Ordering Information

Biological Activity

BAY 2402234 (Orludodstat) is a potent, selective dihydroorotate dehydrogenase (DHODH) inhibitor with an IC50 of. By blocking DHODH activity within the mitochondrial inner membrane, it disrupts the de novo pyrimidine biosynthesis pathway, causing depletion of intracellular pyrimidine pools. This metabolic inhibition induces cell differentiation, suppresses cell proliferation, and triggers apoptosis in myeloid leukemia cells, effectively impairing tumor growth in preclinical models. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
