DESCRIPTION (provided by applicant): The long term objective of this research program is to use cell-specific cytotoxic natural products as vehicles to advance the fields of complex molecule synthesis and drug discovery. These goals will require an interdisciplinary approach to define the mechanistic basis by which these natural products selectively target cancer cells using the tools of chemical biology, relying primarily upon the power of chemical synthesis. As such, contributions from our laboratory will focus on the development of efficient and stereocontrolled strategies for the synthesis of complex natural products and their respective congeners of interest. Collaborative efforts will allow us to develop SAR profiles that will ultimately lead to identification of the cellular target for the secondary metabolites that we intend to study. Specific Aims for the forthcoming grant period include: (1) Chemical synthesis azido apoptolidinone; (2) Development of procedures for the enzymatic glycosylation of the unnatural aglycones using precursor directed biosynthesis in collaboration with Professor Brian Bachmann (Vanderbilt Institute of Chemical Biology); (3) Stereocontrolled synthesis of ammocidin, a polyketide derived natural product that selectively induces apoptosis in ras-dependent cells; (4) Identification of the cellular target(s) of apoptolidin and hibarimicin E using a chemical proteomics strategy in collaboration with Professors Dan Liebler and Larry Marnett (Vanderbilt Institute of Chemical Biology); (5) Chemical synthesis of hibarimicinone and the hibarimicin shunt metabolite HMP-Y1. Lay language description: One long term objective is to develop methods for the assembly of a group of natural products that have proven to selectively eliminate cancer cells without harming normal cells. A second objective is to use various chemical and biochemical tools to understand, at a molecular level, how these compounds target cancer cells. Advances in this area could have significant impact in the treatment of cancer.

描述(申请人提供)：该研究计划的长期目标是利用细胞特异性细胞毒性天然产物作为载体，推动复杂分子合成和药物发现领域的发展。这些目标将需要一种跨学科的方法来确定这些天然产品主要依靠化学合成的力量，利用化学生物学工具选择性地针对癌细胞的机制基础。因此，我们实验室的贡献将集中在开发高效和立体控制的策略，以合成复杂的天然产品及其各自感兴趣的同系物。合作的努力将使我们能够开发合成孔径雷达图谱，最终将导致识别我们打算研究的次生代谢物的细胞靶标。即将到来的资助期的具体目标包括：(1)化学合成叠氮凋亡素；(2)与Brian Bachmann教授(Vanderbilt化学生物学研究所)合作，开发酶促糖基化非天然苷元的程序；(3)立体控制合成氨基杀菌素，这是一种聚酮衍生的天然产物，可选择性地诱导依赖ras的细胞凋亡；(4)与Dan Liebler教授和Larry Marnett教授(Vanderbilt化学生物研究所)合作，利用化学蛋白质组学技术鉴定凋亡素和组霉素E的细胞靶点(S)；(5)化学合成巴里米松和组米星代谢产物HMP-Y1。外行语言描述：一个长期目标是开发一组天然产品的组装方法，这些天然产品已被证明可以选择性地消除癌细胞，而不会损害正常细胞。第二个目标是使用各种化学和生化工具在分子水平上了解这些化合物是如何针对癌细胞的。这一领域的进展可能会对癌症的治疗产生重大影响。
