Sample solution is provided at 25 µL, 10mM.
EN4 is a covalent ligand that targets cysteine 171 (C171) of MYC. EN4 is selective for c-MYC over N-MYC and L-MYC. EN4 inhibits MYC transcriptional activity, downregulates MYC targets, and impairs tumorigenesis[1].
EN4 (1-50 μM; for 72 hours) treatment significantly impaires 231MFP breast cancer cell proliferation in a dosedependent manner, with >90% inhibition of proliferation at 50 μM[1].EN4 (50 μM; for 60 hours) treatment significantly decreases the protein levels of representative MYC-regulated target genes, including CDK2 and CDC25A. EN4 treatment also substantially reduces MYC levels[1].EN4 shows the strongest inhibition of both MYC/MAX binding to its DNA consensus sequence in vitro as well as MYC transcriptional activity in cells. EN4 inhibited MYC/MAX binding to the E-box response element DNA consensus sequence in a dose-responsive manner with an IC50 value of 6.7 μM. EN4 also inhibits MYC luciferase reporter activity in a dose-responsive manner with an IC50 value of 2.8 μM[1]. EN4 (50 μM; for 2 hours) treatment significantly reduced MYC thermal stability in 231MFP breast cancer cells[1].
EN4 (50 mg/kg; intraperitoneal injection; daily; for 3 weeks) treatment significantly attenuated tumor growth in 231MFP breast tumor xenograft mice[1].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Calculation results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
