Compound class: Synthetic organic
Comment: S312 is an inhibitor of dihydroorotate dehydrogenase (DHODH) [2]. It was initially designed and reported for application as an anti-inflammatory agent [1] and was effective in a mouse rheumatoid arthritis model. S312 has most recently been explored for antiviral activity against RNA viruses, including influenza virus strains, Zika and Ebola viruses and SARS-CoV-2, based on the rationale that viruses depend on host pyrimidine synthesis to maintain their replication rate, and that therefore inhibiting a crucial step in this synthetic pathway has potential to limit viral replication. Mechanistically, S312 binds at the putative ubiquinone binding tunnel within the DHODH active site.
