DESCRIPTION (provided by applicant): In this revised Program Project renewal application, the applicant group is representative of three primary institutions. The Ohio State University (OSU), the University of Illinois at Chicago (UIC), and the University of North Carolina at Greensboro (UNCG). The participants have combined their vast experience in the isolation, structure elucidation, and biological evaluation of natural products, to continue the development of a consolidated, integrated program for the discovery of novel anticancer agents of diverse origin for development as cancer chemotherapeutic agents. Plant materials to be studied in Project 1 (OSU) will be collected by established botanists located in tropical countries with the assistance of the NAPRALERT database (Project 2; UIC), and cyanobacteria (Project 2) and filamentous fungi (Project 3 UNCG) will also be accessed. Organisms acquired will be extracted and evaluated in a diverse battery of relevant mechanism-based, cell-based, and tumor-growth related assays currently operational at OSU (Project 1), UIC (Core A), Columbia University (through Project 3), and a new pharmaceutical company partner, Eisai Inc., Andover, MA (through Core C at OSU). Dereplication of known active compounds will be accomplished at OSU, UIC, and UNCG using computerized literature surveys and LC-MS coupled to bioassays. Bioassay-directed fractionation will be employed in Projects 1-3, for the elucidation of active principles. Lead development of active natural products via medicinal chemistry and pharmacokineticsrelated studies will be conducted at OSU (Core B), facilitated by the OSU Biostatistics group (Core C). Novel, active compounds thus discovered will be further evaluated in our panel of in vitro and in vivo bioassays (Projects 1 and 3, Cores A and Eisai). Group decisions will be made regarding the further development of agents for potential use as anticancer agents. The more advanced states of biological and toxicological testing, as well as the procurement of larger quantities of lead compounds will be sponsored by Eisai (through Core C). The Consortium will work with the involvement of the NCI Program Director in the discovery process, and plans to hold regular meetings of key scientific personnel (inclusive of our External and OSU Internal Advisory panels) to enhance communication and decision-making processes, to be organized by Core C. Excellent facilities for the isolation, structure determination, chemical modification, synthesis, and in vitro and in vivo biological evaluation, and overall project data management are available. RELEVANCE (See instructions): Cancer is responsible for about one in every four deaths in the United States, and new treatments are urgently needed. It is the overall goal of the integrated studies in this renewal application to discover novel chemicals from selected tropical rainforest plants, as well as cyanobacteria and fungi, for development as cancer chemotherapeutic agents, particularly for tumors not cured by present treatment methods.

描述（由申请人提供）：在此修订后的计划项目更新申请中，申请人群体代表三个主要机构。俄亥俄州州立大学（OSU）、伊利诺伊大学芝加哥分校（UIC）和北卡罗来纳州格林斯伯勒分校（UNCG）。参与者结合了他们在天然产物的分离，结构解析和生物学评价方面的丰富经验，继续开发一个巩固的综合计划，用于发现不同来源的新型抗癌药物，以开发为癌症化疗药物。项目1（俄勒冈州立大学）研究的植物材料将由热带国家的植物学家在NAPRALERT数据库（项目2; UIC）的帮助下收集，蓝细菌（项目2）和丝状真菌（项目3 UNCG）也将被访问。将在目前在OSU（项目1）、UIC（核心A）、哥伦比亚大学（通过项目3）和一家新的制药公司合作伙伴Jiangai Inc.运行的各种基于相关机制、基于细胞和肿瘤生长相关的试验中提取和评价获得的微生物，Andover，MA（通过OSU的Core C）。将在OSU、UIC和UNCG使用计算机化文献调查和LC-MS结合生物测定完成已知活性化合物的去复制。在项目1-3中将采用生物测定导向的分级分离，以阐明活性成分。通过药物化学和药代动力学相关研究，在OSU（核心B）进行活性天然产物的先导开发，由OSU生物统计组（核心C）协助。由此发现的新型活性化合物将在我们的体外和体内生物测定组中进一步评估（项目1和3，核心A和Riskai）。将就进一步开发可能用作抗癌药物的药物做出小组决定。生物学和毒理学试验的更高级阶段以及采购更大量的先导化合物将由生物技术研究所（通过核心C）赞助。该联盟将与NCI项目主任一起参与发现过程，并计划定期举行关键科学人员会议（包括我们的外部和OSU内部咨询小组），以加强沟通和决策过程，由核心C组织。具有优良的分离、结构测定、化学修饰、合成、体外和体内生物学评价以及整个项目数据管理的设施。 相关性（见说明）：在美国，每四例死亡中就有一例是癌症造成的，迫切需要新的治疗方法。在此更新申请中，综合研究的总体目标是从选定的热带雨林植物以及蓝细菌和真菌中发现新的化学物质，用于开发癌症化疗药物，特别是用于目前治疗方法无法治愈的肿瘤。
