Description

KP496 is a selective, dual antagonist for Leukotriene D4 receptor and Thromboxane A2 receptor.

IC50 & Target[1]

LTD4

 

TXA2 Receptor

 

In Vivo

KP496 significantly inhibits acute (day 7) and chronic (day 21) lung inflammation. KP496 attenuates the number of lymphocytes on day 7 and those of macrophages, neutrophils, and eosinophils on days 7 and 21. KP496 and prednisolone significantly suppress the increase of hydroxyl-L-proline content in the lung. Compare to respective vehicle control group, the inhibition ratio of KP496 and prednisolone for increase of hydroxyl-L-proline content is about 74 and 63%, respectively[1]. The KP496 (100 mg/head) group and prednisolone (10 mg/kg) group exhibit significant inhibition of numbers of infiltrating total cells, eosinophils, monocytes/macrophages, and lymphocytes compare with the control group. Infiltration of all types of cells except neutrophils is decreased in the KP496 (30m g/head) group, though not to significant extents[2].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (3.61 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.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (3.61 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 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 (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Animal Administration
[1]

Male mice (9 weeks old, 33 to 42g are used) BLM solution (15 mg/mL) is intravenously injected into mice (0.1 mL/10 g of body weight) on day 0. Mice are sacrificed on day 7 or 21. They are exposed to an aerosol of KP496 (KP-496) solution (0.5%) for 30 min using a pressure nebulizer 1 h before and 3 h after BLM-injection on day 0. From day 1 to the day before sacrificed, mice are exposed to KP496 (0.5%) for 30 min morning and evening[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
