📜2-氨基-6-甲基-5-硝基-3H-嘧啶-4-酮置于sodium Dithionite体系中,化学反应 24.5H,反应生成 2-氨基-3,5-二氢吡咯并[3,2-D]嘧啶-4-酮 参考文献:9-Benzoyl 9-Deazaguanines As Potent Xanthine Oxidase Inhibitors 标题:9-Benzoyl 9-Deazaguanines As Potent Xanthine Oxidase Inhibitors 摘要:A Novel Potent Xanthine Oxidase Inhibitor,3-Nitrobenzoyl 9-Deazaguanine (Lspn451),Was Selected From A Series Of 10 Synthetic Derivatives. The Enzymatic Assays Were Carried Out Using An On-Flow Bidimensional Liquid Chromatography (2D Lc) System,Which Allowed The Screening,The Measurement Of The Kinetic Inhibition Constant And The Characterization Of The Inhibition Mode. This Compound Showed A Non-Competitive Inhibition Mechanism With More Affinity For The Enzyme-Substrate Complex Than For The Free Enzyme,And Inhibition Constant Of 55.1 +/-9.80 Nm,About Thirty Times More Potent Than Allopurinol.
