Senexin A
Based on 9 publication(s) in Google Scholar
Senexin A is an inhibitor of CDK8/19 (IC50: 280 nM, CDK8) and an inhibitor downstream of p21 transcription. It only inhibits p21-induced transcription but does not inhibit other biological effects of p21. Senexin A inhibits CMV-GFP induction as well as the p21 stimulatory activity of the consensus NF-κB-dependent promoters.

Senexin A inhibits CDK8 and CDK19 ATP site binding with Kd50 of 0.83 μM and 0.31 μM, respectively[1].
Senexin A inhibits β-catenin-dependent transcription in HCT116 colon cancer cells[1].
In HT1080 cells, Senexin A strongly inhibits the induction of the transcription factor EGR1 upon serum starvation[1].
Senexin A also reduces the expression of many secreted tumor-promoting factors in doxorubicin-treated wild-type HCT116 cells[1].

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.

Protocolo
Mice: Senexin A toxicity study is conducted by Taconic in C57BL/6 mice, using five mice per group treated with 20 mg/kg Senexin A or carrier (80% propylene glycol), with five daily i.p. injections. Mice are weighed on days 3 and 6, and killed on day 6. Organ weights are determined for brain, kidney, thymus, spleen, lung, and liver. Terminal blood samples are analyzed to determine the numbers of total white blood cells, neutrophils, lymphocytes, monocytes, eosinophils, and basophils[1].
