Periodic Reporting for period 1 - MS4Drug (An Innovative Mass Spectrometry-Based Workflow for Drug Discovery)
Berichtszeitraum: 2019-07-01 bis 2021-06-30
Several bioanalytical methods have been developed to address this question. Recently chemical cross-linking in combination with mass spectrometry (XLMS) demonstrated to be very powerful when added to the toolbox of those protein structural methods.
The aim of this project was to introduce cross-linking mass spectrometry (XLMS) in the pipeline of drug discovery of a pharma company and integrate it with the preexisting approaches to study protein structure and dynamics. In fact, the combination of several techniques provides complementary and robust data.
This project contributed to decipher the effect of drug candidates on the structure of several protein targets for different diseases and, more generally, to advance the XLMS approach into a routine method for drug discovery.
This has been one of the first application of the XLMS approach in the field of structural biology in Italy.
Those protocols have been applied and optimized on several enzyme and protein targets. The disclosure and publication of the details of those protocols and the results of our experiments will be delayed until patenting, following the Chiesi Intellectual Property procedures.
The fundamental principles of the structural proteomics methodologies applied along the project have been reviewed in Current Opinion in Biotechnology: Iacobucci C., Götze M., Sinz A. (2020). Cross-linking/mass spectrometry to get a closer view on protein interaction networks. Current opinion in biotechnology, 63, 48-53.
