Affinity Chromatography: A Historical Perspective, David S. Hage, Ryan E. Matsuda Jan 2015

Affinity Chromatography: A Historical Perspective, David S. Hage, Ryan E. Matsuda

David Hage Publications

Affinity chromatography is one of the most selective and versatile forms of liquid chromatography for the separation or analysis of chemicals in complex mixtures. This method makes use of a biologically related agent as the stationary phase, which provides an affinity column with the ability to bind selectively and reversibly to a given target in a sample. This review examines the early work in this method and various developments that have lead to the current status of this technique. The general principles of affinity chromatography are briefly described as part of this discussion. Past and recent efforts in the generation …


Chromatographic Immunoassays: Strategies And Recent Developments In The Analysis Of Drugs And Biological Agents, Ryan E. Matsuda, Elliott Rodriguez, Doddavenkatanna Suresh, David S. Hage Jan 2015

Chromatographic Immunoassays: Strategies And Recent Developments In The Analysis Of Drugs And Biological Agents, Ryan E. Matsuda, Elliott Rodriguez, Doddavenkatanna Suresh, David S. Hage

David Hage Publications

A chromatographic immunoassay is a technique in which an antibody or antibodyrelated agent is used as part of a chromatographic system for the isolation or measurement of a specific target. Various binding agents, detection methods, supports and assay formats have been developed for this group of methods, and applications have been reported that range from drugs, hormones and herbicides to peptides, proteins and bacteria. This review discusses the general principles and applications of chromatographic immunoassays, with an emphasis being given to methods and formats that have been developed for the analysis of drugs and biological agents. The relative advantages or …


Predicting Aqueous Solubility Of Pharmaceutical Agents By Solid Dispersion Prepared By Solvent Evaporation Method, Karthik Reddy Patlolla Jan 2015

Predicting Aqueous Solubility Of Pharmaceutical Agents By Solid Dispersion Prepared By Solvent Evaporation Method, Karthik Reddy Patlolla

University of the Pacific Theses and Dissertations

Solubility of active pharmaceutical agents is a crucial process that determines drug absorption and ultimately its bioavailability. Many of the new therapeutically beneficial compounds discovered are lipophilic requiring various solubility enhancement strategies to improve their solubility. Among these strategies, solubility enhancement using solid dispersions is a leading method. To obtain a desirable increase in the solubility of a poorly-soluble compound, a good understanding of the molecular descriptors influencing the enhancement of solubility is essential. Therefore, the major research objective was to determine the descriptors which significantly influence the solubility enhancement by solid dispersions. After enhancing the solubility of selected poorly-soluble …


Physicochemical And Structural Analysis Of Polymers As Putative Drugs, Meghan L. Thompson Jan 2015

Physicochemical And Structural Analysis Of Polymers As Putative Drugs, Meghan L. Thompson

Theses and Dissertations

Sulfated low molecular weight lignins (LMWLs) have shown good activity as anticoagulants by allosterically inhibiting thrombin, as well as promising agents for treating emphysema through inhibition of elastolysis, oxidation, and inflammation. Sulfated LMWLs are chemo-enzymatically synthesized from starting monomers caffeic, ferulic, and sinapic acid into sulfated dehydropolymers known as CDS, FDS, and SDS. To further the LMWLs’ development as drugs, their structural composition and physicochemical characteristics were defined in this work. The molecular weight distribution profile of the sulfated LMWLs from size exclusion chromatography performed on a high pressure liquid chromatography system (SEC-HPLC) changed from bimodal when no surfactant is …
