| Description | KL4-219A is a selective covalent degrader of the oncogenic transcription factor MYC, inhibiting MYC transcriptional activity and degrading MYC in a proteasome-dependent manner by targeting intrinsically disordered C203 and D205 residues. |
| Targets&IC50 | HDAC11:4.5 nM |
| In vitro | KL4-219A potently inhibits HDAC11 in human cancer cell lines such as MDA-MB-231 and HCT116, with an IC₅₀ of 4.5 nM. KL4-219A increases H3K9 acetylation levels and boosts IL-10 expression in vitro. KL4-219A also suppresses MYC expression in immune cells and modulates pathways related to inflammation and metabolism[1]. |
| In vivo | In C57BL/6J mice, KL4-219A was administered intraperitoneally at 50 mg/kg daily for 14 days, resulting in marked downregulation of MYC and upregulation of IL-10 in tumor tissue. In a breast cancer xenograft model, KL4-219A significantly reduced tumor volume compared to vehicle controls, with no observed toxicity[1]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
