  Effect of Flavonol Derivatives on the Carrageenin-Induced Paw Edema in the Rat and Inhibition of Cyclooxygenase-1 and 5-Lipoxygenasein Vitro

  摘要：

  Alkoxyflavonols were synthesized by the Algar-Flynn-Oyamada (AFO) cyclization of chalcones. Hydroxyflavonols were prepared by dealkylation of methoxyflavonols by refluxing in hydroiodic acid. The alkoxyflavonols 3-hydroxy-2-(2,3,4-trimethoxyphenyl)-4H-chromen-4-one (6), 2-(4-ethoxyphenyl)-3-hydroxy-4H-chromen-4-one (7), 2-(4-butoxyphenyl)-3-hydroxy-4H-chromen-4-one (10), and 2-(3-n-butoxyphenyl)-3-hydroxy-4H-chromen-4-one (11) as well as the trihydroxy derivative 3-hydroxy-2-(3,4,5-trihydroxyphenyl)-4H-chromen-4-one (18) displayed high anti-inflammatory activity in carrageenin-induced rat paw edema. Additionally, the inhibition of enzymes of the arachidonic acid cascade by the derivatives was investigated in vitro. In contrast to the natural compound quercetin, the compounds were more potent inhibiting cyclooxygenase-1 than 5-lipoxygenase except for 3-hydroxy-7-methoxy-2-(4-methoxyphenyl)-4H-chromen-4-one (5). No correlation between the anti-inflammatory activity in the rat paw edema test and the inhibition of 5-lipoxygenase or cyclooxygenase-1 could be observed. In conclusion, the present results suggest that other effects than inhibition of these enzymes of the arachidonic acid cascade are important for the anti-inflammatory activity of the investigated alkoxyflavonols.

  通过调节MicroRNA的生物合成作为Pin1抑制剂抑制肝细胞癌的prenylated黄酮醇衍生物的发现。

  摘要：

  肽脯氨酰顺-反异构酶中Pin1在人类癌症的发展至关重要的作用。最近，我们披露了Pin1调节miRNA的生物发生，miRNA在HCC中异常表达并促进HCC进展，表明Pin1在HCC治疗中的治疗作用。在此，7-（苄氧基）-3,5-二羟基-2-（4-甲氧基苯基）-8-（3-甲基丁-2-烯-1-基）-4H-铬-4--1（AF-39）被鉴定为新型的Pin1抑制剂。生化试验表明，AF-39有效抑制中Pin1活性，其IC 50的1.008μ值米，并且还显示中肽基脯氨酰异构酶对中Pin1高选择性。此外，AF‐39以剂量和时间依赖性方式显着抑制HCC细胞的细胞增殖。从机制上讲，AF-39调节XPO5的亚细胞分布并增加HCC细胞中miRNA的生物发生。这项工作为HCC治疗提供了有希望的先导化合物，突出了基于miRNA的疗法对人类癌症的治疗潜力。

  Inosine 5′‐monophosphate dehydrogenase (IMPDH) catalyzes a crucial step in the biosynthesis of guanine nucleotides. Being a validated target for immunosuppressive, antiviral, and anticancer drug development, lately it has been exploited as a promising target for antimicrobial therapy. Extending our previous work on Mycobacterium tuberculosis IMPDH, GuaB2, inhibitor development, we screened a set of

  肌苷5'-单磷酸脱氢酶（IMPDH）催化鸟嘌呤核苷酸生物合成中的关键步骤。作为免疫抑制，抗病毒和抗癌药物开发的有效靶标，最近它已被用作抗菌治疗的有希望的靶标。扩展了我们先前关于结核分枝杆菌IMPDH，GuaB2，抑制剂开发的工作，我们筛选了23种新的化学实体（NCE），它们被取代的黄酮（系列1）和1,2,3-三唑（系列2）核心结构所取代。体外幽门螺杆菌IMPDH（Hp IMPDH）和人IMPDH2（h IMPDH2）的抑制活性。所有NCE都具有可接受的分子，物理化学和毒性特性。的范围在10μM浓度下，Hp IMPDH和h IMPDH2的抑制分别为9–99.9％和16–57％。最有效的Hp IMPDH抑制剂25c的IC 50值为1.27μM ，无h IMPDH2抑制活性。中等强度，结构新颖的命中分子25c可作为进一步设计和开发高效Hp IMPDH抑制剂的先导。

  Flavonoids are polyphenolic compounds which display an array of biological activities and are considered potential antitumor agents. Here we evaluated the antiproliferative activity of selected synthetic flavonoids against human leukemia cell lines. We found that 4′-bromoflavonol (flavonol 3) was the most potent. This compound inhibited proliferation in a concentration-dependent manner, induced apoptosis
