"The Power of Ion Mobility-Mass Spectrometry for Structural Characterization and Conformational Analyses of Therapeutic Drugs" 

Therapeutic drug (mAb) is the largest class of biomolecule-based drugs in the pharmaceutical industry. The production and analysis of these drugs are quite difficult due to their complex chemical structures. They have many variants of the same protein due to variable post-translational modifications depends to the production media. Mainly separation techniques coupled mass spectrometry and direct infusion mass spectrometric techniques were used for the detailed therapeutic drug analysis in their intact form and after reduction process using various enzymes and reducing agents. Following these analyses techniques tandem mass spectrometry was used due to analyze the posttranslational modifications and the amino acid sequences changing during the drug productions. In addition, conformational analyzes of therapeutic drugs are carried out using ion mobility technique combined mass spectrometry (IM-MS) based on the separation of ions in the gas phase according to their collision cross-section (CCS) values as a size parameter1. In this way, fast and straightforward configured systems were applied to perform full therapeutic drug analyses in their intact form without using any additional separation techniques prior to mass spectrometric analysis. Using IM-MS exactly same masses but different configurations of biomolecules and their fragments could be differentiated from each other effectively. In this study some denaturing agent and specific enzymes were used to define the therapeutic drug fragments using mainly ion mobility-mass spectrometric techniques. Immune globulin G and Bevacizumab therapeutic drug was used as model drug and ion mobility-mass spectrometric technique was used for analysis intact form also digested form of therapeutic drugs. It could be noted that IM-MS had capability to obtain advanced analysis in a short time for therapeutic drugs.
