  2. 1. Chiral Separation of Amines by Non-Aqueous Capillary Electrophoresis using Low Molecular Weight Selectors

    Author : Ylva Hedeland; Curt Pettersson; Ulf Bondesson; Lars Blomberg; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Pharmaceutical chemistry; Chiral Separation; Non-Aqueous Capillary Electrophoresis; Enantioresolution; Electro-osmotic Flow; Pharmaceuticals; Enantiomeric Amines; Low Molecular Weight Selector; Farmaceutisk kemi; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Abstract : Three chiral selectors (diketogulonic acid, benzoxycarbonylglycylproline and ketopinic acid) have been introduced for enantioseparation of pharmacologically active amines in non-aqueous capillary electrophoresis. The use of organic solvents, instead of aqueous buffers in the background electrolyte facilitated ion-pair formation between the analytes and the chiral selectors. READ MORE

  4. 2. Analytical Quality by Design Method Development for Vaccine Characterization

    Author : Lars Geurink; Catharina Sänger van de Griend; Mikael Hedeland; Martijn Schenning; Iulia Oita; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; viral vaccines; adenovirus; influenza; polio; COVID; corona; capillary electrophoresis; analytical quality by design; analytical method development; CGE; icIEF; CZE; crude cell suspension analysis; in-process sample analysis; quality control testing; biopharmaceutical characterization; Analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Abstract : Vaccines that are safe, efficacious, and can be rapidly developed are needed to prevent and to react to emerging global infectious disease threats such as influenza, Polio, and Coronavirus diseases. Fast and reliable analytical methods are required without delay to support vaccine process and product development, characterization, and quality control testing. READ MORE

  5. 3. Development of analytical methods for the determination of the small molecule component of complex biological systems

    Author : Kristian Pirttilä; Mikael Hedeland; Curt Pettersson; Torbjörn Arvidsson; Thomas Moritz; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; metabolomics; data processing; peak characterization; algorithm; multivariate data analysis; chromatography; sequential columns; HILIC; RPLC; liquid chromatography; mass spectrometry; LC; MS; noise-induced hearing loss; NIHL; guinea pig; perilymph; method development; validation; R; C ; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Abstract : The research field of untargeted metabolomics aims to determine the relative abundance of all small metabolites in a biological system in order to find biomarkers or make biological inference with regards to the internal or external stimuli. This is no trivial aim, as the small metabolites are both vast in numbers and extremely diverse in their chemical properties. READ MORE

  6. 4. Microextraction by packed sorbent of drugs and peptides in biological fluids

    Author : Seyed Mosayeb Daryanavard; Mohamed Abdel-Rehim; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; MEPS; Local anaesthetics drugs; Peptides; Analytical Chemistry; analytisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Abstract : Sample preparation as the first step in an analytical procedure has an important role, particularly in bioanalysis, because of the complexity of biological samples (blood plasma and urine). Biological matrix such as plasma and blood contains proteins, organic and inorganic salts, acids, bases and various organic compounds with similar chemistry to the analytes of interest. READ MORE

  7. 5. Development of LC-MS/MS Methods for the Analysis of Chiral and Achiral Pharmaceuticals and Metabolites in Aqueous Environmental Matrices

    Author : Victoria K.H. Barclay; Curt Pettersson; Monika Johansson; Niklas Tyrefors; Mohamed Abdel-Rehim; Uppsala universitet; []

    Abstract : This thesis describes the development of liquid chromatography tandem mass spectrometry (LC-MS/MS) methods for the trace analysis of active pharmaceutical ingredients (APIs) and their metabolites in aqueous environmental matrices. The research was focused on the development of chiral LC-MS/MS methods for the analysis of fluoxetine and metoprolol, as well as their chiral metabolites in environmental water samples. READ MORE
