DSM502 shows inhibitory activity against P. falciparum DHODH (PfDHODH, IC50=20 nM), P. vivax DHODH (PvDHODH, IC50=14 nM) and Pf3D7 cells (EC50=14 nM), with no inhibition of the human enzyme[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
DSM502 (18.3 and 50 mg/kg; a single p.o.) exhibits high oral bioavailability (>100%, >100%), apparent t1/2 (2.6, 3.6 h) and Cmax (8.4, 42.3 μM) in mice[1].
DSM502 (2.8 mg/kg; a single i.v.) exhibits apparent t1/2 (2.8 h), plasma clearance (26.1 mL/min/kg), and Vss (1.2 L/kg) in mice[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:SCID mice (23-36 g) were inoculated with parasites[1]
-
Dosage:10 and 50 mg/kg
-
Administration:P.o. once daily for 4 days starting on day 3 after mice had been inoculated with parasites
-
Result:Resulted in 97% parasite clearance compared to 85% clearance in the GSK study.
The 10 mg/kg mouse died on day 5.

Solvente y solubilidad
DMSO : 250 mg/mL (773.25 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (6.43 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
Please enter your animal formula composition:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
