GtoPdb Ligand ID: 11164

Compound class: Synthetic organic
Comment: S416 is an inhibitor of dihydroorotate dehydrogenase (DHODH) [1]. It has been explored for antiviral activity against RNA viruses, including SARS-CoV-2, based on the rationale that viruses depend on host pyrimidine synthesis to maintain their replication, and that therefore inhibiting a crucial step in this synthetic pathway should limit viral replication. Mechanistically, S416 binds at the putative ubiquinone binding tunnel within the DHODH active site.
