    3,4-Dihydroxychalcones as potent 5-lipoxygenase and cyclooxygenase inhibitors
    摘要:
    A novel series of 3,4-dihydroxychalcones was synthesized to evaluate their effects against 5-lipoxygenase and cyclooxygenase. Almost all compounds exhibited potent inhibitory effects on 5-lipoxygenase with antioxidative effects, and some also inhibited cyclooxygenase. The 2',5'-disubstituted 3,4-dihydroxychalcones with hydroxy or alkoxy groups exhibited optimal inhibition of cyclooxygenase. We found that 2',5'-dimethoxy-3,4-dihydroxychalcone (37; HX-0836) inhibited cyclooxygenase to the same degree as flufenamic acid and 6-lipoxygenase, more than quercetin. Finally, these active inhibitors of 5-lipoxygenase inhibited arachidonic acid-induced mouse ear edema more than phenidone.

When evaluated in vivo, 8 and 208 were comparable to chloroquine in extending the lifespan of infected mice. Multivariate data analysis showed that in vitro activity was mainly determined by the properties of ring B. Quantitative structure-activity relationship models with satisfactory predictive

    Abstract

    Eleven chalcone derivatives have been tested for their inhibitory effects on platelet aggregation in rabbit platelet suspension and the activation of mast cells and neutrophils.

    Arachidonic acid-induced platelet aggregation was potently inhibited by almost all the compounds and some also had a potent inhibitory effect on collagen-induced platelet aggregation and cyclooxygenase. Some hydroxychalcone derivatives showed strong inhibitory effects on the release of β-glucuronidase and lysozyme, and on superoxide formation by rat neutrophils stimulated with the peptide fMet-Leu-Phe (fMLP). We found that the anti-inflammatory effect of 2′,5′-dihydroxychalcone was greater than that of trifluoperazine. 2′,5′-Dihydroxy and 2′,3,4,4′-tetrahydroxyl chalcones, even at low concentration (50 μm), tested in platelet-rich plasma from man almost completely inhibited secondary aggregation induced by adrenaline.

    These results suggest that the anti-platelet effects of the chalcones are mainly a result of inhibition of thromboxane formation.

    摘要:对十一种查尔酮衍生物进行了测试,以评估它们对兔血小板悬液中血小板聚集、肥大细胞和中性粒细胞激活的抑制作用。花生四烯酸诱导的血小板聚集几乎被所有化合物强烈抑制,有些化合物对胶原诱导的血小板聚集和环氧化酶也有强烈的抑制作用。一些羟基查尔酮衍生物显示出对β-葡萄糖苷酸酶和溶菌酶释放,以及对受到fMet-Leu-Phe(fMLP)肽激活的大鼠中性粒细胞产生的超氧化物的强烈抑制作用。我们发现,2′,5′-二羟基查尔酮的抗炎效果大于三氟她嗪。即使在低浓度(50 μm)下,在人体富含血小板的血浆中,2′,5′-二羟基和2′,3,4,4′-四羟基查尔酮几乎完全抑制了由肾上腺素诱导的继发性聚集。这些结果表明,查尔酮的抗血小板作用主要是通过抑制血栓素形成实现的。

    Gram-positive bacteria are the most common cause of skin infection in hospitalized patients, with Staphylococcus aureus being the principal pathogen responsible for deaths. A series of poly-oxygenated chalcones was synthesized and assayed for anti-staphylococcal activity. Hydroxylated chalcones were more effective in the inhibition of microbial growth than methoxylated analogues. The compound 3’,5’,4-trihydroxychalcone is the most promising compound among those evaluated, showing a much broader antimicrobial spectrum than oxacillin and a MIC of 64 µg/ml to a multidrug- resistant hospital clinical strain of S. aureus.

    2‐anthryl‐chromone derivatives against AChE significantly decreased, while that of 2‐biphenyl chromone derivatives with 7‐substituted tertiary amine side chain is better than relative flavones derivatives. For all new synthesized compounds, the position of tertiary amine side chain obviously influenced the activity of inhibiting AChE. The results above provide great worthy information for the further development
    在这项研究中,设计、合成了一系列含有6或7个取代叔胺侧链的新型黄酮(2-苯基色酮)、2-萘基色酮、2-蒽基色酮或2-联苯色酮衍生物,并评估乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE)抑制。结果表明,色酮支架上连接的芳环的改变对生物活性产生显着影响。与黄酮类化合物相比,2-萘基色酮、2-蒽基色酮衍生物对AChE的抑制活性显着降低,而带有7位取代叔胺侧链的2-联苯色酮衍生物的抑制活性优于相关黄酮类衍生物。对于所有新合成的化合物,叔胺侧链的位置明显影响抑制AChE的活性。上述结果为新型AChE抑制剂的进一步开发提供了有价值的信息。在新合成的化合物中,化合物5a具有有效的AChE抑制作用(IC 50 = 1.29 ± 0.10 μmol/L),并且对AChE的选择性高于BChE(选择性比:27.96)。化合物5a的酶动力学研究表明它对 AChE 产生混合型抑制作用。
