DESCRIPTION (provided by applicant): Assembly of proteins, drug interactions, and substrate recognition are a few of the vital physiological interactions that depend on the chiral orientation of molecules. Preliminary results clearly demonstrate that by modifying the drift gas with chiral molecules, ion mobility spectrometry can provide a novel and rapid separation technique for chiral compounds. Similar to chiral chromatography and capillary electrophoresis, the ability of chiral ion mobility spectrometry to examine enantiomeric mixtures is based upon the interaction of analytes with neutral chiral modifiers. The ultimate goal of the research proposed is to develop and commercialize the rapid chiral separation and characterization instrument: electrospray ionization - chiral ion mobility spectrometer - mass spectrometer (ESI-CIMS-MS). The proposed system can not only separate chiral molecules in milliseconds, but also reduce method development time to minutes. Great separation speed and easy method development of ESI-CIMS-MS make it the method of choice for many applications analysis time is a critical consideration. The proposed system can be used to directly measure enantiomeric excess of chiral ingredients in pharmaceutical products, may serve to increase throughput for chirality measurements in drug discovery when hundreds of drug compounds are being screened as drug candidates, can be used to monitor the performance of preparative chiral separation processes, or can be used as a chiral selective detector for chromatographic systems. Key words: chiral Ion mobility spectrometer, electrospray ionization, enantiomers, pharmaceuticls, rapid chiral separation PUBLIC HEALTH RELEVANCE: Proposed chiral ion mobility spectrometer - mass spectrometer, separating and identifying chiral compounds in seconds, can potentially replace chiral chromatography for chiral analysis time is a critical consideration. Rapid enantiomeric excess measurement is essential in drug discovery process and QA/QC of pharmaceutical products as worldwide sales of single-enantiomer compounds made into the pharmaceutical formulations reaches $150 billion/year. The proposed system can also be used for the analysis of chiral compounds in complex mixture for quantification and detection of biomarkers, metabolites and other bioactive compounds in biomedical research.

描述（由申请人提供）：蛋白质的组装，药物相互作用和底物识别是依赖于分子手性取向的一些重要的生理相互作用。初步结果清楚地表明，通过用手性分子修饰漂移气体，离子迁移率光谱法可以为手性化合物提供一种新的快速分离技术。与手性色谱和毛细管电泳类似，手性离子迁移率光谱法检测对映体混合物的能力是基于分析物与中性手性改性剂的相互作用。研究的最终目标是开发和商业化快速手性分离和表征仪器：电喷雾电离-手性离子迁移谱仪-质谱仪（ESI-CIMS-MS）。该系统不仅可以在几毫秒内分离手性分子，而且可以将方法开发时间缩短到几分钟。ESI-CIMS-MS分离速度快，方法开发方便，是许多应用的首选方法，分析时间是一个重要的考虑因素。该系统可用于直接测量药品中手性成分的对映体过量，可用于增加药物发现中手性测量的吞吐量，当数百种药物化合物被筛选为候选药物时，可用于监测制备性手性分离过程的性能，或可用作色谱系统的手性选择性检测器。关键词：手性离子迁移谱仪，电喷雾电离，对映体，药物，快速手性分离
