EN4 是一种靶向 M??YC 的半胱氨酸 171 (C171) 的共价配体。它抑制 MYC 转录活性，下调 MYC 靶标，并具有抗肿瘤作用。它对c-Myc的选择性高于 N-MYC 和 L-MYC。

EN4 MYC inhibitor is a covalent ligand that targets cysteine 171 (C171) of MYC. It is selective for c-MYC over N-MYC and L-MYC, and inhibits MYC transcriptional activity, downregulates MYC targets, and impairs tumorigenesis.

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.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.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.EN4 (50 μM;?for 2 hours) treatment significantly reduced MYC thermal stability in 231MFP breast cancer cells.
