  • One-Pot Construction of Indolo[2,3-<i>b</i>]quinoxalines through Ruthenium-Catalyzed <i>Ortho</i> C–H Bond Functionalization of 2-Arylquinoxalines with Sulfonyl Azides
    作者:Sudip Laru、Suvam Bhattacharjee、Sumit Ghosh、Alakananda Hajra

    N-substituted indolo[2,3-b]quinoxalines has been developed through a Ru(II)-catalyzed ortho C–H functionalization of 2-arylquinoxalines with sulfonyl azides and further oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone in one pot. This double C–N bond formation strategy provides a new efficient route for the preparation of a series of biologically relevant 6H-indolo[2,3-b]quinoxaline derivatives in
    N-取代的吲哚并[2,3- b ]喹喔啉的合成是通过Ru(II)催化的2-芳基喹喔啉与磺酰叠氮化物的邻位C-H官能化并用2,3-二氯-5进一步氧化而开发的, 6-二氰基-1,4-苯醌一锅。这种双C-N键形成策略为制备一系列生物相关的6 H-吲哚[2,3- b ]喹喔啉衍生物提供了一条新的有效途径,产率高达94%,表明底物适用范围广泛。初步的机理研究表明,连续的 C-N 键形成是通过第一步中五元钌环中间体的形成和第二步中自由基机制的形成进行的。
  • Quinoxaline Derivatives: Novel and Selective Butyrylcholinesterase Inhibitors

    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。
  • Synthesis of functionalized benzimidazoles and quinoxalines catalyzed by sodium hexafluorophosphate bound Amberlite resin in aqueous medium

    for the selective synthesis of 1,2-disubstituted benzimidazoles and quinoxalines in water–methanol (1:1) mixture with the aid of resin bound hexafluorophosphate ion as catalyst is reported. The method is also effective for the incorporation of quinoxaline nucleus at the A ring of pentacyclic triterpenoid, friedelin. A plausible mechanism for the formation of disubstituted benzimidazole has also been suggested
