  摘要：

  替代苯胺和苯磺酰氯的反应已被用于制备49种通式为4-X-C₆H₄SO₂NHC₆H₄-Y-4'的取代N-苯基苯磺酰胺。它们的纯度通过元素分析进行了检查。取代基X和Y包括H、CH₃、CH₃O、Cl、Br、CN和NO₂。所有化合物的解离常数通过在甲醇、乙腈、N,N-二甲基甲酰胺和吡啶中的电位滴定确定。获得的解离常数pKHA与各种取代基常数相关联。发现取代基X和Y对解离的影响最好通过使用带有σp常数的Hammett方程和带有σp-和σp常数的Yukawa-Tsuno方程来描述。这一结果证实了Y取代基与反应中心的直接共轭。在所有使用的溶剂中，使用加性模型解释的可变性超过96%。数据还提供了关于SO₂基团的传输效应的信息。平均解离常数进一步通过潜在变量方法、主成分和共轭偏差分析进行处理。

  Alcoholysis of N1-Arenesulfonyl-N1, N2-diarylacetamidines (1-30) was studied kinetically. The rate of the reaction between the substrates and ethoxide ion depended on the electron-withdrawing resonance effect of the substituents on both the N1-aryl and N2-aryl groups to a similar extent. The rate of the neutral alcoholysis depended on the resonance effect of the N1-aryl substituent to a larger extent than in the former reaction, and depended hardly at all on the electron-releasing resonance effect of the N2-aryl substituent, showing that the reaction does not proceed by the solvolysis mechanism.A reaction mechanism is proposed in which the rate-determining attack of the nucleophile is accompanied by the concerted departure of the N-arylarenesulfonamide group.

  对 N1-壬磺酰基-N1，N2-二芳基乙酰胺（1-30）的醇解进行了动力学研究。底物与乙氧离子的反应速率在类似程度上取决于 N1 芳基和 N2 芳基上取代基的吸电子共振效应。与前一种反应相比，中性醇解反应的速率在更大程度上取决于 N1-芳基取代基的共振效应，而几乎不取决于 N2-芳基取代基的电子释放共振效应，这表明该反应不是通过溶解机理进行的。

• Analgesic agents without gastric damage: Design and synthesis of structurally simple benzenesulfonanilide-type cyclooxygenase-1-selective inhibitors

  In order to create novel analgesic agents without gastric disturbance, structurally simple cyclooxygenase-1 (COX-1) inhibitors with a benzenesulfonanilide skeleton were designed and synthesized. As a result, compounds 11f and 15a, which possess a p-amino group on the benzenesulfonyl moiety and p-chloro group on the anilino moiety, showed COX-1-selective inhibition. Moreover compound 11f, which is the most potent compound in this study showed more potent analgesic activity than that of aspirin at 30 mg/kg by po. The anti-inflammatory activity and gastric damage, however, were very weak or not detectably different from aspirin. Since the structure of our COX-1 inhibitors are very simple, they may be useful as lead compounds for superior COX-1 inhibitors as analgesic agents without gastric disturbance.
