海洋天然产物化学是化学和生物学的边缘学科,是天然有机化学的一个重要领域。自从1964年河豚毒素(tetrodotoxin)的结构被阐明后,化学家们对这个学科产生了极大的兴趣,并且积极地开展了研究工作,对更多的海洋生物进行了新化合物的探讨。七十年代以来,由于有了分离复杂混合物的研究工具和对很少量物质的结构进行快速测定的现代化仪器,海洋天然产物化学才得到迅速的发展。海洋天然产物化学主要是研究海洋天然产物的二级代谢物,碳水化合物、氨基酸及其聚合物被认为是有生命物质的成分,即一级代谢物,则是生物化学研究的领域。 相似文献

Synthesis of biologically active compounds, including natural products and pharmaceutical agents, is an important and interesting research area since the large structural diversity and complexity of bioactive compounds make them an important source of leads and scaffolds in drug discovery and development. Many structurally and also biologically interesting compounds, including marine natural products, have been isolated from nature and have also been prepared on the basis of a computational design for the purpose of developing medicinal chemistry. In order to obtain a wide variety of derivatives of biologically active compounds from the viewpoint of medicinal chemistry, it is essential to establish efficient synthetic procedures for desired targets. Newly developed reactions should also be used for efficient synthesis of desired compounds. Thus, recent progress in the synthesis of biologically active compounds by focusing on the development of new reactions is summarized in this review article. 相似文献

Highlights of marine natural products chemistry (1972-1999) 总被引:10,自引:0,他引:10

Marine Natural Products Chemistry is essentially a child of the 1970's that developed rapidly during the 1980's and matured in the last decade. With a few notable exceptions, it is difficult to select individual papers that significantly impacted the field. However, marine natural products chemistry has often influenced other fields and that aspect is the focus of this review. It is clear that the early directions taken by marine natural products chemists drew as much from the examples provided by insect chemical ecology as from the longer history of phytochemistry. By 1975 there were already three parallel tracks in marine natural products chemistry: marine toxins, marine biomedicinals and marine chemical ecology. It is the integration of the three fields of study that has given marine natural products chemistry its unique character and vigour. 相似文献

Marine invertebrates have been reported to be an excellent resource of many novel bioactive compounds. Studies reported that Indonesia has remarkable yet underexplored marine natural products, with a high chemical diversity and a broad spectrum of biological activities. This review discusses recent updates on the exploration of marine natural products from Indonesian marine invertebrates (i.e., sponges, tunicates, and soft corals) throughout 2007–2020. This paper summarizes the structural diversity and biological function of the bioactive compounds isolated from Indonesian marine invertebrates as antimicrobial, antifungal, anticancer, and antiviral, while also presenting the opportunity for further investigation of novel compounds derived from Indonesian marine invertebrates. 相似文献

Covering: 1972 to 2011. This review covers the literature of prenylated quinone, hydroquinone and naphthoquinone marine natural products with reported cytotoxic and/or antioxidant properties. The structures, biological activity and, where applicable, the syntheses of 159 cytotoxic/antioxidant compounds, isolated from various marine organisms, are presented, while trends in the distribution of these cytotoxic metabolites, across the different marine phyla, are highlighted. Marine prenylated quinones, hydroquinones and naphthoquinones are of mixed polyketide and terpenoid biogenesis and recent biosynthetic studies of selected compounds are discussed. 相似文献

The proteasome regulates diverse intracellular processes, including cell-cycle progression, cell adhesion and migration, apoptosis and antigen presentation: selective inhibitors of the proteasome, therefore, have great therapeutic potential for the treatment of cancer. TMC-95A–D are unique natural products and represent a new class of noncovalent, reversible, and selective proteasome inhibitors with exceptionally strong bioactivity profiles and interesting structural properties. Significant recent advances in the syntheses of these natural products have led to intense interest in the development of related compounds as potential anticancer agents: the chemistry and biology of these natural products and analogues will be described in this review article. 相似文献
