  Synthesis and evaluation of ureido and vinylureidopenicillins as inhibitors of intraruminal lactic acid production

  摘要：

  A series of 14 vinylureidopenicillins and a series of 9 ureidopenicillins were prepared by reaction of 6-aminopenicillanic acid with vinyl isocyanates and isocyanates. These compounds were evaluated for their potential to protect ruminants against lactic acidosis. The compounds were tested for inhibition of in vitro ruminal lactic and propionic acid production, and six compounds inhibited lactic acid production to less than 10% of control at doses of 0.31 microgram/mL or lower, whereas they did not inhibit propionic acid production at doses greater than 10 micrograms/mL. The most active compounds also were screened for general antibacterial activity and were found to be weakly active against Gram-positive bacteria. The structure--activity relationships are discussed for both series. Triethylammonium 6-[3[2-(4-tert-butylphenyl)vinyl]ureido]penicillanate (4) was chosen for evaluation as an inhibitor of intraruminal lactic acidosis in vivo.

  Non-acidic antiinflammatory compounds II. Synthesis and activity of 6-amino-2,4-lutidine derivatives

  摘要：

  Benzamides I, phenylalkanamides II and cinnamamides III are structurally related to the antiinflammatory N-(4,6-dimethylpyridin-2-yl)benzamide 1. These were synthesized and the transformation of the 2-aminopyridine nucleus of benzamides I into a 2-imino-1,2-dihydropyridine structure (compounds IV) was also carried out. Of the 49 new derivatives, the 3-fluorobenzamide 9 was the most potent in the oral treatment of carrageenen-induced peripheral edema; IC50 = 12.2 mg.kg(-1). It was 3 times as active as benzamide 1, but the latter nevertheless had a better therapeutic index (LD(50)/IC50) of 52 against 23. Benzamide 1, a non-acidic antiinflammatory compound devoid of any blocking activity on cyclooxygenase, markedly reduces the production of reactive oxygen species in rat peritoneal macrophages. This compound probably acts at the membrane, perhaps by interference with transmembrane events.

The relative efficiency of a range of acids (trifluoroacetic, difluoroacetic, acetic, triflic) is assessed showing TFA and TfOH as the most efficient and acetic acid as a totally inefficient reaction promoter. The new procedure complements the Lewis acid promoted reaction previously described by our group in two aspects: First, stereodivergent results are obtained for the Lewis acid

  证明了单独使用布朗斯台德酸有效促进 N-烯酰基恶唑烷-2-硫酮中的硫转移过程以产生 β-巯基羰基衍生物的能力。该反应对一系列烷基取代的 N-烯酰基恶唑烷-2-硫酮（dr 通常高于 98:2）进行了基本上完美的非对映控制，并且对大多数芳基取代的对应物（dr 通常高于 92:8）具有高选择性。重要的是，该反应在 β,β-二取代的 N-烯酰基恶唑烷-2-硫酮中也非常有效，产生选择性通常高于 95:5 的四元 CS 立体中心。评估了一系列酸（三氟乙酸、二氟乙酸、乙酸、三氟甲磺酸）的相对效率，显示 TFA 和 TfOH 是最有效的，而乙酸则是完全低效的反应促进剂。新程序在两个方面补充了我们小组先前描述的路易斯酸促进反应：首先，对路易斯酸或布朗斯台德酸促进的β，β-二取代烯酰基化合物的反应获得了立体发散结果。其次，虽然布朗斯台德酸促进的反应是立体有择的，在底物 E/Z 构型和产物立体化学之间提供了良好的相关性，但由路易斯酸

  Nitrofurans undergo intramolecular Diels–Alder reactions with tethered electron-poor dienophiles more rapidly and in higher yield than non-nitrated furans. Computational studies indicate that increased stabilization of a partial positive charge on the nitro-substituted carbon in both transition state and product is the driving force for these reactions. Frontier molecular orbital energy differences

  与未硝化的呋喃相比，硝基呋喃经历分子内的Diels-Alder反应时，系留电子贫乏的双亲亲烯体的速度更快且产率更高。计算研究表明，在过渡态和产物中，硝基取代碳上部分正电荷的稳定性提高是这些反应的驱动力。前沿的分子轨道能量差异表明硝化后从正电子需求到反电子需求的转换。呋喃和硝基呋喃之间的芳族稳定能似乎没有差异。计算表明，硝基呋喃反应通过高度异步的过渡态进行，从而更容易在两个空间位阻的碳之间形成键。

  A bio-inspired, photocatalytic E → Z isomerization of cinnamides is reported using inexpensive (−)-riboflavin (vitamin B2) under irradiation at λ = 402 nm. This operationally simple transformation is compatible with a range of amide derivatives including –NR2, –NHSO2R and N(Boc)2 (up to 99:1 Z:E). Selective energy transfer from the excited state photocatalyst to the starting E-isomer ensures that directionality
