Synthetic Route of 15804-19-0, New research progress on 15804-19-0 in 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 15804-19-0, Name is Quinoxaline-2,3(1H,4H)-dione, molecular formula is C8H6N2O2. In a Article，once mentioned of 15804-19-0

A series of 1,2,3,4-tetrahydroquinoline-2,3,4-trione 3-oximes (QTOs) was synthesized and evaluated for antagonism of NMDA receptor glycine site. Glycine site affinity was determined using a [3H]DCKA binding assay in rat brain membranes and electrophysiologically in Xenopus oocytes expressing 1a/2C subunits of cloned rat NMDA receptors. Selected compounds were also assayed for antagonism of AMPA receptors in Xenopus oocytes expressing rat brain poly-(A)+ RNA. QTOs were prepared by nitrosation of 2,4- quinolinediols. Structure-activity studies indicated that substitutions in the 5-, 6-, and 7-positions increase potency, whereas substitution in the 8- position causes a decrease in potency. Among the derivatives evaluated, 5,6,7-trichloro-QTO was the most potent antagonist with an IC50 of 7 nM in the [3H]DCKA binding assay and a K(b) of 1-2 nM for NMDA receptors expressed in Xenopus oocytes. 5,6,7-Trichloro-QTO also had a K(b) of 180 nM for AMPA receptors in electrophysiological assays. The SAR of QTOs was compared with the SAR of 1,4-dihydroquinoxaline-2,3-diones (QXs). For compounds with the same benzene ring substitution pattern, QTOs were generally 5-10 times more potent than the corresponding QXs. QTOs represent a new class of inhibitors of the NMDA receptor which, when appropriately substituted, are among the most potent glycine site antagonists known.

The title compound, 2,3-diketo-benzopiperazine, has been synthesized and characterized by elemental analysis, IR, electronic spectroscopy and single crystal X-ray diffraction. Ab initio calculations of the structure, natural bond orbital, topological analysis and thermodynamic functions of the title compound were performed at HF/6-311G** and B3LYP/6-311G** levels of theory. Vibrational frequencies were also predicted, assigned, compared with the experimental values, and they supported each other. Electronic absorption spectra were calculated by the time-dependent density functional theory, which indicates that the two absorption bands are mainly derived from the contribution of bands pi?pi*. The calculation of the second order optical non-linearity was carried out, and the molecular hyperpolarisability was 3.282×10-30 esu.

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

Treatment of 2,3-dichloroquinoxalines with 2-amino-6-picoline-3-thiol gave a mixture of 2,3-bis(2-amino-6-picolinyl-3-thio)quinoxalines (16, R = H, Cl) and 2,3-bis (N,N-dimethylamino)quinoxalines (15, R = H, Cl) separated by fractional crystallization. A similar reaction of 3-amino-6-methoxypyridine-2(1H)-thione (9) with 4,5-dichloropyridazin-3(2H)-one (21) gave 4-chloro-5-(3-amino-6-methoxypyridyl-2-thio)pyridazin-3(2H)-one (22). Concentrated hydrochloric acid-catalysed cyclization of 22 gave the nonrearranged 7-methoxy-2,3,6-triazaphenothiazin-1(2H)-one. The action of compound 22 in refluxing glacial acetic acid gave, on the other hand, 7-methoxy-2,3,6-triazaphenothiazin-4(3H)-one via a Smiles rearrangement. These cyclized compounds are the first known derivatives of the new 2,3,6-triazaphenothiazine ring system.
