SEC inhibitor KL-2
Based on 1 publication(s) in Google Scholar
SEC inhibitor KL-2 (KL-2), a peptidomimetic lead compound, is a potent, selective super elongation complex (SEC) inhibitor and disrupts the interaction between the SEC scaffolding protein AFF4 and P-TEFb, resulting in impaired release of Pol II from promoter-proximal pause sites and a reduced average rate of processive transcription elongation. SEC inhibitor KL-2 exhibits an dose-dependent inhibitory effect on AFF4-CCNT1 interaction with a Ki of 1.50 μM.

SEC[1]
In Vitro
SEC inhibitor KL-2 (20 μM, 6 hours) significantly slows Pol II transcription elongation rates and increases Pol II accumulation at promoter-proximal regions in HEK293T cells[1]. SEC inhibitor KL-2 (20 μM, 24 hours) significantly inhibits MYC transcriptional programs and RNA splicing-related gene expressions in HEK293T cells[1].

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.
