Research Initiation Awards provide support for junior and mid-career faculty at Historically Black Colleges and Universities who are building new research programs or redirecting and rebuilding existing research programs. It is expected that the award will further the faculty member's research capability and effectiveness, improve research and teaching at his home institution, and involve undergraduate students in research experiences. The goal of the project is to develop a new generation of agents for the control of microorganisms. This may lead to the development of novel microbial control strategies leading to the development of new techniques and protocols with applications in engineering as well as the physical, biological, medical and pharmaceutical sciences. This project will enhance the research experience and training of undergraduate students at Howard University. Additionally, it will produce knowledge, tools, and applications that will: help sustain existing scientific and educational efforts at Howard University; be integrated into existing courses; and help develop new courses with an interdisciplinary focus.This project seeks to identify and characterize small-molecule inhibitors of the bacterial phosphoenolpyruvate-carbohydrate phosphotransferease system (PTS). The studies specifically aim to measure specificity and potency of candidate compounds to inhibit PTS activity; to evaluate the broad-spectrum inhibition of biofilm formation by candidate compounds; and to establish the mechanism of action of selected candidate compounds. Given the connection between PTS activity and biofilm formation, this project hypothesizes that the identification of small-molecule modulators of the PTS will reveal new tools and approaches to regulate biofilm formation by interfering with microbial metabolic functions. Identification of novel interactions between chemical structures and targets will result from this project.

研究启动奖为历史上黑人学院和大学的初级和中级职业教师提供支持，他们正在建立新的研究项目或重新定向和重建现有的研究项目。预计该奖项将进一步教师的研究能力和有效性，提高研究和教学在他的家乡机构，并参与本科生的研究经验。 该项目的目标是开发新一代微生物控制剂。这可能会导致开发新的微生物控制策略，从而导致开发新的技术和协议，应用于工程以及物理，生物，医学和制药科学。该项目将增强霍华德大学本科生的研究经验和培训。此外，它将产生的知识，工具和应用程序，将：帮助维持现有的科学和教育工作在霍华德大学;被整合到现有的课程;并帮助开发新的课程与跨学科focus.This项目旨在确定和表征小分子抑制剂的细菌磷酸烯醇化-碳水化合物磷酸转移酶系统（PTS）。这些研究的具体目的是测量候选化合物抑制PTS活性的特异性和效力;评价候选化合物对生物膜形成的广谱抑制;以及建立所选候选化合物的作用机制。鉴于PTS活性和生物膜形成之间的联系，该项目假设鉴定PTS的小分子调节剂将揭示通过干扰微生物代谢功能来调节生物膜形成的新工具和方法。化学结构和目标之间的新的相互作用的识别将导致从这个项目。
