Organo-Sulfonic acid tags anchored on magnetic titana coated NiFe2O4 nanoparticles (nano-NiFe2O4@TiO2-SiO2-Pr-DEA-OSO3H) was prepared and characterized by various analysis methods including Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), vibrating sample magnetometer (VSM), X-ray diffraction (XRD) and thermo gravimetric analysis (TGA). These modified nanoparticles were used as efficient and recoverable hybrid nanocatalyst in multicomponent synthesis of some phthalazine-trione and benzo[4,5]imidazo[1,2-a]pyrimidine derivatives under green conditions. High yields within shorter reaction times, simple purification, and environmentally mild reaction conditions are some advantages of this protocol.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 92-92-2. Safety of [1,1′-Biphenyl]-4-carboxylic acid.

With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation for quality and ethical publishing we’ve spent the past two centuries establishing. 92-92-2, Name is [1,1′-Biphenyl]-4-carboxylic acid, SMILES is O=C(C1=CC=C(C2=CC=CC=C2)C=C1)O, in an article , author is Ramezani, Mahin, once mentioned of 92-92-2, Category: phthalazines.

In this paper we investigated reactions of urazole and phthalazine with N-(aryl)-2,2,2-trifluoroacetimidoyl chloride derivatives. Results showed that when imidoyl chloride derivative has a fluorine atom at ortho position (3a-c), in two steps under a S(N)i mechanism and then SNAr reaction mechanism produce ay1-5-(trifluoromethyl)-1H-benzo [el [1,2,4]triazolo[1,2-a] [1,2,4]triazine-1,3(2H)-diones (4a-c) and 6-(trifluoromethyl)benzo[5,6][1,2,4]triazino[1,2-b]phthalazine-8,13-diones (4i,4j) in good to excellent yields. In the other imidoyl derivatives (3d-h and 3i,3j) under these conditions cyclization reaction does not occur and therefore produce 1-aryl-2,2,2-trifluorornethyl)-4-phenyl-1,2,4-triazolidine-3,5-diones (4d-h) and 2-(2,2,2-trifluoro-1-(arylimino)ethyl)-2,3-dihydrophthalazine-1,4-diones(4k,41) (non-cyclic products) in good to excellent yields.

A series of mononuclear gold(iii) complexes of the general formula [AuCl3(diazanaphthalene)], where diazanaphthalene is quinazoline (qz, 1), phthalazine (phtz, 2), 1,5-naphthyridine (1,5-naph, 3), 1,6-naphthyridine (1,6-naph, 4) or 1,8-naphthyridine (1,8-naph, 5), were prepared and fully characterized. The complexes 1-5 consist of discrete monomeric species with the Au(iii) cation in a square planar coordination geometry surrounded by three chloride anions and one diazanaphthalene ligand. Crystallographic studies indicate the presence of an extended 4 + 1 or 4 + 2 geometry around the square planar [AuCl3(diazanaphthalene)] center due to AuMIDLINE HORIZONTAL ELLIPSISCl and AuMIDLINE HORIZONTAL ELLIPSISN interactions. The crystal structures of these complexes are controlled by a variety of intermolecular interactions that utilize the amphiphilic properties of the coordinated chloride anions and involve C-H groups, pi-electrons, and an uncoordinated nitrogen atom of the diazanaphthalene ligand. The usual offset pi-stacking between the N-heteroaromatic ligands appears to be completely hindered between the 1,5-naph fragments and significantly weakened between the 1,6-naph and 1,8-naph in their respective complexes 3, 4 and 5, for which the average molecular polarizability (alpha) values are the lowest in the series. It is remarkable that the [AuCl3(benzodiazine)] complexes 1 and 2 form centrosymmetric crystals, but the [AuCl3(naphthyridine)] complexes 3-5 assemble into non-centrosymmetric aggregates, making them potential alternatives to the previously studied systems for application in various fields by taking advantage of their polarity.

The cynomolgus macaque is a non-human primate species widely used in drug metabolism studies. Despite the importance of genetic polymorphisms in cytosolic aldehyde oxidase (AOX) 1 in humans, genetic variants have not been investigated in cynomolgus or rhesus macaques. Genetic variants in AOX1 were identified and allele frequencies were assessed using the genomes of 24 cynomolgus and 8 rhesus macaques. The analysis identified 38 non-synonymous variants, some of which were unique to cynomolgus macaques (bred in Cambodia, Indochina, or Indonesia) or rhesus macaques, whereas many variants were shared by the two lineages. Among the variants observed at relatively high frequencies, eight were selected for functional analysis. Recombinant P605L and V1338I AOX1 variants showed substantially lower phthalazine and carbazeran oxidation activities than the wild-type AOX1 protein. In liver cytosolic fractions from cynomolgus and rhesus macaques genotyped for P605L and V1338I AOX1, groups of cytosolic fractions with P605L and/or V1338I AOX1 variants showed significantly lower phthalazine and carbazeran oxidation activities than the wild type. These results indicate that AOX1 is polymorphic in cynomolgus and rhesus macaques, just as it is in humans. Further investigation is needed to reveal the functional significance of these AOX1 variants in drug metabolism.

A series of luminogens comprising one pyridine, 1,3-diazine, 1,4-diazine, 1,2-diazine and phthalazine moiety as the central core and two AIE-active tetraphenylethene units in lateral positions have been readily synthesized by Suzuki cross-coupling. They exhibited remarkably different photophysical and electrochemical properties, as well as solid packing and fine controllability via the number and position of the nitrogen atoms in the aromatic azaheterocycle core. Among them, the pyridine, 1,3-diazine and 1,4-diazine-cored luminogens displayed strong AIE activities, whereas the 1,2-diazine and phthalazine-cored luminogens exhibited almost no AIE effect. The intrinsic Lewis basicity of the as-prepared luminogens endowed them with the ability to fluorometrically detect acids with different pK(a) values. When protonated by a strong acid such as trifluoroacetic acid, the pyridine, 1,3-diazine and 1,4-diazine-cored luminogens displayed relatively weak AIE effects. In contrast, the 1,2-diazine and phthalazine-cored luminogens exhibited highly sensitive responses to strong acids within a precise pKa range by displaying turn-on fluorescence emissions in the low-energy region, which was probably owing to the synergetic effect of AIE and the constraint of the intersystem crossing effect upon protonation of the 1,2-diazine segment. They displayed reversible acidochromism in response to protonation and deprotonation in the solid state. Such unique properties of the as-prepared luminogens could be used for the selective discrimination of some organic acids, which is highly valuable in the study of biological metabolism.

The rapid and environmental synthetic route to produce 1H-indazolo[1,2-b] phthalazine-1,6,11-triones and 1H-pyrazolo[1,2-b]phthalazine-5,10-diones derivatives have been developed via multicomponent and one-pot reactions of various aldehydes, cyclic or acyclic 1,3-diketones with: i) phthalhydrazide or ii) phthalic anhydride-hydrazinium hydroxide using wet 2,4,6-trichlorotriazine (TCT) as catalyst under solvent-free conditions. Simple and mild reaction conditions, the use of a cheap catalyst and easy workup and isolation are notable features of this method.

Aldehyde oxidase (AOX) is a cytosolic enzyme expressed across a wide range of species, including guinea pig and rhesus monkey. These species are believed to be the best preclinical models for studying human AOX-mediated metabolism. We compared AOX activity in rhesus monkeys, guinea pigs, and humans using phthalazine and N-[2-(dimethylamino) ethyl] acridone-4-carboxamide (DACA) as substrates and raloxifene as an inhibitor. Michaelis-Menten kinetics was observed for phthalazine oxidation in rhesus monkey, guinea pig, and human liver cytosol, whereas substrate inhibition was seen with DACA oxidase activity in all three livers. Raloxifene inhibited phthalazine and DACA oxidase activity uncompetitively in guinea pig, whereas mixed-mode inhibition was seen in rhesus monkey. Our analysis of the primary sequence alignment of rhesus monkey, guinea pig, and human aldehyde oxidase isoform 1 (AOX1) along with homology modeling has led to the identification of several amino acid residue differences within the active site and substrate entrance channel of AOX1. We speculate that some of these residues might be responsible for the differences observed in activity. Overall, our data indicate that rhesus monkeys and guinea pigs would overestimate intrinsic clearance in humans and would be unsuitable to use as animal models. Our study also showed that AOX metabolism in species is substrate-dependent and no single animal model can be reliably used to predict every drug response in humans.

Two protocols for oxygenation of aromatic C-H bonds ortho-positioned to the phthalazine ring were developed. The transannulation of the phthalazine ring to a naphthalene moiety by an Inverse Electron Demand Diels-Alder (IEDDA) reaction led to the synthesis of naphtho[2,1-c]chromenes, 1-(ortho-hydroxyaryl)naphthalenes and 6,7-dihydrobenzo[b]naphtho[1,2-d]oxepine. This new strategy based on the utilization of transformable nitrogen heterocycles in C-H functionalization chemistry can be potentially applicable to the synthesis of a broad range of biaryl compounds.
