  • 毒性总结
鉴定和使用:胡椒醛是一种固体。它用于香水、调味品和有机合成。是香草和樱桃风味的成分。它也被用于治疗头虱。人体研究:一个人摄入了十克胡椒醛,没有出现任何不良反应。动物研究:当大鼠口服13-115毫克胡椒醛5-9天时,观察到肝实质细胞脂肪浸润。每天通过胃管给予3只雄性和3只雌性大鼠900毫克/千克体重,持续4天,部分动物出现轻微的肝脏损伤。两组各20只雄性和20只雌性大鼠在含有0、0.1和0.5%胡椒醛的饮食中喂养2年,没有出现任何特定的不良反应。根据大鼠在500毫克/千克体重/天的剂量下喂养15周的研究,确定了NOAEL(无观察到不良反应水平)为500毫克/千克体重/天。胡椒醛在大肠杆菌DNA修复试验(Rec assay)中呈阳性,但未进行代谢激活,而在 Ames沙门氏菌回复突变试验或大肠杆菌WP2 uvrA回复突变试验中呈阴性。
IDENTIFICATION AND USE: Piperonal is a solid. It is used in perfumery, flavors, and organic syntheses. A constituent of vanilla and cherry flavors. It has also been used for the treatment of head lice. HUMAN STUDIES: Ten grams of piperonal were ingested by man without any adverse effect. ANIMAL STUDIES: When rats were given 13-115 mg piperonal perorally for 5-9 days, fatty infiltration of the liver parenchymal cells was noted. Intragastric administration of 900 mg/kg bw per day to 3 male and 3 female rats for 4 days produced slight gross liver damage in some animals. Groups of 20 male and 20 female rats were fed on diets containing 0, 0.1 and 0.5 % piperonal for 2 years without any specific adverse effect. Based of a feeding study in rats at 500 mg/kg bw per day for a period of 15 weeks NOAEL of 500 mg/kg bw was determined. Piperonal was positive in the Bacillus subtilis DNA-repair test (Rec assay) without metabolic activation, but it was negative when tested in the Ames Salmonella reversion assay or in the Escherichia coli WP2 uvrA reversion test.

  • 相互作用
范围:胡椒醛是一种在香草中发现的芳香化合物,具有类似香草醛的花香。本研究旨在测试胡椒醛是否减轻高脂饮食(HFD)诱导的小鼠内脏脂肪积聚,并探讨其潜在的分子机制。 方法与结果:雄性C57BL/6N小鼠被喂食正常饮食、高脂饮食或添加了0.05%胡椒醛的高脂饮食(PSD)10周。与高脂饮食组相比,PSD饮食组的小鼠体重增加、总内脏脂肪垫重量和血浆脂质水平均有所减轻。胡椒醛补充高脂饮食增加了小鼠白色脂肪组织(WAT)中某些腺苷酸环化酶(Adcy)同型和蛋白激酶A(PKA)的mRNA表达。与高脂饮食组相比,PSD饮食组小鼠的脂肪生成相关基因下调,而脂肪酸氧化和产热相关基因上调。胡椒醛通过减少其底物(ATP)的Km值,直接激活小鼠WAT准备的血浆膜中的Adcy。此外,胡椒醛在3T3-L1细胞中诱导的抑制脂肪细胞分化和提高Adcy和PKA活性的作用被Adcy抑制剂消除。 结论:胡椒醛在高脂饮食喂养的小鼠中的抗脂肪生成作用似乎与WAT中增加的Adcy-PKA信号传导有关。
SCOPE: Piperonal is an aromatic compound found in vanilla and has a floral odor resembling vanillin. This study was aimed to test whether piperonal attenuates visceral adiposity induced by a high-fat diet (HFD) in mice and to explore the underlying molecular mechanisms. METHODS AND RESULTS: Male C57BL/6N mice were fed a normal diet, HFD, or 0.05% piperonal-supplemented HFD (PSD) for 10 weeks. PSD-fed mice showed attenuation of body weight gain, total visceral fat pad weights, and plasma lipid levels compared to HFD-fed mice. Piperonal supplementation of the HFD increased the mRNA expression of certain isotypes of adenylate cyclase (Adcy) and protein kinase A (PKA) in the white adipose tissue (WAT) of mice. The adipogenesis-related genes were downregulated, whereas fatty acid oxidation- and thermogenesis-related genes were upregulated in the WAT of PSD-fed mice compared to those in HFD-fed mice. Piperonal directly activated Adcy by decreasing the Km for its substrate (ATP) in plasma membranes prepared from the WAT of mice. Furthermore, piperonal-induced inhibition of adipocyte differentiation and elevation of Adcy and PKA activities in 3T3-L1 cells were abrogated by an Adcy inhibitor. CONCLUSION: The anti-adipogenic effect of piperonal in mice fed the high-fat diet appears to be associated with increased Adcy-PKA signaling in WAT.

制备方法与用途

制备方法
  1. 以黄樟油素为原料可制取洋茉莉醛。在10份酒精中加入6份氢氧化钾,投入异构化反应釜中。搅拌并加热至回流使氢氧化钾溶解。然后在此溶液中加入6份纯黄樟油素,缓缓加热混合物使之回流,反应15~20小时。反应完毕后冷却混合物,再用水稀释,然后蒸去大部分酒精。余下的粗异黄樟油素用真空分馏的方法除去其中杂质。

在搪玻璃反应釜中,先投入26份蒸馏水、11.6份重铬酸钠和少量对氨基苯碘酸,搅拌溶解。加入6.6份异黄樟油素,在室温下搅拌混合后,一边搅拌一边缓缓加入98%的工业用硫酸。因反应放热需在夹套中通冷水冷却,并要求加硫酸的速度缓慢。硫酸加完后继续反应0.5小时后静置分层。分出苯层,余下的酸性混合物再在40℃下用8份苯再萃取一次。合并二次萃取的苯液,洗涤并中和,再将苯蒸出(回收)。蒸馏釜中留下的粗制洋茉莉醛再进行真空分馏即得半固态的洋茉莉醛。将它溶于等量95%酒精中微热使洋茉莉醛完全溶解,加适量活性炭搅拌0.5小时后过滤、冷却结晶、低温干燥,可得到纯度较高的洋茉莉醛。

  1. 烟草中的洋茉莉醛可以采用BU 14标准。合成制备方法有两种:半合成法和全合成法。半合成法是以天然黄樟油中的黄樟油素为原料,在碱性条件下异构化成为异黄樟油素,再用臭氧氧化成为洋茉莉醛;全合成法则以邻苯二酚和乙醛酸为原料进行合成。

    作者:Young Ho Seo、Sun You Park
    DOI:10.5012/bkcs.2014.35.4.1154
    日期:2014.4.20
    Hsp90 is an ubiquitous molecular chaperone protein, which plays an important role in regulating maturation and stabilization of many oncogenic proteins. Due to its potential to simultaneously disable multiple signaling pathways, Hsp90 represents great promise as a therapeutic target of cancer. In this study, we synthesized flavokawain analogues and evaluated their biological activities against drug-resistant cancer cells. The study indicated that compound 1i impaired the growth of gefitinib-resistant non-small cell lung cancer (H1975), down-regulated the expression of Hsp90 client proteins including EGFR, Her2, Met, Akt and Cdk4, and upregulated the expression of Hsp70. The result strongly suggested that compound 1i inhibited the proliferation of cancer cells through Hsp90 inhibition. Overall, compound 1i could serve as a potential lead compound to overcome the drug resistance in cancer chemotherapy.
    Hsp90是一种普遍存在的分子伴侣蛋白,在调节多种致癌蛋白的成熟和稳定中起着重要作用。由于其同时禁用多个信号通路的潜力,Hsp90作为癌症的治疗靶点具有巨大前景。在本研究中,我们合成了黄卡瓦醇类似物,并评估了它们对耐药癌细胞的生物活性。研究表明,化合物1i损害了吉非替尼耐药的非小细胞肺癌(H1975)的生长,下调了包括EGFR、Her2、Met、Akt和Cdk4在内的Hsp90客户蛋白的表达,并上调了Hsp70的表达。结果强烈表明,化合物1i通过抑制Hsp90抑制了癌细胞的增殖。总的来说,化合物1i有可能作为一种潜在的先导化合物,克服癌症化疗中的药物耐药性。

    Diversity Oriented Clicking (DOC) is a unified click‐approach for the modular synthesis of lead‐like structures through application of the wide family of click transformations. DOC evolved from the concept of achieving “diversity with ease” , by combining classic C−C π‐bond click chemistry with recent developments in connective SuFEx‐technologies. We showcase 2‐Substituted‐Alkynyl‐1‐Sulfonyl Fluorides
    面向多样性的点击 (DOC) 是一种统一的点击方法,用于通过应用广泛的点击转换家族来模块化合成类先导结构。DOC 从实现“轻松实现多样性”的概念演变而来,将经典的 C−C π 键点击化学与连接性 SuFEx 技术的最新发展相结合。我们展示了 2-取代的- A炔基-1-磺酰基F氟化物(SASFs)作为一类新的连接枢纽,与多种点击环加成过程相结合。通过具有一系列偶极子和环状二烯的 SASF 的选择性 DOC,我们以最少的合成步骤报告了 173 种独特功能分子的多样化点击库。SuFExable 库包含 10 个离散的杂环核心结构,这些核心结构源自 1,3- 和 1,5- 偶极子;而与环状二烯的反应会产生几种三维双环 Diels-Alder 加合物。通过对 96 孔板中的磺酰氟侧基进行 SuFEx 点击衍生化,可以通过后期修饰将文库增加到 278 种离散化合物——证明了 DOC 方法在快速合成不同功能结构方面的多功能性。
