Biological Activity
IC50: 0.015 μM (PfKRS), 0.13 μM (CpKRS)[1]
LysRs-IN-2 is active against whole-cell bloodstream P. falciparum 3D7 (EC50=0.27 μM), HsKRS (IC50=1.8 μM), HepG2 cells (EC50=49 μM), and Cryptosporidium parvum (EC50=2.5 µM)[1].

Animal Model:Murine P. falciparum NODscidIL2Rγnull (SCID) model[1]
-
Dosage:1.5 mg/kg
-
Administration:Orally once a day for 4 days
-
Result:Reduced parasitemia by 90% in the malaria SCID mouse model.
-
Animal Model:NOD SCID gamma and INF-γ–knockout mouse models (Cryptosporidium mouse models)[1]
-
Dosage:20 mg/kg
-
Administration:Orally once a day for 7 days
-
Result:Reduced parasite shedding below detection level, and this reduction was sustained for 3 wk after treatment had stopped in INF-γ-knockout mice. Dosed orally at a concentration of 20 mg/kg once a day for 7 days showed 96% reduction of parasite shedding comparable to paromomycin in NOD SCID gamma mice.

Solvent & Solubility
DMSO : ≥ 60 mg/mL (168.87 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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 (stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (5.85 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 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.5 mg/mL (4.22 mM); Clear solution
This protocol yields a clear solution of ≥ 1.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (15.0 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.
