Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 83-53-4, Name is 1,4-Dibromonaphthalene, molecular formula is C10H6Br2, belongs to phthalazine compound. In a document, author is Rego, Yuri F., introduce the new discover, HPLC of Formula: https://www.ambeed.com/products/83-53-4.html.

Fourteen phthalazine-triones bearing different substituents at C-4 position were synthesized through multicomponent reactions (MCR) by using phthalhydrazide, dimedone and diferent aldehydes as starting materials, p-sulfonic acid calix[4]arene as catalyst and ethyl lactate as solvent under microwave irradiation. Compounds 7-16 were obtained in excellent to moderate yields (94-51%) in only 10 min of reaction using this methodology. The antiproliferative activity against cancer cells was disclosed, for the first time, for synthesized compounds. The capacity of all compounds to inhibit cancer cells growth was dependent on the histological origin of cells. Compound 20 was active against more than one strain. (C) 2016 The Authors.

The chemistry of phthalazine derivatives has been of increasing interest since many of these compounds have found many chemotherapeutic applications. So this study aims to synthesize a library of phthalazine derivatives and to investigate their anti-inflammatory and anti-proliferative activities. Sixteen new phthalazinone derivatives (2a-p) were synthesized and tested for their in vitro antiproliferative and in vivo anti-inflammatory activities. All the synthesized compounds were identified and characterized by IR, H-1 NMR, C-13 NMR spectroscopy, and MS. Two compounds, 2b and 2i, showed significant anti-inflammatory activity comparable with that of the standard drug etoricoxib in the carrageenan-induced rat paw edema model at 3 and 5h, respectively. Three compounds (2h, 2j, and 2g) showed moderate sensitivity toward the renal cancer cell line UO-31.

93-28-7, Name is Eugenol Acetate, molecular formula is C12H14O3, belongs to phthalazine compound, is a common compound. In a patnet, author is Dmitrienko, Anton, once mentioned the new application about 93-28-7, Quality Control of Eugenol Acetate.

The aluminum(I) compound NacNacAl (NacNac=[ArNC(Me)CHC(Me)NAr](-), Ar=2,6-iPr(2)C(6)H(3),1) shows diverse and substrate-controlled reactivity in reactions with N-heterocycles. 4-Dimethylaminopyridine (DMAP), a basic substrate in which the 4-position is blocked, induces rearrangement of NacNacAl by shifting a hydrogen atom from the methyl group of the NacNac backbone to the aluminum center. In contrast, C-H activation of the methyl group of 4-picoline takes place to produce a species with a reactive terminal methylene. Reaction of1with 3,5-lutidine results in the first example of an uncatalyzed, room-temperature cleavage of an sp(2)C-H bond (in the 4-position) by an Al(I)species. Another reactivity mode was observed for quinoline, which undergoes 2,2 ‘-coupling. Finally, the reaction of1with phthalazine produces the product of N-N bond cleavage.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 482-05-3, Name is [1,1′-Biphenyl]-2,2′-dicarboxylic acid, SMILES is O=C(C1=CC=CC=C1C2=CC=CC=C2C(O)=O)O, in an article , author is Davarpanah, Jamal, once mentioned of 482-05-3, Recommanded Product: 482-05-3.

In the present work, amorphous silica nanoparticles were synthesized from low-cost rice husk ash (RH-SiO2). The nanoparticles were later modified by an acidic ionic liquid containing double-charged diazoniabi-cyclo[2.2.2]octane chloride using sol-gel method (RH@[SiPrDABCO@BuSO3H]HSO4). The structural properties of this Bronsted solid acid were systematically investigated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermal gravimetric analysis-derivative thermogravimetric analysis (TGA-DTG), and Brunauer-Emmett-Teller (BET) measurements. The catalytic activity of this nanocomposite was successfully tested through the one-pot synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones via three-component couplings of phthalhydrazide, aromatic aldehydes, and malononitrile. The heterogeneous catalyst could be recovered easily and reused without significant loss of its catalytic activity.

A direct carbocyclization of 2-aryl-2,3-dihydrophthalazine-1,4-diones is achieved using isocyanates as carbonyl source via Ru(II)-catalyzed sequential ortho-amidation followed by intramolecular nucleophilic substitution, delivering substituted indazolo[1,2-b]phthalazine-triones in good-to-excellent yields. For ortho-substituted 2-aryl-2,3-dihydrophthalazine-1,4-diones, the corresponding amidated products were also isolated in excellent yields by modifying the reaction parameters. Application of isocyanates as carbonyl source, high functional group tolerance on the two coupling partners and diverse chemical transformation of the synthesized fused and functionalized phthalazinones are the key highlights of the work.

Tetrabutyl phosphonium sulfate ([TBP](2)SO4), as novel room-temperature ionic liquid (RTIL), was synthesized by a simple cost-effective method, characterized by H-1, C-13, P-31 NMR and FT-IR spectrophotometry. The newly prepared catalyst was used as an efficient catalyst in some four multicomponent reactions (4MCRs) e. g., to synthesis pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine. This green method has several advantages such as short reaction time, using simple methods to prepare catalysts and products, easy operation and high efficiency of products. In addition, the catalyst can be easily recovered and reused several times with reduced average activity. Graphic abstract
