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: ≥ 2.5 mg/mL (5.65 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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)

Protocol
BI 224436 is dissolved in acetonitrile-methanol (50:50, vol/vol) to achieve a concentration of 1.5 mM. Phosphate buffer (pH 7.4), cofactor, and test substance or isoform-selective inhibitors are added to 96-well plates and are prewarmed to 37°C for 10 min. Cofactor concentrations are 1.3 mM NADP, 3.3 mM glucose-6-phosphate, and 0.4 U/mL glucose-6-phosphate dehydrogenase. Reactions are initiated by the addition of prewarmed (37°C) enzyme and substrate. Reaction mixtures are incubated at 37°C and terminated by the addition of 0.038 ml of 40:40:20 (vol/vol) methanol–acetonitrile–0.5 M Tris buffer. Formation of the fluorescent metabolites is measured using a microplate spectrofluorometer at specific excitation and emission wavelengths. The IC50 is determined using the 96-well 32 procedure supplied with the SAS software[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Rats: For oral PK studies, BI 224436 is administered in a suspension of 0.5% (wt/vol) methyl cellulose (MC), 0.3% (vol/vol) Tween 80, and 1% (vol/vol) N-methyl-2-pyrrolidine (MP) in water. For i.v. dosing, BI 224436 is dissolved in 70% PEG 400–30% water (vol/vol). The appropriate amount of BI 224436 is dissolved in PEG 400 with sonication. The rats receive a single i.v. dose of 0.2 mg/kg of body weight (1 mL/kg) via the jugular vein as a bolus or received a single oral dose of 0.4 mg/kg (10 mL/kg) administered by gavage. Blood samples are obtained at 0, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, and 32 h after dosing for analysis[1].
