Biological Activity
SEC[2]
SEC inhibitor KL-1 (0-100μM, 24-72h) inhibits the growth of DIPG cells and increases apoptosis[1].
SEC inhibitor KL-1 for H3 wild-type astrocytes, the h3g34v mutant glioma cells, and NHA cells with IC50 are 18, 16 and 18μM, respectively[1].
SEC inhibitor KL-1 disrupts SEC, leading to increase occupancy of Pol II near the promoter, which can delay Pol II mutants and slow down Pol II's elongation rate[2].
SEC inhibitor KL-1 (5h) blocks the induction of heat shock-induced genes FOS, HSPD1, HSPE1, and EGR1 in HCT116 cells, impairing the heat shock response[2].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.08 mg/mL (6.02 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
