Description
InformationVidofludimus Vidofludimus (SC12267, 4SC-101) is an orally active and potent dihydroorotate dehydrogenase (DHODH) inhibitor with IC50 of 134 nM for human DHODH. Vidofludimus calcium (IMU-838) is investigated as a potential treatment option for COVID-19. Phase 2.TargetsHuman DHODH 134 nMIn vitroVidofludimus causes a concentration dependent inhibition of phytohemagglutinin-stimulated PBMC proliferation via the inhibition of pyrimidine de novo synthesis. Vidofludimus attenuates IL-17 secretion from colonic strips by inhibition of STAT3 and NF-κB activation.In vivoIn MRLlpr/lpr mice, Vidofludimus (300 mg/kg, p.o.) reduces systemic autoimmunity and improves Lupus Nephritis. In Rats, Vidofludimus (60 mg/kg, p.o.) effectively reduces macroscopic and histological pathology and the numbers of CD3+ T cells. In a rat model of renal transplantation, Vidofludimus (20 mg/kg, p.o.) prolongs survival, paralleled by amelioration of histologic signs of acute rejection.Cell Research(from reference)Cell lines：PBMCs Incubation Time：48 h
