Description:

WARNING: This product is for research use only, not for human or veterinary use.

DSM265 is a long-duration, potent and selective dihydroorotate dehydrogenase (DHODH) inhibitor. DSM265 is potential useful for the prevention and treatment of malaria. DSM265 is the first DHODH inhibitor to reach clinical development for treatment of malaria. DSM265 is highly selective toward DHODH of the malaria parasite Plasmodium, efficacious against both blood and liver stages of P. falciparum, and active against drug-resistant parasite isolates. DSM265 has advantages over current treatment options that are dosed daily or are inactive against the parasite liver stage.

More Info
Biological target:
DSM265 is a long-duration inhibitor of P. falciparum dihydroorotate dehydrogenase (PfDHODH) with an IC50 of 8.9 nM.
In vitro activity:
TBD
In vivo activity:
Liver parasite burden was quantified by IVIS and showed a 2.5-log reduction in liver burden (P < 0.0001) in the DSM265-treated mice compared with control mice (Figure 2, B and C). Whole livers were also harvested on day 6 to determine parasite burden using qPCR. DSM265 resulted in a 5.2-log decrease in liver stage burden (P < 0.0001) (Figure 2D). Additionally, in 3 of the 5 mice treated with DSM265, the number of Plasmodium 18S rRNA copies were below the assay limit of quantification and were completely undetectable in 1 mouse.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.

Preparing Stock Solutions

The following data is based on the product molecular weight 415.33 Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.
