This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Protein and lipid kinases are important transducers of cellular information. There are 500+ protein kinases and 30+ lipid kinases in the human genome. We are interested in developing chemical approaches for understanding and deciphering kinase mediated signaling pathways. The goal of this project is to develop highly selective small molecule protein and lipid kinase inhibitors. These small molecules are designed to fit in the ATP binding pocket of the kinases. We use synthetic organic chemistry coupled with structural biology (X-ray co-crystal structures) to develop these molecules. We typically use focused syntheses of five or fewer steps and make on the order of 20 candidate inhibitors per design. This work requires standard structural characterization of the intermediates and final products for publication or structural assignment purposes. Typically we need high resolution mass spectrometry of the small molecules. They are often highly structurally related, allowing for parameters to be optimized and used for a number of samples at once.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 蛋白质和脂质激酶是细胞信息的重要转换器。 人类基因组中有500多种蛋白激酶和30多种脂质激酶。 我们有兴趣开发化学方法来理解和破译激酶介导的信号通路。 该项目的目标是开发高选择性的小分子蛋白和脂质激酶抑制剂。 这些小分子被设计成适合激酶的 ATP 结合袋。 我们利用合成有机化学与结构生物学（X 射线共晶结构）相结合来开发这些分子。 我们通常使用五个或更少步骤的集中合成，并在每个设计中制作大约 20 个候选抑制剂。 这项工作需要中间体和最终产品的标准结构表征，以用于出版或结构分配的目的。 通常我们需要对小分子进行高分辨率质谱分析。 它们通常在结构上高度相关，允许优化参数并同时用于多个样本。
