  • 2′,5′-Dihydroxychalcone as a Potent Chemical Mediator and Cyclooxygenase Inhibitor

    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。

    in vitro incubation with chalcones 1 and 3. In a mouse model of schistosomiasis, the oral treatment (400 mg/kg) with chalcone 1 or 3 significantly caused a total worm burden reduction in mice. Chalcone 1 showed significant inhibition of the S. mansoni ATP diphosphohydrolase activity, which was corroborated by molecular docking studies. The results suggested that chalcones could be explored as lead
    在这项研究中,我们评估了查耳酮对曼氏血吸虫蠕虫的体外和体内血吸虫杀灭活性。体外试验表明查耳酮 1 和 3 是活性最强的化合物,对哺乳动物细胞没有显着影响。共聚焦激光扫描显微镜和扫描电子显微镜研究表明,与查耳酮 1 和 3 体外孵育后,曼氏血吸虫的外皮结节数量和形态学改变减少。在血吸虫病小鼠模型中,口服治疗(400 毫克) /kg) 与查耳酮 1 或 3 显着降低小鼠的总蠕虫负担。查耳酮 1 显示出对曼氏链球菌 ATP 二磷酸水解酶活性的显着抑制,分子对接研究证实了这一点。

  • Synthesis and evaluation of 2′,4′,6′-trihydroxychalcones as a new class of tyrosinase inhibitors
    作者:Nishida Jun、Gao Hong、Kawabata Jun
    DOI:10.1016/j.bmc.2007.01.017
    日期:2007.3
    In this study, we synthesized a series of hydroxychalcones and examined their tyrosinase inhibitory activity. The results showed that 2',4',6'-trihydroxychalcone (1), 2,2',3,4',6'-pentahydroxychalcone (4), 2',3,4,4,5,6'-hexahydroxychalcone (5), 2',4',6'-trihydroxy- 3,4-dimethoxychalcone (9) and 2,2,4,4',6'-pentahydroxychalcone (15) exhibited high inhibitory effects on tyrosinase with respect to L-tyrosine as a substrate. By the structure activity relationship study, it was suggested that the 2',4',6'-trihydroxyl substructure in the chalcone skeleton were efficacious for the inhibition of tyrosinase activity. And also, the catechol structure on B-ring of chalcones was not advantageous for the inhibitory potency. Furthermore, 15 (IC50 = 1 mu M) was found to show the highest activity out of a set of 15 hydroxychalcones, even better than both 2,2',4,4'-tetrahydroxychalcone (13, IC50 = 5 mu M) and kojic acid (16, IC50 = 12 mu M), which were known as potent tyrosinase inhibitors. Kinetic study revealed that 15 acts as a competitive inhibitor of tyrosinase with K-i value of 3.1 mu M. (c) 2007 Elsevier Ltd. All rights reserved.
