  • Quinoxaline Derivatives: Novel and Selective Butyrylcholinesterase Inhibitors
    作者:Aurang Zeb、Abdul Hameed、Latifullah Khan、Imran Khan、Kourosh Dalvandi、M. Choudhary、Fatima Basha

    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。

    Metal-free and external-oxidant-free aerobic oxidative reactions of 2-hydroxyacetophenones are developed. The reactions are based on the aerobic formation of small equilibrium quantities of 2-keto aldehydes. Phthalides, quinoxalines, α-keto amides, and olefins can be formed in moderate to good yields directly from alcohols. DIPEA = diisopropylethylamine.
