Protocol	In Vitro	WHI-P97 (30 μM) stantially reduces the IgE/antigen-induced LTC4 release from mast cells. 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.
Protocol	In Vivo	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. WHI-P97 (i.v. injection; 40 mg/kg; single dose) has an elimination half-life (t1/2) of 58.9 min and systemic clearance (CL) of 891 ml/h/kg in CD-1 mice and a t1/2 of 84.2 min and CL of 1513 ml/h/kg in BALB/c mice. The values for AUC and Cmax 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. 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.

These protocols are for reference only. InvivoChem does not independently validate these methods.

Method for preparing DMSO master liquid: mg drug pre-dissolved in µL DMSO(Master liquid concentration mg/mL) ,Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.

Method for preparing in vivo formulation: Take µL DMSO master liquid, next add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH₂O,mix and clarify.

Note:

(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
