Talmapimod (SCIO-469) is an orally active and selective inhibitor of p38α MAPK with an IC₅₀ of 9 nM. Talmapimod inhibits the secretion of inflammatory factors (such as TNFα, IL-1β, IL-6, and VEGF) by suppressing the p38α MAPK pathway, and it also inhibits angiogenesis and osteoclast activation. Talmapimod inhibits the growth of multiple myeloma cells and induces apoptosis. Talmapimod can be used to study various hematological malignancies (such as multiple myeloma, myelodysplastic syndrome).

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.

Help & FAQs

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.
