-
Paragraph 0307; 0309, (2019/02/02)
The invention provides a novel D- amino acid oxidase inhibitor and a preparation and application thereof. In particular, the invention discloses derivatives of quinoxaline-2,3-diketone, which has a novel structure shown in formula A, as well as a preparation method thereof and an application as an inhibitor of D-amino acid oxidase (DAAO). The compound provided by the invention shows excellent effects of analgesia and blocking morphine analgesia tolerance, and has application value for analgesia, treating opiate drug tolerance, and anti-schizophrenia.
Kinetic Studies of the Mechanism of the Nitraminopyridine Rearrangement

Rate data are reported for the rearrangement, in 92percent sulfuric acid at 30 deg C, of a series of 4-X-2-nitraminopyridines (X=H, Me, Br, Cl, MeO, CO2H) and of 4-methyl-2-nitramino(3-D)-pyridine.Values of pKa for second protonation of the corresponding pyridin-2-amines were also measured and rate constants for nitration of the monoprotonated pyridinamines were thereby calculated.The results suggest that the rate-determining step occurs prior to formation of the appropriate 3- and 5-nitro ? complexes.The nature of this step is not clear, however, and a key role for the nitramine itself is not proven by the current evidence
