  Synthesis of novel flavone hydrazones: In-vitro evaluation of α-glucosidase inhibition, QSAR analysis and docking studies

  摘要：

  Thirty derivatives of flavone hydrazone (5-34) had been synthesized through a five-step reaction and screened for their a-glucosidase inhibition activity. Chalcone 1 was synthesized through aldol condensation then subjected through oxidative cyclization, esterification, and condensation reaction to afford the final products. The result for baker's yeast alpha-glucosidase (EC 3.2.1.20) inhibition assay showed that all compounds are active with reference to the IC50 value of the acarbose (standard drug) except for compound 3. Increase in activity observed for compounds 2 to 34 clearly highlights the importance of flavone, hydrazide and hydrazone linkage in suppressing the activity of a-glucosidase. Additional functional group on N-benzylidene moiety further enhances the activity significantly. Compound 5 (15.4 +/- 0.22 mu M), a 2,4,6-trihydroxy substituted compound, is the most active compound in the series. Other compounds which were found to be active are those having chlorine, fluorine, and nitro substituents. Compounds with methoxy, pyridine, and methyl substituents are weakly active. Further studies showed that they are not active in inhibiting histone deacetylase activity and do not possess any cytotoxic properties. QSAR model was being developed to further identify the structural requirements contributing to the activity. Using Discovery Studio (DS) 2.5, various 2D descriptors were being used to develop the model. The QSAR model is able to predict the pIC(50) and could be used as a prediction tool for compounds having the same skeletal framework. Molecular docking was done for all compounds using homology model of alpha-glucosidase to identify important binding modes responsible for inhibition activity. (C) 2015 Elsevier Masson SAS.

  新型查耳酮连接的 5-苯基-3-异恶唑羧酸甲酯的合成及构效关系对耐药结核分枝杆菌具有潜在活性

  摘要：

  为了寻找对新出现的耐药结核分枝杆菌有效的新型治疗剂并应对现有药物的长期治疗方案，我们在此介绍了一系列新的 5-苯基-3-异恶唑羧酸甲酯-查耳酮杂化物的合成和生物学评价. 在 35 种合成化合物中，32 种类似物显示出对结核分枝杆菌H37Rv 的有效体外活性，MIC 为 0.12–16 μg/mL。针对 Vero 细胞的细胞活力测试表明 29 种化合物无细胞毒性（CC 50  > 20 μg/mL & SI > 10）。大多数 MIC 为 0.12 μg/mL（7 b、7j、7 ab）的有效化合物的选择性指数 (SI) 超过 320。 进一步研究抗药性结核分枝杆菌显示 7j 是最有效的化合物，MIC 为 0.03–0.5 μg/mL。时间杀伤动力学研究表明，化合物 7j 显示出浓度依赖性杀菌活性，其效力与目前的一线抗结核药物相当。综上所述，7j 呈现出一种新的热门产品，有可能被转化为一种有效的抗分枝杆菌。

  The reaction of bis(chalcones) 1a−d and bis(chalcone) tetrabromo derivatives 3a−d with hydrazine hydrate gave bis(pyrazolines) 4a−d and bis(pyrazoles) 5a−d, respectively. Bis(pyrazoles) 5e,f bearing hydroxyphenyl substituents have been prepared from the reaction of bis(chromones) 6c,d with hydrazine hydrate, because their synthesis from the corresponding benzyloxy-substituted 5c,d gave very poor yields

  双（查耳酮）1a-d 和双（查耳酮）四溴衍生物 3a-d 与水合肼的反应分别得到双（吡唑啉）4a-d 和双（吡唑）5a-d。带有羟基苯基取代基的双(吡唑) 5e,f 已由双(色酮) 6c,d 与水合肼的反应制备，因为它们由相应的苄氧基取代的5c,d 合成的产率非常低。所有新化合物的结构都已通过广泛的 NMR 光谱研究确定。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
• A chalcone derivative binds a putative allosteric site of YopH: Inhibition of a virulence factor of Yersinia

  Identification of allosteric inhibitors of PTPs has attracted great interest as a new strategy to overcome the challenge of discover potent and selective molecules for therapeutic intervention. YopH is a virulence factor of the genus Yersinia , validated as an antimicrobial target. The finding of a second substrate binding site in YopH has revealed a putative allosteric site that could be further exploited. Novel chalcone compounds that inhibit PTPs activity were designed and synthesized. Compound 3j was the most potent inhibitor, interestingly, with different mechanisms of inhibition for the panel of enzymes evaluated. Further, our results showed that com- pound 3j is an irreversible non-competitive inhibitor of YopH that binds to a site different than the catalytic site, but close to the well-known second binding site of YopH.

  Novel chalcones were found as potent inhibitors of interleukin (IL)-5. 1-(2-Benzyloxy-6-hydroxyphenyl)-3-(4-hydroxyphenyl)-2-propen-1-one (2b, 78.8% inhibition at 50 mu M, IC50 = 25.3 mu M) was initially identified as a potent inhibitor of IL-5. This shows the compatible activity with budesonide or sophoricoside. To identify structural requirements, 26 chalcones were prepared and their inhibitory activities were tested against IL-5. Among them, compound 4-[(E)-3-(2-cyclohexylmethoxy-6-hydroxyphenyl)-3-oxoprop-1-enyl]benzenesulfonamide (2w, 99.5% inhibition at 50 mu M, IC50 = 1-8 mu M) shows the most potent activity. The important structural requirements of these chalcone analogs exhibiting the inhibitory activity against IL-5 were recognized as the following. (1) The hydrophobic group such as benzyloxy or cyclohexylmethoxy at 6-position of A ring is necessary. (2) The existence of phenolic hydroxyl at 6-position of A ring is critical. (3) Propenone unit as alpha,beta-unsaturated ketone is essential. (4) Electron withdrawing groups with hydrogen acceptor property at 4-position of B ring enhance the activity and quantitative structure-activity relationship of 2 regarding these substituents was determined.
