  Design, synthesis and pharmacological evaluation of chalcone derivatives as acetylcholinesterase inhibitors

  摘要：

  A novel series of chalcone derivatives (4a-8d) were designed, synthesized, and evaluated for the inhibition activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). The logP values of the compounds were shown to range from 1.49 to 2.19, which suggested that they were possible to pass blood brain barriers in vivo. The most promising compound 4a (IC50: 4.68 mu mol/L) was 2-fold more potent than Rivastigmine against AChE (IC50: 10.54 mu mol/L) and showed a high selectivity for AChE over BuChE (ratio: 4.35). Enzyme kinetic study suggested that the inhibition mechanism of compound 4a was a mixed-type inhibition. Meanwhile, the result of molecular docking showed its potent inhibition of AChE and high selectivity for AChE over BuChE. (C) 2014 Elsevier Ltd. All rights reserved.

  设计，合成和生物评价的偶联的生物活性支架作为潜在的抗癌剂的二氢叶酸还原酶和硫氧还蛋白还原酶的双重目标。

  摘要：

  二氢叶酸还原酶（DHFR）和硫氧还蛋白还原酶（TrxR）酶参与肿瘤细胞的生长和存活过程。众所周知，4,6-二氨基-1,2-二氢-1,3,5-三嗪支架可作为抑制DHFR的有用支架，而据报道查耳酮是TrxR的抑制剂。在这项研究中，成功​​地合成和表征了通过4,6-二氨基-1,2-二氢-1,3,5-三嗪和查尔酮骨架的结构组合设计的15种新化合物。通过体外酶法评估时，所有化合物均显示出对DHFR和TrxR的双重抑制作用。这些化合物还对MCF-7和HCT116细胞显示出抗增殖活性。更强大的类似物14和15被发现抑制HCT116细胞中的细胞DHFR和TrxR活性。因此，这项研究提供了令人信服的证据，表明14和15可以通过在细胞水平上进行多靶点抑制来发挥其抗癌作用。

  In this study, 30 chalcone derivatives containing [1,2,4]-triazole-[4,3-a]-pyridine were designed and synthesized. The results of antibacterial activity showed that EC50 values of N26 against Xoo, Pcb was 36.41, 38.53 μg/mL, respectively, which were better than those of thiodiazole copper, whose EC50 values were 60.62, 106.75 μg/mL, respectively. The bacterial inhibitory activity of N26 against Xoo

  本研究设计并合成了30种含[1,2,4]-三唑-[4,3-a]-吡啶的查耳酮衍生物。抗菌活性结果表明， N26对Xoo 、 Pcb的EC 50值分别为36.41、38.53 μg/mL，优于噻二唑铜的EC 50值分别为60.62、106.75 μg/mL。通过SEM验证了N26对Xoo的细菌抑制活性。初步探讨了N26与Xoo的抗菌机制，实验结果表明，当药物浓度为100 mg/L时， N26对Xoo具有良好的细胞膜通透性，可抑制EPS含量和胞外酶含量的产生，从而破坏Xoo的细胞膜通透性。 Xoo生物膜的完整性达到抑制Xoo的效果。 N26在200mg/L时对马铃薯采后体内病斑具有保护和抑制作用。采用半叶干斑法测定N1 - N30抗TMV活性。 N22的治疗活性和保护活性的EC 50值分别为77.64和81.55 μg/mL，优于NNM（分别为294.27、175.88 μg/mL）。 MST

  In this paper, a series of phenoxypyridine-containing chalcone derivatives (L1–L28) were designed and synthesized, characterized on NMR and HRMS. Ningnanmycin (NNM) was used as a control agent. The results of the antiviral activity testing showed that the curative activity EC50 values of L1 and L4 against TMV were 140.5 and 90.7 μg/mL, respectively, which were superior to that of NNM (148.3 μg/mL)
