| Description | DSM421 (DSM-421) is a dihydrodehydrogenase inhibitor (DHODH) that is in preclinical development as a potential treatment option for malaria and has shown activity against field isolates of both P. falciparum and P. vivax. |
| In vivo | DSM421, a dihydroorotate dehydrogenase inhibitor, was in preclinical development as a potential treatment option for malaria. When tested in a core battery of safety pharmacology assays, DSM421 did not produce any effects at oral doses up to 750 mg/kg in an Irwin test in rats, but a respiratory study in rats using head-out plethysmography resulted in substantial changes in respiratory function as well as moribundity and mortality at that and lower doses.[1] |
