  Hydroxyl radical scavenging by edaravone derivatives: Efficient scavenging by 3-methyl-1-(pyridin-2-yl)-5-pyrazolone with an intramolecular base

  摘要：

  We synthesized various 3-methyl-1-phenyl-5-pyrazolone (edaravone) derivatives and evaluated their oxidation potential and hydroxyl radical scavenging activity. It was found 3-methyl-1-(pyridin-2-yl)-5-pyrazolone had a much higher ability to scavenge the radical than did edaravone itself. Its efficient radical scavenging activity was assumed to be due to the increase of its anion form, an active form, by a hydrogen-bonded intramolecular base.

• A Dinuclear Palladium Catalyst for α-Hydroxylation of Carbonyls with O₂

  日期：2011.2.16

  A chemo- and regioselective α-hydroxylation reaction of carbonyl compounds with molecular oxygen as oxidant is reported. The hydroxylation reaction is catalyzed by a dinuclear Pd(II) complex, which functions as an oxygen transfer catalyst, reminiscent of an oxygenase. The development of this oxidation reaction was inspired by discovery and mechanism evaluation of previously unknown Pd(III)-Pd(III)

  报道了羰基化合物与分子氧作为氧化剂的化学和区域选择性α-羟基化反应。羟基化反应由双核 Pd(II) 络合物催化，该络合物起到氧转移催化剂的作用，让人想起加氧酶。这种氧化反应的发展受到先前未知的 Pd(III)-Pd(III) 配合物的发现和机理评估的启发。
• New Series of Antiprion Compounds:  Pyrazolone Derivatives Have the Potent Activity of Inhibiting Protease-Resistant Prion Protein Accumulation

  To find effective antiprion compounds, we synthesized and evaluated various pyrazolone derivatives. Seven of 19 compounds showed inhibition of PrP-res accumulation and the remarkably active compound 13 showed an IC50 value of 3 nM in both ScN2a and F3 cell lines. Findings from studies on physicochemical and biochemical properties suggest that the action mechanism of these compounds does not correlate

  为了找到有效的抗pr病毒化合物，我们合成并评估了各种吡唑啉酮衍生物。19种化合物中的7种显示出对PrP-res积累的抑制作用，而显着活性的化合物13在ScN2a和F3细胞系中的IC50值为3 nM。从理化和生物化学性质的研究发现表明，这些化合物的作用机理与任何抗氧化剂活性，任何羟基自由基清除活性或任何SOD样活性均不相关。
