Bio-pharmaceutical and pharmaceutical analysis. Coordinator: Bartolini

Studies on the modulation of bio-recognition phenomena, the structural alterations of pharmaceutically relevant proteins and the chirality of drugs by means of spectroscopic, spectrometric and chromatographic techniques. Development/validation of analytical methods for the quality control of drugs

Research themes

Subjects related to drug discovery and biomedical area

Studies on molecular bio-recognition phenomena and determination of the kinetic and thermodynamic binding parameters (kon, koff, KD) by surface plasmon resonance (SPR) optical biosensor, circular dichroism (CD) and fluorescence spectroscopies.

Characterization of structural alterations in proteins of pharmaceutical interest by liquid chromatography coupled to mass spectrometry (LC-MS) and CD analysis.

Development of analytical tools based on immobilized enzymes and proteins for online studies (inhibition, binding, tryptic digestion and N-deglycosylation). 

Areas of study:

Study of structural alterations of circulating serum albumin as marker in diseases characterized by high levels of oxidative stress and inflammation (cirrhosis and diabetes).

Screening of cholinesterase inhibitors and screening of inhibitors of b-amyloid and/or tau aggregation for the treatment of Alzheimer's disease. 

Investigations on the secondary structure of proteins by circular dichroism.

Subjects related to the pharmaceutical field

Development and validation of new HPLC methods for drug and nutraceutical (dietary supplements) quality control in new formulations or in commercially available products, containing active ingredients of synthetic and/or natural origin.
