  Structure−Activity Relationships for the Binding of Arylpiperazines and Arylbiguanides at 5-HT₃ Serotonin Receptors

  摘要：

  Arylpiperazines are nonselective agents that bind at 5-HT3 serotonin receptors with moderate to high affinity, whereas 1-phenylbiguanide is a low-affinity but more selective 5-HT3 agonist. In an attempt to enhance the affinity of the latter agent, and working with the assumption that similarities might exist between the binding of the two types of agents, we formulated structure-activity relationships for the binding of the arylpiperazines and then incorporated those substituents, leading to high affinity for the arylpiperazines, into 1-phenylbiguanide. A subsequent investigation examined the structure-activity relationships of the arylbiguanides and identified arylguanidines as a novel class of 5-HT3 ligands. Although curious similarities exist between the structure-activity relationships of the arylpiperazines, arylbiguanides, and arylguanidines, it cannot be concluded that all three series of compounds are binding in the same manner. Furthermore, upon investigating pairs of compounds in the three series, the arylpiperazines behaved as 5-HT3 antagonists (von Bezold-Jarisch assay) whereas the arylbiguanides and arylguanidines acted as 5-HT3 agonists.

• The α-Effect in Hydrazinolysis of 4-Chloro-2-Nitrophenyl X-Substituted-Benzoates: Effect of Substituent X on Reaction Mechanism and the α-Effect

  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。

  This Letter describes the continued optimization of the MLPCN probe molecule ML071. After introducing numerous cyclic constraints and novel substitutions throughout the parent structure, we produced a number of more highly potent agonists of the M-1 mACh receptor. While many novel agonists demonstrated a promising ability to increase soluble APP alpha release, further characterization indicated they may be functioning as bitopic agonists. These results and the implications of a bitopic mode of action are presented. (C) 2012 Elsevier Ltd. All rights reserved.
