Synergistic inhibition of SARS-CoV-2 replication by pyrimidine analogues and inhibitors of pyrimidine synthesis

Project leader: Prof. Dr. med. Matthias Dobbelstein

Key area

  • Antiviral strategies: agents and vaccines, antibodies

Who is involved?

  • Prof. Dr. med. Matthias Dobbelstein (Project leader, UMG)
  • Prof. Dr. Maren von Köckritz-Blickwede (TiHo)
  • Prof. Dr. Asisa Volz (TiHo)

What is the aim?

We are evaluating the combination of two pharmacological strategies against SARS-CoV-2 replication. On the one hand, we treat with molnupiravir, a cytidine analogue that is spuriously incorporated into viral RNA. On the other hand, we prevent the cells from synthesising their own pyrimidine bases by inhibiting the enzyme DHODH. The synergistic effect of these two approaches will be tested in cell and animal models to develop a treatment approach against COVID-19.
