We report an air-stable bisboron complex as an efficient catalyst for the inverse electron-demand Diels-Alder (IEDDA) reaction of 1,2-diazine as well as 1,2,4,5-tetrazine. Its stability towards air and moisture was demonstrated by NMR studies enabling its application in organic transformations without glovebox. A one-pot procedure for its synthesis was developed starting from 1,2-bis(trimethylsilyl) benzene greatly enhancing its practicality. Comparative reactions were carried out to evaluate its catalytic activity in IEDDA reactions of diazine including phthalazine as well as 1,2,4,5-tetrazine.

MnFe2O4@SiO2@NHPhNH2-phosphotungstic acid was synthesized by the reaction of diamine-modified silica coated manganese ferrite nanoparticles with H3PW12O40, the Keggin-type heteropoly acid. This is the first time that H3PW12O40 supported on diamine functionalized MnFe2O4 nanoparticles has been reported. The synthesized catalyst was characterized by various techniques, including Fourier Transform Infrared Spectroscopy (FTIR), Transmission electron-microscopy (TEM), X-ray Powder Diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDX), Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), Thermogravimetric Analysis (TGA), and Vibrating Sample Magnetometer (VSM). The synthesized nanoparticle was examined as the heterogenous nanocatalyst for the synthesis of tetrahydrobenzo[b]-pyran derivatives and 2H-indazolo-[2,1-b]-phthalazine-triones under the solvent-free heating or ultrasonic irradiation conditions. This method offers several advantages including high yield, low reaction times, and the simple work up procedure due to the presence of the magnetic nanoparticles in this catalyst, so that, it can be easily recovered and reused for at least six successive times without the loss of its high catalytic activity, suggesting its great Potential for industrial applications.

Binuclear complexes of copper(II) with 1′-phthalazinylhydrazones of substituted salicylic aldehydes have been prepared and studied. Antiferromagnetic exchange interaction between copper(II) ions has been revealed in all the complexes. Taking advantage of quantum-chemical simulation, we have investigated the influence of the complexes structural isomerism on the character of the exchange interaction between the paramagnetic centers. X-ray absorbance spectroscopy afforded the structural parameters of coordination spheres of copper(II) ions; it has been demonstrated that dimerization occurred via the nitrogen atoms of phthalazine fragments.

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. 620-14-4, Name is 3-Ethyltoluene, SMILES is CC1=CC(CC)=CC=C1, in an article , author is Boulebd, Houssem, once mentioned of 620-14-4, Formula: https://www.ambeed.com/products/620-14-4.html.

Hydralazine (HZ) and dihydralazine (DHZ) are phthalazine derivatives substituted at position 1 (HZ) or positions 1 and 4 (DHZ) by a hydrazinyl substituent. These compounds are widely used for treating hypertension and heart failure, essentially acting as vasodilators on the arteries and arterioles. In this study, the antioxidant activity of HZ and DHZ in the gas phase and in physiological environments was investigated by thermodynamic and kinetic calculations. It was found that the HOO center dot radical scavenging activity of these compounds follows the formal hydrogen transfer (FHT) mechanism. The H abstraction of the N9-H bond plays a deciding role in the HOO center dot radical scavenging of HZ-1 and DHZ-I, whereas the HOO center dot radical scavenging activities of HZ-2 and DHZ-2 are defined by the dissociation of the N10-H and Nil-H bonds, respectively. The rate constants for the HOO center dot radical scavenging of the HZ and DHZ in the gas phase are in the range of 9.64 x 10(6) to 4.52 x 10(8) M-1 s(-1), whereas in aqueous solutions and the lipid medium they are in the range of 2.62 X 10(4) to 5.13 x 10(7) M-1 s(-1) and 5.75 x 10(4) to 6.66 x 10(6) M-1 s(-1), respectively. The HOO center dot radical scavenging of DHZ-1 and DHZ-2 is thus faster than that of the reference antioxidant compound Trolox in all the studied environments. Consistently, DHZs are not only vasodilators but also potent antioxidants.

New silver.I) complexes with quinazoline (qz) and phthalazine (phtz), [Ag(NO3)(qz)](n) (1) and {[Ag(CH3CN)](2)(mu-phtz)(2)}[BF4](2) (2), have been synthesized and structurally characterized by using different spectroscopic and single-crystal X-ray diffraction techniques. The obtained results revealed that the reaction of AgNO3 with qz at room temperature in a 2 : 1 molar ratio led to the formation of the polynuclear complex 1. However, the reaction of AgBF4 with phtz under the same experimental conditions resulted in the formation of the dinuclear complex 2. The solution behaviour and air/light stability of these silver.I) complexes have been investigated. The complexes 1 and 2, along with the silver.I) salts used for their synthesis, were evaluated by in vitro antimicrobial studies against a panel of microbial strains that lead to many skin and soft tissue, respiratory, wound, and nosocomial infections. The obtained results indicate that all tested silver(I) compounds have good antibacterial activity with MIC values in the range from 1.5 to 15.6 mu g mL(-1) against the investigated strains. On the other hand, their antifungal activity against Candida albicans was moderate. In order to determine the therapeutic potential of 1 and 2, their antiproliferative effect on the normal human lung fibroblast cell line MRC5, hemolytic effect on red blood cells and embryotoxicity on zebrafish (Danio rerio) have also been evaluated.

The transcription factor nuclear factor-kappa B (NF-kappa B) controls many physiological processes including inflammation, immunity, and apoptosis. In this study, a novel series of 6-phenoxy-[1,2,4] triazolo[3,4-a] phthalazine-3-carboxamide derivatives were synthesized as potent anti-inflammatory agents, which acted on tumor necrosis factor (TNF-alpha) as inhibitors of NF-kappa B activation. We showed that compounds 6h (6-(2,4-dichlorophenoxy)-[1,2,4] triazolo[3,4-a] phthalazine-3-carboxamide) and 6i (6-(3-tolyloxy)[1,2,4] triazolo[3,4-a]phthalazine-3-carboxamide) showed more prominent anti-inflammatory activity than other compounds, with similar activities as the reference drug dihydrotanshinone; compound 6i showed the lowest cellular toxicity among the tested compounds. In vivo evaluation of the anti-inflammatory activity showed that compound 6i exhibited excellent anti-inflammatory activity with 58.19% inhibition at 50 mg/kg intraperitoneal (i.p.), with equal efficacy as the positive control indomethacin (100 mg/kg i.p.; 59.21% inhibition).

In a article, author is Tayebee, Reza, introduce new discover of the category.

PbO nanoparticles were explored as a highly efficient, simple, cheap, and recyclable catalyst for the fast synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives by means of a one-pot three-component reaction of phthalhydrazide, aromatic aldehyde, and malononitrile under solvent-free conditions at 80 A degrees C. Furthermore, nanosized PbO was prepared by the two conventional methods of planetary ball milling and dispersion of commercial PbO in n-octane, and their catalytic performances were compared with the commercial bulk PbO. The prepared nano-PbO via ball milling was described by SEM, TEM, XRD, EDX, and FT-IR spectroscopy. The present protocol conveyed major proficiencies such as the use of a reasonable and readily available catalyst, simple work-up and purification of products by nonchromatographic strategy, low reaction times, and enhanced yields under relatively environmental benign conditions. The heterogeneous catalyst was appropriately recyclable and could be reused for several times without loss of activity.

Quantum theoretical calculations for the three structures of compounds (5a, 5b, and 5c) were performed using the G3MP2, LC-omega PBE, MP2, and B3LYP methods with the 6-311 + G** basis set. After optimizing the structures, geometric parameters were obtained and experimental measurements were compared with the calculated data. The structures of the products were confirmed by IR, H-1 NMR, C-13 NMR, and elemental analysis. IR spectra data and H-1 NMR and C-13 NMR chemical shifts computations of the 1H-indazolo[1,2-b]phthalazine-1,6,11(13H)-trione derivatives in the ground state were calculated. Frontier molecular orbitals, total density of states, thermodynamic parameters, and molecular electrostatic potentials of the title compounds were investigated by theoretical calculations.
