EMD638683 is an orally active SGK1 inhibitor with an IC₅₀ of 3 μM. EMD638683 exhibits strong inhibition against SGK1, moderate inhibition against SGK2 and SGK3, and shows excellent selectivity for other AGC kinase family members. EMD638683 has antihypertensive activity by inhibiting SGK1, and independently of the blood pressure-lowering effect, it effectively prevents heart inflammation and fibrosis caused by hypertension by inhibiting the cardiac NLRP3 inflammation body/ IL-1β axis. EMD638683 promotes apoptosis of colon cancer cells and sensitizes radiotherapy. EMD638683 (S-Form) can be used in research related to hypertension, hypertensive heart damage, and colon cancer.

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.
