Development Of Bioanalytical Methods For Clinical Applications And Drug Screening, Xiaohan Cai Jan 2011

Development Of Bioanalytical Methods For Clinical Applications And Drug Screening, Xiaohan Cai

ETD Archive

In the past decade, bioanalytical method development has become an integral part of clinical diagnosis, biomarker discovery, and drug discovery and development. The new and emerged bioanalytical technologies allow the quantitative and qualitative analysis of small molecules and biomolecules with high sensitivity and specificity. Specifically, the bioanalytical methods based on LC-MS and methylation-specific PCR are well suited for detecting low-abundance metabolites, proteins, and DNA in biofluids and tissues for biomarker investigation. They offer great clinical promises for early diseases diagnosis and therapeutic interventions. Besides, the LC-MS/MS quantitative method is essential for the estimation of pharmacokinetic and toxicological properties in drug …


Development Of Quantitative Lc-Ms/Ms Methods For The Pharmacological Studies Of Anti-Cancer Drugs, Lan Li Jan 2011

Development Of Quantitative Lc-Ms/Ms Methods For The Pharmacological Studies Of Anti-Cancer Drugs, Lan Li

ETD Archive

In the development of anti-cancer drugs, it is essential to study the pharmacological profiles of the drugs. Among the analytical tools utilized in the pharmacological studies, LC-MS/MS has gained increased popularity due to its unequivocal sensitivity and specificity, as well as the ability of handling a wide variety of compounds with relatively simple sample preparation procedures. In this work, a brief review on the method rational, instrumentations, analytical method validation, and work flow of the method development was included. The processes of LC-MS/MS method development for the pharmacological studies of three anti-cancer drugs (i.e., methoxyamine, fludarabine, and 6-benzylthioinosine) were illustrated. …


Capillary Gradient Chromatofocusing-Mass Spectrometry;A Sensitive Approach For Protein Analysis, James Anthony Hribar Jan 2011

Capillary Gradient Chromatofocusing-Mass Spectrometry;A Sensitive Approach For Protein Analysis, James Anthony Hribar

ETD Archive

Gradient chromatofocusing-mass spectrometry is a new technique for protein analysis recently introduced by our research group. Capable of separating and identifying proteins according to pI values and molecular weight, gradient chromatofocusing-mass spectrometry has been achieved by integrating a new ion-exchange chromatography technique called gradient chromatofocusing with a newly discovered buffer system that promotes mass spectrometry detection. Differing from traditional ion-exchange chromatography techniques, gradient chromatofocusing employs specific low molecular weight, volatile buffer components that are introduced onto an ion-exchange HPLC column by programming a binary gradient pumping system to deliver the correct proportions of acidic mobile phase to overcome buffering of …


Quantitative And Qualitative Mass Spectrometric Analysis Of Anticancer Agents, Drugs Of Abuse And Enzyme-Inhibitor Complexes, Keri M. Smith Jan 2011

Quantitative And Qualitative Mass Spectrometric Analysis Of Anticancer Agents, Drugs Of Abuse And Enzyme-Inhibitor Complexes, Keri M. Smith

ETD Archive

Mass spectrometry is a valuable tool in the analysis of many types of compounds. From small molecules to large proteins, mass spectrometry can help to interrogate samples and give insights to the origins of disease as well as calculate an exact concentration. Bioanalytical method development is an integral component in the measurement of such compounds. To facilitate proper analytical investigation, the process of method development, analysis, and interpretation must be understood. This work describes the basis and procedure for bioanalytical method development and its detailed application to preclinical studies of the antineoplastic agent hexamethylene bisacetamide and measurement ofillicit drugs of …
