  摘要：

  免疫调节剂被广泛用于治疗免疫介导的疾病，但现有药物的副作用很大，因此有必要寻找新的免疫调节剂。在此，我们研究了新的二茂铁-N-酰肼衍生物（SintMed(141-156)）的免疫调节活性。所评估的 N-酰肼在测试浓度下未显示出细胞毒性，其 CC50 值大于 50 µM。此外，所有二茂铁-N-酰肼都能调节永生巨噬细胞中亚硝酸盐的产生，抑制值介于 14.4% 和 74.2% 之间。二茂铁基-N-酰肼 SintMed149 和 SintMed150 的活性更强，它们的细胞毒性和抗炎效果也在腹腔巨噬细胞培养物中得到了评估。在腹腔巨噬细胞中测试的任何浓度下，这两种分子都没有细胞毒性，并且能够显著减少亚硝酸盐、TNF-α 和 IL-1β 的产生（p < 0.05）。有趣的是，这两种分子都能明显减少用 concanavalin A 激活的脾细胞中 IL-2 和 IFN-γ 的产生。最后，我们观察到，在急性腹膜炎模型中，二茂铁-N-酰腙 SintMed150 100 毫克/公斤的剂量可减少中性粒细胞的迁移（44.6%），在 LPS 诱导的内毒素休克模型中，动物存活率提高了 20%。这些发现表明，此类化合物具有治疗炎症性疾病的潜力。

• The α-Effect in Hydrazinolysis of 4-Chloro-2-Nitrophenyl X-Substituted-Benzoates: Effect of Substituent X on Reaction Mechanism and the α-Effect
  作者：Min-Young Kim、Tae-Eun Kim、Jieun Lee、Ik-Hwan Um

  日期：2014.8.20

  Second-order rate constants ($k_N$) have been measured spectrophotometrically for the reaction of 4-chloro-2-nitrophenyl X-substituted-benzoates (6a-6h) with a series of primary amines including hydrazine in 80 mol % $H_2O$/20 mol % DMSO at $25.0^\circ}C$. The Br$\o}$nsted-type plot for the reaction of 4-chloro-2-nitrophenyl benzoate (6d) is linear with $\beta}_nuc}$ = 0.74 when hydrazine is excluded from the correlation. Such a linear Br$\o}$nsted-type plot is typical for reactions reported previously to proceed through a stepwise mechanism in which expulsion of the leaving group occurs in the rate-determining step (RDS). The Hammett plots for the reactions of 6a-6h with hydrazine and glycylglycine are nonlinear. In contrast, the Yukawa-Tsuno plots exhibit excellent linear correlations with $\rho}_X$ = 1.29-1.45 and r = 0.53-0.56, indicating that the nonlinear Hammett plots are not due to a change in RDS but are caused by resonance stabilization of the substrates possessing an electron-donating group (EDG). Hydrazine is ca. 47-93 times more reactive than similarly basic glycylglycine toward 6a-6h (e.g., the $\alpha}$-effect). The $\alpha}$-effect increases as the substituent X in the benzoyl moiety becomes a stronger electron-withdrawing group (EWG), indicating that destabilization of the ground state (GS) of hydrazine through the repulsion between the nonbonding electron pairs on the two N atoms is not solely responsible for the substituent-dependent $\alpha}$-effect. Stabilization of transition state (TS) through five-membered cyclic TSs, which would increase the electrophilicity of the reaction center or the nucleofugality of the leaving group, contributes to the $\alpha}$-effect observed in this study.

  二次速率常数（$k_N$）已通过分光光度法测定，用于4-氯-2-硝基苯基X取代苯甲酸酯（6a-6h）与一系列伯胺（包括80摩尔% $H_2O$/20摩尔% DMSO中的25.0°C下的联氨）的反应。当联氨被排除在相关性之外时，4-氯-2-硝基苯基苯甲酸酯（6d）反应的Br$\o}$nsted型图是线性的，$\beta}_nuc}$ = 0.74。这种线性Br$\o}$nsted型图是典型的反应，先前报道这些反应通过逐步机制进行，其中离去基团的排出发生在速率决定步骤（RDS）中。6a-6h与联氨和甘氨酰甘氨酸反应的Hammett图是非线性的。相比之下，Yukawa-Tsuno图显示出极佳的线性相关性，$\rho}_X$ = 1.29-1.45，r = 0.53-0.56，表明非线性Hammett图并非由于RDS的变化，而是由于具有供电子基团（EDG）的底物的共振稳定化所导致。联氨对6a-6h的反应性大约是同样碱性的甘氨酰甘氨酸的47-93倍（例如，$\alpha}$效应）。随着苯甲酰基中取代基X成为更强的吸电子基团（EWG），$\alpha}$效应增加，表明通过两个N原子上的非键电子对之间的排斥来破坏联氨的基态（GS）并不是唯一导致取代基依赖的$\alpha}$效应的原因。通过五元环过渡态（TS）的稳定化，这将增加反应中心的亲电性或离去基团的离核性，有助于在本研究中观察到的$\alpha}$效应。
