In an article，Which mentioned a new discovery about 2213-63-0

The reaction of o-phenylene diamine and ethyl oxamate is reinvestigated and led to 3-aminoquinoxalin-2(1H)-one rather than benzimidazole-2-carboxamide as was previously reported. The structure of the obtained quinoxaline has been confirmed by X-ray. The anti-tumor activity of synthesized quinoxalines 1-21 has been evaluated by studying their possible inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13- acetate (TPA). Among the studied compounds 1-21, compounds 12, 8, 13, 18, 17 and 19, respectively, demonstrated strong inhibitory effects on the EBV-EA activation without showing any cytotoxicity and their effects being stronger than that of a representative control, oleanolic acid. Furthermore, compound 12 exhibited a remarkable inhibitory effect on skin tumor promotion in an in vivo two-stage mouse skin carcinogenesis test using 7,12-dimethylbenz[a]anthracene (DMBA) as an initiator and TPA as a promoter. The result of the present investigation indicated that compound 12 might be valuable as a potent cancer chemopreventive agent. Moreover, the molecular docking into PTK (PDB: 1t46) has been done for lead optimization of the aforementioned compounds as potential PTK inhibitors.

In a article，once mentioned of 2213-63-0

A series of novel quinoxaline derivatives linked to a pyridine moiety through phenylamino or phenoxy residue was synthesized and evaluated as candidate anticonvulsants. The synthesis was achieved through reaction of 2,3-dichloroquinoxaline (1) with an equimolar amount of 4-aminoacetophenone to give compound 2 which is considered as an important synthon for the construction of a pyridine ring via several synthetic routs. Some compounds were synthesized through formation of the intermediate alpha,beta-unsaturated compounds which, in turn, were allowed to react with malononitrile to give the corresponding alkoxypyridines (8-17). Compounds 18-21 were synthesized by a one-pot simple reaction between 2, the appropriate aldehyde, and malononitrile in sodium alkoxide solution. Moreover, they can be synthesized through reaction of compound 2 and arylidenemalononitrile in sodium alkoxide. The phenoxy analogues were prepared by reaction of 1 with 4-hydroxyacetophenone or 3-hydroxybenzaldehyde to give 22 and 27, respectively. These compounds, in turn, were allowed to react with malononitrile and the proper carbonyl compound in presence of sodium alkoxide in a one-pot reaction technique to give the target compounds. Biological evaluation of the prepared compounds showed that some of them are potent anticonvulsant agents. The detailed synthesis, spectroscopic and biological data are reported.

The controllable switching of suitably bridged resorcin[4]arene cavitands between a “vase” conformation, with a cavity capable of guest inclusion, and a “kite” conformation, featuring an extended flattened surface, provides the basis for ongoing developments of dynamic molecular receptors, sensors, and molecular machines. This paper describes the synthesis, X-ray crystallographic characterization, and NMR analysis of the “vase-kite” switching behavior of a fully pyrazine-bridged cavitand and five other mixed-bridged quinoxaline-bridged cavitands with one methylene, phosphonate, or phosphate bridge. The pyrazine-bridged resorcin[4]arene cavitand displayed an unexpectedly high preference for the kite conformation in nonpolar solvents, relative to the quinoxaline-bridged analogue. This observation led to extensive solvent-dependent switching studies that provide a detailed picture of how solvent affects the thermal vase-kite equilibration. As for any thermodynamic process in the liquid phase, the conformational equilibrium is affected by how the solvent stabilizes the two individual states. Suitably sized solvents (benzene and derivatives) solvate the cavity of the vase form and reduce the propensity for the vase-to-kite transition. Correspondingly, the kite geometry becomes preferred in bulky solvents such as mesitylene, incapable of penetrating the vase cavity. As proposed earlier by Cram, the kite form is preferred at low temperatures due to the more favorable enthalpy of solvation of the enlarged surface. Furthermore, the kite conformation is more preferred in solvents with substantial hydrogen-bonding acidity: weak hydrogenbonding interactions between the mildly basic quinoxaline and pyrazine nitrogen atoms and solvent molecules are more efficient in the open kite than in the closed vase form. Vase-to-kite conversion is entirely absent in dipolar aprotic solvents lacking any H-bonding acidity. Thermal vase-kite switching requires fully quinoxaline- or pyrazinebridged cavitands, whereas pH-controlled switching is also applicable to systems incorporating only two or three such bridges.

Urea transporter A (UT-A) isoforms encoded by the Slc14a2 gene are expressed in kidney tubule epithelial cells, where they facilitate urinary concentration. UT-A1 inhibition is predicted to produce a unique salt-sparing diuretic action in edema and hyponatremia. Here we report the discovery of 1,2,4-triazoloquinoxalines and the analysis of 37 synthesized analogues. The most potent compound, 8ay, containing 1,2,4-triazolo[4,3-a]quinoxaline-substituted benzenesulfonamide linked by an aryl ether, rapidly and reversibly inhibited UT-A1 urea transport by a noncompetitive mechanism with IC50 ? 150 nM; the IC50 was ?2 muM for the related urea transporter UT-B encoded by the Slc14a1 gene. Molecular modeling suggested a putative binding site on the UT-A1 cytoplasmic domain. In vitro metabolism showing quinoxaline ring oxidation prompted the synthesis of metabolically stable 7,8-difluoroquinoxaline analogue 8bl, which when administered to rats produced marked diuresis and reduced urinary osmolality. 8bl has substantially improved UT-A1 inhibition potency and metabolic stability compared with prior compounds.
