• 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

  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。

  We have previously identified the 7,8,9,10-tetrahydro-7,10-ethano-1,2,4-triazolo[3,4-a]phthalazine (1) as a potent partial agonist for the alpha(3) receptor subtype with 5-fold selectivity in binding affinity over alpha(1). This paper describes a detailed investigation of the substituents on this core structure at both the 3- and 6-positions. Despite evaluating a wide range of groups, the maximum selectivity

  我们之前已经确定了7,8,9,10-四氢-7,10-乙醇-1,2,4-三唑并[3,4-a]酞嗪（1）是α（3）的有效部分激动剂。受体亚型，对α（1）的结合亲和力具有5倍的选择性。本文描述了在此核心结构的3位和6位上的取代基的详细研究。尽管评估了广泛的组，但相对于alpha（1）亚型，对alpha（3）亚型的亲和力可达到的最大选择性是12倍（对于57）。尽管大多数类似物在功效上均未显示选择性，但一些类似物确实在α（1）处表现出部分激动作用，而在α（3）处表现出拮抗作用（例如25和75）。但是，测试了两个类似物（93和96），它们都在6位上有三唑取代基，显示出对alpha（3）亚型的疗效明显高于alpha（1）亚型。这是该系列中可以在所需方向上实现选择性的第一个迹象。

  Current study based on the synthesis of new thiazole derivatives via "one pot" multicomponent reaction, evaluation of their in vitro α-glucosidase inhibitory activities, and in silico studies. All synthetic compounds were fully characterized by (1)H NMR, (13)C NMR and EIMS. CHN analysis was also performed. These newly synthesized compounds showed activities in the range of IC50=9.06±0.10-82.50±1.70μM

  A novel series of 5-(aroylhydrazinocarbonyl)escitalopram (58–84) have been designed, synthesized and tested for their inhibitory potential against cholinesterases. 3-Chlorobenzoyl- (71) was found to be the most potent compound of this series having IC50 1.80 ± 0.11 μM for acetylcholinesterase (AChE) inhibition. For the butyrylcholinesterase (BChE) inhibition, 2-bromobenzoyl- (76) was the most active

  已经设计，合成和测试了一系列新型的5-（芳酰基肼基羰基）依他普仑（58-84）对胆碱酯酶的抑制潜力。发现3-氯苯甲酰基- （71）是该系列中最有效的化合物，对乙酰胆碱酯酶（AChE）的抑制作用的IC 50为1.80±0.11μM。对于丁酰胆碱酯酶（BChE）抑制，2-溴苯甲酰基-（76）是该系列中活性最高的化合物，IC 50为2.11±0.31μM。构效关系说明温和的给电子基团增强了酶的抑制作用，而吸电子基团降低了除o -NO 2以外的抑制。然而，取代基的大小和位置影响酶抑制。。在AChE的对接研究中，配体71、72和76分别显示5874、5756和5666以及ACE的得分分别为-64.92，-203.25和-140.29 kcal / mol。在BChE的情况下，配体71、76和81分别显示出ACE值为-170.91，-256.84和-235.97 kcal / mol的高分6016、6150和5994。
