ABSTRACT The goal of this CETR is to use a combination of innovative strategies to combat drug resistant infectious diseases. In particular, we will use cutting edge methods in metabolomics and genomics to discover lead small molecules targeting the most problematic multi-drug resistant (MDR) Gram-negative bacterial and fungal pathogens. This project, Project 2 (P2), will develop and implement a metabolomics pipeline that will also serve Project 1 and Project 3. We will integrate bioassay data from multiple pathogens exhibiting diverse drug resistant phenotypes to supplement our metabolomics data. Essentially, we will employ metabolomics-driven pipeline to identify novel molecules with target efficacy both in vitro and in vivo againswhile also lacking host toxicity traits. To identify and access chemical diversities that will drive this project, we will target symbiotic microbes associated with i) marine invertebrates, and ii) insects; in all cases a particular focus will be placed on rare bacterial genera. Additionally, we seek answers to basic questions underpinning these new strategies and their high success rates relative to historical discovery approaches. To answer these questions and discover the next generation of antimicrobials, projects P1, P2 and P3 share three identical specific aims; Aims 1-3 all focus on how symbioses provide novel bacteria as sources for new compound discovery with in vivo efficacy against MDR pathogens. Support for this project will be supplied by four scientific cores (Chemistry, In Vitro, In Vivo, and Mechanism of Action). The outcome of this project will be novel antimicrobial small molecule leads with in vivo efficacy against MDR pathogens and host safety.

摘要 该CETR的目标是使用创新策略的组合来对抗耐药感染性疾病。 疾病特别是，我们将使用代谢组学和基因组学的尖端方法来发现铅 靶向最有问题的多重耐药（MDR）革兰氏阴性细菌的小分子， 真菌病原体该项目，项目2（P2），将开发和实施代谢组学管道， 还将服务于项目1和项目3。我们将整合来自多种病原体的生物测定数据， 不同的耐药表型来补充我们的代谢组学数据。基本上，我们将雇用 代谢组学驱动的管道，以识别具有体外和体内靶向功效的新型分子 再次，同时也缺乏宿主毒性特征。为了识别和获取化学物质， 项目，我们将针对共生微生物与i）海洋无脊椎动物，和ii）昆虫;在所有 在某些情况下，将特别关注稀有细菌属。此外，我们寻求基本的答案， 这些新策略的基础问题及其相对于历史发现的高成功率 接近。为了回答这些问题并发现下一代抗菌剂，项目P1， P2和P3有三个相同的具体目标;目标1-3都集中在共生体如何提供新型细菌 作为发现具有体内抗MDR病原体功效的新化合物的来源。支持这一 该项目将由四个科学核心（化学，体外，体内和作用机制）提供。 该项目的成果将是新型抗菌小分子先导物，其体内有效性为 MDR病原体和宿主安全性。
