Coronavirus Proteases As Therapeutic Targets: Development Of Biosensors To Detect Inhibition Of Protease Activity And Separation Of The Multiple Functions Of Coronavirus Papain-Like Proteases, Andrew Kilianski
Dissertations
Coronaviruses are important human pathogens and have the potential to severely impact public health on an international scale. The emergence of SARS-CoV and MERS-CoV highlight the need for research to identify antivirals and vaccines against coronaviruses. To develop therapeutics against current and potentially emergent coronaviruses, I utilized two approaches targeting the proteases encoded within all coronaviruses. The papain-like protease and 3C-like protease of coronaviruses are responsible for cleaving viral polyproteins early during infection, and this step is required for viral replication. To quantitatively assess the inhibition by small-molecule compounds on MERS-CoV protease activity, I developed a luciferase-based biosensor to monitor …
Multifunctional Coronavirus Papain-Like Proteases As Targets For Antiviral Therapeutics And Vaccines, Anna Maria Mielech
Multifunctional Coronavirus Papain-Like Proteases As Targets For Antiviral Therapeutics And Vaccines, Anna Maria Mielech
Dissertations
Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and Middle Ease Respiratory Syndrome coronavirus (MERS-CoV) pose a severe threat to humans because of high mortality. Despite the risk of coronavirus (CoV) emerging in the human population there are no antiviral drugs or vaccines to combat coronavirus infection. The focus of my dissertation was to study the multifunctionality of papain-like proteases (PLPs) encoded within coronavirus genomes to facilitate the development of antiviral drugs and vaccines. The viral PLPs are critical for processing the amino-terminal end of the replicase during virus replication and are attractive targets for antiviral therapies.
In my research, I analyzed …
