Descripciòn

WHI-P97 is a potent and selective JAK-3 inhibitor. WHI-P97 is effective in preventing the development allergic asthma in vivo^[1].

IC₅₀ & Target^[1]

Cellular Effect

Cell Line	Type	Value	Description	References
RBL-2H3	IC₅₀	6.8 μM Compound: WHI-P97	Inhibition of IgE receptor/FcERI mediated leukotriene release from rat RBL-2H3 cells Inhibition of IgE receptor/FcERI mediated leukotriene release from rat RBL-2H3 cells	[PMID: 12565956]

In Vitro

WHI-P97 inhibits the translocation of 5-lipoxygenase (5-LO) from the nucleoplasm to the nuclear membrane and consequently 5-LO-dependent leukotriene (LT) synthesis after IgE receptor/FcεRI crosslinking by >90% at low micromolar concentrations^[1].
WHI-P97 (30 μM) stantially reduces the IgE/antigen-induced LTC4 release from mast cells^[1].

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

In Vivo

WHI-P97 is very well tolerated in mice, with no signs of toxicity at dose levels ranging from 5 μg/kg to 50 mg/kg, and LD₁₀ is not reached at a 50 mg/kg dose level when administered as a single i.p. or i.v. bolus dose^[1].
WHI-P97 (i.v. injection; 40 mg/kg; single dose) has an elimination half-life (t_1/2) of 58.9 min and systemic clearance (CL) of 891 ml/h/kg in CD-1 mice and a t_1/2 of 84.2 min and CL of 1513 ml/h/kg in BALB/c mice. The values for AUC and C_max are 107.3 μM and 296.7 μM, respectively, in CD-1 mice. And the IC₅₀ values are 58.4 μM and 212.7 μM, respectively, in BALB/c mice. The large volume of distribution are 322 ml/kg in CD-1 mice and 415 ml/kg in BALB/c mice^[1].
WHI-P97 (intraperitoneal injection; 40 mg/kg; 24 days) prevents ovalbumin-sensitized mice the development of airway hyper-responsiveness to methacholine in a dose-dependent fashion in mice. WHI-P97 inhibits the eosinophil recruitment to the airway lumen after the ovalbumin challenge in a dose-dependent fashion^[1].

Stock Solution Working Solution

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: ≥ 0.59 mg/mL (1.30 mM); Clear solution

This protocol yields a clear solution of ≥ 0.59 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.9 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.

Protocol 2

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

Solubility: ≥ 0.59 mg/mL (1.30 mM); Clear solution

This protocol yields a clear solution of ≥ 0.59 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 (5.9 mg/mL) to 900 μL Corn oil, and mix evenly.

Working Solution

For the following dissolution methods, please prepare the working solution directly:

It is recommended to prepare fresh solutions and use them promptly within a short period of time.

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: 50% PEG300 50% Saline

Solubility: 8 mg/mL (17.58 mM); Suspended solution; Need ultrasonic

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
