  2,6-Difluorophenol as a Bioisostere of a Carboxylic Acid:  Bioisosteric Analogues of γ-Aminobutyric Acid

  摘要：

  3-(Aminomethyl)-2,6-difluorophenol (6) and 4-(aminomethyl)-2,6-difluorophenol (7) were synthesized in eight and four steps, respectively, starting from 2,6-difluorophenol, to test the potential of the 2,6-difluorophenol moiety to act as a lipophilic bioisostere of a carboxylic acid. Compounds 6 and 7 are potential bioisosteric analogues of gamma-aminobutyric acid (GABA). Substrate studies and inhibition studies were carried out with pig brain gamma-aminobutyric acid aminotransferase; 6 and 7 are very poor substrates, but both inhibit the enzyme, indicating that the 2,6-difluorophenol moiety appears to be able to substitute for a carboxylic acid to increase the lipophilicity of drug candidates.

  氟取代对扑热息痛的理化性质和止痛活性的影响。

  摘要：

  研究了6-羟基乙酰苯胺（对乙酰氨基酚）的六个氟化类似物的理化性质和止痛作用。与羟基相邻的氟取代增加了亲脂性和氧化电位，而与酰胺相邻的取代对亲脂性的影响很小，但导致氧化电位的增加更大。对于在2和6位具有氟的类似物，也缺乏酰胺基团和芳环的共平面性和共轭性。将氟引入对乙酰氨基酚的酰胺基团使亲脂性提高了4倍，并且还提高了对乙酰氨基酚的氧化电位。在苯醌诱导的雄性瑞士白老鼠的腹部收缩试验中，ED50的镇痛活性值表明，氟取代环可降低活性，特别是在2,6位 将氟引入酰胺基团显着增强了活性。镇痛作用与理化性质的关系表明，酰胺基团与芳环的共轭（和平面性）对于活性至关重要，并且容易氧化也可能是重要的因素。

  replacement of Cl by a more nucleophilic tBuO anion ligand, showed higher reactivity and para selectivity in the transformation of C–F to C–OtBu bond, distinctively different from that when only KOtBu was used (ortho selectivity) under the identical condition. Mechanistic studies including density functional theory calculations suggested a gold-mediated nucleophilic ligand attack of the C–F bond pathway
