L. 杂志全名:Progress in Lipid Research 年份,卷(期): 起止页码: 2006, Vol 45, No 2, 160-186 英文摘要: Eukaryotic algae are a very diverse group of organisms which inhabit a huge range of ecosystems from the Antarctic to deserts. They account for over half the primary productivity at the base of the food chain. In recent years studies on the lipid biochemistry of algae has shifted from experiments with a few model organisms to encompass a much larger number of, often unusual, algae. This has led to the discovery of new compounds, including major membrane components, as well as the elucidation of lipid signalling pathways. A major drive in recent research have been attempts to discover genes that code for expression of the various proteins involved in the production of very long-chain polyunsaturated fatty acids such as arachidonic, eicosapentaenoic and docosahexaenoic acids. Such work is described here together with information about how environmental factors, such as light, temperature or minerals, can change algal lipid metabolism and how adaptation may take place. 中文译文: 真核藻类中脂类及其代谢研究综述 真核藻类是一大类具有多样性的种群,它的覆盖范围很广的,栖息地遍及从南极圈到沙漠的各类生态系统。藻类占据了初级生产力的一半以上,成为食物链的基础。近年来,人们对藻细胞中脂类物质的生化研究已经从很少的几种模式微生物其他物种拓展,开展了对众多物种包括一些非常见藻类的研究。这些研究带来了许多新的化合物的发现,包括一些细胞膜的主要组分、以及脂类信号转导途径中的重要分子。这些研究的主要目标是寻找这些长链不饱和脂肪酸合成蛋白的编码基因。同时本文中还综述了环境因子(例如光、温度、微量元素)对藻类脂肪代谢的影响以及藻细胞的应答机制的相关研究信息。 影响因子(2005) 8.810 -------------------------------------------------------------------------------- 全文连接 and lipid metabolism in eukaryotic algae.part1.rar (250.0k) -------------------------------------------------------------------------------- 全文连接-2 and lipid metabolism in eukaryotic algae.part2.rar (106.03k) -------------------------------------------------------------------------------- 共翻译了5篇,其中三篇综述,两篇研究性文章。都是有关海洋药物方面的,大部分是海洋抗癌药物。尽我所能进行了翻译,部分词汇查不到中文译名,就没有翻译。 个人认为第四篇文章的水平很高,这时发表在PNAS上面的文章,一般化学类的文章,JACS(影响因子7左右)是顶级的杂志了。做的是海洋复杂天然产物的构型构象确定,该化合物是一个含侧链的25元环的大环内酯。类似于沙海葵毒素,研究方法也是从结构的片断开始,逐步确定其立体结构,当然本文所研究的结构没有沙海葵毒素(由129个碳原子组成的聚醚化合物,分子量为2677,含有40个羟基和8个甲基)那么复杂。虽然本文没有确定整个结构的立体结构,但本文的研究为确定该类型化合物的立体结构打下了基础。 第一篇(文章类型:Review) 文题:Marine pharmacology in 2003–2004: Anti-tumour and cytotoxic compounds 作者:Alejandro M.S. Mayer, Kirk R. Gustafson 杂志全名:European Journal of Cancer(IF for 2005:3.706;IF for 2005:3.302) 年份,卷(期): 起止页码:42 (2006 ):2241-2270 英文摘要:During 2003 and 2004, marine pharmacology research directed towards the discovery and development of novel anti-tumour agents was published in 163 peer-reviewed articles. The purpose of this reviewis to present a structured assessment of the anti-tumour and cytotoxic properties of 150 marine natural products, many of which are novel compounds that belong to diverse structural classes, including polyketides, terpenes, steroids and peptides. The organisms yielding these bioactive marine compounds include invertebrate animals, algae, fungi and bacteria. Anti-tumour pharmacological studies were conducted with 31 structurally defined marine natural products in a number of experimental and clinical models that further defined their mechanisms of action. Particularly potent in vitro cytotoxicity data generated with murine and human tumour cell lines was reported for 119 novel marine chemicals with as yet undetermined mechanisms of action. Noteworthy is the fact that marine anti-cancer research was sustained by a global collaborative effort, involving researchers from Australia, Austria, Canada, China, Egypt, France, Germany, Italy, Japan, Mexico, the Netherlands, New Zealand, Papua New Guinea, the Philippines, South Africa, South Korea, Spain, Switzerland, Taiwan, Thailand and the United States of America (USA). Finally, this 2003–2004 overview of the marinepharmacology literature highlights the fact that the discovery of novel marine anti-tumour agents continued at the same pace as during 1998–2002. 中文译文(包括题目): 2003-2004海洋药理学:抗肿瘤及细胞毒化合物 2003至2004年度,研究方向为寻找发现新抗肿瘤药物的海洋药理学论文总共发表了163篇。 本综述旨在对大约150个海洋天然产物的抗肿瘤及细胞毒活性进行化学结构上的分析,其中许多化合物属于不同的结构类型,包括聚酮化合物、帖类、甾体以及多肽。产生这些活性化合物的生物包括无脊椎动物、海藻、真菌和细菌。在大量的实验及临床模型上,研究人员对31个结构明确的海洋天然产物进行了抗肿瘤药理研究,这样的研究进一步明确了其作用机制。据报道,共有119种新的海洋化合物在体外对鼠或人类肿瘤细胞有特别强的细胞毒作用,作用机制尚未阐明。值得注意的是,全球许多国家合作进行海洋抗肿瘤药物研究,包括澳大利亚、奥地利、加拿大、埃及、法国、德国、意大利、日本、墨西哥、荷兰、新西兰、新几内亚、菲律宾、南非、南朝鲜、西班牙、瑞士、台湾、泰国及美国。最后,2003-2004年的海洋药理学研究综述表明发现新抗肿瘤化合物的速度与1998-2002期间一致。 第二篇(文章类型:Review) 文题:Indole alkaloid marine natural products: An established source of cancer drug leads with considerable promise for the control of parasitic, neurological and other diseases 作者:Waseem Gul, Mark T.

Luke Simmons, Eric Andrianasolo, Kerry McPhail, Patricia Flatt, and William H. Gerwick 杂志全名:Molecular Cancer Therapeutics(IF for 2005:5.171;IF for 2004:5.242) 年份,卷(期): 起止页码:2005;4(2):333–42 英文摘要:The chemical and biological diversity of the marine environment is immeasurable and therefore is an extraordinary resource for the discovery of new anticancer drugs. Recent technological and methodologic advances in structure elucidation, organic synthesis, and biological assay have resulted in the isolation and clinical evaluation of various novel anticancer agents. These compounds range in structural class from simple linear peptides, such as dolastatin 10, to complex macrocyclic polyethers, such as halichondrin B; equally as diverse are the molecular modes of action by which these molecules impart their biological activity. This review highlights several marine natural products and their synthetic derivatives that are currently undergoing clinical evaluation as anticancer drugs. 中文译文(包括题目): 作为抗肿瘤药物的海洋天然产物 海洋环境的化学与生物多样性是无法衡量的,因此海洋是发现新抗癌药物的特别资源库。今年来,结构鉴定、有机合成、生物分析在技术及方法学方面的发展带动了各种新抗癌药物的分离及临床评价。这些化合物的结构各异,从简单的线性多肽如多拉司他汀10,到复杂的大环聚醚类化合物如软海绵素B。有如结构差异,这些化合物赖以传递作用的分子模式也各不相同。本文综述了一些来自海洋的天然产物及其合成衍生物,目前这些化合物正作为抗癌药进行临床评价。 第四篇(文章类型:research article) 文题:Synthesis of antimicrofilament marine macrolides: Synthesis and configurational assignment of a C5–C16 degradation fragment of reidispongiolide A 作者:Ian Paterson, Robert Britton, Kate Ashton, Henner Knust, and Jonathan Stafford 杂志全名:proceedings of the national academy of sciences of the united states of america 年份,卷(期): 起止页码:2004 August 17; 101(33): 11986–11991. 英文摘要:Reidispongiolide A is a representative member of the sphinxolide/reidispongiolide group of cytotoxic 26-membered macrolides of marine origin. By interacting with actin in the cell cytoskeleton, the reidispongiolides and sphinxolides are potent microfilament destabilizing agents that represent a promising mechanism of action for developing novel anticancer drugs. An aldol-based synthesis of a library of diastereomers of C8–C16 and C5–C16 fragments and detailed NMR comparison with a reported degradation fragment enabled a configurational assignment for a major part of the reidispongiolide macrocyclic core, thus setting a solid foundation for ongoing synthetic efforts. 中文译文(包括题目): 具抗微丝活性的海洋大环内酯合成:reidispongiolide A分解片断C5–C16的合成及构象指定 Reidispongiolide A是来自海洋的含sphinxolide/reidispongiolide 基团的26元环大环内酯类化合物的代表。通过与细胞骨架的肌动蛋白相互作用,这些大环内酯类化合物使得微丝失稳,这是研发新抗癌药物的有望机制。从丁间醇醛开始,合成了C8-C16及C5–C16的非对映体库,并将其NMR数据与一已报道的分解片断进行详细的比较,从而指定了reidispongiolide大环母核主要部分的构象,为后续的合成工作提供了坚实的基础。 第五篇(文章类型:research article) 文题:Aureoverticillactam, a novel 22-atom macrocyclic lactam from the marine actinomycete Streptomyces aureoverticillatus. 作者:Scott S.

Using extensive MS, UV, and NMR spectral analyses, the structure has been established as compound 1, aureoverticillactam, a 22-atom macrocyclic lactam incorporating both triene and tetraene conjugated olefins. 中文译文(包括题目): 由海洋放线菌Streptomyces aureoverticillatus产生的22元环大环内酰胺Aureoverticillactam 在试图从海洋微生物中筛选得到新抗癌药物的过程中,我们发现一株分离自海洋沉积物的链酶菌属放线菌aureoverticillatus (NPS001583) 能产生一种新的大环内酰胺,其对数种不同的肿瘤细胞都有细胞毒作用。运用包括质谱、紫外及核磁共振的多种光谱分析,解析确定了该化合物1(aureoverticillactam)的结构,是一个含有共轭三烯和共轭四烯的22元环大环内酰胺。 如果你英语水平可以的话,可以直接到 (美国专利网)找找。《外文文献信息检索》PPT版(包括:外文图书信息检索、外文期刊论文检索、外文报纸检索),如有需要再联系我。
