  Investigation and Application of Amphoteric α-Amino Aldehyde: An in Situ Generated Species Based on Heyns Rearrangement

  摘要：

  In situ generation of the reactive amphoteric a amino aldehyde with simple alpha-hydroxy ketones and phenyl amine-via Heyns rearrangement was proven to be feasible. Metal-free domino reactions based on this reactive intermediate were effectively used to afford important N-heterocycles including polysubstituted pyrroles, indoles, and quinoxalines conveniently. A simple starting material, water as the only byproduct, and diversity of the useful products will make this method greatly attractive for pharmaceutics.

  Various 2-aryl quanoxalines were synthesized with good yields from o-phenylene diamines and phenacyl bromides in one pot using novel nanocrystalline 5 % Fe/ZnO catalyst, at room temperature. The salient feature of this method includes mild reaction conditions, short reaction time, good yield, high purity of product, and recyclable catalyst without noticeable decrease in catalytic activity, which can be used for large-scale synthesis.

  Alzheimer's disease (AD) is a progressive brain disorder which occurs due to lower levels of acetylcholine (ACh) neurotransmitters, and results in a gradual decline in memory and other cognitive processes. Acetycholinesterase (AChE) and butyrylcholinesterase (BChE) are considered to be primary regulators of the ACh levels in the brain. Evidence shows that AChE activity decreases in AD, while activity of BChE does not change or even elevate in advanced AD, which suggests a key involvement of BChE in ACh hydrolysis during AD symptoms. Therefore, inhibiting the activity of BChE may be an effective way to control AD associated disorders. In this regard, a series of quinoxaline derivatives 1-17 was synthesized and biologically evaluated against cholinesterases (AChE and BChE) and as well as against α- chymotrypsin and urease. The compounds 1-17 were found to be selective inhibitors for BChE, as no activity was found against other enzymes. Among the series, compounds 6 (IC50 = 7.7 ± 1.0 µM) and 7 (IC50 = 9.7 ± 0.9 µM) were found to be the most active inhibitors against BChE. Their IC50 values are comparable to the standard, galantamine (IC50 = 6.6 ± 0.38 µM). Their considerable BChE inhibitory activity makes them selective candidates for the development of BChE inhibitors. Structure-activity relationship (SAR) of this new class of selective BChE inhibitors has been discussed.

  阿尔茨海默病（AD）是一种渐进性脑部疾病，由于乙酰胆碱（ACh）神经递质水平降低而发生，导致记忆和其他认知过程逐渐衰退。乙酰胆碱酯酶（AChE）和丁酰胆碱酯酶（BChE）被认为是大脑中ACh水平的主要调节因子。证据显示，AD中AChE活性降低，而BChE活性不变甚至在前期的AD中升高，这表明在AD症状期间BChE在ACh水解中的关键作用。因此，抑制BChE活性可能是控制与AD相关障碍的有效方法。在这方面，合成了一系列喹喉化合物1-17，并对其对胆碱酯酶（AChE和BChE）以及α-胰凝乳蛋白酶和尿素酶的生物活性进行了评估。化合物1-17被发现是BChE的选择性抑制剂，因为它们对其他酶没有活性。在系列中，化合物6（IC50 = 7.7 ± 1.0 µM）和7（IC50 = 9.7 ± 0.9 µM）被发现是BChE的最有效抑制剂。它们的IC50值与标准药物加兰他敏（IC50 = 6.6 ± 0.38 µM）相当。它们显著的BChE抑制活性使它们成为开发BChE抑制剂的有选择性候选物。这一新类选择性BChE抑制剂的构效关系（SAR）已被讨论。
