  邻苯二酚和邻苯二酚衍生物作为幽门螺杆菌脲酶抑制剂的合成，结构和活性评价

  摘要：

  合成了一些邻苯三酚和邻苯二酚衍生物，并使用众所周知的幽门螺杆菌脲酶抑制剂乙酰氧肟酸（AHA）作为阳性对照，评估了它们对脲酶的抑制活性。测定结果表明许多化合物已显示出对幽门螺杆菌脲酶的潜在抑制活性。已发现4-（4-羟基苯乙基）phen-1,2-二醇（2a）是最有效的脲酶抑制剂，提取分数的IC 50值为1.5±0.2μM，完整细胞的IC 50值为4.2±0.3μM，至少10分别比AHA低2倍和20倍（IC 50为17.2±0.9μM，100.6±13μM）。这一发现表明2a潜在的脲酶抑制剂将值得进一步研究。为了理解所观察到的良好活性，进行了2a到幽门螺杆菌脲酶活性位点的分子对接。

  Selective Acylation of Phenols in Boron Trifluoride Diethyl Etherate Solution and the Mechanistic Implication

  摘要：

  在三氟化硼二乙醚合物（BF3·OEt2）的存在下，酚类化合物直接与游离羧酸酰化反应具有化学选择性和区域选择性，并且没有观察到脱甲基化现象。BF3·OEt2的导向效应归因于硼三氟化物-酚羟基络合物的大位阻，这阻碍了邻位酰化的发生。微波照射不能改变BF3·OEt2的区域选择性，除了反应时间大大缩短。

• Polyphenols based on isoflavones as inhibitors of Helicobacter pylori urease

  Twenty polyphenols were synthesized and evaluated for their effect on Helicobacter pylori urease. Among these compounds, 4-(p-hydroxyphenethyl)pyrogallol (15) (IC50 = 0.03 mM) and 7,8,4'-trihydroxyisoflavone (19) (IC50 = 0.14 mM) showed potent inhibitory activities, and inhibited Helicobacter pylori urease in a time-dependent manner. The structure-activity relationship of these polyphenols revealed: the two ortho hydroxyl groups were essential for inhibitory activity of polyphenol. When the C-ring of isoflavone was broken, the inhibitory activity markedly decreased. As for deoxybenzoin, the carboxyl group was clearly detrimental. (c) 2007 Elsevier Ltd. All rights reserved.
• Amines and oximes derived from deoxybenzoins as Helicobacter pylori urease inhibitors

  Twenty amines and oximes from deoxybenzoins were prepared and evaluated for their inhibitory activity against Helicobacter pylori urease. Among these compounds, high inhibitory activities were observed in amines and oximes, especially amines 1b (IC50 = 0.011 mM) and 6b (IC50 = 0.047 mM) exhibited good in vitro activities, and were comparable to acetohydroxamic acid (AHA). The hydroxyl groups on deoxybenzoin skeleton may be responsible for the inhibitory activity and coordinate with the nickel (active site) on enzyme. A direct interaction may exist between the OH group of hydroxylamines or NH group of amines and His alpha 323 of H. pylori urease, which is on the flap of the enzyme active site.
