Description

DSM265 is a long-duration inhibitor of P. falciparum dihydroorotate dehydrogenase (PfDHODH) with an IC50 of 8.9 nM. DSM265 can also inhibit the growth of Pf3D7 parasites with an EC50 of 4.3 nM[1][2].

In Vivo

DSM265 (0.5 to 75 mg/kg; Oral administration; twice daily; for 4 days; NOD-scid IL-2Rγnull (NSG) mice) has potent in vivo antimalarial activity with 90% effective dose (ED90) of 3 mg/kg per day (1.5 mg/kg twice daily). The maximum rate of parasite killing occurred at and above a dose of 13 mg/kg per day (6.4 mg/kg twice daily).
DSM265 has moderate terminal elimination half-life (t1/2) of 2-4 hours for mice (0.5 to 75 mg/kg, oral) [2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.75 mg/mL (6.62 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.75 mg/mL (6.62 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
