polymer products currently attracting significant attention by the catalysis community. This review primarily discusses the fundamental principles in the design of mononuclear, homodinuclear, heterodinuclear, homomultinuclear and heteromultinuclear transition metal complexes having non?heterocyclic N?donor ligands and their reactivity towards olefins in oligo/polymerization reactions. Numerous non?heterocyclic N?donor ligands of the donor types N2, NO, NP, NC, N2P, N2O, N2C, N2S, N3, NCP, NCp, NOCp, N3Cp, N2O2for mononuclear, N4, N2O2, N4O4, N3C, NCp2, N2Cp2, N2Indene2and N2S2Indene (Cp: cyclopentadiene) for bimetallic and N8, N8O4, N8O8and N12O4for multinuclear complex formations have been efficiently employed, and the resulting complexes display promising reactivity patterns with a variety of olefins. The majority of these catalytic systems are tethered with appropriate alkyl/aryl/alkyl?aryl substituents to afford the required steric hindrance to the metal center(s), and with functional groups for electronic variations. Such systems produce a linear polymer product in most of the cases, any deviation from this behavior resulting in the formation of oligomers. The major focus of this review is on reports published over the last 25 years in the research and development of non?heterocyclic, N?donor coordinated transition metal complexes with a variety of spacers. This review article is organized into main sections on the basis of the nuclearity of the transition metal complex; each subsection deals with complexes starting from late transition metals on the basis of ligand type.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 253-52-1 is helpful to your research. Electric Literature of 253-52-1
