Synthetic Route of 117-34-0, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 117-34-0, Name is 2,2-Diphenylacetic acid, SMILES is O=C(O)C(C1=CC=CC=C1)C2=CC=CC=C2, belongs to phthalazine compound. In a article, author is Mantu, Dorina, introduce new discover of the category.

The synthesis, structure, and in vitro anticancer activity of a new class of anticancer derivatives with dihydrobenzo[5,6]isoindolo[1,2-a]phthalazine and dihydrobenzo[f]pyridazino[6,1-a]isoindole skeletons are presented. The preparation is straight and efficient, involving two steps only: a N-alkylation of the pyridazine or phthalazine heterocycle, followed by a [3 + 2] dipolar cycloaddition of 1,2-diazinium ylides to the corresponding dipolarophiles. The synthesis was performed under microwave and ultrasound (US) irradiation as well as under conventional thermal heating. The most effective conditions in term of yields and time were found to be US irradiation. The penta- and tetra-cyclic 1,2-diazines were evaluated for their in vitro anticancer activity. The pentacyclic 1,2-diazine derivatives exhibit a significant anticancer activity against Non-Small Cell Lung Cancer NCI-H460, Leukemia MOLT-4, Leukemia CCRF-CEM, and Breast Cancer MCF7. A feasible explanation for anticancer efficiency of the pentacyclic 1,2-diazines have been furnished, being correlated with the mechanisms of action. The synthesis (conventional thermal heating, microwave and ultrasound irradiation), structure, and in vitro anticancer activity of a new class of anticancer molecules with polycyclic 1,2-diazines skeleton is presented.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 1008-72-6, Name is Sodium 2-formylbenzenesulfonate, molecular formula is C7H5NaO4S, belongs to phthalazine compound. In a document, author is Nejad, Fateme Khajoee, introduce the new discover, Recommanded Product: Sodium 2-formylbenzenesulfonate.

A tridentate Schiff base ligand, (E)-3-((2-hydroxy-3-methoxybenzylidene)amino)-2-methylquinazolin-4(3H)-one [HL], and its mixed-ligand Ni(II) complex [Ni(L)(imi)], were synthesized and fully characterized using elemental analysis, FT-IR, UV-Vis and (HNMR)-H-1 spectroscopy techniques. The structure of the synthesized ligand and complex was determined with single crystal X-ray diffraction method. In the complex, a square planner geometry was observed around the Ni(II) central atom coordinated with the donor atoms of the Schiff base ligand and one nitrogen of imidazole group. In addition, the catalytic activity of the complex on the three-component condensation of hydrazine hydrate with phthalic anhydride and dimedone to obtain 2H-indazolo[2,1-b]phthalazine-triones was investigated. Furthermore, in-vitro antimicrobial studies were performed that indicated the great antibacterial activities of the Ni(II) complex against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus cereus bacteria.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 56-95-1, Name is Chlorhexidine Diacetate, molecular formula is C26H38Cl2N10O4, belongs to phthalazine compound. In a document, author is Wei, Cheng-Xi, introduce the new discover, Quality Control of Chlorhexidine Diacetate.

In a previous research, we synthesized and evaluated the anticonvulsant activity of a series of 6-substituted-oxy-[1,2,4] triazolo[3,4-a] phthalazine compounds. Reference to other studies, we deduce that the compounds may be useful for regulating inotropic activity by effecting stroke volume, so in this study, we evaluated 20 compounds (15a-t) for their changed inotropic activity by measuring the left atrium stroke volume in heart preparations isolated from Wistar rats. Among the 20 compounds, 15j was the most potent with an increased stroke volume of 27.39 +/- 3.16 % at the concentration of 50 mu M, compound 15m was identified as the most potent with an decreased stroke volume of -95.59 +/- 0.50 % at the same concentration which is much more effective than referenced drug Nifedipine (-55.22 +/- 1.87% at the concentration of 1 mu M).

Cu@Fe3O4 MNPs as novel nanomagnetic reagents were prepared to investigate their catalytic behavior in the preparation of tetrahydrobenzimidazo[2,1-b]quinazolin-1(2H)-ones, as important biologically active compounds. Then, characterization of the synthesized nanoparticles was performed using different methods including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) analysis, thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), energy dispersive X-ray (EDX), and scanning electron microscopy (SEM). All reactions were performed with small amounts of the Cu@Fe3O4 MNPs under solvent-free conditions. After completion of the reaction, because of the magnetic nature of the nanocatalyst, they could be simply separated with an external magnet and easily reused with no considerable decrease in the catalytic behavior even after seven runs.

Application of 5509-65-9, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 5509-65-9, Name is 2,6-Difluoroaniline, SMILES is C1=CC=C(C(=C1F)N)F, belongs to phthalazine compound. In a article, author is Amano, Takayuki, introduce new discover of the category.

Dantrolene is used for malignant hyperthermia during anesthesia, and it sometimes causes severe liver injury as a side effect. Dantrolene is metabolized to acetylaminodantrolene, which is formed via the reduction of dantrolene to aminodantrolene and subsequent acetylation. Formation of hydroxylamine during the metabolic process may be associated with liver injury. We identified the enzymes responsible for dantrolene metabolism in humans to elucidate the mechanism of liver injury. Dantrolene reductase activity was not detected in human liver microsomes, but it was detected in cytosol. Formation was increased in the presence of N-1-methylnicotineamide, which is an electron donor to aldehyde oxidase 1 (AOX1). Potent inhibitors of AOX1 and a correlation study with a marker of AOX1 activity, namely phthalazine oxidase activity, in a panel of 28 human liver cytosol samples supported the role of AOX1 in dantrolene reduction. Acetylaminodantrolene formation from aminodantrolene was highly detected in recombinant N-acetyltransferase (NAT) 2 rather than NATI. A glutathione trapping assay revealed the formation of hydroxylamine via an AOX1-dependent reduction of dantrolene but not via hydroxylation of aminodantrolene. In conclusion, we found that AOX1 and NAT2 were responsible for dantrolene metabolism in humans and that AOX1-dependent metabolism determines dantrolene-induced liver injury.
