Immunopharmacology Comments |
Dihydroorotate dehydrogenase (DHODH) is the fourth, and rate-limiting enzyme in the de novo pyrimidine nucleosides biosynthetic pathway. Resting lymphocytes satisfy their pyrimidine requirements through a DHODH-independent salvage pathway, but the enzyme's expression is selectively upregulated in proliferating and activated lymphocytes, making it a target susceptible to pharmacological inhibition in activated immune cells. Inhibition of DHODH causes a reduction in the available pyrimidine pool, which leads to metabolic stress and apoptosis in highly activated cells. DHODH inhibitors are used clinically to treat autoimmune diseases such as rheumatoid arthritis or multiple sclerosis (leflunomide and teriflunomide respectively) [9]. Vidofludimus was a Phase 2 clinical candidate for IBD and RA, but has been superceded by IMU-838 which is an orally active polymorph of vidofludimus calcium (PubChem CID: 56944639) that is under evaluation for clinical efficacy in ulcerative colitis (NCT03341962), primary sclerosing cholangitis (NCT03722576) and multiple sclerosis (NCT03846219) [8]. |

General Comments |
Dihydroorotate dehydrogenase (DHODH) is the fourth enzyme in the de novo pyrimidine nucleosides biosynthetic pathway. DHODH inhibitors are used clinically to treat autoimmune diseases such as rheumatoid arthritis or multiple sclerosis (leflunomide and teriflunomide respectively) and have been investigated in oncology, virology, and parasitology (e.g. malaria) [9]. More information about P. falciparum DHODH (gene symbol PF3D7_0603300 for P. falciparum strain 3D7) as an antimalarial drug target is contained in our evolving Antimalarial targets family. DHODH has also been proposed as a host enzyme whose inhibition could have antiviral effects [15], based on evidence which confirms that viruses are highly dependent on host pyrimidine synthesis for the supply of RNA precursors that they rely on for replication. Several DHODH inhibitors have reported anti-SARS-CoV-2 activity [14], and the combination of these with drugs that inhibit the viral RNA-dependent RNA polymerase (e.g. molnupiravir and remdesivir) have demonstrated synergistic/additive antiviral activity in mice [14]. PTC Therapeutics are taking their DHODH inhibitor PTC299 forward in hospitalised COVID-19 patients (phase 2/3 NCT04439071). |
