项目摘要

Core D – Structural and Computational Virology ABSTRACT Core D aims to characterize the structure and dynamics of viral protein targets in complex with small molecule and nanobody inhibitors, in support of all Projects within the Midwest AViDD Center. Structural characterization of viral targets in complex with inhibitors provides a valuable framework for the rational design and modification of small molecules as they advance from the initial hit stage, through lead optimization, and beyond. Structure and dynamics of these co-complexes also informs on mechanism of action. In Core D, we assemble a collaborative team of world experts to provide comprehensive descriptions of structures and dynamics of targets of interest. We will employ x-ray crystallography, cryoelectron microscopy, and NMR spectroscopy to provide experimental characterization. Subsequently, computational biophysical techniques, including all-atom molecular dynamics simulations, computational solvent mapping, and other methods will be used to create accurate models of the targets in vivo (e.g., with any mutations from experiment reverted to wild type, addition of N- and O-linked glycans and other post-translational modifications) and explore target dynamics under relevant physiological conditions. Altogether, our collective efforts will provide informative insights into the structure and dynamics of Midwest AViDD Center targets, and accelerate the discovery and design of new and safer medications.

核心 D – 结构和计算病毒学抽象的 Core D 旨在表征与小分子复合的病毒蛋白靶标的结构和动态和纳米抗体抑制剂，支持中西部 AViDD 结构表征中心的所有项目。病毒靶点与抑制剂的复合物为合理设计和修饰提供了有价值的框架小分子从最初的命中阶段发展到先导化合物优化等阶段。这些复合物的动态也揭示了作用机制。在 Core D 中，我们组装了一个。由世界专家组成的协作团队提供结构和动态的全面描述我们将利用 X 射线晶体学、冷冻电子显微镜和核磁共振波谱来分析感兴趣的目标。随后，提供计算生物物理技术，包括全原子。分子动力学模拟、计算溶剂图和其他方法将用于创建体内目标的准确模型（例如，将实验中的任何突变恢复为野生型，另外 N-和O-连接聚糖和其他翻译后修饰）并探索目标动力学总而言之，我们的集体努力将为了解相关的生理条件提供信息。中西部 AViDD 中心目标的结构和动态，并加速新的和更安全的药物。
