Synthesis of new (trifluoromethyl)-1H-benzo[e][1,2,4]triazolo[1,2-a] [1,2,4]triazine-1,3(2H)-diones and (trifluoromethyl)benzo[5,6][1,2,4] triazino [1,2-b]phthalazine-8,13-diones

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.

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. Product Details of 92-92-2.

Mononuclear ruthenium compounds bearing N-donor and N-heterocyclic carbene ligands: structure and oxidative catalysis

A new CNNC carbene-phthalazine tetradentate ligand has been synthesised, which in the reaction with [Ru(T)Cl-3] (T = trpy, tpm, bpea; trpy = 2,2′; 6′, 2”’-terpyridine; tpm = tris(pyrazol-1-yl)methane; bpea = N, N-bis(pyridin-2-ylmethyl) ethanamine) in MeOH or iPrOH undergoes a C-N bond scission due to the nucleophilic attack of a solvent molecule, with the subsequent formation of the mononuclear complexes cis-[Ru(PhthaPz-OR)(trpy) X](n+), [Ru(PhthaPz-OMe)(tpm) X](n+) and trans, fac-[Ru(PhthaPz-OMe) (bpea) X] n+ (X = Cl, n = 1; X = H2O, n = 2; PhthaPz-OR = 1-(4-alkoxyphthalazin-1-yl)-3-methyl-1H-imidazol- 3-ium), named 1a(+)/2a(2+) (R = Me), 1b(+)/2b(2+) (R = iPr), 3(+)/4(2+) and 5(+)/6(2+), respectively. Interestingly, regulation of the stability regions of different Ru oxidation states is obtained by different ligand combinations, going from 6(2+), where Ru(III) is clearly stable and mono-electronic transfers are favoured, to 2a(2+)/2b(2+), where Ru(III) is almost unstable with regard to its disproportionation. The catalytic performance of the Ru-OH2 complexes in chemical water oxidation at pH 1.0 points to poor stability (ligand oxidation), with subsequent evolution of CO2 together with O-2, especially for 4(2+) and 6(2+). In electrochemically driven water oxidation, the highest TOF values are obtained for 2a(2+) at pH 1.0. In alkene epoxidation, complexes favouring bi-electronic transfer processes show better performances and selectivities than those favouring mono-electronic transfers, while alkenes containing electron-donor groups show better performances than those bearing electron-withdrawing groups. Finally, when cis-beta-methylstyrene is employed as the substrate, no cis/trans isomerization takes place, thus indicating the existence of a stereospecific process.

Identification of enzymes responsible for dantrolene metabolism in the human liver: A clue to uncover the cause of liver injury

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.
