A new series of phthalazine derivatives was synthesized from the reaction of 1-chloro-4-(4-phenoxyphenyl)phthalazine as a reactive starting material with different carbon, nitrogen, oxygen, and sulfur nucleophiles. The structural formulae of all products were confirmed and characterized by elemental analyses and spectral data (IR, H-1 NMR, C-13 NMR, and mass spectra). Some of the synthesized derivatives were screened for their antitumor activity against four human tumor cell lines using MTT assay. In comparison with doxorubicin as standard drug, compounds 1, 20, and 25 showed the most potent cytotoxic effect. In addition, investigation of antioxidant activity revealed that hydrazinylphthalazine 20 has the highest activity.

In this work, O-sulfonated poly(vinylpyrrolidonium) hydrogen sulfate ([PVP-SO3H]HSO4) has been prepared as a powerful recyclable solid acid catalyst and characterized using a variety of techniques including elemental analysis, FT-IR, TGA, SEM, XRD, pH analysis and Hammett acidity function. After preparation and identification the mentioned solid acid with wide acidic functional group sites, is utilized as a highly efficient catalyst for the synthesis of tetrahydrobenzimidazo[2,1-b]quinazolin-1(2H)-ones, 1-(benzothiazolylamino)phenylmethyl-2-naphthols and 2H-indazolo[2,1-b] phthalazine-1,6,11(13H)-triones in the absence of solvent. These eco-friendly protocols offer some advantages such as green and cost-effective procedures with excellent yields, shorter reaction times, simpler work-up, recovery, and reusability of a metal-free solid acid heterogeneous catalyst.

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 524-95-8 is helpful to your research. Category: phthalazines.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 66-99-9, Name is 2-Naphthaldehyde, molecular formula is C11H8O, belongs to phthalazine compound. In a document, author is Berber, Nurcan, introduce the new discover, Formula: https://www.ambeed.com/products/66-99-9.html.

A new series of phthalazine substituted urea and thiourea derivatives were synthesized, and their inhibitory effects on the activity of purified human carbonic anhydrases (hCAs I and II) were evaluated. 2H-Indazolo[2,1-b]phthalazine-trione derivative (1) was prepared with 4-nitrobenzaldehyde, dimedone, and phthalhydrazide in the presence of TFA in DMF, and nitro group was reduced to amine derivative (2) with SnCl2 center dot 2H(2)O. The compound was reacted with isocyanates and isothiocyanates to get the final products (3a-p). The results showed that all the synthesized compounds inhibited the CA isoenzymes activity. 3a (IC50 = 6.40 mu M for hCA I and 6.13 mu M for hCA II) has the most inhibitory effect. The synthesized compounds are very bulky to be able to bind near the zinc ion, and they much more probably bind as the coumarin derivatives.

In a document, author is Zivkovic, Marija D..

H-1 NMR spectroscopy was applied to study the catalytic activity of dinuclear Pd(II)-aqua complexes with different benzodiazine bridging ligands, [{Pd(en)(H2O)}(2)(mu-qx)](4+)(Pd1), [{Pd(en)(H2O)}(2)(mu-qz)](4+)(Pd2) and [{Pd(en)(H2O)}(2)(mu-phtz)](4+)(Pd3) (qx, qz and phtz denote quinoxaline, quinazoline and phthalazine, respectively), in the hydrolytic cleavage of the amide bond inN-acetylated L-methionylglycine (Ac-L-Met-Gly) and L-histidylglycine (Ac-L-His-Gly) dipeptides. All reactions were investigated with an equimolar amount of the reactants at pH = 2.0-2.5 in D2O and at 37 degrees C. The obtained data for the catalytic activity ofPd1-Pd3complexes are compared with those previously reported for [{Pt(en)(H2O)}(2)(mu-L)](4+)(L denotes benzodiazine: qx, qz and phtz), [{Pd(en)(H2O)}(2)(mu-L)](4+)and [{Pt(en)(H2O)}(2)(mu-L)](4+)(L denotes diazine: pyrazine and pyridazine) complexes. It was found that catalytic activity of these complexes in peptide cleavage is strongly related to the position of the nitrogen atoms in the benzodiazine or diazine bridging ligand. The investigated dinuclear Pd(II) and Pt(II) complexes show catalytic activity in the selective hydrolysis of the Met-Gly amide bond of Ac-L-Met-Gly dipeptide. Moreover, all the above mentioned Pd(II) complexes were also able to catalyze the regioselective hydrolysis of the His-Gly amide bond of Ac-L-His-Gly dipeptide. However, in the reaction with Ac-L-His-Gly, only Pt(II) aqua complexes containing bridging ligands with two nitrogen atoms in thepara-position (quinoxaline and pyrazine) were able to cleave this dipeptide.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1008-72-6, in my other articles.

In a document, author is Amirmahani, Najmeh, introduce the new discover.

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

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 36809-26-4. Quality Control of (4-Bromophenyl)diphenylamine.

A new, convenient, and efficient method for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones is developed starting from phthalhydrazide, aromatic aldehydes, and malononitrile using 4-N, N-dimethylaminopyridin as catalyst. This modified route provides much higher yields and a simple work-up procedure of products. Also this methodology is of interest due to the use of ethanol as a solvent without use of any toxic metals as catalyst, thus minimizing the cost, the operational hazards, and environmental pollution.
