Synthesis of Neuraminidase binders suitable for theranostics
Berenguer Albiñana, Carlos ; Machara, Aleš (advisor) ; Cibulka, Radek (referee) ; Soural, Miroslav (referee)
Influenza viruses cause respiratory illnesses which can vary in severity depending on the strain of the virus, as well as the age and health condition of the host. Influenza remains a major threat to public health due to its nature prone to suffer mutations. As a result, vaccines have to be reformulated annually and new strains may cause sporadic global pandemics. Furthermore, the recent emergence of resistant strains of the virus against the current standard of care (oseltamivir and zanamivir) underlines the need of novel anti-influenza therapeutics. The aim of this dissertation work is to contribute to the discovery of new anti-influenza inhibitors either by rational drug-design and optimization of oseltamivir structure, or by developing screening assays suitable for the discovery of novel inhibitors of the enzymes neuraminidase or RNA-polymerase. Scheme 1. Overview of the strategy used for the development of new anti-influenza therapeutics. The dashed arrows indicate the inhibitors that were converted into probes and their corresponding target enzymes Two main modification points were explored for the improvement of oseltamivir properties (Scheme 1); modifications at carbon C-3 aimed to overcome oseltamivir resistance caused by common mutations like H274Y, meanwhile modifications at carbon C-5...
